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

    Maximize Manufacturing High-Quality

    Metal Fabrication Quality Control

    At Supro MFG, we have a professional quality control team, an experienced QC team and a scientific quality control process that is an integral part of the process to ensure that products are fully inspected and meet specified technical standards and that the source of defective products can be traced at any time, which is the most important task before they leave the factory.

    The first quality inspection of each manufactured and finished product is carried out during the metal fabrication process, with a 10% sampling rate and detailed data recorded, and this process continues throughout the manufacturing process.

    We regularly maintain and calibrate our inspection tools and equipment, which are the basis for smooth QC work, and we take care of them as if they were our employees.

    It is worth mentioning that we can undertake QA (Quality Assurance) of products, using our extensive manufacturing experience to anticipate all risks before the product is manufactured, and by working closely with the QC team to ensure that the product meets the necessary tolerances and quality standards.

    Quality Control Objectives

    -  Produces highly satisfied customers

    -  Consistency in production quality

    -  Meets accurate specifications

    Quality Control Documents

    -  First article inspection report

    -  First article inspection verification
