Introduction of cast iron gearbox housing:
Cast iron gearbox housing is usually made of high-strength and wear-resistant cast iron. Among them, gray cast iron and ductile iron are the two most common materials. Our product uses ductile cast iron, and spheroidal graphite is obtained through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron gearbox housing, especially the plasticity and toughness, thereby obtaining a higher strength than carbon steel.
Advantages of ductile iron gearbox housing:
1. In addition to ductile iron casting gearbox housing, we can also provide castings of various materials such as gray iron, stainless steel, copper, aluminum alloy, etc.
2. Our ductile iron casting gearbox housing adopts investment casting, sand casting, precision machining and other processes, combined with CNC milling, CNC lathe turning, drilling, welding, die casting, stamping and other processing methods to achieve high-precision manufacturing of complex structures.
3. Our ductile iron casting gearbox housing provides powder spraying, anodizing, electroplating, PVD coating, hot dip galvanizing, nickel plating, chrome plating, enamel coating and other surface treatment methods to prevent oxidation and corrosion of the product.

About us:
Dandong Hengrui Machinery Co., Ltd. insists on technological progress and strives to build the company into a modern foundry enterprise with low energy consumption, low emissions, high efficiency and environmental protection. In terms of technology, it has introduced and adopted advanced casting technologies such as high-pressure injection molding, shell core core making, and three-dimensional process design. In terms of casting equipment, it first introduced two detachable box-type FBOⅢ injection molding automatic production lines from Japan (box size: 605×505×200㎜), which can produce 120 sand molds per hour and 7,000 tons of castings per year. Later, it introduced a static pressure automatic production line with world-leading level (box size: 1000×800×350/300㎜), which can produce 90 sand molds per hour and 30,000 tons of castings per year, and the production scope has been broadened.
