The boron nitride rods are made of boron nitride ceramics and are processed through the following series of steps: forming, grouting, grouting, drying, extrusion, cold, static pressure, hot pressing, hot isostatic pressing. They have excellent resistance to falling, abrasion, super strong, super hard, high temperature (refractory), super corrosion resistance, never rust, oxidation resistance and insulation performance. The reasonable combination of bending strength and elasticity gives the ceramic rods a high impact strength. Boron nitride ceramic rods are easy to maintain and require no paint or protective finish on the surface and cutting edges. Different shapes, sizes and precision products require different forming methods during the molding of boron nitride ceramic rods. Injection Molding Process: purchase airflow powder → with chemical components → stir evenly → dry → break → injection molding → Discharge → Sintering → Post-processing Inject
