Features:1, precision casting, casting dimension precision, surface roughness, the dimension precision of casting can reach level 4, 6, the surface roughness of 0.4-3.2 mu m, can greatly reduce the casting machining allowance, and can realize WuYuLiang manufacture, reduce the production cost.2, casting shape is complex, and difficult to use other method processing of castings. The casting dimensions to a few millimeters to thousands of small mm, thickness 0.5 mm, the thinnest below the holes by 1.0 mm.Unlimited: 3, alloy material such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy and high temperature alloy, titanium alloy precision casting production and precious metals and other materials are available. For forging, welding and cutting hard alloy materials, especially for the methods of the precision production.4, high flexibility, strong adaptability. Both can be used in mass production, also applicable for small batch and single production.
