  • How to make the Square Plastic Tubing?

To make a PVC box hollow square tubing, first we need to prepare the tube tooling according to the pipe dimension as request. We have a fully equipped in-house die tooling facility that can do this with 7-10 working days. The plastic hollow square tubing is made by our single or co-extrusion process which is a continuous process of shaping a fixed, cross-sectional profile by forcing raw materials in the form of plastic granules through the prepared die. Usually we can send out the the square pipe samples by the new tooling within 15 working days and plus 3 -7 days for mass production.
