Components for Pharmaceutical Applications

We manufacture a range of molded parts used in production, handling, and packaging systems, including caps, closures, trays, containers, and equipment covers. Each component is molded for dimensional accuracy, smooth finishes, and dependable fit. Insert molding capabilities make it possible to integrate metal inserts or functional features that reduce downstream assembly and improve long-term performance.

Material and Process Expertise

Pharmaceutical environments often involve repeated cleaning, exposure to chemicals, or precise dispensing functions. Lewis Plastics works with materials such as polypropylene, polyethylene, ABS, and nylon, selected for their resistance, durability, and stability under load. Our engineers evaluate material performance early in development to ensure that each resin supports both functionality and cost efficiency.

Manufacturing Support and Assembly Services

With presses ranging from 55 to 1,574 tons, Lewis Plastics can accommodate a variety of part sizes and production volumes. Secondary operations such as machining, trimming, ultrasonic welding, and decorating create complete, application-ready components. Packaging, labeling, and warehousing options, including KanBan and vendor-managed inventory (VMI), simplify logistics for recurring production runs.

Quality Systems That Inspire Confidence

All molding programs operate under ISO 9001:2015 certification and are verified in a climate-controlled quality lab. Dimensional layouts, Statistical Process Control (SPC), and detailed inspection records support full traceability.
