 Feature:      
1. The original high sand content of the SiO, granularity division is reasonable, can effectively prevent the adhering sand.
2. Steel, special steel can be used to replace zircon sand of quartz the sand.
 3. To select the shape, phase change process, activation treatment can greatly improve the strength of the coated sand
 4. To reduce the dosage of resin and curing agent, effectively improve the strength of cold and hot composite resin, avoid subcutaneous blowhole
  5. Composite curing agent to make coated sand in core, pouring process does not produce ammonia, improve the working environment

Cast steel is a kind of excellent high temperature performance of precoated sand and casting performance of new products of precoated sand, cast steel with high strength of precoated sand, good liquidity, curing speed, more content of SiO2, strong resistance to high temperature, low gas evolution, liquidity is good wait for a characteristic, is a widely used in joint valve shell, buffer, steel shaft, the modelling of engineering excavators, such as pieces of container Angle steel material.

Mainly adopts the high quality of precoated sand selected natural quartz sand as the original sand, thermoplastic phenolic resin, methenamine and strengthening agent as raw materials.

 According to the different technical requirements of users, the curing speed, membranous, liquidity, melting, casting surface roughness ratio of appropriate adjustments, storage, etc. Are cars, tractors, hydraulic parts, etc. One of the best molding materials.
