V method, lost foam casting

The use of molten ceramic sand (jewel sand) instead of silica sand can greatly reduce the dust emitted, and the silica dust contained in the dust is very small, which is of great significance to improve working conditions and protect the environment.

Alkaline phenolic resin sand application

The strength of alkaline phenolic resin self-hardening sand increases with the increase of resin content, but its strength increases slowly to a certain amount. The increase of resin dosage will not only increase the production cost, but also increase the residual alkali in the resin sand and the carbonaceous coating layer on the surface of the sand, which will affect the quality and strength of the recycled sand and the regeneration rate of the old sand.

Furan resin sand application

Due to the good collapsibility, strong regeneration and high recovery rate of fused ceramic sand (treasure sand) furan resin, compared with the traditional sodium silicate sand process or silica sand furan resin process, the waste sand discharge is small and the regeneration equipment is simple. Only a simple secondary mechanical friction regeneration can achieve a high regeneration rate, which can not only produce high-quality castings, but also has significant comprehensive benefits.

Application of Stainless Steel Castings

The processing of process details of stainless steel castings directly affects the quality of stainless steel castings. Sand is still a very important auxiliary material for stainless steel precision castings. Stainless steel castings also have certain requirements for the selection and use of sand, and must meet the requirements to ensure that the effect of casting treatment reaches the standard. The key part of the production of stainless steel castings is the sand treatment part, as the name implies is to deal with dry sand, the choice of this sand itself is less dust, the effect will naturally be good, especially the jewel sand.
