Precision casting, also known as near net shape casting, is a high-end manufacturing technology that has become the core support for modern agricultural machinery components, perfectly addressing the harsh operating conditions of agricultural equipment and the strict requirements for component performance. Our precision cast agricultural machinery parts are independently developed and produced based on the unique working characteristics of agricultural machinery, integrating advanced casting processes, high-quality material selection and strict quality control, committed to providing reliable, durable and efficient core components for global agricultural machinery manufacturing, helping to promote the modernization and intelligence of agricultural production.
Our precision cast agricultural machinery parts are designed to adapt to the harsh working environment of agricultural operations—long-term resistance to soil wear, moisture corrosion, heavy load impact and chemical erosion from fertilizers and pesticides. Covering a full range of core components for agricultural machinery, the products are widely used in tractors, combine harvesters, seeders, cultivators and other key agricultural equipment, involving power transmission, tillage operation, hydraulic control, harvesting and processing and other core systems. With the core advantages of high dimensional accuracy, excellent surface finish, stable mechanical properties and strong forming ability, the parts can directly meet the assembly requirements with minimal subsequent machining, greatly improving the assembly efficiency of agricultural machinery and reducing the overall maintenance cost.
Adopting advanced investment casting and shell mold casting processes, parts achieve high dimensional accuracy (up to ±0.13mm for 20mm parts) and surface roughness of Rmax 4S~12S. This reduces machining allowance by over 80% compared to traditional sand casting.
We use high-performance materials including alloy steel (40Cr, 4140), ductile iron (QT600-3), and stainless steel. Parts feature uniform grain structure, extending service life by 30% or more under high-load conditions.
One-time forming for complex structures like gearbox housings and differential gears. Supports custom development from 0.1kg to 100kg based on drawings and specific performance requirements.
Near net shape forming reduces material waste and energy consumption. Low failure rates and high durability significantly lower the frequency of maintenance and replacement for end-users.
