Can I get a finishing certificate when my CNC parts are manufactured in China?
• No, Hongsinn does not provide finishing certificates for parts manufactured in China.
• No. All Hongsinn parts will meet Hongsinn manufacturing standards, regardless of country of origin.
• Yes. Customs duties are included in the price of your parts and you will not incur any additional charges.
• All parts manufactured in China are manufactured and inspected according to Hongsinn's manufacturing standards and our inspection and sampling program.
This finish option offers the fastest turnaround time. Visible tool marks may remain on the part surface, along with potential sharp edges and burrs, which can be removed upon request. The surface finish is comparable to a 125μ Ra finish.
