Foam mould is made of high quality aluminum alloy casting forming, a scientific and reasonable design, light weight, good toughness, long service life, heating and cooling time is short, easy to operate, quick demoulding, high foam molding rate, province water vapor.

The characteristics of bubble type casting process:

1. High precision casting, lost foam casting is a nearly WuYuLiang, precise forming of new technology, the process need not take mold, parting surface and sand core, thus casting without flash, burr and draft Angle, and reduces the error caused by combination of core sizes. The casting surface roughness can reach Ra3.2 to 12.5 mu m; Casting dimension accuracy can reach CT7 to 9; Machining allowance for a maximum of 1.5 to 2 mm, can greatly reduce the cost of machining, compared with the traditional sand casting method, can be reduced by 40% to 50% of the mechanical processing.

2. The design of flexible: for casting structure design provides sufficient degrees of freedom. Casting by foam mold piece combination can be a highly complex castings.

3. So won''t appear in the traditional cast cores in traditional sand casting is not allowed because of the sand core size or the core location inaccuracy caused by uneven casting wall thickness.

4. Clean production in the sand without chemical adhesive, harmless to the environment, low temperature foam sand recovery more than 95%.

5. Reduce investment and production cost reducing the weight of the casting blank, small machining allowance.
