PC Injection Machine Screw Wear Acceleration
Problem Phenomenon
After processing glass fiber reinforced PC, the screw and check ring wear quickly, and metering fluctuates.
Cause Analysis
Glass fiber strongly wears metal, and ordinary nitrided screws have a short service life; after wear, plasticizing and metering become unstable, and product quality fluctuates.
Solution
①Use bimetallic/hardened screws and barrels for GF-PC; ②Regularly check the check ring clearance; ③Monitor the trend of plasticizing time changes.
Key Takeaway
Glass fiber material must be equipped with a wear-resistant plasticizing system.
