Lewis Plastics provides more than plastic injection molding capacity. Our technical knowledge, hands-on experience, and value-added services support projects from concept through delivery. Customers rely on us to manage complexity, maintain quality, and keep production moving.
Disciplined processes, defined quality systems, and experienced teams support consistent results across every project. ISO 9001:2015 certification and a focus on continuous improvement help ensure accuracy, repeatability, and dependable performance from first article through production.
Our engineering team works with customers at the start of development to improve manufacturability, reduce costs, and optimize part performance. Services include product development support, mold flow analysis, and CAD design across multiple platforms. In-house tooling capabilities cover new builds, maintenance, and repair.
Complete parts often require more than molding alone. Lewis Plastics performs finishing, decorating, and assembly processes that transform molded components into application-ready products. Services such as ultrasonic welding, pad printing, and machining let customers consolidate multiple steps under one injection molding supplier, reducing coordination and turnaround time.
Every project is backed by ISO 9001:2015 certification and supported by a climate-controlled inspection lab. Processes include dimensional layouts, ISIR, PPAP, FAI, SPC, and advanced analysis to maintain accuracy and consistency.
Reliable supply requires more than production capacity; it takes planning, storage, and timing. Lewis Plastics offers KanBan, JIT, consignment, and vendor-managed inventory programs that align with each customer’s needs. With a 91,000-square-foot facility and a central U.S. location, we operate as a responsive injection molding supplier capable of managing long-term programs efficiently.
Lewis Plastics combines expertise, equipment, and service to keep projects on schedule and built to specification.
