Mold composition

In addition to the mold itself, the mold base, mold base, and mold core lead to parts ejection device are also required. These parts are generally made into universal type. Mold enterprises need to be bigger and better, and determine product positioning and market positioning according to market demand, technology, capital, equipment and other conditions. These practices are especially worth learning and learning from small mold enterprises, and focus on gradually forming their own technological and product advantages. Therefore, China's mold enterprises need to actively learn from the experience of these advanced enterprises in order to develop in the future.

The important factors of die price and material are thermal strength and thermal stability. Common materials Die materials: working temperature Forming materials Die materials
