Who are we?
Based in Northern Ireland, and still a family owned business, Denroy Limited is a leading injection moulding manufacturer with over 50 years of experience and expertise in research and technology, design, prototyping, manufacturing and quality assurance, for supplying precision industries such as Medical, Aerospace, Defence, Automotive, Commercial and Brushes.
Founded in 1972 and privately owned by the Rainey family, the group consists of three brands: Denroy, Denman (haircare) and DenPro (medical). Both Max Rainey OBE and Dr John Rainey MBE have been recognised in the Queen’s Honours List for their outstanding contributions to Economic Development in Northern Ireland.
The Denroy Group operates over 2 main sites and recently dramatically increased the overall factory footprint with a new manufacturing facility extension. A new distribution centre was also built as an additional warehousing and materials storage facility.
Our design team works in close partnership with clients to develop initial design concepts or to take existing designs and make them suitable to manufacture via the injection moulding process.
We work with partners in industry to develop new and innovative processes, concepts and components for complex aerospace and defence applications.
Denroy has advanced capabilities in 3D printing thermoplastics. We have SLA and FDM printers and can make parts in various materials and sizes meaning we can cover a huge variety of applications.
With investment plans in place, Denroy continues to increase capacity and capabilities throughout the business, including new machining centres, Engel moulding machines and white-room facility.
Our continuous improvement initiatives, process monitoring equipment and purpose built MRP system help to minimise waste, reduce manufacturing lead times and ensure quality product every time.
Denroy is one of the few companies worldwide to hold the ADS 21st Century Supply Chains Gold Award (SC21 Gold). Other notable accreditations include AS/EN9100, ISO9001, IAQG, BS8555 and EFQM 6 star for organisational performance. When it comes to leadership and management performance, we have also been awarded the Deloitte Best Managed Companies 2019 and received the Diversity Mark.
