壳模铸造是精密铸造的一种,是现代机器制造工业中一种先进的铸造方法.简单的讲,壳模铸造就是把金属液浇到用人造树脂作为粘结剂的壳型中.壳模铸造是由失腊踌造演变而来的,所谓失腊铸造就是在腊模上涂挂几层含粘结剂的耐火材料,经晾干或硬化反应以后得到一个硬壳,埋于湿砂或干砂中进行造型,然后加热熔掉腊膜,构成型腔,再经过高温灼烧,驱除水分和可燃性物质后,即可以进行浇注.因此可见,在失腊铸 Shell casting is a kind of precision casting, which is an advanced casting method in the modern machinery manufacturing industry. In brief, shell casting is to pour the metal liquid into the shell type with artificial resin as the binder. Foundry is caused by the loss of wax hesitation evolved, the so-called Lost wax casting wax coating is coated with a few layers of binder-containing refractories, after drying or hardening reaction to get a hard shell, buried in wet sand or Dry sand in the shape, and then melt the wax melt, forming the cavity, and then after high-temperature burning, get rid of water and flammable substances, which can be poured.Thus, in the wax casting
