Fulfillment of customer wishes has top priority at the STM-Group. In several control cycles, products and materials are inspected for dependability, robustness and expected quality requirements. Certifications, recordings and documentations enable admittance to western markets and ensure a smooth importation from China. Error rates and complaints are reduced to a minimum, thus saving costs and enhancing customer satisfaction.

Traceable from subcontractor to manufacturer to shipment

In regular intervals, each individual workpiece and work material of the manufacturer is registered, traceable and checked as to its quality standards. Thus, production faults and material defects are detected on first appearance and eliminated from future batches. The STM-Group’s numerous loyal customers have relied on our diligence for over 10 years.

Pre Production Inspection (PPI)

The pre-production inspection comprises all must do checks before commencement of production. Our inspector checks if the chosen factory is able to satisfy your requirements concerning the quality, the capacity and the processing time. This inspection guarantees that the materials used conform to the contractual stipulations and correspond with the standards of the target country.

What do we check during the pre-production inspection?

We start be establishing the relationship between the customer and the supplier in order to enable a smooth information exchange – samples, costs, production schedule, internal quality control, raw materials and other factors relevant to the smooth processing of your order.

The added value of pre-production inspection:
Before the actual start of production our inspectors perform spot checks of raw materials, components and the supplies to be used in production. This helps the customer to countercheck if the factory has ordered the correct materials and components. Often production faults arise due to language differences – this, too, can be prevented by a “PPI”.

The main contents of this service are:

  • Optimal preparation before production starts
  • Safeguarding the service according to requirements and specifications (material, colors etc.)
  • Providing all relevant information before bulk production
  • Arrangements for error corrections
  • The factory is prepared for your order
  • Avoid unexpected delays and costs

During Production Inspection (DPI)

As soon as at least 20 % to 50 % of the products have come off the production line, our inspectors can be on-site to check them for possible deficiencies or deviations from quality parameters and to continue accompanying the process in order to ensure that such deviations are eliminated in the subsequent production process. This check comprises all aspects of a quality inspection carried out according to AQL standards: quality of workmanship, raw materials, product appearance, weight control, combination of functionalities, dimensions, supplies, labelling and logos, packaging materials, wrappings and other special requirements depending on product specifications. Process inspection also covers work in process and compliance with the original production planning. After each inspection you immediately receive a complete and comprehensive report together with pictures, commentaries and feedback. This report enables you either to accept or reject a product.

Why during-production inspection?
During-production inspections keep you informed, at all times, about all circumstances concerning your order. Thus, you can intervene promptly if deficiencies appear. In addition, we check the actual production quantity in order to allow you to ship your products smoothly and without delays.

Pre Shipment Inspection (PSI)

The „Pre-shipment Inspection“ (PSI) before shipment of products is also known as final spot check. It is carried out when 100 % of the products are finished and at least 80 % of the export cartons have been packed. During the inspection our auditors select spot checks for sampling according to AQL standards.

Defect Sorting Service

During this procedure as much deficient merchandise as possible is sorted out (specific deficiencies, functional problems or packaging errors, etc.). Further inspections are not performed by this service.

The added value of a „Defect Sorting Service“
