Test and Acceptance of Incoming Goods

All incoming goods are subject to testing. This ensures that incoming products conform to specified requirements. Goods which have not been tested are not released for production. Goods which fail the testing in any way are rejected and returned to the supplier.

In-Process Inspection and Testing

The quality control standards require that tests and inspections be carried out before and during production. At the start of production all quality-relevant data is checked by the quality assurance department. Preproduction samples are tested by the laboratory technicians for proper surface finish and dimensional accuracy.

The data from the extrusion and injection molding machines are cross-checked with the actual pipe dimensions and the materials are released for production only if optimal test results are achieved. These tests are carried out at the start of each production series to ensure perfect quality.

Process Control

Ultrasonic measurement and process data recording in the field of extrusion are only two examples of Aquatherm’s extensive quality control process. This equipment allows for constant observation and control of production. 

Ultrasonic waves automatically measure and report any deviations in tolerance to the cutting device on the extrusion machine so that the sizing controls can automatically isolate a substandard product. This ensures that only perfect quality products are packed and stored. All data received during production is analyzed in detail.
