Versatile, Reliable, Scalable Production.The cornerstone of modern manufacturing, ideal for high volumes of identical parts. Our process, supported by 90 to 830-ton presses, delivers exceptional consistency and detail for enclosures, components, and consumer goods across all industries.
Create Integrated, Multi-Material Assemblies.Bond plastic to a substrate in a multi-step process to enhance product durability, ergonomics, and value. This technique eliminates secondary assembly, improves seals and grip, and offers vast aesthetic flexibility for a superior end product.
Encapsulate and Protect Critical Components.Permanently embed metal inserts, fasteners, or electronics within a plastic housing during a single molding cycle. This process strengthens assemblies, eliminates post-molding fastening steps, and provides robust environmental protection.
Excel in Extreme and Sensitive Environments.Go beyond traditional plastics with LSR's exceptional flexibility, biocompatibility, and high-temperature resistance. Ideal for producing medical-grade seals, comfortable grips, and durable membranes for automotive and healthcare applications.
Achieve Macro Precision on a Micro Scale.Manufacture intricate, tiny parts with tolerances in the micron range. This advanced process is critical for medical devices, micro-optics, and miniaturized electronics where uncompromising precision and flawless geometry are non-negotiable.
Eliminate Defects in Strong, Lightweight Parts.Perfect for thick-walled components. By injecting pressurized gas into the melt, we create hollow internal structures that prevent sinks and warpage, significantly reduce part weight and material use, and deliver excellent surface finish.
Combine Aesthetics and Function in One Cycle.Integrate two different materials or colors in a single, efficient molding process. This technique enhances product value, ergonomics, and brand differentiation by combining, for example, a rigid substrate with a soft-touch TPE layer without secondary operations.

This project demonstrates how advanced surface finishing, material selection, and supply chain integration enable premium consumer products. LS Manufacturing delivered a high-gloss, scratch-resistant housing with integrated soft-touch grips through two-shot molding, achieving perfect balance, quiet operation, and wireless charging compatibility for a seamless user experience.
Facing strict weight and performance mandates, we engineered a monolithic housing from carbon-fiber reinforced PEEK. The solution replaced a multi-part aluminum assembly, achieving a 60% weight reduction while maintaining structural rigidity and withstanding extreme vibration and thermal cycles during flight testing.
This project required a casing that was both protective and tactile. We utilized overmolding to combine a rigid PC inner structure with a soft TPE outer layer, creating a part that dampens impact, provides secure grip for technicians, and houses sensors safely—all while meeting cleanroom production standards.
For a leading electric vehicle platform, we developed a large-format, glass-filled PP component that integrated mounting, sealing channels, and EMI shielding features. The single molded part replaced a glued and riveted assembly, achieving IP67 protection, reducing weight, and cutting assembly time by 70%.
A manufacturer of industrial mixers needed a sensor housing resistant to aggressive chemicals. We molded the component from PVDF, a high-performance fluoropolymer, and incorporated threaded metal inserts directly during the cycle. The result was a leak-proof, chemically inert housing that withstands years of exposure to acids and solvents.
