What are the characteristics of precision injection processing molds

Nowadays, the requirements of plastic products are getting higher and higher, which has resulted in precision injection molding processing technology. Today, the editor of Huanke Mold Development will introduce the characteristics of precision injection molding molds.

精密注塑加工模具的特点有哪些

1.Abrasion resistance

When the blank is plastically deformed in the mold cavity, it moves and slides along the outside of the cavity, causing fierce friction between the outside of the cavity and the blank, which causes the mold to take effect due to wear. Therefore, the abrasion resistance of the material is one of the most fundamental and important functions of the mold. Hardness is an important factor affecting wear resistance. As usual, the higher the hardness of the mold, the smaller the amount of wear, and the better the wear resistance. In addition, abrasion resistance has nothing to do with the type, number, state, size, and spread of carbides in the guess.

2.Toughness

The premise of the mold is mostly very tenacious, and some are often subjected to a large blow load, which leads to brittle fracture. In order to avoid the mold machine from being suddenly brittle at the time, the precision metal mold must have high strength and toughness. The toughness of the mold depends on the carbon content, grain size and structure of the material-precision mold manufacturing.

3.Tired and broken function

In the process of the mold, under the long-term influence of recurrent stress, fatigue and breakage are often caused. The situation has small energy repeatedly hitting fatigue fractures, stretching fatigue fractures, fighting fatigue fractures, and twisting fatigue fractures. The fatigue fracture function of the mold depends on its strength, toughness, hardness, and the content of inclusions in the material.

4, low temperature function

When the temperature of the mold is higher, the hardness and strength will be reduced, which will cause the mold to wear later or plastic deformation to take effect. Therefore, the precision injection mold should have higher resistance to tempering, and the tube mold should have higher hardness and strength at the working temperature.
