Re: HIPS Inner liner hole/craters
Not injection mold, but thermoformin/vacuum forming process. After forming process , inner liner assembly with cabinet and then continue to Polyurethane injection (PU).
After PU injection , this hole/crater is raises.
Not sure yet, this is because of thickness material or some chemical reaction during PU Injection.
Thanks,
