Key Factors Improving Mold Life time.

1.PVD coating for Mold surface.

TiN, TiCN and other coatings are plated on the surface of the Mold to improve the wear resistance and corrosion resistance.

2.Reasonable Mold structure design

ensure that the Mold in the work of uniform force, not easy to partial load, stress concentration is small. Reasonable structural design can ensure the strength, stiffness, concentricity, neutrality and reasonable blanking clearance ‌‌

3, Use harden material like H13, S136, Beryllium cooper.

Now, I’ll introduce Becu as example.

Beryllium copper is known for its exceptional hardness, which allows it to withstand the high pressures and forces encountered during the injection Molding process, so it’ll with higher wear Resistance that can help increase Mold life.

The thermal conductivity of beryllium copper is 3-4 times higher than that of steel, facilitating rapid heat dissipation from the Molded plastic.

Meanwhile, Beryllium copper exhibits remarkable resistance to thermal stress, which is critical in maintaining structural integrity under varying temperature conditions. This characteristic minimizes the risk of cracking or deformation that can occur with other materials, thereby enhancing Mold longevity.

In summary, beryllium copper improves the lifespan of injection Molds through its hardness, thermal conductivity, machinability, and resistance to thermal stress. These attributes lead to enhanced durability and efficiency in the Molding process, making beryllium copper a preferred choice for high-performance injection molds across various applications.
