Product Name: Screw Barrel for High glass fibre filling PA
Description:
With the high strength & multiple appliance, High Glass Fibre filling PA material is used in a lot of areas in nowadays.
Along with its high strength, this kind of material is also comparingly much difficult to process, the glass fibre filling will cause much abrasion & demage to the screw, which makes the normal material not suitable for running this kind of PA material.
After years' test, we have now developed to use high quality alloy steel to suit with the glass fibre abrasion, which can enlength the lifespan of screw much longer.
Advantage:
1. With our unique material & treatment, we can offer screw barrel suitable for running PA with<60% Glass Fibre filler.
2. Much longer using time can achieve
3. More precise product injection
