Custom Steel Castings for OEM & Heavy Equipment

Product Description

Yile Machinery is a turnkey manufacturing partner for custom steel castings, specializing in complex, fully-machined components for OEMs and the heavy equipment industry.

The excavator bucket arm link shown here exemplifies our integrated capabilities. We transform raw materials into precision-finished, ready-to-install parts that meet the rigorous demands of construction, mining, and agricultural machinery.

The Advantage of Casting for Structural Components

For complex structural parts like machine arms, links, and frames, casting offers significant advantages over fabrication (welding multiple plates together):

  • Superior Structural Integrity: A single, solid cast component eliminates weld seams, creating a monolithic part with a more uniform stress distribution and greater fatigue resistance.

  • Complex Geometries: Casting allows for the creation of intricate shapes and internal features that are impossible to achieve through fabrication or machining alone.

  • Cost-Effective Production: For series production, casting is often more economical than fabricating and machining complex assemblies, reducing both labor and material waste.

Our Integrated "Casting + Machining" Solution

We provide a seamless, single-source solution from raw casting to finished part, saving you time and simplifying your supply chain.

  1. Engineering & DFM: We review your drawings and provide Design for Manufacturability (DFM) feedback to optimize your part for quality and cost-effectiveness.

  2. Sand Casting: Using high-quality patterns and sand molds, we pour your components from specified grades of carbon or alloy steel.

  3. Heat Treatment: Castings undergo controlled heat treatment cycles (normalizing, quenching, tempering) to achieve the precise mechanical properties required for strength, toughness, and durability.

  4. Precision CNC Machining: Our in-house machine shop is equipped with advanced CNC lathes, milling centers, and boring mills to machine castings to your exact dimensional tolerances.

  5. Quality Assurance: Every part is subject to rigorous inspection, including dimensional checks (CMM), material analysis, and Non-Destructive Testing (NDT) to ensure flawless quality.

Materials & Applications

We cast a wide range of materials to meet your specific application needs:

  • Low-Alloy Structural Steels (e.g., Q345B / S355 / ASTM A572): Excellent combination of strength, toughness, and weldability for structural components.

  • Medium-Carbon Steels (e.g., C45): For parts requiring higher strength and hardness.

  • Custom Alloy Steels: Formulated for specific wear, impact, or strength requirements.

Our components are vital to the performance of:

  • Construction & Mining Machinery: Excavator booms, arms, links, counterweights, and chassis parts.

  • Agricultural Equipment: Tractor frames, implement hitches, and gearbox housings.

  • Industrial Machinery: Press frames, machine bases, and large structural mounts.
