Casting process for large ring gear

The casting process of large gears from professional manufacturers is a delicate and complex project. Starting from the drawings provided by the customer, the technical team will conduct detailed analysis and simulation to ensure the feasibility of the casting process.

Mold making is the first step in casting. According to the design drawings, the mold is carefully prepared using wood molds, sand molds, etc. During the melting and casting process, technicians strictly control the chemical composition and addition of various elements to meet the performance requirements of the gears. During the pouring process, temperature, speed and time are precisely controlled. Make sure there are no bubbles, no inclusions inside the casting, and uniform density. Large-scale casting processing manufacturers will demould the large gear after cooling, and then perform cleaning work such as grinding and sand cleaning to remove surface debris and burrs. Gears also need to undergo heat treatment, such as normalizing, annealing, quenching, tempering, etc., to improve the material structure and improve mechanical properties.

In the finishing stage, the gears undergo turning, milling, grinding and other processes to achieve the required dimensional tolerance and surface roughness requirements. Every step of production is accompanied by strict quality inspection, including
Dimensional inspection, appearance inspection, chemical composition analysis, mechanical property testing, etc. ensure that the final product meets quality standards. Professional manufacturers produce high-quality large gears through advanced casting techniques and strict quality control, providing reliable transmission components for mechanical equipment, automobiles, aerospace and other fields.
