Quality management at WSS

Developing high-quality products, manufacturing consistently reliable products and mastering a wide variety of products is a daily challenge for the WSS team. Consistent quality awareness and quality management throughout the entire value chain contribute to our overall performance. From the design and development phase to the final processing of our lock and hardware technology by the customer, all steps are part of this holistic approach to comprehensive quality management. Adapted modules and methods of software-supported quality management cover all of the company’s processes and ensure that new findings are evaluated and products and processes are continuously improved.

WSS quality management guarantees the consistently high quality of WSS products that customers expect from WSS.

DIN EN ISO 9001:2015

Certification in accordance with the new DIN EN ISO 9001:2015 standard documents the status of our quality management and compliance with the latest standards. Regular certification has been part of the company’s philosophy for many years. Continuous learning and mastering new challenges are also key drivers in quality management in order to manufacture products of the required quality and carry out processes with the necessary transparency. The important standard for the company’s quality management, DIN EN ISO 9001:2015, sets the standards for this transparency. The organization of the company, its management systems, the documentation of its processes and their communication are thus bindingly regulated with reference to national (DIN), European (EN) and global (ISO) specifications.

REACH & RoHS

The REACH regulation of the Federal Environment Agency, one of the strictest chemical laws in the world, regulates the handling of chemicals on the European market.

For almost ten years, the regulation has ensured a high level of protection for people and nature. Under the REACH Regulation, manufacturers, importers and users take responsibility for the chemicals they produce and use. Chemicals may only be placed on the market in the EU if they are certified under REACH. The principle of individual responsibility applies. WSS meets these requirements.

Directive 2011/65/EU RoHS in addition to the REACH Regulation regulates the use of hazardous substances in electrical and electronic equipment.

As a downstream user, WSS fulfills all the requirements of the RoHS and REACH regulations. We regularly coordinate with our suppliers and ensure that our suppliers do not use any chemicals that are harmful to people or the environment.

FMEA - Failure Mode and Effects Analysis

As part of its quality management, WSS consistently applies the FMEA method, which is used to analyze concepts and product solution approaches as early as the design and development phase.

Interdisciplinary teams identify potential sources of error in all phases of product development, production planning and application optimization and define solutions to prevent them from occurring.

Factory production control

At all stages of the production process, the conformity of the materials, purchased parts and all internally manufactured preliminary products is checked against the respective specifications on the basis of specific test plans and documented in accordance with DIN ISO 9001:2015. A 100% inspection at the end of the assembly process ensures that all critical segments of our product range meet the defined quality standards for WSS products. In addition to all functional aspects, these standards also include the quality of surfaces, which is checked from a visual and haptic perspective.

Incoming goods inspection

Suppliers are consistently involved in WSS quality management. Cooperation with WSS suppliers and WSS supplier management is characterized by collaboration that begins with product development and the coordination of supplier options, that strives for long-term, close cooperation and that assumes responsibility for overall WSS performance. Regular evaluations of the development of this cooperation and the approaches for its further improvement form a further building block. The daily touchstone of the effectiveness of this cooperation is the coordinated inspection routines of the incoming goods inspection. Only flawless materials and purchased parts pass the incoming goods inspection and are used in WSS products.
