Resin coated sand has become an essential material in the modern foundry industry. It is widely used for core and mould production, ensuring high-quality castings across various industries. At Sunshell Industries, we specialize in both solid resin coated sand (SRCS) and liquid resin coated sand (LRCS), offering tailored solutions for diverse applications.
What is Resin Coated Sand?
Resin coated sand is natural silica sand coated with thermosetting resin. This combination creates a high-strength, smooth, and heat-resistant material that is ideal for moulds and cores in foundry operations.
Types of Resin Coated Sand
- Solid Resin Coated Sand (SRCS):
- Pre-coated and ready to use.
- Offers excellent hot strength, uniformity, and low gas emission.
- Suitable for high-precision castings.
- Liquid Resin Coated Sand (LRCS):
- Resin is added to sand in liquid form during the process.
- More flexible and cost-effective for certain applications.
- Allows better control of binder levels.
Benefits
- Improved casting quality: Smooth surface finish and fewer defects.
- Dimensional accuracy: Helps in maintaining precise measurements.
- Consistency: Uniform coating ensures reliability in mass production.
- Eco-friendly options: Newer formulations reduce emissions.
Resin coated sand is not just a raw material — it is the foundation of efficiency, precision, and sustainability in the casting process.
