CuZn40 Brass Die Casting Solution for Agricultural Pulley Components
Project Overview – Performance Requirements of Pulleys in Agricultural Machinery
Pulleys in agricultural equipment are exposed to harsh operating conditions, including dust, vibration, moisture, and heavy cyclic loads. These components must maintain dimensional accuracy, resist corrosion and abrasion, and transmit power efficiently. Die casting with CuZn40 brass provides high mechanical strength, excellent wear resistance, and consistent quality for pulleys operating in open-field environments.
Material Selection – Why CuZn40 Brass is Ideal for Agricultural Pulleys
CuZn40 is a high-zinc brass alloy offering excellent tensile strength, high surface hardness, and superior castability. Its toughness and resistance to dezincification make it ideal for parts exposed to outdoor and mechanical stress. CuZn40 also supports post-machining to achieve a precise fit for shafts and keyed transmission interfaces.
Manufacturing Process Breakdown
Copper Alloy Die Casting with CuZn40
Using copper die casting, we form pulley bodies with integrated hubs, grooves, and web structures in a single cycle. Optimized die filling and venting ensure consistent material density and porosity-free surfaces. We control critical wall thickness within ±0.1 mm to ensure balance and rotational stability at high speeds.
Precision Post Machining for Shaft Fit and Balance
After casting, post machining is used to define bores, keyways, and pulley alignment faces. Tolerances are maintained within ±0.05 mm to ensure concentricity, reduce vibration, and support efficient torque transmission from the motor to the driven components in farm equipment.
Surface Treatment – Shot Blasting for Durability
Shot blasting (metal media blasting) is applied to enhance the surface durability and aesthetic of the brass pulley. This process removes residual oxide, evens the texture, and improves fatigue resistance by inducing compressive stress. The result is a matte finish suitable for exposed agricultural machinery components.
