失蜡铸造这种方法是用熔模材料制成熔模件并组成模组，然后在模组表面涂覆多层耐火材料，待干燥固化，将模型加热溶出磨料，经过高温培烧后，浇入金属液冷凝后即得熔模铸件。

This method is used in the lost wax casting mold material and mold composition module, and module in coating multilayer refractory material, for drying and curing, the model of heating stripping abrasives, after high temperature sintering, poured into the condensed liquid metal is obtained after casting.

熔模铸造的特点：铸件尺寸精度高、表面粗糙度细，出配合面需进行机械加工外，其余部位的形位公差及表面粗糙度均不需要加工而达到设计要求。能够铸造外型复杂的铸件，能铸造异形复杂小孔及薄壁零件。可用于铸造的合金不受限制。可铸造铜、不锈钢、合金、铝等。

Investment casting features: casting size precision, surface roughness is fine, the matching surface needs machining, the remaining parts of shape and position tolerance and surface roughness do not need to be processed to meet the design requirements. It is able to cast complicated castings, and can cast special-shaped, complicated small holes and thin wall parts. Alloys that can be used for casting are not restricted. Can be cast copper, stainless steel, alloy, aluminum and so on.
