Causes and solutions of whitening in injection molding products

The reason for the whitening of injection molding products may be that the force is not correct when demoulding leading to poor demoulding, and the release pin exerts too much force on injection molding products, resulting in whitening. Or the load is too large, white injection products as long as a little force will produce cracks.

Mold injection molding products produce whitening solutions

1. Reduce injection pressure; 2. Improve the finish of injection model cavity; 3. The product should have enough release inclination, and the release pin should be balanced.

Notes on whitening of injection molding products

1. The fusion marks generated by injection molding products due to release agents are easy to separate, which must be avoided; 2 to distinguish the fusion marks and cracks, just on the product coated with ink can be quickly distinguished; 3. Attention should be paid to the whitening phenomenon of ABS plastics in post-processing; 4. It is easy to appear defects such as flying edge in the place of melting traces.

Due to the difference of materials, ABS is prone to whitening, and plastic materials with poor fluidity are prone to produce fusion marks and other defects in the process of injection molding. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the service life is long, the mass production is fast and the finished product quality is excellent!
