With the rapid development of science and technology and industrial production, the application scope of investment casting technology is expanding. Compared with the rapid development of investment casting industry, the performance and quantity of wax are difficult to synchronize. Therefore, various organic, plastic, carbonate and other materials have been selected. Some can be added to wax as filler, and some can be directly used to make molds instead of wax. Therefore, wax molds and waxes are gradually replaced by molds and investment molds. However, ordinary people are still used to calling them "wax models". However, this "wax model" is no longer a "wax model".

Medium temperature wax precision casting is combined with the manufacturing process of silica sol shell, while low temperature wax is generally combined with the manufacturing process of sodium silicate shell. It is characterized by small line shrinkage and simple use of equipment. The wax treatment method of hot rolling industry is different from that of medium temperature model wax treatment. Medium temperature wax is dehydrated and purified, and low temperature wax is dewaxed.

The properties of medium temperature wax are introduced as follows:

1. Since low-temperature wax contains water, the shrinkage of medium temperature wax is greater than that of low-temperature wax.

2. Its treatment methods are different, which are dehydration, purification and re treatment.

Physical properties of medium temperature wax precision casting materials: mainly rosin type and filling type, with a dissolution point of 70-100 ℃, mainly used for castings with high dimensions and high surface requirements. Wax is dewaxed by steam or microwave. The wax can be reused. It is closely combined with the shell manufacturing process, while the low-temperature wax is generally combined with the sodium silicate shell manufacturing process. Since low-temperature wax contains water, the shrinkage of medium temperature wax is greater than that of low-temperature wax. For steam or microwave dewaxing. This mold material is usually used with silica sol adhesives. It is usually formed by waxing mechanism.
