6.0Mpa Low Thermal Expansion Precoated Resin Sand

High Quality Making Mold Core Precoated Resin Sand with Low Thermal Expansion

Description of precoated resin sand :

Precoated resin sand uses high-quality natural quartz sand as raw sand, thermoplastic phenolic resin, methenamine and enhancers as raw materials.

Depending on the technology needs of users, the curing speed, stripping, flowability, collapsibility, the casting surface finish, storage of silica resin coated sand can be adjusted and matched appropriately.
silica resin coated sand is one of the best moulding sand for cars, tractors and hydraulic parts.

Products Specifications

Features :

1. Vibration sand cleaning, high strength, low gas, low expansion;
2. Lax, good casting surface finish;
3. Burly mould shell surface, good thermal stability, good thermal conductivity, good liquidity, smooth casting surface;
4. High strength, high temperature, less expansion, good mold release, no sand sticky;
5. Uniform shell layer, fast curing;

Application :

Resin coated sand is a non-quartz artificial sand employed to the production of metal casting.

silica resin coated sand also can be used for many casting methods such as vacuum casting, VRH, LFC, investment casting, common and resin sand. The fused ceramic foundry sand can be with many adhesives, greatly improving the quality of castings.

1. Production of low pollution coated sand, reduce the use amount of resin and curing temperature; improve coated sand's overall performance, especially in high temperatures; research and develop of pollution-free phenolic resin alternatives.

2. Improve the regenerative capacity of coated sand.

Our mine company established in 2003,and its trade company ,Qingdao Jinjunxuan International Trade Co.,Ltd,founded in 2018, relying on the group's logistics advantages and rubber trade experience, Jinjunxuan international has been shouldering the responsibility of group logistics business development and model transformation since its establishment.

In 2019, In view of the fierce competition in the raw material market, we pay more attention to the quality of products and firmly believe in the concept of "quality-oriented, honest operation". We also rely on mine company technical advantage to develop customized products.

Using our product, the casting is easy to be shelled, not deformed, not easy to shrink, with good finish and high yield. After that, remind the customer not to be greedy for cheap choice of cheap sand so as not to affect the casting finished products.

It is recommended to choose the products of regular mullite manufacturers with reasonable price, quality and more guarantee. We hope that through our efforts and careful service, we can provide customers with cost-effective products and contribute to the development of the investment casting industry.
