|
Critical Feature |
Engineering & Manufacturing Considerations |
|
Bearing & Shaft Bores |
Bore diameter, circularity, concentricity, and axial alignment directly impact compressor internal assembly and operational lifespan. |
|
Mounting Interfaces |
Precision hole locations and mounting-face flatness ensure coplanar alignment during vehicle installation. |
|
Sealing Surfaces |
Surface roughness (Ra), flatness, and freedom from porosity affect dynamic and static refrigerant sealing performance. |
|
Threaded Holes |
Thread pitch, depth, thread integrity, and particulate cleanliness must meet strict fastening specs. |
|
Locating Features |
Accurate positional placement ensures repeatable locating during automated secondary operations and final assembly. |
|
Machined Datums |
Establishing precise reference planes guarantees consistent location during subsequent multi-axis CNC operations. |
|
Internal Passages |
Complex passage geometry, surface smoothness, and casting soundness ensure uninhibited refrigerant and lubricant flow. |
|
Casting Walls & Ribs |
Uniform wall thickness distribution minimizes thermal distortion, structural flex, and internal casting stress. |
|
Pressure-Sensitive Zones |
Sound internal structure verified via non-destructive testing and leak inspection to withstand peak operating pressures. |
Integrated Manufacturing Solutions
Engineering & DFM Review:
Every part undergoes a Design for Manufacturability review analyzing casting feasibility, parting lines, draft angles, metal flow, shrinkage, machining allowances, datum selection, and tool accessibility.
Precision Aluminum Casting:
Casting establishes the primary structural envelope, incorporating cooling channels, bosses, and lugs while controlling alloy chemistry, melt cleanliness, shot speed, and cooling rates.
CNC Machining Operations:
High-precision multi-axis CNC operations execute tight-tolerance features, including fine boring for bearing cavities, face milling for flat sealing pads, and precision tapping for fluid ports.
Deburring & Automated Washing:
Housings undergo thorough deburring across internal cross-holes and high-pressure wash cycles to remove fine chips, fluids, and particulates according to cleanliness standards.
