Product Description
Yile Machinery is an expert OEM supplier specializing in the fabrication and precision machining of large steel housings for industrial speed reducers, gearboxes, and transmission systems. We deliver robust, dimensionally accurate, and fully finished components tailored to your exact engineering specifications.
Our fabricated housings serve as an engineered, high-performance alternative to traditional cast iron or steel castings, offering superior design flexibility and quicker turnaround for custom and low-volume production.
For demanding powertrain applications, a fabricated steel housing provides significant benefits over a casting:
Enhanced Structural Integrity: Welded steel plate construction eliminates the risk of internal casting defects such as porosity or voids, ensuring a solid and reliable structure capable of handling high torque and vibration.
Optimal Design Flexibility: Break free from the constraints of casting patterns. Fabrication allows for complex internal ribbing, optimized wall thicknesses, and integrated mounting points without expensive pattern modifications.
Faster Prototyping & Production: By avoiding the long lead times and high costs associated with creating casting patterns, we can deliver prototypes and small production runs more quickly and cost-effectively.
Superior Material Properties: Utilize high-strength steel plates to achieve a better strength-to-weight ratio compared to standard cast iron.
We manage the entire production process in-house to guarantee quality, accuracy, and accountability at every stage.
1. Heavy Plate Fabrication
We start with certified carbon or alloy steel plates, cut to precise shapes using CNC plasma and laser systems.
Our expert welders assemble the components into a rigid weldment, using advanced techniques to ensure deep penetration and flawless joints.
2. Post-Weld Stress Relieving
This is a non-negotiable step for precision components. The complete fabrication is heat-treated in a furnace to relieve all internal stresses from welding, guaranteeing dimensional stability during machining and service.
3. Large-Format Precision Machining
After stress relieving, the housing is machined on our large-scale CNC equipment (boring mills, gantry mills). We machine all critical features to tight tolerances, including:
Gear and bearing bores
Shaft seal surfaces
Flat and parallel mounting faces
Dowel pin holes for precise alignment
4. Comprehensive Quality Assurance
Final inspection is performed using CMM (Coordinate Measuring Machines) and laser trackers to verify all dimensions against your drawings. We also conduct NDT (Non-Destructive Testing) on welds upon request.
We build custom housings for a wide array of heavy-duty equipment:
Industrial Speed Reducers and Gear Drives
Multi-Stage Transmission Cases
Wind Turbine Gearboxes
Mining and Construction Equipment Drivetrains
Marine Propulsion Systems
