Which cost is lower, precision casting or die casting?

Precision casting depends on the accuracy of materials or dimensions (no further processing after blank casting). Low-pressure casting, centrifugal casting, gravity casting, dewaxing casting and powder metallurgy silica gel are all called precision casting. Die casting is also precision casting, but it still depends on the equipment, casting method and management attitude of the foundry, just like schools. Generally, there are four kinds of stainless steel casting methods: 1. Turning sand; 2. Resin shell mold; 3. Wax casting; 4. The size, price and accuracy of powder metallurgy workpieces are arranged in this order. In the case of dewaxing casting, most of the die materials for wax casting are aluminum alloy 775, and complex workpieces are cored, cored and watered. The accuracy can be controlled between .3 and .1 mm, and it is of course best to reduce the thickness of the wall. The strength is no problem [in casting], depending on the size, shape, shrinkage and your requirements. The thread of M2P1.5 can be cast, and both sides of the parting surface of the thread are generally flattened or cored (similar to art stitches) for reference only! []
