Features of lost foam (EPC) casting
1.The dimensional accuracy of the castings is high, and the dimensional accuracy and surface roughness of the castings depend mainly on the appearance of the foam. After the shape is made, it can not mold, no core, no parting surface, no casting inclination and live block, reduce the dimensional error caused by the core block combination and the flash burr caused by the box 2, and the surface quality is achieved ( Ra 8-10um) is close to investment casting.
2.The degree of freedom in designing the casting is increased, and since the foamed plastic pattern is extremely easy to be vaporized, there is no parting surface, and there is no mold release and lower core. In some complex shape castings, the problem that is difficult to achieve in ordinary sand casting is not at all difficult in EPC casting, so it provides sufficient free space for the gradual design of complex structures.
3.It simplifies the production process of castings, shortens the production cycle, and improves labor productivity compared with ordinary sand molds, non-collision type, mold release, no repair, no core and box. The EPC method can cast a variety of shape castings in one box. The production cycle depends on the time of smelting molten steel, while reducing the labor intensity, changing the working conditions, facilitating internship cleaning production and automated production, and improving productivity.
4.Reduce material consumption and reduce production costs. The cost of ordinary steel castings, sand and adhesives, and manual molding is very high, while EPC sand consumption is between 2-4%. Dry sand reuse saves a lot of labor. EPC process It can reduce the cost of castings by 15-30%, and has obvious economic benefits.
