entagon is firmly focused on sustainability within the manufacturing process of plastic injection moulding. There are several
considered areas when looking at new products, including cutting down waste by the introduction of direct hot tip feed systems or recycling waste back into production at controlled levels. The design for manufacture (DFM) stage is
where we will actively consider the suitability of recycled materials or bio polymers for production as opposed to specified virgin materials. However, given the nature of some of the bespoke technical mouldings that are produced here, the risk of contamination can sometimes be too high for consideration. With advancing technologies there are now a wider range of environmentally friendly thermoplastic options available. Customers will approach us with a specified
grade of thermoplastic suitable for their product which has been researched and sourced by their design team with both environmentally and sustainability considerations. We will still highlight alternatives should we believe there is a comparable and suitable suggestion for the product that meets the needs of its end use. The recycled polymers that the mould shop regularly
processes are recycled Poly Propylene, ABS and Polycarbonate, which currently have a combined annual usage of around 6.5 tonnes per annum. We also look at other elements such as coring out of a product to reduce the volume of plastic used, while ensuring it remains fit for purpose. Pentagon adopts a conscientious approach to
mould tool design with a keen focus on negating the need for waste plastics in processing. Optimal cavitation, utilisation of hot runner systems, minimising waste, improving yields, and optimising the process are all considerations. Through a measured and documented trialling process, our moulding Technicians ensure that all trial settings and its effects are recorded so as not to repeat processing errors causing excess waste at the development phase. Once optimum processing settings are achieved all documentation is held against product records for reference. Should any processing issues manifest in future production runs, we ensure they are documented, and process improvements are implemented. When a customer’s product reaches the final
production stages, our technicians deliver process optimisation to eliminate
production of waste product. Supported by our expansive quality control processes, regular patrol inspections ensure any product that is substandard is picked up at the earliest opportunity and any processing issues are rectified to minimise waste product. Experienced quality inspectors allows us to
operate a concise waste mitigation programme through quality control, continual monitoring and working to reduce scrappage throughout the injection moulding process. Scrap rates are monitored and recorded,
where viable waste product is reground on site and used for the manufacture of company use products. All other waste is disposed of appropriately according to specific regulations. As a UK Manufacturer and supplier to the
transport sector, we recognise our environmental responsibility and that consideration needs to flow through all areas of the business to ensure that we are maximising our sustainability efforts.
