About Us

Knight Plastics Ltd was formed in 1984 by the late Fred Wegener and his wife Marion.

The business grew successfully over the years and in 1999 their sons Colin and Tim became the new directors

Knight Plastics is focussed on being the best manufacturer in the niche markets of magnetic, contacts, panic buttons, call points and other alarm ancillaries. We export worldwide and deal with most major distributors and installers in the UK. A huge investment programme involving continuing research and development of many new lines of contacts, panic buttons, junction box already launched and many new products on the way. Part of our culture is to listen and act on customer’s suggestions, so if you think we are missing anything or need to change any of our products in any way then LET US KNOW. If there is something we can do to improve our range and make life easier for our customers then please e-mail or call us.


All products are manufactured in the UK by our professional and experienced staff. They comply with BS EN ISO 9002. Fire products are made to BS EN 54 Part 11 and Security products to EN50131-1 and PD6662:2004 (including amendments A1 and A2). Magnetic contacts also comply to DD CLC/TS 50131-2-6:2004 . We have a professional and experienced staff
We also still have a small, well run mould shop with 12 machines making our own mouldings for our security products and running contract moulding work for a select group of customers.

As proud custodians of the business built up by our family – WE CARE.

Knight Plastics’ sister company Vitalforce Services has also been set up to handle toolmaking contracts. We have managed the manufacture of hundreds of tools in the last few years thanks to the extensive links we have with both UK and Far East toolmaking. Colin Wegener’s knowledge of tool manufacture and project management has meant that this business has performed remarkably over its first few years of trading. The tool quality, service and speed of manufacture we supply really is excellent as many happy customers in the demanding fields of automotive, teletronic, air management, medical, building and FMCG will testify to.
