During the production process, PVC raw materials are mixed and fed into the extruder, where they are heated, conveyed, mixed, and plasticized within the barrel. The molten material is extruded through a specialized die to form the target cross-section, and then undergoes shaping, cooling, traction, and cutting to finally obtain the finished profile that meets the requirements.
Typical Production Flow:
PVC Raw Material → Mixing → Feeding → Extrusion Plasticization → Die Forming → Shaping → Cooling → Traction → Cutting → Finished Product
This production line can be customized according to the specific product’s cross-sectional shape, size, material formulation, and production volume requirements.
| Extruder mold | Main motor (kw) | Working Width (mm) | Capacity(kg/h） |
| 51/105 | 18 | 0-300 | 100 |
| 55/110 | 22 | 0-300 | 150 |
| 65/132 | 37 | 0-600 | 150-200 |
| 80/156 | 55 or 75 | 0-600 | 250-400 |
① Stable Extrusion Plasticization
A suitable extrusion system is configured according to the PVC material and product requirements, ensuring good plasticization and mixing of the raw materials, providing a foundation for stable molding.
② Dedicated Extrusion Dies
Dedicated dies are designed according to the cross-sectional structure of the Accessory Profile, allowing molten material to enter the die channel evenly and form the desired profile shape.
③ Precise Shaping and Cooling
The shaping and cooling system stabilizes the profile dimensions and cross-sectional shape, reducing deformation during production and improving finished product consistency.
④ Stable Traction
The traction machine continuously conveys the molded profile and adjusts the traction speed according to product specifications, maintaining coordination between extrusion speed and traction speed.
⑤ Automatic Fixed-Length Cutting
The cutting equipment can cut continuous profiles to a set length, improving production efficiency and facilitating subsequent packaging and transportation.
⑥ Flexible Product Adaptability
By changing dies and adjusting production parameters, the machine can adapt to the production needs of Accessory Profiles with different structures and sizes.
Step 1 — Raw Material Mixing
PVC resin, stabilizers, fillers, pigments, and other additives are mixed according to the product formulation.
Step 2 — Feeding
The mixed material is fed into the extruder via an automatic feeding system.
Step 3 — Extrusion & Plasticizing
The extruder conveys, heats, mixes, and plasticizes the PVC material, bringing it to a molten state suitable for extrusion.
Step 4 — Profile Forming
The molten material is extruded through a specialized die to form the target cross-section of the accessory profile.
Step 5 — Calibration & Cooling
The profile undergoes shaping and cooling, gradually stabilizing its cross-sectional shape and dimensions.
Step 6 — Hauling & Cutting
The traction machine continuously feeds the profile, while the cutting machine automatically cuts it to a preset length.
Step 7 — Collection
The cut profiles are inspected, collected, and sorted.
① Control Raw Material Formula
PVC raw materials and additives should be mixed according to a stable production formula to avoid significant formula changes affecting plasticization and molding effects.
② Set Extrusion Temperature Appropriately
Different PVC formulas and product specifications require corresponding processing temperatures. Excessive temperature should be avoided to prevent material decomposition.
③ Check the Mold
Before starting the machine, check that the mold is clean and confirm that the mold installation position and runner condition are normal.
④ Maintain a Stable Cooling System
Check the cooling water supply, water temperature, and circulation system to ensure that the profile can be cooled and shaped in a timely manner.
⑤ Match the Traction Speed
The traction speed needs to be coordinated with the extrusion speed. If the product dimensions change during production, the relevant parameters should be adjusted promptly.
⑥ Regular Equipment Maintenance
Regularly inspect the extruder, transmission system, shaping and cooling system, traction machine, cutting machine, and electrical control system, and promptly address any abnormalities.
