Pre Production Inspection (PPI)

All raw materials , parts and components used to produce your order are carefully sourced, tested and purchased by our own procurement team. Not by any factory itself as they are often suspected of lowering their costs by purchasing substandard materials. We source, test and purchase every single part ourselves.

To ensure traceability along the supply chain, a bill of material (BOM) is set up for every product we develop. The BOM describes all parts, components, materials and the substances they’re made of, including the physical and chemical test requirements before purchasing and using. Before every production our own quality inspection team checks all incoming materials and components according tot he BOM. This way we limit the risk of delays during as well as quality issues after the production.

Pre Production Sample (PP Sample)

Will attests that all engineering, design and specification requirements are rightly understood, accounted for, verified, and recorded. The inspection takes place at factory floor right after the manufacturer starts producing the first mass production samples. A complete, independent, and documented physical and functional inspection process is conducted.

During Production Inspection (DPI)

During every production our own quality team is in the factory to supervise the production and to conduct so called during production inspections (DPI). These inspections allow us to have an idea of the product quality, early in the production cycle. If quality issues are found corrective actions can be taken

After Production Inspection (API)

Once 100% of the ordered quantity is finished our quality inspection team will conduct an after production inspection using the AQL 2.5/ 4.0 method. The Acceptable Quality Limit, or AQL, is a method widely used to measure a production sample to find whether or not the entire production has met the client’s specifications.

We carefully ensure to select random production samples. We inspect each sample and classify the defects into critical, major and minor defects. We use the bill of material as well as the approved pre production sample for these definitions:

• 0% for critical defects (totally unacceptable defects as a user might get harmed, or regulations are not respected).
• 2.5% for major defects (these products would usually not be considered acceptable by the end user).
• 4.0% for minor defects (there is some departure from specifications, but most users would not mind it).
