Spencer Leaver formed SL Plastics in 1991, to fill a niche in the market for engineering plastics, particularly packaging equipment and conveyor systems. SLP business philosophy still remains the same 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 shown by the customers we still serve after more than two decades (AEROFILL– manufacturer of aerosol filling equipment, DAWSONS– manufacturer of liquid filling equipment). All our clients benefit from our specialist plastics knowledge, expertise and commitment as we continue to grow operations on the principle of the top value– lowest cost– plastic supplier available within the UK today in these challenging financial times. We give a single contact from first enquiry through to delivery, and will provide a quotation on most jobs just 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 clients that opt for subcontractors who deliver late. In this respect we have forged strong ties with the leading manufacturers and distributors of engineering plastics throughout the UK, to make sure that we have a wide range of materials available to go straight to machining. We will work with you from initial design, and through production, to guarantee that you can benefit from any potential 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 constant accuracy and quality guaranteed.
