Product Description
Two-color and three-color PP and PE products — lollipop candy sticks, striped drinking straws, cotton swab sticks and pen refill tubes — are high-volume, low-margin items where every minute of downtime and every rejected meter of color drift cuts directly into profit. Yet many producers still fight the same five battles on every order:
A striped candy stick with a bleeding red layer or a straw whose color band moves out of position is rejected by food-contact and confectionery buyers. Inconsistent melt temperature and poorly synchronized satellite screws are usually the cause.
Response: Chenxing matches the main screw and satellite co-extrusion screws in one synchronized drive train, so every color stream stays uniform from the die face to the cooling bath.
Conventional small-diameter lines pull one stick or one straw at a time. To reach order volumes, producers buy more lines, use more floor space and double their labor — when the machine itself could simply draw two sticks at once.
Response: the dual-cavity die configuration on this line produces two sticks at one time from a single extruder, lifting practical output toward 100-200 kg/h without a second footprint.
Buyers ask for lollipop sticks one month, drinking straws the next, then cotton swab sticks and pen refill tubes. Producers whose die and screw cannot switch families keep idle machines or refuse profitable orders.
Response: by changing the forming die and recalling the process recipe, the same Chenxing line moves between lollipop sticks, drinking straws, cotton swab sticks, pen refill tubes and other small-diameter products.
A hose, cable or relay that fails in the middle of a 24-hour run stops the whole line. Cheap electrical cabinets are the hidden cost of budget machines.
Response: this line is equipped with Siemens motors, ABB inverters and high-grade relays, so the drive train keeps running shift after shift and spare parts are available worldwide.
Switching from single-color to three-color, or from PP to PE, can mean hours of purging and re-tuning on poorly designed lines.
Response: quick-release die mounting, stored recipes and a clear PLC workflow cut color and material changeover from hours to a short, predictable routine.
The Chenxing Two Three Color PP PE Lollipop Candy Stick and Drinking Straw Making Machine, supplied by Zhangjiagang Chenxing Machinery Co., Ltd. (Chenxing Machinery), is a single screw extrusion line purpose-built for small-diameter, multi-color products. With different forming die structures, the same machine produces lollipop candy sticks, drinking straws, cotton swab sticks, pen refill tubes and similar rod and tube items, in single-color, two-color or multi-color versions as your orders require.
The line is designed around two ideas that matter most in this market: color stability and throughput. The main extruder feeds a multi-channel or dual-cavity die while satellite co-extrusion screws inject the second and third color streams, and the machine can be arranged to produce two sticks at one time, which is why the practical output range reaches 100-200 kg/h depending on product diameter and configuration. Downstream, a matched water cooling tank, caterpillar haul-off and cutting device hold roundness and cut quality across the whole shift.
The machine shares its single screw extruder architecture with the rest of the pipe extrusion line family and the single screw extruder platform that Chenxing has refined for over 20 years, so operators moving from our other lines already know the control logic and maintenance rhythm. Electrical and drive components use Siemens motors, ABB inverters and high-grade relays, giving the line the reliability that food-contact and confectionery production schedules demand.
The table below lists the standard extruder configurations for this line. Screw diameter, L/D ratio and main motor power follow the proven 28:1 geometry that balances plastication, mixing and energy use for small-diameter PP and PE products. Product size range means the outside diameter of the stick, straw or tube produced with the corresponding die set.
| Configuration | Screw Diameter (mm) | L/D Ratio | Main Motor Power (kW) | Product Size Range (mm) |
|---|---|---|---|---|
| Single color | ø50 | 28:1 | 7.5 | 1–10 |
| Single color | ø55 | 28:1 | 11 | 2–15 |
| Single color | ø65 | 28:1 | 15 | 3–20 |
| Two color | ø55 + ø25 | 28:1 | 7.5 + 1.5 | 3–15 |
| Three color | ø55 + ø25 × 2 | 28:1 | 11 + 1.5 | 3–15 |
Machine type: single screw extruder with co-extrusion satellite screws. Main material: PP, with PE, HDPE and PPR also supported after recipe confirmation. Output: about 100–200 kg/h depending on configuration, product size and cavity count. Customization: available for die structure, color count, downstream layout and automation level. Warranty: 12 months. Electrical package: Siemens motors, ABB inverters and high-grade relays.
In a single-color layout, one main extruder feeds a conventional die and produces a solid-color stick or straw in the 1–20 mm range. In the two-color layout, a ø25 satellite screw joins the main extruder to add one stripe or second color for 3–15 mm products. In the three-color layout, two ø25 satellite screws create two added color streams, again for 3–15 mm products. Because the satellite screws are synchronized with the main screw, the stripes stay sharp even when line speed changes.
The die can be arranged with two cavities so the line draws two sticks at one time, effectively multiplying the output of a single screw. This configuration is especially valuable for plain drinking straws and cotton swab sticks, where the market buys by the million and the difference between one cavity and two shows up directly on the monthly production report. Tell our engineers your product, diameter and daily order size, and they will confirm whether a single-cavity or dual-cavity die is the right choice in the free technical layout.
Two Sticks at One Time — the dual-cavity die option draws two sticks simultaneously, raising the practical output of one line toward 100–200 kg/h and lowering the cost per thousand sticks.
Stable Multi-Color Quality — synchronized main and satellite screws keep two-color and three-color stripes uniform and free of bleeding, which is what food-contact and confectionery buyers check first.
One Machine, Four Product Families — change the forming die and recall the recipe to move between lollipop candy sticks, drinking straws, cotton swab sticks and pen refill tubes on the same base machine.
PP First, PE and More on Request — the screw and barrel are tuned for PP as standard, while PE, HDPE and PPR can be processed with the corresponding profile, so one line serves conventional and value-line orders.
Proven Single Screw Plastication — the 28:1 screw geometry gives high-speed, high-output plastication with good mixing, holding diameter tolerance and surface quality across the whole shift.
Reliable Drive and Control — Siemens motors, ABB inverters and high-grade relays keep the line running in 24-hour production, and the touch-screen PLC stores recipes for fast product and color changeover.
European-Style Downstream Matching — die, water cooling, haul-off and cutting are engineered as one system, eliminating the ovality, sagging and length errors that appear when stations from different suppliers are connected.
Factory Tested Before Shipment — every line runs a complete machinery test with your material and product sample before packing, then is protected with PE film winding wrapping for ocean freight.
12-Month Warranty and Export Support — as an ISO 9001 certified manufacturer with 20+ years of experience, Chenxing provides overseas installation guidance, operator training, spare parts and remote troubleshooting.

Lollipop Candy Sticks — round and square candy sticks in single or multi colors for confectionery production.
Drinking Straws — plain, striped and multi-color PP drinking straws for juice, milk tea and beverage packaging.
Cotton Swab Sticks — smooth, straight PP sticks for personal care and medical cotton swabs.
Pen Refill Tubes — precise small-diameter tubes for pen refill and stationery manufacturing.
Balloon Sticks — lightweight PP and PE rods for events, gifts and promotional items.
Other Small-Diameter Rods and Tubes — custom small profiles within the 1–20 mm die range for packaging, toys and consumer goods.
If your product portfolio also includes larger pipes or profiles, the same single screw platform extends naturally into our other type pipe extrusion line solution, Profile extrusion line solution and corrugated pipe extrusion line solution, so one supplier can cover your whole factory plan.
With different forming die structures, the same machine produces lollipop candy sticks, drinking straws, cotton swab sticks, pen refill tubes and other small-diameter rod and tube products with outside diameters from about 1 mm up to 20 mm. The base material is PP, with PE, HDPE and PPR available after recipe confirmation. This answer is provided by Chenxing Machinery's extrusion process team.
A single-color configuration uses one main extruder and produces a solid-color product. A two-color configuration adds one ø25 satellite screw to inject a stripe or second color, and a three-color configuration adds two ø25 satellite screws for two extra color streams. The practical difference is visual: striped straws, candy sticks and decorative products need the satellite screws, while plain commodity products do not. This answer is provided by Chenxing Machinery's sales-engineering team based on the standard machine data sheet.
Yes. When the die is arranged with two cavities, the line draws two sticks simultaneously from one extruder, which is how the practical output reaches 100–200 kg/h depending on product diameter and material. The dual-cavity configuration is most valuable for high-volume plain products such as drinking straws and cotton swab sticks. This answer is provided by Chenxing Machinery's engineering team.
You change the forming die and recall the stored recipe for the new product. The die mounting is designed for quick change, and the PLC stores temperature, screw speed and line speed recipes for each product family, so a trained operator can complete the changeover in a short, predictable routine. If you plan to switch families regularly, tell our engineers during the technical layout and we will add quick-release fittings where they help. This answer is provided by Chenxing Machinery's process engineers.
