Question 1

What is your minimum order quantity for custom parts?

Accepted Answer

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.

Question 2

What tolerances can Sunmy Hardware hold?

Accepted Answer

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.

Question 3

How do you protect my drawings and intellectual property?

Accepted Answer

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.

Question 4

Which quality documents are available with shipments?

Accepted Answer

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

Question 5

Which manufacturing processes are done in-house?

Accepted Answer

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.

Question 6

Which CAD file formats do you accept?

Accepted Answer

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