Problem & Solution

Q

Sticky surface (incomplete curing)

A

The core of poor curing problems is that chemical reaction conditions do not meet requirements; formulation ratios and curing process parameters need to be precisely controlled.

Q

Warpage deformation

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.

Q

Surface blistering/bulging

A

Surface defects are the result of the combined action of mold condition, process parameters, and material formulation; each factor must be systematically investigated and targeted optimization performed.
