UPVC pipe fitting supplier

Chinese leading UPVC pipe fitting mold manufacturer –Sino mold will guide you to order good UPVC fitting molds.

I think UPVC pipe fitting manufacturers are very familiar with UPVC particular features:

1. UPVC material is high corrosive

2. UPVC material is very sensitive to temperature

Then what kind of steel is suitable for UPVC pipe fitting mold?

Only stainless steel like:H13, DIN1.2316 and S420 is suitable.

If you got a pipe fitting mold quotation P20 or 718H steel, apparently, this is not professional! Cheap price, but bad quality! Because P20 and 718H steel are not stainless steel, as PVC material is corrosive, molds easily go rusty. Therefore, UPVC pipe fitting mold can only use stainless steel and also deep hardened to around HRC50.
