Jamcor Corporation/SJS Products maintains a deep expertise in plastic injection molding processes and applies these high-volume manufacturing services towards applications in electronic components and thermal management systems. Jamcor/SJS Products supports all customers from the initial injection molding design phases through the tooling, production, and final assembly stages. Although our injection molding services are available as a standalone option, they play a tremendous role in our ability to support the development and production of complex electrical or thermal management systems.

At Jamcor/SJS Products, we’ve spent years honing our plastic injection molding services to best meet our customers' needs. From producing structurally sound plastic parts or those that require additional electrical insulation or environmental protection, Jamcor regularly produces components such as connectors, switches, sockets, housing, enclosures, and other wire management systems.
For our work in the thermal management sector, our injection molding capabilities are a critical support service that is essential for electrically isolating heat-generating components while maintaining correct spacing and alignment between parts. As controlling heat is essential in these applications, plastic parts can direct airflow within enclosures and protect sensitive electronics from environmental exposure.
From original prototypes all the way through final production runs, Jamcor/SJS Products' injection molding services are optimized to accommodate the tight tolerances required for electronics and thermal management systems. With press capacities up to 100 tons and the ability to hold tolerances within ±0.005 inches, Jamcor injection molding helps customers validate part designs early in the development process, which in turn leads to faster iteration and seamless scaling into full-production runs. All tooling can be developed in-house or through our trusted partners, with our experienced team making these decisions based on project specifications, timelines, budgets, and part complexity.
We understand that plastic injection-molded components are only part of larger or more complex assemblies. As such, Jamcor/SJS Products provides a range of secondary and value-added services to help our customers streamline their production workflow and reduce the need for supplemental service providers, complex logistics, and added costs. These services include insert installation, hardware integration, assembly of multi-component systems, additional surface finishing, and exhaustive quality inspection and packaging services. We pride ourselves on working closely with our clients as dedicated partners and believe that our collaborative approach maximizes our experience, engineering knowledge, and dedication to quality.
Our team regularly works with traditional and more complex engineered resins. This list includes but is not limited to ABS, polyethylene, and SABIC-engineered thermoplastics that are selected during the DFM process to offer optimal durability, electrical insulation, and performance in line with customer part specifications.
Typical tolerances of ±0.005 inches can be achieved, depending on part geometry, material, and tooling.
Yes, Jamcor can support both insert molding and overmolding applications. This allows metal components and electronic components to be integrated directly into plastic molded parts.
Injection-molded parts provide structural support, electrical insulation, and airflow management or control within systems that include heat-generating components that need protection.
