Hydraulic die head

The hydraulic screen changer die head is made of alloy steel through forging, milling, grinding, drilling and wire cutting processing, multi-stage quenching and tempering, and nitriding hardening treatment. It has the characteristics of high hardness and ultra hard material, ensuring long-term reliable operation under high clamping force and friction sliding conditions without material leakage. The screen changer is designed with an efficient built-in core rod heating, driven by a high-speed high-pressure oil cylinder through the screen changer, and provided with driving force by a large flow hydraulic station. It has the outstanding advantages of easy and automatic screen changing, and can effectively meet the granulation requirements of safety, speed, labor saving, and non-stop screen changing. The hydraulic screen changer has a simple structure, simple maintenance, and low failure rate. It is currently a popular advanced non-stop filter in the plastic recycling industry. Network changer.
