Quality

At RKT, quality is more than just a promise, it’s our unwavering commitment. We meticulously design every aspect of our processes to ensure they are valid, stable, and reliable.

From DoE to Live Online Monitoring

Our quality management system certifications exemplify the foundation of our quality systems. During process development, statistical methods (DoE, ProOp) are used to develop optimum, process-safe, and stable parameter settings. The entire process is then validated, including the qualification of tools and equipment. Defined parameters are recorded during each injection process, and critical quality metrics are checked at defined intervals to detect deviations and trends early. Online sensors monitor equipment and environmental conditions, while regular calibration and maintenance ensure validated conditions are maintained. Automated camera vision inspection is incorporated directly on production lines, and cleanrooms underdo regular air particle measurements and contact sampling to manage particulate and microbial contamination. All of this is an example of our commitment to your product quality.

Tailored Quality Parameters

We recognize that each product has specific quality requirements and we implement custom control mechanisms to meet those needs. Our quality department supports early stages of design engineering utilizing advance quality planning, drafts the measurement strategy for needed for volume production, and preforms design Failure Mode and Effects Analysis (FMEA) to recognize and control risk.

Sustainability

Sustainability is integral to high quality and a principle long embraced at RKT. We demonstrated our commitment as early as 2011 by obtaining ISO 14001 certification for environmental management. ISO 50001 certification for energy management soon followed, making us one of the first companies in Germany to receive both credentials.

We constantly explore methods of optimizing energy and resource consumption across our company and processes, regularly launching new initiatives. We are proud to have already implemented more than 100 projects, including heat recovery, converting to LEDs, optimizing our cooling tower, using energy-efficient technology, replacing circulation pumps, and optimizing compressed air consumption.

100% Inspection

There is no room for errors in medical product manufacturing. Our production tolerances and processes are tightly controlled to ensure product function and safety. We perform 100% inspections along our production lines for particularly sensitive products and per client request to ensure processes remain reliable. Depending on product requirement and the process design, quality inspection can be carried out manually during production ramp-up and automatically using cameras at higher volumes.

In addition to final product inspection, we conduct inspect raw materials and incoming material, and conduct in-process audits throughout the production process to maintain consistent quality levels.
