Problem & Solution

Q

Product Cracking/Cracks

A

The essence of cracking is that the internal stress exceeds the material strength limit, and it needs to be addressed from two aspects: reducing stress concentration and improving material toughness.

Extrusion & Post cooling rate demolding internal stress cracking

Q

Surface Orange Peel/Roughness

A

Surface defects are the result of the combined effects of mold condition, process parameters, and material formula, and each factor needs to be systematically investigated and optimized in a targeted manner.

Q

Surface Flow Marks/Ripples

A

Surface defects are the result of the combined effects of mold condition, process parameters, and material formula, and each factor needs to be systematically investigated and optimized in a targeted manner.

Q

Product Warpage and Deformation

A

The deformation problem stems from internal stress caused by uneven shrinkage or heating in various parts of the product, and needs to be systematically solved from three aspects: structural design, process parameters, and post-treatment.

Q

Product Shrinkage/Shrinkage Cavities

A

The core of shrinkage defects lies in the contradiction between material curing volume change and insufficient process compensation, which needs to be comprehensively controlled through formula optimization and process adjustment.

Q

Runaway Exotherm/Explosive Polymerization

A

This problem requires comprehensive analysis from multiple dimensions of materials, processes, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.

Q

Incomplete Curing of the Product/Long-Term Tackiness

A

The core of the poor curing problem is that the chemical reaction conditions are not met, and the formula ratio and curing process parameters need to be precisely controlled.

Q

Surface Bubbles/Voids on the Product

A

The essence of this problem is that gas is not effectively removed during the casting '2079851475616104453, and it needs to be solved collaboratively from three aspects: degassing process, casting method, and venting design.

Q

Product Chalking After Outdoor Use

A

In summary, the causes of the 「Product Chalking After Outdoor Use」 problem can be attributed to the combined effects of multiple factors such as poor weather resistance of the resin and no UV stabilizer added. To solve this problem, it is necessary to start from aspects such as adding UV stabiliz...
