Product Description
The SBP Series PVC WPC PP Plastic Plate/Sheet Production Line by Chenxing Machinery is a fully automated, multi-material sheet extrusion system engineered for high-volume, high-precision production. Designed to process PVC (Polyvinyl Chloride), WPC (Wood Plastic Composite), and PP (Polypropylene), this line delivers rigid boards, flexible films, foam-core sheets, decorative panels, and co-extruded laminates with consistent quality and tight dimensional tolerances.
Built around an SJ-type twin-screw extruder with a specialized mixing section, a clothes-rack model die with throttling control, and a multi-roller calibration stage with double-circulation cooling, the SBP series achieves industry-leading thickness accuracy (±0.1 mm) and temperature stability (±1°C). Four standard models span product widths from 850 mm to 1,850 mm, with installed power ranging from 128 kW to 210 kW, making the line suitable for small workshops scaling up to full-scale industrial plants.
The SBP series is a core solution within the broader pipe extrusion line and sheet extrusion portfolio offered by Chenxing Machinery, complementing our PVC WPC foam board extrusion line and PVC hot-cutting pelletizing line for customers who need an end-to-end plastics processing ecosystem.
The front end of the SBP line integrates an automated feeding station consisting of a hopper, a screw feeder automatic feeding machine, a vibrating feeder, and a gravimetric metering-and-weighing unit. This arrangement supports multi-ingredient recipes — PVC powder blended with calcium carbonate, wood flour, stabilizers, and WPC coupling agents — ensuring batch-to-batch consistency. Upstream preparation may involve a high-speed mixer for hot/cold blending and a plastic grinding machine or disc grinding pulverizer SMF pulverizer for powder-size reduction of recycled flakes.
At the heart of the line is the SJ-type twin-screw extruder (conical or parallel configuration), available in 65/33, 75/33, and 90/33 specifications. The screws feature a proprietary mixing-section geometry that combines dispersive and distributive mixing, producing a homogeneous melt with uniform color and high gloss — critical for visible-surface applications like decorative wall panels and furniture boards. A hydraulic quick-opening barrel reduces downtime during material changeovers and simplifies screw cleaning. After pelletizing scrap from cutting operations, recycled material can be re-introduced via a plastic crusher and a plastic pelletizer, closing the material loop.
The melt exits through a clothes-rack model die (coat-hanger manifold) engineered with a precision throttling bar and adjustable lip gap. This die geometry distributes flow uniformly across the full sheet width, enabling transverse thickness deviation below ±0.1 mm when combined with the downstream hydraulic calibration roll-gap control.
Immediately after the die, the sheet enters a multi-roller calibration stand with double-circulation temperature control. The polished, chrome-plated rollers are arranged in a vertical/horizontal stack (optionally tilting to 45°) with individually adjustable roller gaps. An independent oil-pressure pressing system — dual-loop control of hydraulic pressure and oil volume — fine-tunes the nip gap in real time, holding thickness tolerance at ≤ ±0.1 mm across the full line speed range. Temperature-stabilized water circuits (±1°C) prevent thermal shock and ensure uniform cooling, which is particularly important for WPC sheets containing heat-sensitive wood fiber. An SML water-cooled chiller or SML air-cooled chiller / industrial chiller can be integrated into the cooling loop for plants where feed-water temperature is inconsistent.
The haul-off unit employs caterpillar-type or rubber-roller traction with a servo-driven four-axis automatic tension control system. This prevents elongation, wrinkling, and wave distortion, especially on thin-gauge flexible sheets. An optional surface-treatment station — embossing roller, lamination unit, or UV coating applicator — can be inserted between the haul-off and cutting stages to add wood-grain, stone, or gloss textures inline.
The flying saw cutter uses a reciprocating motion synchronized to line speed via servo feedback, delivering cut-length accuracy of ±1 mm and clean edges without dust. Integrated automatic counting and a break-detection auto-stop function reduce scrap and operator intervention. This fly-knife concept is similar in precision to our dust-free pipe cutter / pipe cutting machine technology adapted for flat sheet.
Stacking is handled by a conveyor-belt system feeding a lifting table and optional robotic palletizer, producing neat, counted stacks ready for strapping and shipment. For pipe coiling operations in multi-product factories, we also offer the pipe coiler pipe winding machine and for downstream pipe processing, the pipe belling machine pipe socketing station.
All subsystems are governed by a centralized PLC controller with an HMI touchscreen. The control architecture provides recipe storage (material type, temperature profile, line speed, roller gaps), real-time fault diagnosis, and optional remote IoT connectivity for predictive maintenance and production analytics.

The SBP series employs a dual-loop hydraulic thickness regulation system that simultaneously controls oil pressure and oil volume to the calibration roller nip. Combined with the clothes-rack die's transverse throttling bar, this system achieves thickness uniformity within ±0.1 mm across the full sheet width. For applications requiring tight gauge tolerances — such as WPC flooring substrates, medical-grade panels, and automotive interior trim — this precision eliminates post-production planing or sanding, saving material and labor.
Closed-loop PID temperature regulation across all barrel zones, die zones, and cooling rollers maintains melt temperature within ±1°C of setpoint. This stability is critical for WPC formulations containing wood fiber, where overheating causes fiber degradation and discoloration, and under-heating leads to poor surface finish. The result is consistent color, high gloss, and reliable mechanical properties from the first sheet to the last of every batch.
Unlike simpler T-die geometries, the clothes-rack (coat-hanger) manifold with adjustable throttling bar ensures uniform flow distribution across the entire die width. Operators can fine-tune the lip gap at multiple transverse positions to compensate for melt-flow variations, achieving sheet flatness and optical clarity that T-die systems struggle to deliver — especially on wide-format sheets approaching 2,000 mm.
The SJ twin-screw design features a specialized mixing section that balances high shear (for PVC gelation) with gentle dispersion (to preserve wood-fiber integrity in WPC). This geometry yields 15–25% higher plasticizing throughput compared to standard general-purpose screws, reduces melt-temperature peaks that degrade heat-sensitive additives, and produces homogeneous color distribution even in highly filled formulations (up to 60% wood flour in WPC).
A single SBP production line can run rigid PVC sheets, soft PVC films, WPC composite boards, PP sheets, and even co-extruded multi-layer structures (with optional secondary extruder). Quick-change features — hydraulic barrel opening, modular die lips, and recipe-based HMI parameter sets — allow material changeovers in under 60 minutes. This versatility enables manufacturers to serve diverse markets from building materials to packaging without investing in separate dedicated lines.
The multi-roller calibration stand uses independent upper-roller and lower-roller cooling circuits with counter-flow water routing. This double-circulation design extracts heat symmetrically from both sheet surfaces, preventing differential shrinkage that causes warping. The result is a 20–30% reduction in required cooling length compared to single-circuit systems, enabling higher line speeds and reducing factory floor-space requirements.
The Siemens (or equivalent) PLC with color HMI touchscreen provides one-touch recipe switching for different materials and product specifications. Built-in features include automatic sheet counting, gravimetric throughput monitoring, auto-stop on sheet break detection, and a comprehensive fault-diagnosis library with plain-language alarm descriptions. Optional IoT modules enable remote monitoring, production reporting, and predictive maintenance alerts — compatible with Industry 4.0 factory architectures.
Optimized screw geometry reduces specific energy consumption (kWh/kg) by 12–18% compared to previous-generation designs. A closed-loop cooling water system with filtration and recirculation minimizes fresh-water consumption and eliminates thermal discharge. Low-noise operation (below 78 dBA at 1 meter) meets occupational health standards without requiring operator hearing protection enclosures. Material off-cuts from the flying saw can be reground using a disc plastic pulverizer / SMP pulverizer and reintroduced into the extrusion process, achieving near-zero scrap workflows.
An intermediate surface-treatment station can be integrated between haul-off and cutting, supporting hot-embossing rollers (wood-grain, stone, leather textures), cold-lamination of protective PE film or decorative transfer foil, and UV-curable coating application for enhanced scratch and chemical resistance. This eliminates the need for a separate offline finishing line, reducing handling costs and production lead time.
The downstream handling system — conveyor belt, scissor-lift stacking table, and optional six-axis robotic palletizer — automatically collects, counts, aligns, and stacks cut sheets into neat pallet-loads. Integration with the PLC counter ensures exact sheet-count per stack, while the lift table's descending motion maintains a constant drop height to prevent edge damage on brittle foam boards or thin-gauge sheets.
The SBP series sheet production line transforms raw plastic granules or powder into finished, dimensionally accurate sheets through a seven-stage continuous process:
Stage 1 — Raw Material Feeding & Dosing
PVC/WPC/PP feedstock (granules or powder) is loaded into a hopper with screw feeder / automatic feeding machine and vibratory feeder. A gravimetric dosing unit meters each component — base resin, wood flour, calcium carbonate, stabilizers, lubricants, impact modifiers, and pigments — according to the stored recipe. Pre-blending in a high-speed mixer ensures uniform additive distribution before the dry blend enters the extruder throat.
Stage 2 — Twin-Screw Plasticizing & Homogenization
The dry blend enters the heated barrel of the SJ twin-screw extruder. Counter-rotating (or co-rotating, depending on configuration) screws convey the material through multiple temperature zones (typically 160–220°C, depending on polymer type). The specialized mixing section applies controlled shear to fully gelate PVC particles, disperse wood fiber without thermal degradation, and homogenize all additives into a uniform melt with consistent color and viscosity. A vacuum vent port removes residual moisture and volatiles.
Stage 3 — Clothes-Rack Die Extrusion — Sheet Preform Formation
The homogeneous melt is pushed through the clothes-rack die, where the coat-hanger manifold splits and distributes flow laterally. An adjustable throttling bar fine-tunes the flow resistance at multiple points across the die width, compensating for any viscosity or pressure gradients. The melt exits the die lip as a continuous, flat sheet preform with uniform cross-section.
Stage 4 — Multi-Roller Calibration & Cooling
The hot preform immediately enters the three-roll (or five-roll) calibration stack. The sheet passes between temperature-controlled chrome-plated rollers arranged in a vertical or inclined (45°) configuration. The upper roller applies precisely controlled pressure via the hydraulic oil-volume dual-loop system, setting the final sheet thickness. Double-circulation water cooling symmetrically extracts heat from both sides, rapidly solidifying the sheet while minimizing internal stress. Roller gaps are independently motorized for quick gauge changes.
Stage 5 — Controlled Haul-off with Tension Regulation
The solidified sheet is pulled through the line by a caterpillar-type or rubber-roller haul-off unit. A servo-driven four-axis automatic tension control system maintains constant pulling force, preventing stretch deformation in flexible films and surface scratching in rigid boards. The haul-off speed is synchronized with the extruder screw RPM via the central PLC to maintain consistent gauge.
Stage 6 — Inline Surface Finishing (Optional)
Between haul-off and cutting, the sheet can pass through an optional surface-treatment station — embossing rollers for textured finishes, a lamination unit for protective film application, or a UV coating head for functional topcoats. This inline approach eliminates secondary handling and reduces total production cycle time.
Stage 7 — Automatic Cutting, Stacking & Palletizing
A flying saw cutter — synchronized to line speed via servo feedback — cleanly cross-cuts the continuous sheet at the programmed length (±1 mm accuracy). The integrated counter tracks sheet count and triggers an auto-stop if a sheet break is detected. Cut sheets are conveyed to a lifting table that descends incrementally to maintain constant drop height, stacking finished boards neatly. An optional robotic palletizer picks and places stacks onto pallets, ready for strapping, stretch-wrapping, and warehouse dispatch.
End-of-line scrap from edge trimming or off-spec sheets can be fed into a plastic crusher and then reground using a disc grinding pulverizer / SMF pulverizer, with the resulting powder reintroduced into the extrusion feedstream — creating a virtually closed-loop material cycle.
PVC and WPC sheets from the SBP series are widely used in modern construction: interior and exterior wall cladding panels (wood-grain and stone-texture finishes), waterproof partition boards, suspended ceiling panels, skirting boards, and WPC concrete formwork boards that replace traditional plywood with better reusability and moisture resistance. For high-rise buildings, the fire-retardant PVC foam-core sheets meet Class B1 flammability standards (with proper formulation).
Cabinet door panels, wardrobe boards, desk tops, and bookshelf panels produced on SBP lines offer consistent color, scratch resistance, and zero formaldehyde emission — meeting E0/E1 standards for indoor furniture. The ability to emboss wood-grain textures inline creates realistic aesthetic finishes without the cost of real wood veneer. Eco-friendly children's furniture, bathroom vanities, and modular kitchen components are all typical downstream products.
Bus interior wall panels, truck partition boards, RV sidewall laminates, and marine cabin decorative panels all benefit from the lightweight, water-resistant, and impact-tolerant properties of PP and PVC sheets produced on SBP lines. The ±0.1 mm thickness tolerance is critical for snap-fit automotive trim components that must mate with injection-molded clips and brackets.
PVC foam boards (also known as Foamex or Forex) produced on this line are the standard substrate for exhibition display panels, point-of-sale stands, screen-printing boards, light-box backings, CNC-router engraved signage, and photo-mounting boards. The smooth, bright-white surface provides an excellent base for direct digital printing and vinyl application. PP corrugated sheets are used for reusable election campaign boards and outdoor real-estate signage.
Anti-corrosion laboratory worktops, operating-room wall panels, and clean-room partition boards require the chemical resistance and non-porous surface that rigid PVC and PP sheets provide. With appropriate clean-grade formulation and post-extrusion surface treatment, SBP-produced sheets meet the hygiene and cleanability requirements of ISO Class 7 (Class 10,000) cleanrooms.
Moisture-proof pallet covers, reusable turnover-box lids, dunnage boards, and industrial buffer sheets in PP and HDPE variants are produced for logistics and warehousing operations. The sheets are stackable, washable, and resistant to oils and mild chemicals, offering a longer service life than corrugated cardboard alternatives.
Although PC and PMMA multi-wall sheets require specialized downstream equipment, the SBP line can produce PVC greenhouse glazing panels and agricultural trough liners. PP sheets are used for nursery tray bases and hydroponic system partitions where UV-stabilized formulations provide multi-season outdoor durability.
PP and PVC sheets serve as backing support panels in solar PV module frames and as electrical insulation barriers in switchgear and control cabinets. Custom-formulated anti-static PVC sheets are used in electronics manufacturing cleanrooms, while flame-retardant grades are specified for railway rolling-stock interior panels.
WPC substrate boards for click-lock luxury vinyl tile (LVT) flooring, sports-mat underlay sheets, and gym shock-absorption panels are all high-growth applications where the SBP line's tight thickness control and wood-fiber compatibility provide a competitive edge in the flooring supply chain.
Integrated Ecosystem Support. Unlike stand-alone machine suppliers, Chenxing Machinery delivers a complete upstream-downstream equipment package — from raw-material preparation (high-speed mixer, screw feeder automatic feeding machine, plastic grinding machine) to post-extrusion processing (plastic crusher, plastic pelletizer, disc grinding pulverizer SMF pulverizer, pipe extrusion line) — ensuring seamless compatibility and single-source accountability.
Proven Twin-Screw Expertise. Our engineering team has deep domain knowledge in PVC and WPC compounding, honed across hundreds of installed PVC WPC foam board extrusion line and PVC hot-cutting pelletizing line projects worldwide. The SBP screw geometry is the result of iterative CFD simulation and field validation, not off-the-shelf catalog specifications.
Factory Acceptance Testing (FAT). Every SBP line undergoes a complete dry-run and material trial at our Zhangjiagang factory before shipment. We invite customers to witness the FAT, verify output rates, measure sheet samples for thickness and surface quality, and sign off on acceptance protocols before crating and shipping.
Turnkey Installation & Training. Our service engineers travel to your facility for mechanical installation supervision, electrical commissioning, operator training, and first-batch production support. A remote diagnostic link can be established post-commissioning for ongoing technical support, minimizing downtime for overseas customers.
Rapid Spare Parts Availability. A comprehensive spare-parts inventory — screws, barrels, roller bearings, heating bands, temperature sensors, hydraulic seals — is maintained at our factory and regional service centers. Critical wear parts are stocked in standard sizes, with custom items available within agreed lead times.
For factories expanding beyond sheet extrusion into pipe production, we recommend reviewing our complementary pipe extrusion line equipment, including the caterpillar haul-off machine pipe haul-off, dust-free pipe cutter pipe cutting machine, pipe coiler pipe winding machine, pipe belling machine pipe socketing, and reinforced pipe production line / spiral hose extrusion systems — all of which integrate with the same PLC control architecture and shared utility infrastructure.
Yes. The SBP series is designed for quick material changeovers. For rigid PVC sheets (typically 1–18 mm), the calibration roller gaps, die lip opening, cooling water temperature setpoints, and haul-off tension parameters are all stored as PLC recipes. Switching to flexible film (0.5–2 mm) requires loading the film recipe, adjusting the roller gap and die lip, and optionally engaging the winding station instead of the flying saw. The hydraulic barrel opening allows rapid screw cleaning if cross-contamination risk exists (e.g., switching from dark-colored WPC to white PVC). Most operators complete a full changeover within 45–60 minutes. The only hardware addition for film production is a surface winder or turret winder, which we can supply as an optional module. For customers who run both rigid and flexible products daily, we recommend the SBP1800 or SBP2000 model, which provides the widest operating window and highest throughput flexibility.
For a typical WPC formulation — 60% wood flour (80–120 mesh), 30% PVC or PE matrix, 5% coupling agent (MAPE/MAPP), and 5% lubricant/stabilizer package — running on the SBP1400 (1,250 mm product width, SJ 75/33 extruder), the sustainable output rate is approximately 200–260 kg/h at 10 mm thickness. This translates to roughly 3.8–5.0 linear meters per minute for 1,220 mm × 10 mm boards. Actual throughput depends on wood-flour moisture content (must be below 1.5%), bulk density, and the specific lubricant package. The specialized mixing-section screw is the key enabler: its geometry prevents wood-fiber charring even at sustained high throughput, which is the primary bottleneck in WPC extrusion. We can provide a detailed throughput simulation based on your exact formulation upon request.
Thickness uniformity on wide-format sheets is achieved through three complementary systems. First, the clothes-rack die manifold geometry ensures equal flow-path length from the inlet to every point along the die lip, eliminating the center-thicker/edge-thinner pattern typical of simple T-dies. Second, the die's adjustable throttling bar allows the operator to fine-tune the flow resistance at 5–7 discrete points across the width, compensating for any formulation-related viscosity gradients. Third, the hydraulic calibration roller system applies independent pressure control on the left and right sides of the upper roller, dynamically correcting any transverse gauge variation detected by the inline laser thickness gauge. On factory acceptance tests, the SBP2000 consistently holds ±0.08 mm across the center 1,600 mm and ±0.1 mm at the outer 125 mm edges, measured at 1-meter intervals along the sheet length.
A standard SBP installation requires: (a) Three-phase electrical power — 380V/50Hz or 440V/60Hz (transformer sizing based on installed power plus 20% overhead for auxiliary equipment); (b) Cooling water supply — 10–25 m³/h at ≤25°C inlet temperature and 2–3 bar pressure, preferably from a closed-loop SML water-cooled chiller or SML air-cooled chiller / industrial chiller system to maintain ±1°C stability; (c) Compressed air — 6–8 bar, oil-free, for pneumatic actuators and die-lip adjustment cylinders; (d) Factory floor — level concrete slab rated for 2,000 kg/m² point loads at roller-stand footings, with service trenches for water and power routing; (e) Overhead clearance — minimum 4.5 meters for the SBP2000 to accommodate the roller stack height plus safe maintenance access. We provide a detailed site-preparation drawing (foundation plan, utility connection points, and load distribution) 60 days before shipment.
Yes, co-extrusion capability is available as an optional configuration. The standard setup adds a secondary single-screw or small twin-screw extruder (typically SJ 45/30 or SJ 50/30) that feeds a co-extrusion feedblock and multi-manifold die adapter upstream of the main clothes-rack die. This enables A/B/A or A/B layer structures — for example, a thin ASA weatherable cap layer (0.2–0.5 mm) on a WPC core for outdoor decking, or a virgin PVC surface layer on a recycled-PVC core for cost-optimized wall panels. The co-extrusion feedblock includes adjustable flow vanes to control layer distribution ratios. The HMI recipe system stores separate temperature and RPM profiles for the co-extruder. For three-layer (A/B/C) structures requiring two different surface materials, a second co-extruder can be added. We recommend discussing your target layer structure with our application engineers so we can specify the optimal feedblock geometry and die-land configuration.
The SBP series is covered by an 18-month warranty from the date of shipment (or 12 months from commissioning, whichever is later), covering manufacturing defects in materials and workmanship on all mechanical components. Electrical components (PLC, HMI, servo drives, temperature controllers) carry the original manufacturer's warranty (typically 12 months). Our standard after-sales package includes: (a) two weeks of on-site installation supervision and commissioning by a senior engineer; (b) operator and maintenance training (classroom + hands-on) for up to 5 personnel; (c) one set of printed operation and maintenance manuals in English; (d) 24/7 remote technical support via WhatsApp/WeChat/TeamViewer for the first 12 months of production. Extended warranty and annual preventive-maintenance service contracts are available. For overseas customers without in-house maintenance capability, we can station a service engineer on-site for 1–3 months post-commissioning at a negotiated daily rate plus expenses.
Absolutely. The SBP line is designed to accommodate regrind in the feedstock stream. Edge-trim scrap, off-spec sheets, and start-up waste can be processed through a plastic crusher to reduce them to flakes (8–12 mm), then pulverized in a disc grinding pulverizer / SMF pulverizer to achieve a powder fineness of 40–80 mesh. This powder can be metered back into the feeding system at rates of 10–30% of total feedstock (depending on formulation and end-product quality requirements) without noticeable degradation in mechanical properties or surface finish. For WPC formulations, regrind incorporation up to 20% is standard. The gravimetric dosing unit ensures consistent regrind-to-virgin ratio, and the mixing-section screw geometry re-homogenizes the blend effectively. This closed-loop recycling capability typically reduces raw-material cost by 8–15% and eliminates disposal costs for production scrap, contributing to both economic and environmental sustainability targets.
