| Engineering & Design Validation |
Customer Collaboration |
2D/3D drawings and motor specifications are reviewed. |
| DFM & Tolerance Analysis |
Design is optimized for manufacturability, with bearing seat concentricity and alignment as key focus areas. |
| Mold Design |
High-precision tooling is designed with ejector systems, cooling channels, and draft angles suitable for bearing housings. |
| Tooling Fabrication |
CNC Machined Molds |
Core and cavity inserts are milled from hardened H13 tool steel for longevity and thermal stability. |
| EDM Detailing |
Complex internal features like bearing bores or ventilation paths are refined via Electrical Discharge Machining. |
| Heat Treatment |
Tool steel is hardened and nitrided for wear resistance in high-volume casting. |
| Aluminum Die Casting |
Material Selection |
A380, ADC12, or AlSi10Mg alloys are chosen for their strength, thermal conductivity, and pressure tightness. |
| High-Pressure Casting |
Molten aluminum (~660°C) is injected into the die under 1000–2000 psi to ensure dimensional accuracy and fine detail replication. |
| Solidification & Ejection |
Rapid cooling maintains structural integrity; ejector pins release the part without distortion. |
| Secondary CNC Machining |
Critical Feature Finishing |
Precision machining of bearing pockets, shaft bores, and mounting faces ensures alignment within ±0.01 mm tolerance. |
| Threading & Drilling |
Custom holes, tapped inserts, and assembly interfaces are machined per motor specs. |
| Flatness & Concentricity |
High-speed milling and inspection ensure smooth, vibration-free motor operation. |
| Surface Finishing |
Anodizing |
Adds corrosion resistance, electrical insulation, and aesthetic appeal (clear or black). |
| Powder Coating |
Durable, weather-resistant coating for industrial or outdoor environments. |
| Bead Blasting |
Creates uniform matte texture and removes minor surface defects before final coating. |
| Quality Control & Testing |
Dimensional Inspection |
CMM and go/no-go gauges ensure tight fits for bearings and shafts. |
| Material & Structural Testing |
Includes alloy certification, porosity checks, and mechanical stress evaluations. |
| Balance & Fit Validation |
Especially for dynamic components requiring rotational symmetry. |
| Packaging & Delivery |
Protection |
Each housing is individually packed with foam, anti-static bags, or trays. |
| Documentation |
Includes inspection reports, RoHS/REACH declarations, and Certificates of Conformance. |
| Logistics |
Ready for global shipment and integration into motor assemblies. |
