Quality Control From Incoming Material To Production Release

The inspection and qualification process as documented by the factory, reproduced here without additions.

Inspection Of Incoming Materials

All purchased products that are incorporated into CM final products are subject to a detailed technical quality control inspection. Material certifications are kept on file for all incoming shipments of thermoplastic resins.

New Part Qualification

Before a new part can be released to production it goes through a qualification process that varies in intensity depending on customer requirements engineering complexity and quality constraints. The qualification methods may include some or all of the following.

  • First article inspection.
  • Process capability study.
  • Pre-production runs to produce a limited number of samples.
  • Production part approval process (PPAP).
  • ECN release to production after customer approval.

Production Monitoring And Verification

Throughout the production cycle plastic injection moulded components and assemblies are checked to verify their compliance with all required specifications. Typical verification and inspection processes include dimensional functional and destructive tests.

Measurement And Testing

Our inspection lab is third party and features state of the art equipment to ensure compliance with the most demanding part and assembly specifications and tolerances.

  • Brown and Sharp Microval coordinate measuring machine (CMM) with Quadra-Check 3D software.
  • OGP optical comparator with smart edge detection.
  • Additional standard measuring and testing devices such as calipers micrometers thread and height gauges and surface plates.

Monitoring Of The Quality System

To ensure compliance and continual improvement our quality assurance system is monitored through a variety of techniques as appropriate for a particular process and its importance. These include the following.

  • Conducting internal audits of the quality system.
  • Monitoring trends in corrective and preventive action requests.
  • Analysing product conformity and other quality performance data and trends.
  • Measuring and monitoring customer satisfaction through periodic surveys.

Certification

The company is certified with the ISO 9002S quality control system. Our product specification sheets list CE and WARS. Certification documents are sent on request rather than published here so that your compliance team always reviews the current version.

What This Page Does Not Claim

There are no test reports, customer testimonials, output records or audit certificates published on this page, because the factory's own documentation does not publish them. Anything you need beyond the process above is sent on request, and if we do not hold it we will say so.
