Stainless steel precision sus 304 casting using a wax mold → do sand mold → liquid material filling process. Can be made according to different wax models of changing products.
1, according to different shapes of products to do mold. Mold points up and down die mode, through the car, planing, milling, etching, EDM and other integrated processes to complete. The shape of the pit is the same as that of the product. Because the wax mold is mainly used for industrial wax pressure type, so the choice of melting point is not high, the hardness is not high, lower requirements, cheaper prices, lighter weight aluminum alloy mold.
2, the use of aluminum mold to produce a large number of industrial wax solid core model. Under normal circumstances an industrial wax solid core model can only correspond to a rough product.
3, the wax mold around the amount of refinement, to the burr after a number of single wax mold (also known as group tree) prepared in advance of the die, the die is also produced by wax mold industrial wax Core model.
4, will have been fixed in the die on a number of wax mold coated with industrial glue evenly spray the upper layer of fine sand (a refractory sand, high temperature, usually with the silicon sand). The sand particles are small, very fine, so as to ensure that the final blank surface as smooth as possible.
5, at the set room temperature (or temperature) under the spray layer of fine sand wax mold naturally dry, but can not affect the shape of the internal wax mold changes, the natural drying time depends on the complexity of the product itself, the general casting Of the dry time about 5-8 hours or so.
6, sub-sand spray and natural air-dried, in the wax mold surface to continue on the industrial glue (silicon slurry), and sprayed on the second layer of sand, the second layer of sand particles than the size of the sand before the large, To the rough Spray the second layer of sand is also set at constant temperature so that the wax mold naturally dry.
