Precision casting and die casting which low cost

Precision casting depends on the requirements of the material or dimensional accuracy (cast embryo is no longer processed) low-pressure casting, centrifugal casting, gravity casting, de-waxing casting, powder metallurgy silica gel ...... are known as precision casting, die-casting is also precision casting, in fact, or depending on the foundry's equipment, casting methods, management attitudes, like schools are the same is ~ School. Stainless steel casting methods generally have the following 4 kinds, 1. sand 2. resin shell mold 3. dewaxing casting 4. powder metallurgy workpiece size, price, precision as above in order. In terms of wax casting method, casting wax mold material mostly with aluminum alloy 7075, complex workpiece to pumping heart, into the heart, into the water wax.... And so on. Precision can be controlled between 0.03 ~ 0.1mm, bik thickness can be reduced is of course the best, strength in [casting] is no problem, specifically or depending on the size of the workpiece, shape, shrinkage situation and your requirements of the place.M20P1.5 threads, can be cast out, threads on both sides of the mold surface will generally be chipped or pumping heart (similar to the art of sewing line) The above is for reference only!
