Products

Parameters:

Brief introduction:

As a typical representative of non-crystalline materials, PVC plastic has poor fluidity and is easily decomposed. Stabilizers, calcium carbonate, etc. are often added as fillers in products, which are abrasive to the barrel screws. During the molding process, some PVC resins will release acidic corrosive gas, so the plasticized parts used for molding must have certain corrosion resistance.

Basic parameters:

Scope of application:

Building materials (plastic pipe fittings)

Medical industry

Toy

Shoe materials, product packaging and other fields

Composition and process:

The low-shear structure prevents excessive heat concentration and further excessive shearing during the pre-molding process, effectively preventing product black streaks.

The use of fully automatic plasma surfacing and ion-nitriding electroplating technology has greatly improved the corrosion resistance and wear resistance
