Description

Notice to Buyers: This custom aluminum motor casing is a client-owned OEM component displayed strictly to demonstrate our precision aluminum die-casting, complex tooling design, and CNC machining capabilities. It is not available for standard off-the-shelf purchase.
Product Application & Material Choice
Engineered for heavy-duty industrial electric motors, hoists, and cranes, this high-performance aluminum motor casing provides structural protection and rapid heat dissipation. Cast from high-fluidity ADC12 / A380 aluminum alloy, this motor casing achieves an optimal balance between lightweight structural integrity, mechanical durability, and high thermal conductivity.
Key Manufacturing & Engineering Highlights
-
Complex Heat-Dissipation Fins: Features vertically integrated, thin cooling fins designed to maximize overall surface area. Our advanced mold flow layout ensures complete molten metal filling throughout these thin-wall sections without cold shuts or flow mark defects on the final motor casing.
-
Precision Machined Bearing Seats & Flanges: Critical interior surfaces, bearing locations, and mounting face pads of the motor casing undergo post-casting precision CNC milling and boring (conforming to ISO 2768-m tolerances) to ensure perfect shaft alignment and vibration-free motor operation.
-
Robust Surface Finishing (KTL/E-Coating): Treated with a high-durability KTL (Cathodic Dip Coating) finish to protect the motor casing enclosure against moisture, oxidation, industrial oil contamination, and harsh environmental exposure.
-
Dense Wall Structure for Sealed Enclosures: High-pressure injection prevents continuous porosity, ensuring structural integrity for sealed terminal boxes and flange joints.
Quality Assurance & Inspection Standard
Every custom die-cast motor casing component undergoes rigorous quality control to meet strict industrial specifications:
-
100% Visual Full Inspection: Complete screening for surface defects, flash remnants, and parting line uniformity.
-
Coating Adherence Testing: Cross-hatch adhesion test to ensure the KTL coating on the motor casing will not peel or flake under stress.
-
Salt Spray Exposure Testing: Verifies long-term anti-corrosion resistance in severe operating environments.
-
Thread & Dimensional Checks: 100% gauge verification on all CNC tapped holes and mounting features.
