Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques. In China, the lost-wax casting had been flourishing in BC 1,700 to BC 1,000, and today’s high-technology investment casting produced by Sinco Machine is the good combination of accuracy, repeatability, versatility and intergrity in a variety of metals and alloys.
Investment casting is generally used for small castings, but now we have been used to produce complete aircraft door frames, steel castings of up to 300 kg and aluminium castings of up to 30 kg.
