Product Overview
At JYH Precision Machining, we specialize in manufacturing high-precision aluminum die casting components combined with CNC secondary
machining to achieve superior dimensional accuracy, surface finish, and
functional reliability.
The product shown above is a precision die-cast aluminum hub/flange housing, widely used in automotive, industrial equipment, robotics, and
electromechanical assemblies. This part demonstrates our capability
to integrate die casting efficiency with CNC machining accuracy, delivering production-ready components that meet tight tolerances
and demanding performance requirements.
With over 10 years of hands-on experience in precision manufacturing, our engineering team ensures every part is produced with strict
quality control — from mold design to final inspection.
Manufacturing Process
This component is produced using a hybrid manufacturing approach:
- High-Pressure Aluminum Die Casting – for near-net shape, structural integrity, and cost efficiency
- CNC Precision Machining – for critical dimensions such as bore diameter, mounting faces,
and threaded holes
- Deburring & Surface Preparation – to remove sharp edges and improve appearance
- Quality Inspection (CMM + Manual Gauges) – to ensure dimensional compliance
- Optional Surface Treatment – anodizing, powder coating, painting, or custom finishes
This process combination allows us to achieve both high-volume efficiency and precision-level accuracy.
