Precision casting, also called as investment casting or lost waxing casting, is a casting method in which fusible one-off mould and one-off pattern (core) are used to shape casts. Casts produced with this method have smooth surfaces, accurate dimensions and high geometrical precision. This method is suitable for shaping complicated thin-wall parts, instrumental to improving product performance, reducing structural weight and manufacturing cost, so it’s applied more and more widely in industrial production.

Beijing Changhang Investment Casting Co., Ltd. has many years of production experiences in investment casting and has mighty technical strength. Through years of research and testing, the company has developed the most advanced, mature and stable production process in the industry, with the quality and technical content of its high-temperature alloy casts taking the leading position in China. The products’ dimensional accuracy can be up to ±0.3mm/100mm; surface roughness Ra up to 12.5-1.6μm; weights of casts from several grams to dozens of kilograms; local wall as thin as 0.5mm.
