Quality Control Insurance
Protom deeply understands the need for maintaining high quality standards, having worked on complex and technical components with low tolerance. The company is ISO 9001 certified and has established a Quality Management System, which is a vital part of ensuring quality, customer satisfaction, and continuous improvement.
Each part is inspected in-house and some outsourced measuring equipment are leveraged to meet the desired standards. Advanced equipment like Visual Measuring Machines (VMM) and Coordinate Measuring Machine (CMM) are regularly used to keep a strict control over dimensional accuracy.
