In our foundry silicasol lost-wax process is used. Investment casting which is based on silicasol lost-wax process finds its wide application in the field of steel components with complicated geometries where high precision surface is required, thus considerably reducing the machining cost.
　　By using silicasol lost-wax process, we can manufacture components of copper, carbon steel or stainless steel alloys according to DIN, EN, ASTM, BS, JCSI.Turning, milling, drilling, thread cutting will be adopted depending on the specific requirements of the drawing and the technical specifications.The surface treament includes analysis wet chemically or by x-ray spectrometer, 3-coordinate computerised numerical control.To To quarantee the quality of the products, analysis wet chemically or by x-ray spectrometer, 3-coordinate computerised numerical control measuring machine, pressure inspection up to 200 bars, mechanical values for tensile strength, yield stress, notched bar impact tenacity, x-rays, metallography will be performed.
