High speed steel cutters, high speed steel and breathable steel properties
Performance:
1. High abrasion resistance.
2. High compressive strength.
3. High surface hardness after hardening.
4. Excellent overall hardenability.
5. Good surface treatment processing performance.
6. Excellent resistance to tempering and softening.
Breathable steel is a fine-grained, spherical, powdered stainless steel sintered at high temperatures, with tiny vents evenly spaced in all directions. It is also known as a porous material or porous metal and is used in injection molds to trap air.

Performance:
1. Reduce the injection pressure and reduce the molding and holding time.
2. Reduce and eliminate the internal stress of the molded parts, and prevent the product from deformation and warping.
3. Plastic parts with skin grain on the surface, due to the bright skin texture produced by high temperature and high pressure, can solve the problem of requiring the surface to be matte.
4. Due to the close fit of the mold parting surface, the problem of difficult mold opening can be solved. It solves many problems, thimbles, insertions, etc. Failure to provide sufficient surface area to accommodate the large amounts of gas that may be generated, avoiding defects such as flash caused by parting surfaces or other exhaust systems.

5. It can solve and alleviate the problems of gate deviation, uneven wall thickness, thin-walled products and other difficult molding.
6. It can completely solve the defects such as burns, flow marks, material shortage, and deformation of parts caused by the rapid accumulation of gas generated by high temperature of molding materials and pressure in the mold cavity.
7. Improve molding production efficiency and save production costs.
