生产中，选择合适的压铸压力和相对应的压铸速度为优质压铸件的生产打下基础，那么压铸压力和压铸的速度，你了解多少呢？ In the production of zinc alloy die-casting , choose the appropriate die-casting pressure and corresponding die-casting speed to lay the foundation for the production of high-quality die-casting parts. Then how much do you know about the pressure and speed of die-casting?
中压射压力的作用是克服熔融金属填充路程上的阻力，生产实践证明，压射压力同所需要生产铸件的质量和生产紧密相连，锌合金压铸锁采用的压射压力一般为 20~30MPa ，但也并不是超出了这个范围就不可以采用，对于具体的压铸件，仍然是需要根据设计而定。 The role of the injection pressure in the zinc alloy die casting is to overcome the resistance on the filling path of the molten metal. Production practice has proven that the injection pressure is closely related to the quality and production of the required casting. The injection pressure used by the zinc alloy die casting lock is generally 20 ~ 30MPa , but it should not be used beyond this range. For specific die castings, it still needs to be determined by design.
生产中压铸速度包括什么呢？ What does die casting speed include in zinc alloy die casting production? Among them, there are two different concepts of injection speed and inflow speed of the gate. The injection speed refers to the speed at which the hydraulic pressure in the injection molding cylinder of the die-casting machine advances the injection punch, also known as the punch speed. It refers to the linear velocity of the molten metal when it is introduced into the cavity through the gate. The inflow speed of the gate refers to the basis of the width and thickness of the gate and the basis of the required inflow volume or the volume of the metal inflow cavity, which constitutes the area of the inflow gate. .
