How to ensure high precision finished ring forging

To make an investment mold from a suitable investment material, such as paraffin; Repeat the process of coating and spraying refractory sand on the investment mold, hardening the shell and drying; Then the internal investment mold is dissolved to obtain the cavity; Roast the shell to obtain sufficient strength, burn off the residual investment material, and pour the required metal material; Solidification cooling, peeling after sand, so as to obtain high precision finished products. According to the product needs or heat treatment and cold work and surface treatment.

Manual modeling is still an important method for single piece small batch production of heavy castings. Manual modeling can adapt to various complex requirements and is flexible, and does not require a lot of process equipment. Can be used in sodium silicate sand, VRH method sodium silicate sand, organic ester sodium silicate self-hardening sand, clay dry, resin self-hardening sand and cement sand, etc.. In most cases, the stainless steel ring forging factory always have a lot of different processed products, first of all, will be made, stainless steel products, such as medical, after removing the corresponding heat treatment, Mosaic full circle or under the condition of equal size, to the construction site will be on complete different flange and pressure on the arc compound with container. The above is to ensure high precision ring forging method.
