Lerner Molded Plastics is a custom manufacturer providing plastic injection molding solutions for customers across a wide range of industries. From concept through production, we work with businesses that require dependable manufacturing, consistent quality, and parts built to precise specifications. Whether your project involves standard components or large molded products, our team has the equipment, engineering support, and production capabilities to deliver reliable results. Every project is built around your design requirements, giving you a plastic injection molding service focused on performance, efficiency, and long-term value.

A successful molding project starts with the right manufacturing partner. As experienced injection molding manufacturers, we provide custom production backed by modern equipment, quality tooling, and efficient manufacturing processes. Our capabilities support projects ranging from prototype quantities to high-volume production while maintaining consistent part quality throughout every run.
Our plastic injection molding service includes engineering support, mold development, production, finishing, and assembly options to simplify your supply chain. We process a wide selection of thermoplastic materials to match your product’s performance requirements, allowing customers to choose the material that best fits their application instead of limiting them to standard options.
Whether you need components for automotive, industrial equipment, consumer products, construction, medical, or OEM applications, we manufacture parts built for your exact specifications.
Large molded components demand specialized equipment and production experience. Lerner Molded Plastics offers large part injection molding capabilities that support oversized parts without sacrificing accuracy or production efficiency. With presses capable of handling up to 3,000 tons of clamping force and large shot capacities, we manufacture components that many injection molding manufacturers cannot accommodate.
Our production process is built for customers requiring injection molding large parts for demanding applications. From custom tooling through final production, we focus on producing repeatable results while meeting the size, strength, and performance requirements of every project.
Benefits of our large part injection molding capabilities include:
If your product requires large custom plastic components, our team works closely with you to move efficiently from design approval to production without unnecessary delays.
ABS remains one of the most widely used materials for custom plastic components because it combines strength, impact resistance, and dimensional stability. Lerner Molded Plastics provides precision ABS injection molding for customers that require consistent, repeatable parts with dependable performance.
Our manufacturing process supports detailed part geometries while maintaining tight tolerances throughout production. ABS is commonly selected for automotive components, consumer products, industrial equipment, and other applications where durability and appearance matter. Combined with our custom tooling and production capabilities, ABS allows us to manufacture parts that perform consistently from the first production run through the last.
Although ABS is a popular material, we also process many other engineering-grade plastics based on your project requirements, allowing you to select the material that best supports your application.

Quality is built into every stage of production. Our manufacturing processes are supported by ISO-certified quality systems that help maintain consistency throughout tooling, molding, inspection, and production. Every project follows established procedures that focus on dimensional accuracy, repeatability, and dependable performance.
Our engineering and production teams work together to identify manufacturing requirements early, helping reduce production issues before full-scale manufacturing begins. This approach supports consistent results across prototype runs as well as long-term production programs, giving customers confidence that every part meets the required specifications.
Whether you need a dependable plastic injection molding service for standard components or require expertise in large part injection molding, Lerner Molded Plastics is ready to support your project. Our team combines engineering experience, advanced manufacturing capabilities, and custom production solutions to help you bring quality plastic components to market efficiently.
