Product Detailed Description
Our gravity‑cast aluminum alloy housing is engineered for heavy‑duty industrial equipment. Adopting gravity casting process, the workpiece features compact internal structure, high mechanical strength and excellent stability. Secondary CNC machining ensures precise hole positions, flat mating surfaces and consistent assembly accuracy.
We deliver one‑stop manufacturing solution: casting → rough machining → precision CNC processing → deburring → surface treatment. All parts are inspected dimension‑wise before shipment to guarantee interchangeable assembly performance.
✅ We accept fully custom projects: drawings or samples are welcome. We can adjust material grade, wall thickness, hole layout and surface finish according to your actual working conditions.

Application Scenarios
Industrial equipment housing, mechanical gear box housing, power unit casing, automation equipment components, new‑energy equipment structural parts, general machinery cast housing.
FAQ
Q1: Can you produce according to my drawings or samples? A: Yes. We support OEM. Please send us 3D files or 2D drawings with dimension requirements; physical samples are also acceptable for reverse engineering.
Q2: What is your normal tolerance range? A: For CNC machined surfaces we can reach ±0.01 mm. Raw casting tolerance follows casting standard. We will confirm tolerance feasibility before quotation.
Q3: What surface finishes do you offer? A: Sand blasting, anodizing, hard anodizing, powder coating, spray painting are available. Please tell us your anti‑corrosion and appearance requirements.
Q4: What about lead time? A: Sample lead time: 15‑25 working days. Mass production lead time depends on order quantity, we will confirm exact schedule on quotation.
Q5: Do you offer quality inspection report? A: Dimension inspection report can be provided upon request. All goods go through full‑check before delivery.
