Resin Coated Sand Casting – Leesh Global Sand Casting Leader

Leesh: Your Premier Resin Coated Sand Casting Partner

Leesh – Sand Casting Foundry is at the vanguard of the sand casting industry, renowned as a leading supplier in the global arena. Our proficiency in resin coated sand casting sets us apart.

Key Processes in Resin Coated Sand Casting

Shell Molding

Shell molding is a cornerstone of our resin coated sand casting operations. By applying a resin – coated sand mixture around a heated pattern, we create a thin, hardened shell. This shell offers exceptional dimensional accuracy, making it perfect for intricate castings. Whether for standard applications or those demanding unique materials as per customer requests, shell molding ensures precision.

Hot Box Process

The hot box process is another integral part of our offerings. In this method, resin – coated sand cores are cured in a heated box. This results in cores with high strength, enhancing the overall quality of the casting. It plays a crucial role in our molding & core – making procedures, enabling us to meet diverse customer needs.

Molding & Core Making

Our molding & core – making services are comprehensive and tailored to the requirements of resin coated sand casting. We combine the shell molding and hot box processes with advanced techniques to produce high – quality molds and cores. This allows us to handle a wide array of projects, from small, detailed components to large – scale industrial parts. Leesh’s ability to work with both standard and unique casting materials, coupled with our global export capabilities, makes us the ideal choice for all your resin coated sand casting needs.
