压射头是压铸机生产中传递压力的关键部件，它以ZX106kN／m2的压力、100m／s左右的速度施加于液态金属，使其填充压铸模型腔。从而获得高质量的压铸件。压射头所处环境十分恶劣，使用寿命很低。国内少数厂家采用合金钢制造，其寿命也仅有六、七个班次，并且容易磨损压室．使压
The injection head is the key component of pressure transmission in the die-casting machine. It is applied to the liquid metal at a pressure of ZX106kN / m2 and a speed of about 100m / s to fill the die-casting mold cavity. To obtain high-quality die-casting. Pressure head where the environment is very poor, low life expectancy. A small number of domestic manufacturers of alloy steel, its life expectancy is only six or seven flights, and easy to wear pressure chamber. Make pressure
