LIHE MOLD BLOG

In plastic mold processing, the quality of the mold determines production efficiency. When selecting mold materials, we should do the following: Abrasion resistance, Strength and toughness, Fatigue fracture property, High-temperature performance, Cold and hot fatigue resistance and Corrosion resistance.

The mold temperature depends on the crystallinity of the plastic, the size and structure of the product, the performance requirements, and other process conditions (melt temperature, injection speed, injection pressure, molding cycle, etc.).
