压铸型的结构和制造工艺较为复杂.因而其制造成本较高。压铸型的寿命除了与压铸型的结构设计、模具材料及后处理方法等因素有关外,还有一个主要的因素,就是压铸型的温度控制。结合国外压铸型的先进技术,介绍了匝铸型温度的恒温保护方法。 Die-casting structure and manufacturing process is more complex, so its higher manufacturing costs. Die-casting life in addition to die-casting structure design, mold materials and post-processing methods and other factors, there is a major factor is the temperature control die-casting. Combined with the advanced technology of the foreign die-casting type, the method of constant temperature protection for the temperature of the casting mold is introduced.
