Marine water glass casting

Precision casting is one of the casting, so naturally belongs to the casting industry. And casting, because it is a separate, is generally attributed to metallurgy or material forming this industry, and are not yet industry planning industry. Precision casting can be based on CNC machining technology difficult to produce heat-resistant alloy castings, such as turbojet engine blades, streamlined profiles and refrigeration chambers. But the choice of precision casting technology can not only complete the mass production, to ensure the consistency of the castings, laminated sand casting bearing seat can also prevent the residual tool marks after processing.

The so-called investment casting process, simply put, is made of fusible materials (such as wax or plastic) fusible model (hereinafter referred to as sand casting or model), in its molten precision casting parts coated with several layers of fireproof coating, dry and harden to produce the overall shell, and then change steam or hot water from the shell to melt the model, and then the shell into the sand box, filled with dry sand shape around it, the casting into the calciner, high temperature baking (If you choose a high toughness shell, the so-called investment casting process, simply put, is made of fusible materials (such as wax or plastic) fusible model (hereinafter referred to as sand casting or model), coated with several layers of fireproof paint, dry and harden to produce the overall shell, then change steam or hot water from the shell to melt the model, then the shell into the sand box, filled with dry sand shape around it, the casting into the calciner, high temperature baking. high temperature baking.
