Ruihai Changrun Technology Co., Ltd.: Leading the innovation of casting materials and promoting green intelligent manufacturing
2025-02-18
In recent years, with the rapid development of industrial manufacturing technology, the foundry industry, as an important foundation of the manufacturing industry, has also been constantly seeking innovative breakthroughs in materials and processes. Among the many casting materials, clay sand, coated sand and resin sand have become indispensable key materials in casting production due to their unique performance advantages. As an industry-leading supplier of casting materials, Ruihai Changrun Technology Co., Ltd. is providing efficient and environmentally friendly solutions to the global foundry industry with its outstanding technical strength and innovation capabilities.
The "three horses" of casting materials: clay sand, coated sand, resin sand
1. Clay sand: the cornerstone of traditional technology
Clay sand is one of the most commonly used modeling materials in the foundry industry, mainly a mixture of natural sand, clay and water. Its advantages are low cost, strong reusability, and suitable for mass production. However, the traditional clay sand process also has some limitations, such as low sand mold strength and easy to produce pores and other defects. To this end, Ruihai Changrun Technology Co., Ltd. has significantly improved the strength and stability of the sand mold by optimizing the clay sand formula and process, while reducing waste sand emissions, helping enterprises achieve green production.
2. Coated sand: the first choice for precision casting
Coated sand is a casting material made by covering the surface of quartz sand with a layer of resin film. It has high strength, high precision and good disintegration. It is widely used in the production of precision castings such as automotive parts and engineering machinery. Ruihai Changrun Technology Co., Ltd.'s coated sand products not only have excellent high temperature resistance, but also can effectively reduce the sand sticking defects on the surface of castings, providing customers with cost-effective solutions.
3. Resin sand: the benchmark for high-end casting
Resin sand is a casting material with synthetic resin as a binder. It has high strength, high precision and good surface finish, and is particularly suitable for the production of complex castings. Ruihai Changrun Technology Co., Ltd. has not only improved the finished product rate of castings through its independently developed high-performance resin sand, but also greatly reduced energy consumption and pollution in the production process, providing strong support for the high-end manufacturing industry.
Ruihai Changrun Technology Co., Ltd. is writing a new chapter in the industry with innovation and ingenuity. Whether it is clay sand, coated sand or resin sand, Ruihai Changrun Technology will create greater value for customers with excellent quality and service, and safeguard the green future of the foundry industry.
