Material Options

We primarily use the following materials for our cast rocker arms:

• Cast Iron: Known for its excellent castability and wear resistance, suitable for medium-load applications.
• Cast Steel: High strength and good toughness, ideal for applications subject to heavier loads, such as heavy machinery and automotive engines.
• Aluminum Alloy: Lightweight design with good corrosion resistance, widely used in the aerospace and automotive industries, especially where weight reduction is critical.

Production Process

The production process for cast rocker arms includes several key steps:

1. Mold Design:

   • Design and manufacture high-precision casting molds based on customer requirements to ensure accurate product dimensions and shapes.

2. Melting and Pouring:

   • Melt the selected metal material at high temperatures and then pour it into the molds under vacuum or protective atmospheres to ensure the density and smooth surface of the castings.

3. Cooling and Demolding:

   • After cooling, the castings are removed from the molds and undergo preliminary surface treatment to remove excess material and burrs.

4. Heat Treatment:

   • Perform heat treatment on the cast rocker arms to enhance hardness and toughness, ensuring durability under working conditions.

5. Finishing:

   • Carry out machining to achieve precise dimensional requirements and surface finish, ensuring compatibility with other components.

Application Fields

Cast rocker arms are widely used across various industries, including:

• Automotive Industry: Utilized in components such as engines, suspension systems, and transmissions, ensuring vehicle stability and safety.
• Construction Machinery: Serve as power transmission and control elements in heavy equipment like excavators and bulldozers.
• Aerospace: Used in structural components of aircraft, enduring high loads and high-temperature environments.
• Industrial Equipment: Act as essential transmission and control parts in various machines and equipment.

Quality Control

We strictly adhere to ISO 9001 quality management system standards, ensuring that each cast rocker arm undergoes comprehensive quality inspection before leaving the factory, including:

• Material Inspection: Verifying that the raw materials meet specified chemical and physical properties.
• Dimensional Measurement: Using high-precision measuring instruments to check the dimensions and tolerances of the castings.
• Mechanical Performance Testing: Conducting tensile, impact, and hardness tests to validate mechanical properties.
• Surface Quality Inspection: Ensuring the castings are smooth and defect-free, meeting customer requirements.
