Maintaining consistent quality under constant, verified conditions with defined and documented processes is and always has been a requirement of our production, as the final products must be reproducible and flawless. We have been complying with the requirements of DIN ISO 9001 certification since 1998.
When moving to our new production facility, we implemented building and production technology according to the latest and highest standards. This allowed us to successfully meet the requirements for and obtain ISO 22000 certification for food safety management systems in 2009.
In addition to the DIN ISO 50001 certification (energy management) obtained in 2014, H&K Müller has also been certified according to the ISCC Plus Standard since 2021.
Since 2021, H&K Müller has been certified according to the standards of the "International Sustainability and Carbon Certification System" (ISCC). The certification certifies H&K Müller as a company that it is part of a socially, ecologically and economically sustainable value and supply chain system on a mass balance basis. In addition to the sourcing and processing of sustainable plastic materials, certification according to the ISCC Plus standard also guarantees the complete traceability of sustainable plastics, from delivery through injection moulding production to the delivered end product.
H&K Müller established a quality-management system that encompasses all stages of production along its own value chain back in 1998, when it was certified according to DIN EN ISO 9001 for the first time. In addition to standardised inspection and production-monitoring procedures, this QM system also features product traceability with batch purity. To ensure high and consistent product and process quality, H&K Müller conducts ongoing inspection and review of system-relevant key performance indicators (KPIs).
A major component of our company policies is to sensitise our employees to H&K Müller’s quality philosophy.
We are fully committed to meeting our customers’ quality requirements. We are also constantly striving to improve our own understanding of quality by optimising and standardising all processes along the value chain. This includes regularly evaluating system-relevant sub-suppliers, as well as requesting and reviewing their certificates to ensure a high-quality supply chain.
Thanks to our new production facility in Engelskirchen, we have been certified according to DIN EN ISO 22000 (food safety) since 2009. By setting up, continuously maintaining, optimising and documenting our own HACCP system, we fulfil the highest requirements of food safety. H&K Müller meets the same HACCP guidelines that apply to food-processing companies. These requirements are not only fulfilled for the entire production process at H&K Müller, but also throughout the entire supply process of purchased goods that come into direct contact with the products. H&K Müller continuously monitors the suppliers to ensure that these requirements are upheld.
Production at H&K Müller is subject to strict hygiene regulations. To this end, employees wear hairnets and H&K Müller-issued HACCP clothing without open pockets, buttons or rivets in addition to disinfecting their hands before entering the production facility, which features filtered and conditioned air, and where food and other foreign objects like jewellery are strictly forbidden. In addition to these measures, our employees are regularly sensitised to this topic through the regular and intensive implementation of additional measures.
Only authorised individuals may access our company grounds, which are also looked after by a pest control service.
All of our products are sent to our customers in dust- and dirt-proof packaging.
Through ongoing risk analysis and process optimisation, we always strive to offer the best possible quality.
H&K Müller has been certified according to DIN EN ISO 50001 (energy management) since 2014. This encompasses a detailed record of all energy sources and energy-consuming equipment, as well as the allocation of energy via a smart, digital electricity meter. We continuously evaluate the energy efficiency of our machinery, equipment, process and activities.
Energy efficiency is a deciding factor when acquiring new equipment that consumes electricity. Moreover, to tap potential for improvement, we conduct detailed peak-load evaluations and regularly analyse all primary energy consumers.
By sensitising and regularly training our employees when implementing energy-saving measures, we aim to tap additional potential for optimisation.
