Dynamic balancing machine base casting | Balancing machine bottom http://www.btjxjt.com The advantages of using lost foam and resin sand casting technology to cast the base of the dynamic balancing machine are that the resin sand mold has good rigidity and high initial strength during casting. This allows for the effective elimination of casting defects such as shrinkage and porosity by utilizing the graphitization expansion during the solidification process of cast iron, achieving less riser casting in the production process of gray iron castings, and even achieving riser free casting. In the production of balanced machine castings, polystyrene foam molding is used and furan resin self hardening sand molding is applied. When the molten metal is poured into the mold, the foam plastic pattern quickly vaporizes under the action of the high-temperature molten metal, burns and disappears. The molten metal replaces the position occupied by the original foam plastic, and cools and solidifies into a full mold casting with the same shape as the pattern

The base castings of the balancing machine are generally made using disappearing models, sand casting, resin sand, and cement sand molding. The material is high-quality high-strength cast iron HT250-300, with strong tensile strength, reasonable manufacturing, stable structure, high precision, wear resistance, long service life. Sand casting method has low cost, simple production process, and short production cycle.

The complex structure of large castings makes shrinkage difficult, and the shrinkage rate of castings decreases; The shrinkage rate of large castings varies depending on the material of the casting; The yielding ability of large castings is good, and the shrinkage rate of castings increases.

Botou Dingbo Machinery Factory specializes in the production of differential housing castings, axle housing castings, balance blocks, mud remover accessories, valve castings, well rings and covers, coal mill accessories roller sleeves, liners, wear-resistant hammers, heat-resistant cast iron accessories, agricultural machinery auto parts, forklift counterweights, elevator counterweights, civil air defense engineering castings, cast aluminum castings, carbon steel castings and other businesses. The production rate of ductile iron parts, especially small ductile iron parts, in the non riser casting process for differential housing is relatively low, generally only reaching 60% to 70%. To improve the process yield, riser free casting can be used, but it is generally believed that riser free casting is difficult to achieve success in small parts, especially in wet mold casting processes. It is generally believed that only under high-pressure molding conditions can small wet type riser free casting be achieved. But we have achieved riser free wet casting on two types of castings, the left housing of the BJ130 car rear axle differential and the right housing of the 3t forklift differential, under the condition of manual molding and core making. The genuine product rate is over 90%, and the process yield rate reaches over 93%.
