Vacuum casting technology is commonly used in the manufacturing industry for rapid mold production, for silicone molds, polyurethane molds and small batch injection molded parts.
In recent years, along with the use and popularization of rapid prototyping technology, more and more vacuum casting companies are feeling the economic benefits provided by this technology in the process of product development and design. Unbeknownst to them, the widespread use of this technology and the expansion of its applications have increased the demand of small and medium-sized companies for small and large production runs and mold making (already in prototype form).
Using vacuum casting technology, it is possible to make small batch parts or simple molds directly from rubber products. At present, there are hundreds of rapid prototyping machines and five business systems in China, and the production efficiency of each province and city is also promoting the rapid prototyping technology and rapid mold making technology, and there are also a number of companies with rapid prototyping technology and equipment open to the public to carry out rapid prototyping technology and rapid mold service projects, so the use of this technology and market demand for sales market is very large.
Vacuum casting technology can be generally applied to product development and small and large production in the fields of vehicles, household appliances, light industry, YL, agricultural machinery and so on.
Rapid mold production and manufacturing use is very common, the development trend is also very fast. The efficacy of the new product development link in the city square and some places where the surface look is obtained according to the compound type is remarkable. The basic principle of vacuum pump casting molding is to pour silicone and rubber products into the mold frame or mold under the condition of vacuum pump, and the raw materials are pumped out of the vapor bubble under the action of negative pressure force, so that the forming raw materials are firmly affixed to the original shape or mold surface dry solid, and then ensure that the mold or part casting molding has high precision of compound shape.
Epoxy resin vacuum casting process and characteristics
Epoxy resin vacuum casting means that under the standard of vacuum environment, the epoxy resin, epoxy curing agent, multi-functional modifier and organic powder equipment filler and other secret raw materials are poured into the set mold parts, after the dry solid reflection by thermosetting liquid chemical cross-linking, the whole process of getting thermosetting plastic products out of the mold.
Epoxy resin vacuum casting technology belongs to the dry test overall insulation layer management system, is nowadays the core insulation layer encapsulation form technology in the field of electric welder. Its processing technology is used for the insulating layer encapsulation form of electronic devices, household appliances, electric welders and other commodities. According to the different structure of the insulating layer of commodities and the secret recipe of casting material, it can be classified as: casting, wrapping, gluing and its automatic working pressure suspect glue (APG) processing technology and other forming processing technology.
Epoxy resin vacuum casting system software machine equipment is more suitable for medium and small transformers, high-voltage and low-voltage voltage transformer and Kor-voltage insulation layer parts of the closed full vacuum casting processing technology. Its advantages are good environmental protection and energy saving, easy to use, convenient maintenance, low cost operation, and its semi-closed type of seasoning processing process can effectively improve the working environment and reduce labor efficiency. The epoxy resin casting products produced by the application of this system software machinery and equipment have good impact toughness and reliable electrical insulation performance.

Why does casting use draft?
Draft angles are the amount of taper inserted into the die cast tool's side walls and cores to help remove a part. Their main purpose is to lessen friction as the part is expelled from the tool. Parts can be stripped, damaged, or become caught in the tool if there are no draft angles.
In a vacuum, is pressure 0?
There are no gas molecules in a vacuum. No molecules means no pressure. A bell jar can have a lot of gas particles removed from it using a vacuum pump.
