Technology and R&D

We have established an engineering technology materials R&D center to invest more in product development and technological innovation. In line with the CAD and UG three-dimensional mold creation capabilities equipped with independent R&D, we can reduce design defects, improve casting quality, and improve product processing and casting methods, technologies and The improvements and innovations in the process have made Shengrong a complete solution provider in the high-end casting industry that integrates R&D and production.

Casting processes

Green sand casting

Green sand molding process is mainly composed of raw sand, clay, coal powder and water. In the process of molding, sand is formed under the action of external forces and reaches a certain degree of compactness, it is able to volume-produce of castings efficiently while maintaining high-quality standards.

Investment casting

Investment casting surrounds the pattern with refractory material to make a mold, and a molten metal is cast into the mold. Due to the hardness of refractory materials used, investment casting can produce products with good surface qualities, which can reduce the need for machine processes.

The castings produced by the investment casting process have high surface precision and can adapt to various complex shapes. When customers have special requirements for dimensional accuracy, surface smoothness and part structure design of small and medium-sized parts, investment casting is the best choice

Lost-foam-casting

· SHENGRONG  provides a full range of high-quality sand casting solutions for ductile iron, gray iron, stainless steel, alloy steel and          other materials.highly flexible production facilities of lost foam casting allow us to produce casting volumes from prototype to                20,000   tons per year

· Our castings range from 1 kg to 1,000 kg, Maximum size of the flask is 1100 x 1100 x 1000 . We run two molding and pouring lines.

Lost foam casting

Lost foam casting is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax.

This casting process is advantageous for very complex castings that would regularly require cores. It is also dimensionally accurate, maintains an excellent surface finish, requires no draft, and has no parting lines so no flash is formed.

No-bake-resin-sand-casting

· SHENGRONG provides a full range of high-quality sand casting solutions for ductile iron, gray iron, stainless steel, alloy steel and            other materials. 

· SHENGRONG consists of two production molding areas, providing flexible and high capacity production. piece weight from 5 kg to        10,000 kg, produces casting volumes from prototype to 20,000 tons per year.

No-bake resin sand molding

No-brake resin sand molding is a sand molding process where synthetic liquid resin is mixed with the sand, and the mixture hardens and cools at room temperature. The casting is formed by pouring liquid metal into the resulting mold cavity after the sand mixture is fully cured and the mold halves are assembled together. This process takes place in a normal atmosphere without adding heat to the mold prior to the pour.
