Three Injection Molding Temperatures
Original: Original | Author: DGMF Mold Clamps | Publish Time: 2021-07-17 | 2733 Views | Share:
Today we talk about the three main injection molding temperatures and their settings.

2. Mold temperature in the injection molding temperature

The mold temperature directly affects the product size. Generally, it is set according to the material category at the trial stage, and slightly adjusted according to the product quality. It is better not to consider the change in mass production.

When the mold temperature is high, the melt fluidity is better, which is conducive to molding, but the shrinkage of the product increases, and the size will be correspondingly smaller.

When the mold temperature is low, the melt fluidity is poor, which is not conducive to molding, but the shrinkage of the product is reduced, and the size is correspondingly larger.

The mold temperature not only affects the product size but also determines the degree of crystallinity. When the mold temperature is high, the crystallinity is greater, and when the mold temperature is low, the crystallinity is small.

The mold temperature also has a certain influence on the strength of the product. When the mold temperature is low, the product strength is also low. When the mold temperature is low, the fluidity of the product becomes poor, then the position fusion of the bonding line will be affected, and the bonding line will obviously reduce the strength. , When the mold temperature is low, its crystallinity is low, and its strength is correspondingly low.
