Spencer Leaver established SL Plastics in 1991, to fill a niche in the market for engineering plastics, in particular packaging equipment along with conveyor systems. SLP business philosophy still remains unchanged today with our plastics manufacturing engineers based in Suffolk “that you do not have to be the biggest, to be the best” and this is reflected by the clients we still serve after more than twenty years (AEROFILL– manufacturer of aerosol filling equipment, DAWSONS– manufacturer of liquid filling equipment). All our customers benefit from our specialist plastics knowledge, competence and commitment as we continue to grow operations on the principle of the best value– lowest cost– plastic supplier available within the UK today in these challenging financial times. We provide a single contact from first enquiry through to delivery, and will provide a quotation on most jobs within 24hrs. We will not be surpassed on delivery, and pride ourselves on meeting agreed delivery schedules every single time, understanding that someone is always awaiting our part, and time becomes money for customers that pick subcontractors who deliver late. In this respect we have forged strong ties with the top manufacturers and distributors of engineering plastics throughout the UK, to make sure that we have a wide array of materials available to go straight to machining. We will work with you from initial design, and through production, to ensure that you can benefit from any possible cost savings, whether through choice of material, design or production quantities. With six heavy duty CNC routers, CNC mills and lathes, we have the efficiency and capability to produce prototypes and one off’s to large production runs, with consistent accuracy and quality guaranteed.
