Injection Molding for Filtration Products

Lewis Plastics partners with filtration manufacturers to deliver dependable injection molding and insert molding solutions that enhance performance and consistency. Our molded components support both air and liquid filtration systems, combining precision engineering with materials designed to handle demanding conditions.

Molded Components That Keep Systems Running

Filtration systems depend on parts that maintain tight seals, withstand pressure, and resist deformation. Lewis Plastics molds housings, end caps, manifolds, and frames that meet these functional requirements with accuracy and repeatability. Customers rely on our custom plastic injection molding services to produce clean, well-fitted components that perform reliably across diverse industrial applications.

When needed, plastic insert molding allows for the integration of mesh, metal, or threaded inserts to create stronger, more efficient assemblies.

Material Knowledge for Demanding Environments

Durability starts with the right resin. Our engineers work with polypropylene, ABS, nylon, and reinforced thermoplastics to ensure chemical resistance, temperature stability, and long-term strength. The team evaluates each material’s flow characteristics and mechanical properties to achieve stable results throughout the injection molding process.

With this level of understanding, Lewis Plastics is an injection molding manufacturer capable of adapting to specialized performance and regulatory needs in the filtration market.

Manufacturing Flexibility and Post-Molding Options

Projects range from short-run prototyping to ongoing production, supported by automation, machining, and assembly capabilities. Our secondary services reduce handling and keep production moving, while KanBan and vendor-managed inventory (VMI) programs simplify logistics for recurring builds.

Consistency Through Quality and Process Control

Every molded component is backed by ISO 9001:2015 certification and verified through dimensional inspection in our climate-controlled lab. Statistical Process Control (SPC) and real-time monitoring help maintain uniformity from part to part. Lewis Plastics delivers the consistency filtration manufacturers need to build systems that perform with precision.

Consistency You Can Rely On

Dependable materials, tight process control, and experienced people make Lewis Plastics a trusted choice for custom injection molding and insert molding manufacturing in the filtration industry.
