OEM

Custom OEM Solutions

Tailored designs requiring unique mounting points, IP67 sealing, and non-standard geometries.

From Tooling to Production Without Compromise

We don't believe in one-size-fits-all solutions. Our engineering team thrives on complex challenges, thin walls, unusual geometries, and tight tolerances.

Our high-pressure die casting process ensures exceptional dimensional consistency. This means your custom design maintains the exact same precision whether you order 1,000 pieces or 100,000 pieces.

  • DFM (Design for Manufacturing): We collaborate with your engineers to optimize draft angles, reduce porosity, and enhance functionality.
  • High Volume Efficiency: Fast cycle times guarantee reliable delivery schedules for large-scale manufacturing lines.
  • Turnkey Solutions: From cutting the steel dies to high-pressure injection and final CNC machining, we handle it all under one roof.

Premium Die Casting Alloys

Selecting the right material is critical for thermal management and durability. We specialize in high-grade non-ferrous metals.

A380 / A383 Aluminum

The industry standard for aluminum die casting. Offers an exceptional combination of material properties, excellent thermal conductivity, and resistance to hot cracking.

A360 Aluminum

Chosen for applications requiring excellent pressure tightness and high corrosion resistance. Perfect for liquid-cooled motor housings and demanding environments.

Zinc Alloys (Zamak 3 & 5)

Ideal for smaller, highly intricate motor components requiring extreme dimensional stability, thinner walls, and superior finishing characteristics.

Our Streamlined Manufacturing Process

How we take your custom motor housing from a CAD file to a finished, ready-to-install component.

1

Design & Tooling

We review your CAD files, optimize for die casting, machine the precise steel dies, and simulate the injection flow to eliminate defects.

2

High-Pressure Injection

Molten metal is injected into the steel dies under extreme pressure, rapidly forming net-shape housings with excellent surface finishes.

3

CNC Machining

While die casting produces near-net shapes, multi-axis CNC centers refine bearing bores, mounting faces, and shaft alignments to ±0.0002".

4

Finishing & Assembly

Parts undergo deflashing, surface treatment, IP sealing, and serialization before rigorous final inspection and global shipping.

Production Volume Optimized for medium to high volume (1,000 to 100,000+ units).
Quality Control Testing

Zero Defect Quality Control

A motor housing failure is catastrophic. That is why our quality assurance process is integrated into every single step of production, ensuring operational excellence in the field.

CMM Dimensional Inspection

Touch-probe verification guarantees all CNC machined surfaces meet exacting blueprints.

Dynamic Balancing

Ensures the housing promotes rotational stability to prevent motor vibration.

Non-Destructive Testing

X-ray and ultrasonic testing to verify internal structural integrity and lack of porosity.

Leak & Pressure Testing

Critical for liquid-cooled housings to ensure IP67 sealing and fluid retention.

IATF 16949:2016 Certified Quality

For custom motor housing manufacturers, especially in the automotive sector, certification is non-negotiable. Our foundry facility is certified to the stringent standard, demonstrating our commitment to defective prevention, reduction of waste, and continuous improvement.

  • Global recognition for automotive quality management systems.
  • Ensures strict process controls are in place from design to delivery.
  • Mandatory requirement for critical Tier 1 and Tier 2 suppliers.
IATF 16949:2016 Certification

Frequently Asked Questions

Common questions from engineering and procurement teams.

What is the typical lead time for die casting tooling?

Because die casting requires precision-machined steel dies, initial tooling and first-article samples typically take between 4 to 8 weeks depending on the complexity of the housing.

Can you cast complex internal cooling jackets?

Yes. We specialize in using advanced die design and slides to create intricate internal geometries like liquid cooling jackets that are highly difficult to achieve with traditional machining alone.

Do you handle low-volume orders?

Die casting is most cost-effective for medium to high-volume runs (1,000+ units) due to the initial tooling investment. However, once the die is created, the unit cost drops significantly compared to other casting methods.

Can you handle secondary surface finishing?

Absolutely. Beyond precision CNC machining, we offer a full suite of finishes including anodizing, hardcoating, powder coating, passivation, and electropolishing, tailored to your environmental requirements.

Will you sign a Non-Disclosure Agreement (NDA)?

Yes. We routinely work with proprietary designs for major OEMs in the medical and aerospace sectors. We are happy to sign an NDA before you share any CAD files or blueprints.
