Sand core molds often face challenges such as wear caused by high temperatures and repeated loads. By combining OX-FSP and nitriding treatment technologies, these issues can be effectively addressed. OX-FSP imparts high residual compressive stress to the surface, while nitriding further enhances surface hardness. After treatment, sand core molds demonstrate significantly improved surface roughness and durability, with their lifespan extended from 2,000 shots to over 18,000 shots. This technology delivers both high precision and extended lifespan, optimizing manufacturing efficiency.
