Selection of Automotive Castings

Agricultural machinery components are the core parts that make up agricultural machinery. Their basic characteristics can be summarized from the aspects of function, structure, material, usage environment, and quality requirements.

Functional Characteristics
High Specialization: Components are designed for specific agricultural needs, such as plowshares for breaking soil, disc harrow blades for soil crushing, and piston rings for sealing the combustion chamber.

High Reliability: Due to the urgency of the farming season, components need to operate stably within a limited service life with a low failure rate.

Adaptation to Complex Environments: They need to work continuously under harsh conditions such as outdoors, dusty, high humidity, and extreme temperatures.

Structural and Material Characteristics
Wear and Corrosion Resistance: Often made of high-strength alloy steel (such as 65Mn, 60Si2Mn, manganese-boron steel), wear-resistant cast iron, and some parts are heat-treated to enhance hardness and toughness.

Standardized Design: General parts such as bearings, gears, and V-belts follow national standards (such as GB/T 1804-m), facilitating interchangeability and maintenance.

Modular Trend: Some manufacturers develop modular component systems compatible with multiple brands of machines to enhance universality. ...
