Quality control
our zero-defect promise
As an ISO 9001-certified company, we place particular emphasis on quality through rigorous processes:
- Use of statistical methods (machine capabilities: cm, cmk; process capabilities: cp, cpk).
- Meticulous unit inspection and sorting, performed manually under a binocular microscope by experienced technicians to ensure optimum quality.
- Compliance with tight tolerances, particularly in aerospace (down to 0.03 mm, and 0.02 mm for PEEK).
- • Hot and cold part cleaning to ensure the stability of our parts.
Zero defect quality (Zero PPM (Parts Per Million)) is our target, and thanks to 100% inspection by a metrology department equipped with high-end instruments (Keyence systems, surface roughness tester, contour measuring device, height gauge, 3D cameras, etc.), we can guarantee full conformity of all manufactured parts, regardless of their technical requirements or the specific tolerances involved.
Thanks to these state-of-the-art tools combined with the expertise of our skilled technicians, we identify and correct any potential deviations or variations in real-time. This rigor enables us to maintain a high standard of quality for our plastic parts, meeting the strictest standards of demanding sectors and fully satisfying our clients' expectations.
Furthermore, our processes include:
- Deburring and manual polishing, ensuring the perfect finish of our parts.
- Manual sorting of chips for recycling, maximizing their reuse.
By combining flexibility, adaptability and reliability with bespoke customer support, we deliver high-precision solutions tailored to the most demanding markets. Our commitment to quality and innovation makes Minesco a trusted partner for your plastic machining needs.
