Why should you plastic injection mould your filters?

Filters play a part in many aspects of our day-to-day lives. From switching on the kettle to the filters in your car’s fuel tank and in anti-flood airbricks- filters are everywhere. Filters can produced using many different techniques, so why should you plastic injection mould your filters? Machine-demonstrating-plastic-injection-moulding-filters Filter mesh loaded onto a metal core The different techniques for manufacturing filters include blow moulding, compression moulding, or plastic injection moulding. At BEC Group a filter mesh is loaded onto a metal core, the steel mould tool closes around it, and plastic is injected into the tool and around the filter mesh, encapsulating it in a plastic moulding to create a support frame for the filter. Cost-effective manufacturing Encapsulating filters through plastic injection moulding is a cost-effective way of manufacturing large quantities. Once the initial outlay of a mould tool is paid, individual mouldings are manufactured at very low cost. If the production of the mouldings has a quick cycle time and involves high levels of automation and little physical labour, then this combined with economies of scale can lead to very economic mouldings. Adding multiple cavities to a mould tool means several mouldings can be made at once – reducing cost per part even further. Repeatability and quality Once a steel mould tool is made, hundreds of thousands to millions of mouldings are produced from it. These mouldings will be identical, making for easy high-volume repeatability. 100% checks on every filter produced ensures they meet stringent quality requirements. High and low volume orders At BEC Group production runs can be as large or as small as your order numbers require. Whilst costs per part are lower with high production runs, sometimes you onlu need a small number of parts. BEC are happy to accommodate this both high and low volume orders. Plastic material range A-group-of-BEC-filter-examples A range of BEC Group’s filters BEC Group’s filters are made from a filtration mesh encapsulated by a plastic moulding. The mouldings are made from nylon, polypropylene or polyester due to their chemical stability when filtering water, oil, or air. In environments where a filter can be combines with a seal and gasket, TPE is often used. Typically filter mesh is made from nylon, but stainless steel and bespoke mesh media is also made. This depends upon the application and particulate size requiring filtering. Low waste Plastic injection moulding produces little excess plastic waste, any excess scrap can be re-ground and used again or recycled. As recycled plastics become more commonplace, you can include a percentage of recycled plastic in your filter to improve sustainability.
