PETG injection molded part gas-assisted molding penetration
Problem Phenomenon
In PETG gas-assisted '2079851475616104452, gas penetrates the product surface or infiltrates into thin-wall areas, producing bubbles.
Cause Analysis
Gas pressure too high or gas injection time improper, melt temperature low with large gas injection resistance, product wall thickness uneven.
Solution
Reduce the gas pressure or delay gas injection; increase the melt temperature to reduce viscosity; optimize the wall thickness design to guide the gas path.
Key Takeaway
PETG gas-assisted molding requires precise control of gas injection parameters.
