PVC Twin Wall Hollow Roof extrusion tooling

PVC Twin Wall Hollow Roof Extrusion Tooling Core Knowledge

1. The PVC Twin Wall Hollow Roof Extrusion Tooling boasts strong adaptability. Although the product cross-sectional dimensions are relatively large, the overall wall thickness is thin and the weight per meter is light. It can stably produce on conventional 65/132 and 80/156 extruders, making it highly versatile and easy to adapt to.

2. To meet diverse market demands, this PVC Twin Wall Hollow Roof Extrusion Tooling supports flexible color switching. The equipment comes standard with a white product die head. To produce colored ASA co-extruded roofing tiles, only the two front templates of the die head need to be replaced. It can fully reuse the existing calibrator, water tank, and other auxiliary equipment, requiring no major modifications to the production line. This effectively reduces customer conversion costs and quickly adapts to the production needs of both white and colored products.

3. In practical production, ordinary split-type die heads have significant process limitations. Most similar molds on the market use a two-piece die head connection structure, which is simple to manufacture and low in cost, but has poor stability and is highly susceptible to the influence of raw materials, formula, and extrusion process. This can result in dynamic deviations, such as slower material output on both sides when the speed is increased and faster output on both sides when the speed is decreased. For this structure, simply maintaining a constant extrusion speed can ensure stable production of PVC Twin Wall Hollow Roof Extrusion Tooling.

4. If the mold exhibits a fixed deviation where the material output on both sides is consistently too fast or too slow, this is a mold design defect. It can be precisely adjusted through three solutions: First, temperature adjustment: if the material output on both sides is too fast, lower the temperature by 5-10℃; if it is too slow, raise the temperature appropriately. Second, formula fine-tuning: if the material output on both sides is too fast, reduce the external lubricant by 0.2kg; if the material output is too slow, increase the external lubricant appropriately. Third, mold repair: if process adjustments are ineffective, the problem can be completely resolved by repairing the mold flow channel.
