Selection: To produce first-class pipe mold, we must have first-class raw materials. Our company use high-quality mold steel Cr12mov as raw material which is high wear resistance, toughness, resistance to high pressure, high hardness, strong quenching. Machining process: raw materials - materials testing - and exercise - Saws - Turning - Drilling - Turning - CNC precision turning - grinding - quenching - Hardness test - internal and external grinding - test - boxing. Features: mature manufacturing process, rich experience and standard production management build up the brand of BaiGuan. Use CNC machining of Japan, high precision; 10 years experience in R & D, the leading solution for uneven surface forming tube, bad angle, pipe problems generated in the process such as strain wrinkles, fingerprints, mechanical pattern, on the corner, concave angle ; and to form tolerance of roundness in less than 0.05mm; square tube on the angle does not exceed ¡À 0.05mm
