Gas penetration in PCTG gas-assisted molding
Problem Phenomenon
In gas-assisted '2079851475616104452, gas penetrates thin walls of the product or forms bubbles on the surface.
Cause Analysis
Gas pressure too high or injection timing improper, melt viscosity too low.
Solution
Reduce gas pressure; optimize gas injection timing; appropriately increase melt viscosity.
Key Takeaway
PCTG gas assist requires precise control of gas injection parameters.
