Application of breathable steel in injection molds
Breathable steel is a kind of fine-grained powder stainless steel fired at high temperatures, it is also called porous metal, which can be used in injection molds with air trapping problems.
Properties of breathable steel
For injection molds with air trapping problems, inserting breathable steel in the corresponding position can effectively solve the problem and ensure product quality. The processing performance of breathable steel is the same as that of standard mold steel, such as cutting, grinding, and EDM processing.
The properties of breathable steel are as follows:
1. Small specific weight, high specific strength. 2. Large specific surface area. 3. Good vibration control effect. 4. Good energy absorption.
Function characteristics
Lower injection pressure and reduce molding and holding time during the injection molding process.
Reduce and eliminate the internal stress of the product, prevent the deformation and warpage of the product.
Defects such as short shots, flow marks due to the gas of high temperature of raw material, and rapid gathering pressure in the cavity can be fully solved.
Difficult molding issues such as uneven wall thickness can be solved
Improve product efficiency and save production costs.
