Model wax is a high - quality non - filling wax. Widely used in silicon sol process precision casting industry. Suitable for general industrial parts, aerospace parts, hardware parts, tube valve parts, needle parts, golf ball and other structures, size and specification precision requirements of wax mold production. There are two main types of automobile static electricity generation: one is chemical fiber, silk wool fabric such as carpet, seats, clothing and other friction; Second, due to the car in the process of driving, the dust in the air and body paint friction. Attention should be paid to the timely addition of new wax, so as to ensure the wax in a better state of operation, but also to extend the use of all wax on the production line.


Wax, high quality model belongs to the filling wax, yan is green, with liquid, paste or billet, wax models applied in commercial hardware parts, automotive, Marine parts, golf head and thin wall parts. It has excellent dimensional stability, strength, high surface finish, CERITA 996 c excellent performance make it widely used in various shapes and sizes of parts. Medium temperature wax with silica sol shell making technology, and low temperature wax is generally with sodium silicate shell making technology.


The shrinkage of medium - temperature wax is greater than that of low - temperature wax, because low - temperature wax contains water vapor. Medium - temperature waxes are more stable in size and more expensive than low - temperature waxes. The wax treatment of medium temperature wax is different. Medium temperature wax is dehydrated and purified while low temperature wax is the reaction treatment of saponification removal. China's precision casting industry has a considerable scale, a large number of scientific and technological achievements in the casting industry into the application field, the manufacturing level of some products even close to the international advanced level.


A batch of medium and high precision casting products also serve key fields such as automobile, aerospace, ship and energy, and provide complete sets of equipment for foreign high-end users. At present, 90% of China's precision casting wax is imported from Europe and America. Our country has most of the raw materials for the production of these products, but lacks the production technology and formula. In the world, only four enterprises in the United States, Britain and Japan have mastered the production technology and formula of high-end precision casting wax, among which one company in Britain has advanced production technology.
