HEHUA FAQ

Trust Reliability

Years of export experience to global markets, proving our reliability in quality, logistics, and compliance.

Certified quality management and standardized production ensure reliable and repeatable results for every order.

What tolerances can you achieve?

Our standard tolerance for CNC machining is DIN-2768-1-f (fine)or +/-0.01mm. For high-precision requirements, we can achieve tolerances as tight as +/-0.005mm depending on the geometry and material.

What surface finishes do you offer?

We provide one-stop surface treatment services, including: As-machined (De-burred) Sandblasting Anodizing (Type ll Type III)Polishing Mirror Polishing Powder Coating Painting Laser Engraving (Logo/Text)

How fast can I get a quote?

Send us your 3D files (STEP/IGES) and 2D drawings (PDF). Our engineering team will analyze them and provide a detailed quote within 6-12 hours.

What is your typical lead time?

Prototypes: 3-7 days Production 10-20 days We also offer an Expedited Service for urgent projects.

Do you provide samples before mass production?

Yes, we always recommend making a pre-production sample for approval. We will send you photos/videos or ship the physical sample to you for verification before running the full batch.

What if the parts do not meet the specifications?

We have a strict Quality Control policy. If the parts do not meet the drawing specifications, we will remake them for free or provide a full refund. We stand behind our quality 100%.
