Customer recognition of us

Ensure high quality products, on time delivery, customer satisfaction, is the purpose of our service.

Excellent work delivered with high efficiency. Overall great services. My project was carried out smoothly and consistently through out the entire duration. Supro MFG truly helped me all the way from designing to shipping even thou it was a relatively small order. Thank you.

Thomas Spencer: Founder & CEO

Great attention to details. For example they asked me if I want matt or shiny powder coat finish, which is something I haven’t considered before. All of these small things adds up and I’m really happy with what I’m paying for.

Lewis Bennet Founder
medical technology company

Great CNC machining capabilities at an affordable cost. I’m glad I found Supro MFG since not many suppliers are willing to take my orders due to the quantity being small. And those who can provide the service are simply charging me too much. I am grateful and happy with the quality from Supro MFG
