Centrifugal Casting
All raw materials using silica sol and zircon powder are dried at 450 degrees before melting to avoid hydrogen corrosion. They are then controlled by PLC and protected by argon gas before entering the casting process. The entire process is used to create components with a very pure and highly compressed structure. The product is free of impurities and is suitable as a first-class high-performance material.
Static Casting
Using a mixture of furan resin, curing agent, and quartz sand for molding, it is commonly used for casting complex large castings and static castings with a wall thickness greater than 15mm. Spraying zirconium powder coating on the mold cavity, high temperature resistance, good surface quality of castings, high mold strength, suitable for producing complex castings with large wall thickness; Sand has good collapsibility, easy cleaning, good molding, low gas generation, good thermal stability and breathability; Reduce casting defects such as sand sticking, sand inclusion, sand holes, porosity, shrinkage, and cracks.
Precision Casting
Using silica sol, zircon powder, medium temperature wax, and mullite sand to make shells, it is mainly used for producing castings with thinner wall thickness, such as twisted sheets and small Y-shaped pipes. High surface smoothness, with a roughness of up to 3.2; The shell has high strength, small deformation of the casting, and high dimensional accuracy. Small and complex casting components with a size range of 25 kilograms and a length of 400 millimeters are best manufactured using precision casting technology. Whether we provide rough or finished products, or ready to use components, this provides extremely good cost-effectiveness.
