                                          Four major characteristics of precision molds



1. Wear resistance

When the plastic deformation of the blank in the concave mold of the Injection mold construction turns, it flows and rolls along the surface of the mold cavity, causing intense friction between the surface of the mold cavity and the blank, which leads to the invalidity of the abrasives due to damage. Therefore, the corrosion resistance of materials is one of the basic characteristics of MoBei.Strength is the primary factor that endangers wear resistance. In general, the higher the strength of mold parts, the lower the wear rate, and the higher the wear resistance. In addition, the wear resistance is also related to the type, total number, shape, size, and distribution of cementite in the material.Plastic Spoon Injection Molding Machine.


2. Strong ductility

The operating standards of most molds are extremely extreme, with some often bearing significant impact loads, leading to brittle fracture. To avoid sudden brittle fracture of mold parts during operation, high-precision hardware molds should have high hardness and ductility.plastic household mold.


3. Fatigue cracking characteristics

During mold work, fatigue and rupture are usually caused by the long-term action of cyclic pressure in the ring. Its types include small kinetic energy repeated impact fatigue rupture, stretching fatigue rupture, touching fatigue rupture, and bending fatigue rupture.Household Plastic Mold .



4. High temperature characteristics

When the operating temperature of the mold is high, it will reduce its strength and hardness, causing initial damage to the mold shell or causing plastic deformation, resulting in ineffectiveness. Therefore, precision hardware mold steel should have high quenching resistance reliability to ensure that the mold shell has high strength and compressive strength at ambient temperature.Plastic Spoon Machine.
