Coated sand casting production line: efficient and environmentally friendly casting solution - Ruihai Changrun leads the industry innovation

2025-03-27

1. What is coated sand casting?


Coated sand casting is a high-precision casting process that uses resin as a binder and is formed by high-temperature curing. Its core material "coated sand" is a phenolic resin evenly coated on the surface of quartz sand. After thermal curing, it forms a high-strength sand mold. It is suitable for the production of metal castings with complex structures and high surface finish requirements. It is widely used in automobiles, machinery, aerospace and other fields.


2. The core advantages of coated sand casting production line

High precision and surface quality

Coated sand castings have good dimensional stability and can produce castings with thinner walls and more complex details. The surface roughness can reach Ra 6.3~12.5μm, reducing subsequent processing costs.


High production efficiency

The automated coated sand production line can achieve rapid core making and molding, with a short curing time (usually only a few tens of seconds), suitable for mass production, and significantly improves production capacity.


High material utilization rate

Coated sand can be recycled and reused (the recovery rate can reach more than 90%), and the intelligent system controls the sand-iron ratio, which greatly reduces the waste of raw materials.


Environmental protection and energy saving

Modern coated sand technology uses low-ammonia and low-odor resins, combined with tail gas treatment equipment, to reduce pollution emissions during the production process, in line with green manufacturing standards.


Strong adaptability

It can produce castings of various materials such as cast iron, cast steel, and aluminum alloy, especially suitable for precision parts such as turbine housings and engine cylinder heads.


3. Ruihai Changrun: Practitioner of coated sand casting technology

As a professional company with a mature coated sand production line, Ruihai Changrun is committed to providing customers with full-process services from mold design, sand core production to casting molding. The company introduces intelligent equipment and process management systems to ensure product consistency. At the same time, the technical team continuously optimizes the formula and process to help customers solve the problem of yield rate of complex castings.


"We not only provide coated sand castings, but also provide efficient and sustainable casting solutions." Ruihai Changrun's technical director said that in the future, the company will further integrate the Internet of Things and digital technology to promote the development of the foundry industry towards intelligence and low carbonization.


4. Conclusion
