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.

Process & Manufacturing Insights

At Shenzhen Sunmy Hardware Co.,Ltd., our robust production ecosystem seamlessly integrates traditional casting durability with modern precision engineering.

Sand Casting Core

The foundational structure is formed using professional Sand Casting Services, allowing for complex geometries and dense, resilient metal structures capable of withstanding high-stress environments.

Precision CNC Machining

Post-casting, the raw parts are transferred to our advanced CNC Machining Centers. Here, critical dimensions such as inner bores, mounting flanges, and bolt holes are meticulously machined to achieve exact functional tolerances.

Stringent Tolerances

Our casting processes strictly adhere to ISO 8062 CT8-CT12 tolerance standards, ensuring that the foundational cast is highly accurate even before final machining.

Technical FAQ

What is the minimum order quantity (MOQ) for custom wheel hubs?

Shenzhen Sunmy Hardware Co.,Ltd. is dedicated to supporting your product development cycle. We offer flexible MOQs depending on the specific tooling requirements and manufacturing complexity. We also gladly provide samples for testing and validation prior to mass production.

How do you guarantee the quality and dimensions of the casting parts?

Quality is paramount to our manufacturing philosophy. We utilize highly precise CMM (Coordinate Measuring Machine) equipment to conduct 100% inspections on critical dimensions. Furthermore, we issue comprehensive material and dimensional test reports with shipments and welcome third-party inspections for your absolute peace of mind.

What formats do I need to submit my designs in?

Our engineering team is equipped to handle standard industry formats. For the most accurate quoting and production, we recommend providing 3D models in IGES or STEP format, accompanied by 2D PDF or CAD drawings detailing specific tolerances and surface finish requirements.

What is the typical lead time for a new custom order?

Lead times generally involve two phases: tooling/mold creation and mass production. Tooling and initial sample production typically take a few weeks. Once the sample is approved, mass production lead times are scheduled based on order volume. Our team will provide a precise, reliable timeline during the initial quotation phase.

What materials and tolerance standards are applied during production?

We primary work with iron, steel, and custom metal alloys. Our foundational casting process adheres strictly to ISO 8062 CT8-CT12 tolerance standards, followed by precision CNC machining to achieve tighter critical tolerances as requested by your engineering drawings.

Are samples and third-party quality inspections supported?

Yes, custom samples can be provided upon request prior to bulk mass production. Additionally, we support and accommodate full third-party quality inspections to ensure all custom components meet your operational standards.
