What is your minimum order quantity for custom parts?

We support single-piece prototypes and low-volume runs through CNC machining, 3D printing and urethane casting, and scale to mass production through die casting, injection molding and stamping. Share your target quantity and our engineers will recommend the most cost-effective process.

What tolerances can Sunmy Hardware hold?

Standard CNC tolerances are ±0.01 mm, and critical features can be held down to ±0.005 mm. Dimensions are verified with CMM inspection and documented in FAI reports before shipment.

How do you protect my drawings and intellectual property?

We sign a Non-Disclosure Agreement with you by email before collecting any 3D or CAD files. You work directly with the factory, so your data is never handed off to brokers.

Which quality documents are available with shipments?

Material certificates, RoHS compliance documents, First Article Inspection (FAI) reports and CMM dimensional reports can be supplied per project.

Which manufacturing processes are done in-house?

CNC machining and stamping are performed in our own facilities. Casting and surface finishing are completed by audited partners. All final quality control, CMM inspection and FAI are executed in-house by Sunmy engineers before global shipping.

Which CAD file formats do you accept?

We accept STEP, IGES, STL, DWG/DXF and PDF 2D drawings. Physical samples can also be reverse-engineered.

Product Description

Product Overview

At Shenzhen Sunmy Hardware Co., Ltd., we specialize in the bespoke manufacturing of high-precision Sheet Metal Brackets and Stamping Parts designed specifically for the electronic device industry. As seen in the product gallery, our capabilities cover complex geometries, from structural chassis components to intricate internal mounting plates.

Whether you require a robust internal support frame, a heat-dissipating shield, or a complex multi-plane bracket, Sunmy provides end-to-end solutions. We transform your CAD drawings into physical reality, ensuring that every bend, hole, and slot aligns perfectly with your assembly requirements. We are not just a manufacturer; we are your partner in structural hardware development.

Manufacturing Process & Craftsmanship

Our production facility utilizes a hybrid approach to meet both high-mix/low-volume prototyping and high-volume mass production needs.

🔆

Precision Laser Cutting & Turret Punching

For flat patterns with complex cutouts (like the circular plate shown), we utilize high-speed laser cutting to ensure burr-free edges and precise dimensions without expensive tooling costs for prototypes.

⚙️

CNC Bending & Forming

The multi-angled brackets in our portfolio demonstrate our advanced CNC bending capabilities. We achieve tight angular tolerances across multiple planes, ensuring the part fits seamlessly into compact electronic enclosures.

🏭

Progressive Die Stamping

For high-volume orders, we design and manufacture in-house tooling to ensure consistency and cost-efficiency.

✨

Surface Treatment

We offer various finishes including Zinc Plating, Nickel Plating, Powder Coating, and Anodizing to provide corrosion resistance and electrical conductivity/insulation as required.

Features & Advantages

✔ Choosing Sunmy for your hardware needs ensures you benefit from:
✔
Complex Geometry Support: As shown in the product images, we excel at producing parts with multiple bends, intricate slot patterns, and unique locking tabs.
✔
Scalability (Low MOQ to Mass Production): We support your product lifecycle from the initial prototype (using soft tooling/laser) to mass production (using hard tooling/stamping dies).
✔
Strict Quality Assurance: Every batch undergoes dimensional inspection. We ensure that hole positions and bend angles are precise to facilitate easy assembly on your production line.
✔
Design for Manufacturing (DFM) Support: Our engineering team reviews your drawings to suggest material or tolerance optimizations that reduce cost without sacrificing performance.

Technical FAQ

QQ1: What is the typical lead time for a custom sheet metal bracket?

A: Generally, prototypes can be finished in 3–7 days. For mass production, the lead time is typically 15–25 days, depending on the complexity and surface treatment requirements.

QQ2: Can you work from a physical sample if I don't have the 3D drawing?

A: Yes, Sunmy has strong reverse engineering capabilities. We can scan and measure your sample to generate the necessary CAD files for production.

QQ3: How do you handle tolerance control for complex bent parts?

A: We use high-precision CNC press brakes and utilize custom fixtures during the inspection process to ensure every dimension meets the print specifications.

QQ4: What materials are most commonly used for electronic device brackets?

A: SPCC (cold-rolled steel), SECC (galvanized steel), and Aluminum 5052/6061 are the most popular choices due to their balance of strength, weight, and cost. Stainless steel 304 is preferred when corrosion resistance is a priority.

QQ5: What is the minimum order quantity (MOQ) for custom sheet metal parts?

A: There is no strict MOQ for prototypes or small-batch orders — we can produce from a single piece using laser cutting. For stamped parts requiring hard tooling, the MOQ is typically negotiated based on tooling amortization and part complexity.

QQ6: Do you provide quality inspection reports with shipments?

A: Yes. We provide dimensional inspection reports (CMM or manual measurement) with every batch. First Article Inspection (FAI) reports can also be provided upon request to verify that the initial production run meets all drawing specifications.
