Question 1

What tolerances can Sunmy Hardware hold on CNC machined parts?

Accepted Answer

Critical CNC-milled and turned features can be held to ±0.005 mm, with ±0.01 mm achievable as a standard on precision features. Final achievable tolerance depends on material, feature size and geometry, and is confirmed during the engineering (DFM) review before production.

Question 2

Which manufacturing processes are performed in-house?

Accepted Answer

CNC machining and metal stamping are performed in Sunmy-owned facilities. Casting and surface finishing are produced by audited partner plants. All final quality control, CMM dimensional inspection and First Article Inspection reports are executed in-house by Sunmy engineers before shipment.

Question 3

How is my CAD data and intellectual property protected?

Accepted Answer

Sunmy signs a Non-Disclosure Agreement with your team by email before any 3D or CAD files are collected, and you communicate directly with the factory, so drawings are not handed off through trading intermediaries.

Question 4

What quality documents are supplied with shipments?

Accepted Answer

Material certificates, First Article Inspection (FAI) reports and CMM dimensional reports are available, together with RoHS compliance documentation where required.

Question 5

Do you support prototypes and low-volume production?

Accepted Answer

Yes. Sunmy supports rapid prototyping and low-volume manufacturing through CNC machining, 3D printing and urethane casting, then scales the same part into die casting, stamping or injection molding for volume production.

Question 6

How fast do your engineers respond to a new project?

Accepted Answer

Engineers respond to drawings and project requirements within 24 hours, including initial manufacturability feedback.
