Breathable steel PM-35 uses:
PM-35 air permeable steel contains a series of ultra-fine pores inside, accounting for 20%~30% of the total volume of the steel. This special structure not only has air permeability, but also can maintain the high strength, high hardness and Corrosion resistance. Therefore, inlaying PM-35 gas-inducing steel at the appropriate position of the injection mold can solve the problem of injection molding caused by gas, making the molding process more perfect. In addition, PM-35 air-permeable steel has good mechanical properties. When using and making injection molds, the same processing methods as general mold steels can be used, such as cutting, grinding, electric discharge machining, etc.
Breathable steel properties:
1. Reduce injection pressure, reduce molding and holding time.
2. Reduce and eliminate the internal stress of the molded parts to prevent production
product deformation.
3. Plastic parts with surface texture, due to high temperature and high pressure
The bright skin texture produced can solve the surface that requires matt.
4. Due to the close fit of the parting surface of the mold, it can solve the problem of opening
Difficulty and so on. The solution is usually to use thimbles, inserts, etc.
does not provide enough surface area to accommodate the large amount of potential
Gas and many other problems, avoiding the use of parting surface or other exhaust
Flash and other defects generated by the system.
6. The gas generated due to the high temperature of the molding material and the mold cavity
Scorching, flow marks, lack of material, and air suction caused by rapid pressure accumulation
Defects such as part deformation can be fully resolved.
7. Improve molding production efficiency and save production cost.
