Precision casting is a casting method in modern traditional casting technology.
Precision casting is a casting method in modern traditional casting technology, which can obtain relatively accurate shapes and high casting accuracy. When designing and manufacturing products, if a better casting method is used to cast wax, the metal material obtained through a series of casting passes through sand after cleaning, higher precision finished products can be obtained. Heat treatment or cold treatment can be carried out according to the needs of the product.
The main advantages of this method then produce silica sol precision casting products anywhere, casting production of relatively wide, convenient precision used in the mode, it is also possible to consume a large amount of scrap metal and renewable resources less, the cost is relatively low, and the overall economic performance is better.
When castings have high dimensional accuracy and surface finish, the products produced by valve body manufacturers can reduce the workload of machining, save a lot of machine tools and processing time, and greatly save metal raw materials.
Low-pressure casting, die-casting, centrifugal casting and other casting methods are suitable for mass production due to the high price of equipment and molds. For small sand precision casting parts, box-free high pressure the production line of the molding machine can be divided horizontally or vertically, with high production efficiency and small footprint. For medium-sized parts, gearbox accessories can choose various box high-pressure molding machine production lines and air impact molding production lines to meet the requirements of fast and high-precision molding production lines, and can be selected cold core box, hot core box, high-efficiency core making methods such as shell cores. Using resin self-hardening, sand molding and core making, etc. Process, can be applied to medium-batch large castings..
Heavy Precision for Single Piece and Small Batch Production sand for castings, manual modeling is still an important way for manual modeling to adapt to various complex requirements and is more flexible, and does not require a lot of technical equipment. Silicate sand, methods that can be used VRH silicate sand, organic ester water glass sand, clay, drying, self-hardening resin sand and cement sand, etc.
Small precision stainless steel casting precision stainless steel casting processing, can adopt horizontal or vertical typing box-free high pressure the molding machine production line has high solid molding production efficiency and small footprint; It is suitable for medium-sized castings and various box-type high-pressure molding. Optional mechanical production line and air impact molding line to meet the requirements of fast and high-precision molding production line selection of core making method. Cold core box, hot core box, high-efficiency core making methods such as shell cores. Precision stainless steel castings meet their fluidity to a certain extent and do not form a bright standard. The general temperature is715~740 c. Stainless steel investment casting flat the ingot has high hot cracking tendency, while stainless steel investment casting temperature is relatively low, generally in680~735 c.
Precision stainless steel casting is a casting process with little or no cutting. It is an excellent casting technology and has been widely used. Precision stainless steel castings can effectively ensure the fluidity of the melt during the injection molding process. The temperature selection of precision stainless steel castings should be effectively determined according to the injection distance and process to reduce the temperature and flow rate.
