Modern LED lighting is no longer a single white tube clipped into a ceiling. Buyers order translucent covers in two contrasting colors, diffusers with one color band and a clear body, and lampshades matched to the decoration theme of a hotel lobby, supermarket aisle or KTV booth. Yet many profile makers still discover the same five bottlenecks the moment a double-color order lands on their desk.
A single-color line can only deliver a single-color cover. When a customer asks for a lamp tube with two different colors in one integral profile, the producer either turns the order away or pays another factory to make it, losing margin and control.
Response: Chenxing Machinery configures this line with two single screw extruders co-extruding into one die, so the same machine makes single-color profiles with one extruder and true two-color integral profiles with two. One investment covers both order types, and the rest of the line — calibration, haul-off, cutting and stacking — stays identical.
Two colors that fuse into one muddy band, or a seam that drifts from run to run, are instantly visible on a translucent PC cover. The cause is usually uneven melt temperature between the two screws or a downstream speed that fights the die.
Response: the main and satellite screws run as one synchronized extrusion train with independent temperature control, while the upper and lower haul-off units are driven separately with inverter speed control. The profile is pulled at a constant, repeatable rate so the color boundary stays clean from die face to cutting station.
PC is tougher on tooling than ordinary soft PVC. Standard carbon steel dies erode quickly, and a rough die surface marks an otherwise clear cover with drag lines.
Response: the die head is machined from 3Cr13/3Cr17 stainless tool steel and developed specifically for PC material calibration. The PC LED light cover extrusion line family uses the same die philosophy — harder steel, polished flow channels and PC-specific geometry — to extend die life and keep the profile surface smooth.
LED tube diameters changed as the industry moved from T12 to T8, then to slimmer T5 and T3 models. A producer who can only pull one width watches catalog demand pass to competitors.
Response: the calibration table is 100 mm wide and 4000 mm long, with interchangeable dies and down-line tooling covering T3, T5, T8 and T12 LED models. Width changeovers are handled with the same extruder pair, so one double-color line serves the full LED tube family.
An extrusion line runs 24 hours a day across borders. If the electrical cabinet fails on a Sunday shift in another country, the producer needs answers, not a ticket queue.
Response: this line is built with Siemens/WEG original motors and ABB inverters, world-famous brands with global service networks, and Chenxing backs every line with a 5-year warranty and after-sales service.

The Double Color PC Lamp Light LED Tube Line — also configured as a PC Cover Profile Production Machine — is a single-screw extrusion system designed for making PC, PMMA and ABS lamp tubes, lamp shades and cover profiles used in LED lighting decoration. The machine is specially designed to make PC tube/profile as LED light, with one color separated, or two different colors in an integral structure.
The final PC tube or profile is suitable for T3, T5, T8 and T12 LED light models. Whether you run a standard white translucent cover for a supermarket ceiling or a two-color lampshade for a KTV wall panel, this line delivers the clean geometry and color separation that lighting buyers expect.
Configuration is matched to the product, never the other way around:
Single-color profiles need one single screw extruder. Depending on the profile width specification, Chenxing equips the line with the corresponding SJ55, SJ50 or SJ45 single screw extruder.
Two-color pipes or profiles need two single screw extruders running co-extrusion into one die, producing one profile with two integral color zones in a single pass.
From hoppers and dryers to the mixing and material feeding units, every station is selected to hold the melt temperature stable — the foundation of clean double-color extrusion. More production references and line configuration notes are available at view more machine details.
Every station below is included to keep the profile dimensionally stable and the color boundary sharp:
| Station | What It Does in This Line |
|---|---|
| Hopper dryer | Feeds and dries material into the extruder, removing moisture that would cause bubbles in clear PC covers. |
| Extruder | World-famous brand electrical components — Siemens, ABB etc.; high-torque gearbox with adopted bearing; Siemens/WEG original motor for global after-service. |
| Die head | 3Cr13/3Cr17 material, developed specially for PC material moulding. |
| Calibration table | Width 100 mm, length 4000 mm — sizes and cools the profile to final tolerance. |
| Haul-off | Upper/lower drives run separately with inverter speed control for constant, strain-free pulling. |
| Cutter | Synchronous driving by air cylinder or servo motor for square, burr-free cuts. |
| Stacker | Stainless steel 304 as the material-touching surface to protect the finished profile. |
| Model | Screw Diameter (mm) | Main Motor (kW) | Output Capacity (kg/h) |
|---|---|---|---|
| SJ55 | 55/28 | 18.5 | 50–60 |
| SJ65 | 65/28 | 22 | 60–80 |
The values shown as 55/28 and 65/28 refer to screw diameter / L/D ratio. Choose SJ55 for compact covers and SJ65 when the order book demands higher throughput on wider profiles; both models share the same downstream train, so upgrading later only changes the extruder module.
Capable of producing single or two different color PC/PMMA profiles with integral structure — no assembly, no adhesive, no second pass. Two extruders feed one die and the colors fuse at the flow junction for a permanent, machine-made bond.
Suitable for T3, T5, T8 and T12 LED light models, covering the full range of decoration applications from slim architectural coves to standard ceiling troffers.
Constructed from 3Cr13/3Cr17 material, specifically designed for PC material calibration — the steel choice that keeps the surface of clear and translucent covers free of drag marks.
Siemens/ABB electricals, high-torque gearboxes with adopted bearings and Siemens/WEG original motors give the line the shift-after-shift reliability that LED lighting production schedules demand.
Includes 1 year of after-sales service and warranty coverage for the machine — one of the strongest support commitments in the profile extrusion market.
The PC/PMMA LED lamp profile tube/shade making machine is mainly suitable for making PC and PMMA lamp tube/shade. This lamp tube/shade is widely used in LED lighting decoration, such as:
Outdoor advertising — luminous signs, edge-lit letters and channel letters
Hotels — ceiling coves, wall-wash lighting and decorative screens
Supermarkets & shops — bright translucent troffers and shelf accent light covers
KTV & Disco — colored lampshades and mood-lighting profiles
Automotive — interior accent lighting and trim covers
Home lighting — desk lamps, floor lamps and decorative LED fixturesThe machine is also suitable for PC, PMMA and ABS materials, so when a buyer switches from one material family to another for price or performance reasons, you can retune the same line instead of buying a new one.

Yes. It can produce two different color pipes or profiles by equipping two sets of single screw extruders for co-extrusion into one die. If you only need single-color profiles, one extruder — SJ55, SJ50 or SJ45 depending on profile width — is sufficient.
Chenxing provides a 1-year warranty and after-sales service for all machines, including the double color PC lamp light LED tube line. Siemens/WEG motors and ABB inverters are chosen partly because their global service networks can support your line wherever it is installed.
The profiles are widely used in outdoor advertising, hotels, supermarkets, shops, KTV, Disco, automotive and home lighting, mainly as PC/PMMA lamp tubes, lamp shades and cover profiles for T3, T5, T8 and T12 LED models.
The line is mainly suitable for PC, PMMA and ABS materials for making lamp tubes and shades. The 3Cr13/3Cr17 die head is developed specially for PC material calibration, giving clear and translucent covers a stable, mark-free surface.
The machine uses world-famous brand electrical components such as Siemens and ABB, including Siemens/WEG original motors and ABB inverters, with a high-torque gearbox adopting premium bearings for long service life.
