Features and advantages of stainless steel precision castings
Stainless steel precision casting is a casting method r […]
Stainless steel precision casting is a casting method relative to conventional casting processes that achieves relatively accurate shape and high casting accuracy.
1. The casting has high dimensional accuracy, fine surface roughness value, the dimensional accuracy of the casting can reach 4-6, the surface roughness can reach 0.4-3.2μm, which can greatly reduce the machining allowance of the casting; the casting shape is complex and difficult to Castings processed by other methods. The casting profile size is as small as a few millimeters to thousands of millimeters, the wall thickness is 0.5 mm thinner, and the smaller holes are 1.0 mm or less.
2. High production flexibility and adaptability. It can be used for large-volume production as well as for small batches or even single-piece production; alloy materials are not limited: such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy and high-temperature alloy, titanium alloy and precious metal. Casting production is especially suitable for the production of alloy materials that are difficult to forge, weld and cut.
Although the above several measures have greatly reduced the shrinkage and shrinkage in the thin-walled investment stainless steel precision castings, but due to different production environments and different production equipment, the causes of shrinkage porosity defects are different, so the specific problem is Specific analysis, the right medicine, can not be generalized.
