Problem & Solution

Q

Improper raw material temperature (foaming power affected by temperature)

A

Temperature control is a key parameter of the foam '2079851475616104453; it is necessary to ensure that the temperature is accurate, uniform, and stable to guarantee product quality consistency.

Q

Product warpage

A

Deformation problems originate from internal stress caused by uneven shrinkage or heating in various parts of the product, and need to be systematically solved from three aspects: structural design, process parameters, and post-treatment.
