Stainless steel precision castings have the function of not rusting and have high density. It can be seen from its production technology that only pure stainless steel liquid is required to produce castings through a series of technologies. Precision castings introduces how to cast stainless steel precision castings.
Investment casting technology is simple. To put it simply, a molten mold is made of molten materials, and several layers of special refractory coatings are coated on it, dried and solidified to form an integral mold, and then steam and hot water are used to melt the mold from the mold and put the mold into it. In the sand box, fill dry sand molds around it, and put the molds in a baking furnace for high-temperature baking. The molds and molds
Precision casting manufacturers establish pressure difference through vacuum precision casting process. Vacuum precision casting can be divided into direct casting method and special vacuum precision casting method. Usually the mold box made by the melting process is placed in a closed room, the closed room is lowered, and the sprue is inserted into the liquid metal.
The stainless steel precision casting starts the vacuum pump to make the room a vacuum and at the same time fill with liquid metal. After the molten metal in the molding box is solidified, the sealed chamber is thrown into the atmosphere to release the vacuum, and the unsolidified liquid metal in the sprue flows into the acupuncture point again. In addition, after the filling of the mold of vacuum precision casting is completed, the mold is reversed, and the molten metal remaining in the gate provides the vacuum precision casting of the feeding tilt inversion method for the solidification of the casting. This method of precision casting manufacturers is easy to produce continuously and has high production efficiency.
Silica sol precision casting is not only suitable for casting of various types and alloys, but also the production of casting dimensional accuracy and surface quality technology is much higher than other casting methods, even if other casting methods are used, casting casting is also complicated, and the difficult process is resistant to high temperatures.
If you want to produce products with a relatively simple shape, small size, and high dimensional accuracy, you can first choose profile or use cast steel. The advantage of using steel molds is that the materials are cheap, but the disadvantage is that the molds are heavy and require certain processing tools.
