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.
By the way, there is another important
point of UPVC pipe fitting mold: you cannot use hot runner for UPVC pipe
fitting molding, during the heating process, there is HCI generate , acids will
eat into the metal. So usually we will suggest for cold runner.
