During production, PVC raw materials first pass through a mixing and feeding system into the extruder, where they are heated, conveyed, mixed, and plasticized inside the barrel. The molten material is then extruded through a specialized die to form the desired cross-section, followed by shaping, cooling, traction, and cutting to finally obtain edge profiles that meet the required length.
Typical Production Flow:
PVC Raw Material → Mixing → Feeding → Extrusion Plasticization → Die Forming → Shaping → Cooling → Traction → Cutting → Finished Product
Depending on product requirements, laminating, printing, or other surface treatment equipment can also be added to the production line.
| 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 PVC Extrusion System
A suitable extrusion system is configured according to the characteristics of PVC material, ensuring stable plasticization and uniform melt flow, providing a stable foundation for profile forming.
② Dedicated Edge Profile Dies
Die design is based on the product cross-section and dimensions provided by the customer, allowing molten PVC material to be continuously extruded according to the target shape.
For edge profiles of different specifications and cross-sections, product switching can be achieved by changing the corresponding die.
③ Precise Shaping and Cooling
After the profile exits the die, it needs to be shaped and cooled promptly.
The shaping and cooling system helps control product dimensions, cross-sectional shape, and surface quality, and improves the stability of the profile production process.
④ Stable Traction
The traction machine continuously conveys the formed edge profiles forward.
By properly matching the extrusion speed and traction speed, problems such as dimensional changes, bending, or deformation of the profiles during production can be reduced.
⑤ Automatic Fixed-Length Cutting
The cutting system cuts continuous profiles to a preset length, ensuring consistent finished product length for convenient packaging, transportation, and use.
⑥ Flexible Production Configuration
The entire production line can be customized to meet different customer needs, including:
Step 1 — Raw Material Mixing
According to the product formulation, PVC resin, stabilizers, fillers, pigments, and other additives are thoroughly mixed.
Step 2 — Feeding
The mixed PVC material is fed into the extruder via an automatic feeding system.
Step 3 — Extrusion and Plasticizing
The extruder heats, conveys, mixes, and plasticizes the PVC material, creating a uniform molten state.
Step 4 — Profile Forming
The molten PVC is continuously extruded through specialized edge profile dies to form the desired product cross-section.
Step 5 — Calibration and Cooling
The profile undergoes a sizing and cooling system to gradually stabilize the product and maintain the required dimensions and shape.
Step 6 — Hauling and Cutting
The traction machine steadily conveys the profile forward, and the cutter automatically cuts it to the set length.
Step 7 — Collection
After inspection, the finished products are collected and organized by a stacking rack for subsequent packaging.
① Ensure Uniform Raw Material Mixing
PVC raw materials and various additives need to be thoroughly mixed according to the formula.
When the raw material formula changes, the extrusion temperature and production parameters should be readjusted.
② Reasonably Control Processing Temperature
PVC is sensitive to temperature; the temperature of each zone should be set reasonably according to the specific formula and equipment configuration.
Avoid excessively high temperatures that cause material decomposition, and avoid insufficient temperatures that lead to incomplete plasticization.
③ Monitor Mold Condition
Before production, check that the mold is clean and the runner is functioning properly.
When changing product specifications, ensure that the mold and product cross-section match.
④ Maintain Normal Operation of the Cooling System
Check the water pump, cooling water pipeline, and shaping device before production.
Stable cooling conditions help control the size and shape of Edge Profiles.
⑤ Reasonably Adjust the Traction Speed
The traction speed needs to match the extrusion speed.
If the traction speed and extrusion speed are not coordinated, it may lead to changes in profile dimensions or deformation.
⑥ Perform regular equipment maintenance
Regularly inspect the extruder, transmission system, vacuum system, cooling system, traction machine, cutting machine, and electrical control system.
