In mold making, polycrystalline materials are usually mixed with other auxiliary materials and sintered under high pressure and high temperature. Since polycrystalline molds have high hardness and toughness, they are widely used in high-speed processing and precision molds.

For this reason, we propose a high-strength and wear-resistant polycrystal mold laser processing device. Utility Model Content
