Quality management in a closed, efficient process.

Uncompromising quality and innovative products – quality assurance as guiding principle.

Consistent quality orientation is the basis for reliable, safe products and innovative developments. Ensuring and optimizing this along the entire process chain are the core of the Wirthwein Medical quality management that is anchored and standardized in each of our factories. Based on a certified, integrated management system, we meet all requirements of our customers, the regulatory requirements of the test institutes for our clean room processes and the requirements for sustainable, resource-saving production. Each process step is monitored and documented. Simultaneous or subsequent test procedures ensure constant high product quality for every quantity.

Our keys for reliable and reproducible quality:

Employee qualification

We are already forming the basis for the future qualification and specialization of our employees with our in-house training. Regular internal and external further training measures and the annually held safety, GMP, hygiene and clean room training courses provide continuous know-how transfer.

Material quality

The quality of our plastics starts with the specification of our suppliers, clearly defined incoming goods inspections (including raw material retention samples) and ends with the targeted, application-compliant material selection. Regular supplier audits and material tests secure the varietal purity of our thermoplastics.

Qualification and validation

We succeed in achieving efficiency and stability in the process using systematic qualification and validation measures. These include initial sample reports, clearly defined qualifications such as DQ, IQ, OQ and PQ and the execution of fill studies and optimization loops.

High level of automation

Automated handling systems guarantee defined removal and storage of the molded parts from the tool. Semi and completely automated packaging, assembly and test processes minimize wear, tolerance value and error rate.

State-of-the-art measuring technology

On-site, we provide you with a wide range of standardized and product-specific test procedures, e.g. 100% in-line camera inspections, optical quality and dimensional measurements, measuring microscopy, tensile testing machines and 3D coordinates measurement technology.
