Causes and solutions of bubbles in injection molding

In the process of injection molding, bubble is a very common phenomenon, light is harmless, heavy directly affects the actual quality of injection molding products.

1、 Causes of bubbles in injection molding
In the process of injection molding, when the wall thickness of the product is large, the cooling speed of the outer surface is faster than that of the central part. Therefore, with the cooling process, the resin in the central part shrinks and expands to the surface, resulting in […]

How to solve the peculiar smell of injection molding products

Injection molding products are not only required to be qualified in quality, but also have adverse effects on customers if there is a peculiar smell in the produced injection parts. In particular, some injection molding plants use qualified plastic particles, and the increase of peculiar smell will directly affect consumers’ purchase of products. Therefore, injection molding products need to be guaranteed that there is no bad smell.

1. Strictly control the use of additives
The TERT amines used in the production […]
