Product features and applications
Material selection advantages: We offer a diverse range of material selection options based on different sintering processes and product requirements. High-speed steel molds are suitable for medium-low cost production, while carbide molds are suitable for high-precision and high-volume production. And high-temperature alloy molds are specifically used for ultra-high temperature ceramic sintering processes. Each material has undergone strict heat treatment optimization to ensure its mechanical properties and heat resistance reach the optimal state.
The high-temperature resistant sintered molds are made of special materials and undergo heat treatment processes, enabling them to operate stably at temperatures ranging from 1200 to 1600 degrees Celsius, while maintaining unchanged shape and dimensional accuracy. The thermal expansion coefficient of the molds has been precisely calculated and compensated to ensure that the dimensional accuracy under high temperatures meets the production requirements.
Precision Control: We employ a high-precision CNC machining center in conjunction with a three-coordinate measuring instrument to ensure that the size accuracy of the mold cavity is controlled within ±0.02mm, and the surface roughness can reach Ra 0.4μm or below. The mold structure design takes into account the compensation for material thermal expansion to ensure high precision compatibility even at working temperatures.
The service life of our molds varies depending on the different application materials and working conditions, ranging from 5,000 to 50,000 times. By optimizing material selection, structural design and surface treatment processes, we have effectively extended the service life of the molds and reduced the overall production costs for our customers.
