From high-volume production to complex multi-cavity tooling, we help automotive OEMs and Tier-1 suppliers to meet tight deadlines and stringent quality demands — delivering filters with consistent performance and rapid turnaround.
Domestic & White Goods Filters
Domestic & White Goods Filters
Filters for white goods and home utilities play critical roles in preventing lint and debris in dryers, protecting heating elements in boilers, keeping pumps in working order, maintaining water quality in dishwashers, and enhancing appliance performance overall.
At BEC Group, we design and manufacture precision injection-moulded filters for household appliances and white-goods applications. Our expertise spans filters for washing machines, tumble dryers, dishwashers, boilers, vacuum cleaners, toilets and other domestic systems — all engineered for durability, consistency and performance in high-use environments.
Prospective customers approach BEC for their filters at various stages of the process- some with a similar shaped part, a CAD drawing, or just a concept. From here we can advise on design changes, materials, and mesh types to best suit the design and its application. A tool is then produced to the customers exact specifications- sometimes made up of multiple cavities for high-volume projects. Moulding follows- we can produce tens of thousands of filters a month if required.

Biomedical Filters
Biomedical Filters
Biomedical and pharmaceutical applications rely on filtration components that are precise, reliable, and manufactured to consistently high standards. At BEC Group, we specialise in designing and producing bespoke plastic filters tailored for diagnostics, life sciences, medical devices, pest control and pharmaceutical processes. With decades of injection-moulding and in-house toolmaking experience, we deliver filtration solutions that meet strict industry requirements while offering the flexibility needed for innovative product development.
Our process starts with collaborative design-for-manufacture support. We work closely with clients to select mesh type, micron size and overall geometry. Because we manufacture all tooling on-site, we maintain full control over tolerances, quality, and production timelines—allowing rapid prototyping and seamless scaling to full production.
BEC Group produces filters in a wide range of medical-grade polymers such as PP, PE, nylon, and ABS. We also offer multi-material designs using overmoulding, enabling integration of soft-seal features or complex shapes without secondary assembly. This reduces risk, improves reliability, and simplifies the supply chain—key advantages for regulated medical and pharmaceutical environments.
Our filters are used in biomedical applications such as point-of-care diagnostic cartridges, venting and breather systems, reagent pathways, fluid-control devices, and equipment requiring chemical resistance or pressure stability. Many clients approach us when off-the-shelf filters do not meet performance demands. Whether the challenge involves low-pressure flow accuracy, compact device formats, or specialist chemical compatibility, our engineers develop custom solutions that enhance both function and manufacturability.
Quality assurance is central to our work. We offer contamination-resistant workflows, material traceability, and consistent manufacturing standards to suit the expectations of medical and pharmaceutical manufacturers.
Other Filters
Other Filters
Alongside our more traditional application filters, we also help our customers to produce more niche filters across various industries. We collaborate on the design to optimise it for tooling and injection moulding – advising on materials and testing out options as we move through the process.
We coordinate closely with our customers by understanding their application needs, analysing environmental requirements, and offering expert design support. Through iterative prototyping, material selection, and rigorous testing, we co-create specialised filters that deliver reliable, precise, and cost-effective solutions tailored to each customer’s unique challenges.
Filters we have recently developed for the water sports and biomedical industries have included iteration and testing to find the ideal mesh per the application- including hydrophobic characteristics, micron size, and environmental stability.
For organisations developing new filtration systems or improving existing components, BEC Group provides the technical expertise and manufacturing capability to deliver dependable, high-performance plastic filters, regardless of their application.
Our Mesh
Selecting the appropriate material for a filter project is crucial to its success. Do you need hydrophobic or hydrophilic coatings? Will your filter need to be dust resistant? Would an acoustic mesh be useful? Answers to all these questions and more help us to select the perfect mesh for your filter.
Due to their stability across various chemical and structural environments we typically utilise nylon, polypropylene or polyester for filter encapsulation. Occasionally customers require a more specialised mesh- we work with a variety of different mesh suppliers across the globe, so finding the ideal material for your part is no problem. Stainless steel, pioneering PET depth-media, or even a bespoke mesh developed for your part can be used.
The Process
At BEC Group, our injection moulded filters encapsulate various filter meshes within durable plastic frames designed for their environment. Projects begin with design and tooling, where performance requirements are defined and suitable materials such as nylon, polypropylene, or polyester are selected based on the operating environment, including exposure to water, oil, air, or chemicals.
A steel mould tool is then produced in our in-house toolroom, often with multiple cavities for efficient high-volume production. During moulding, the filter mesh is accurately positioned before molten plastic is injected to secure it within the frame. Secondary operations and quality control checks ensure consistent, high-quality parts.
