In mold manufacturing, the stainless steel precision casting molding link is in a key position. China and many countries in the world often use precision casting methods in the production process, including gypsum casting, ceramic casting, investment casting, lost foam casting, thermosetting resin casting sand mold casting, coating transfer precision casting. Coating transfer precision casting technology is a casting method that uses the coating transfer method to cover a uniform coating on the casting, which can greatly improve the dimensional accuracy of the casting and reduce the surface roughness of the casting. Compared with investment casting technology, this method is less prone to dimensional deviation; The dimensional accuracy of castings produced by this method is much higher than that of ceramic castings, and the castings are relatively easy to clean.
The mold material must have a smaller linear shrinkage and the smallest expansion coefficient at softening temperature in order to achieve the dimensional accuracy of the mold material. With small heat capacity and moderate melting point, it is convenient to pass through the wax to make the mold shell and take out the wax from the mold shell. The mold should have sufficient hardness and strength at room temperature and high thermal stability at slightly higher temperature. In order to avoid various fractures, damages or surface scratches in actual production and life.
Stainless steel precision casting has certain dimensional accuracy, small machining allowance, saving processing time and metal materials. It can be used to cast superalloy castings, such as jet engine blades, streamline profiles and cooling chambers, which are difficult to be formed by machining technology.
Alastin uses silica sol process precision casting to complete one great product after another. In addition to yacht hardware, alastin can also be applied to high standard industries such as medical treatment and construction.
