Precision Deep-drawn Cup-Shaped Stamping Shell for Motor Housings with Customizable Geometry and High Wear Resistance

We produce custom deep-drawn cup-shaped stamping shells mainly used as motor housings. Made by precision deep-draw stamping process, these housings are integrally formed from metal sheet material. The seamless cup-style structure delivers steady wall thickness and good dimensional consistency for assembly.

This metal shell acts as a sturdy protective housing, shielding rotors, stators, bearings, magnets and other internal motor parts. Its circular cup-shaped profile ensures good structural rigidity and flat mounting surfaces for downstream assembly work.

We build parts based on your 2D drawings, 3D CAD files or physical samples. Material choices cover carbon steel, cold-rolled steel, stainless steel, aluminum, copper and brass to fit different working conditions.

We can add secondary operations including trimming, piercing, flanging, tapping and machining. A full range of surface finishes is also available: zinc plating, nickel plating, powder coating, anodizing, passivation and polishing.

Our deep-drawn shells are widely adopted for BLDC motors, automotive actuators, pumps, fans, industrial equipment and home appliance motor assemblies.

• Industrial Equipment Motors – Suitable for industrial motors, compressors and automation machinery needing stable metal enclosures.
• Household Appliance Motors – Matching motor components for vacuum cleaners, washing machines, kitchen machines, air-conditioners and home ventilation fans.
• Pump & Fan Units – Compact cup-style housings for pumps and fan assemblies, balancing dimension accuracy, corrosion resistance and mechanical strength.

We deliver end-to-end OEM & ODM deep-draw stamping solutions from mold development to finished goods.

You may provide us with:

• 2D engineering drawings
• 3D CAD data
• Original physical samples
• Material grade & thickness requirements
• Tolerance & surface-finish specs
• Expected order volume

Our engineering team will review your project, suggest suitable material, wall thickness, forming workflow and secondary processes.

Customizable features include: Different shell diameters, drawing depths, flanged edges, mounting holes, vent holes, embossing, reinforcing ribs, stepped profiles, press-fit structures, welding spots and threaded holes. Multi-stage deep-draw combined with stamping will be applied for complex shapes to improve forming stability.

Xiamen METS Industry & Trade Co., Ltd., founded in 2006 in Xiamen, focuses on custom stamping die design, deep-draw forming and precision sheet-metal components, serving customers across Europe, North America and Asia.

We keep the full workflow in-house: tooling design, die making, stamping production and quality inspection. Customers can finish the whole project with one single supplier, from prototype validation to mass shipment.

Our core capabilities:

• Precision deep-drawing
• Progressive & compound die stamping
• Sheet-metal bending & forming
• Blanking, piercing and flanging
• CNC secondary machining, welding & partial assembly
• Independent custom stamping-die development
• Coordinate surface-treatment outsourcing
• Complete OEM / ODM manufacturing

For motor-housing projects, our in-house mold team optimizes deep-draw technology before mass production, lowering forming defects and improving batch consistency. We also supply related motor parts: motor end covers, stator & rotor lamination silicon-steel stamping components, to help customers source multiple motor hardware in one place.

Quality supervision runs through the whole production cycle, not only final inspection.

• Raw incoming material checking
• Material thickness & grade verification
• Tooling dimension inspection
• First-article approval
• In-process dimension sampling
• Deep-drawn surface appearance check
• Critical-size measurement
• Final visual inspection
• Pre-shipment random sampling

We can follow ISO 9001 quality standards and provide special inspection documents upon your request.

Case 1: Automotive Motor Housing – We produce deep-drawn stamped shells for vehicle motors. Process combines deep drawing, trimming and piercing to deliver assembly-ready finished housings.

Case 2: Industrial Motor Shell – Custom cylindrical deep-drawn shells for industrial motors. We tune material and wall thickness according to strength, weight, anti-corrosion and order-volume needs.

Case 3: Household-Appliance Motor Components – Stable-tooling deep-drawn shells for home-appliance motors, ensuring consistent dimension performance under large-volume orders.

Case 4: New-product Custom Engineering Parts – We support prototype trial for new motor designs based on drawings or samples, then optimize mold and forming process for serial mass production.

Precision Deep-drawn Shells for Reliable-performance Motors

A motor housing is far more than a simple metal cover. Dimensional accuracy, uniform wall thickness, mechanical rigidity and assembly compatibility directly decide the whole motor's service life.

Our deep-draw stamping technology manufactures integrated cup-shaped motor housings with stable repeatable quality. Compared with multi-piece welded shells, one-piece deep-drawn structures reduce joints and extra assembly steps while keeping high mechanical strength and compact size.

For motor OEM clients, our value is more than stamping production. We offer technical support covering drawing review, deep-draw die development, sample trial, quality testing and bulk delivery.

No matter you need corrosion-resistant stainless-steel shells for harsh environments, cost-effective carbon-steel housings for industrial motors or lightweight aluminum shells, METS will offer customized solutions matching your requirements.

Just send over your drawing or sample, our engineers will evaluate structure, material, mold scheme and production process for your project.

Yes, OEM & ODM are our core services. We accept 2D drawings, 3D CAD or physical samples to develop custom parts.

Common options: carbon steel, cold-rolled steel, stainless steel, aluminum, copper, brass. Material suggestion depends on strength requirement, anti-corrosion demand, weight, conductivity and drawing depth.

Normally 0.2-3.0 mm. Real feasible thickness depends on material grade, shell diameter and drawing depth.

Absolutely. Piercing, punching, trimming, flanging and embossing can be integrated into the production process.

Key critical dimensions can reach ±0.01 mm. Real tolerance should be confirmed against your engineering drawing.
