Jamcor/SJS Products provides advanced CNC machining services that support the development and production of high-performance and complex multi-process electronic components and thermal management systems. With capabilities spanning 3-axis, 4-axis, and advanced 5-axis machining centers and multiple head systems, our CNC machining capabilities deliver precision-machined parts that meet the tight tolerances and performance requirements expected by our customers. Our precision CNC machining services are integral for our work within the thermal management sector, allowing our facility to refine die cast components, aluminum extrusions, and other manufacturing processes required for the production of fully integrated thermal systems.

At Jamcor/SJS Products, our CNC machining services and capabilities are optimized to support applications that demand incredible precision, repeatability, and thermal performance characteristics. We regularly machine materials such as 6061-T6 and 6061-T5 aluminum, along with copper, steel, and stainless steel. Using 3, 4, and 5-axis machining centers, we regularly machine heat sinks, cold plates, enclosures, housings, mounting structures, and high-contact surfaces for thermal interface materials. In thermal management applications, even minor deviations in flatness or alignment can impact final performance, which is why tight-tolerance CNC machining is critical to producing structurally sound parts that integrate with molded plastics, stamped parts, and other assembled systems.
At Jamcor/SJS Products, we make a point to support customers from their early-stage prototyping challenges all the way through to final full-scale production runs of complex parts. Our CNC machining centers are optimized for tremendous flexibility, allowing customers quick validation of part designs that quickly transition into production runs without needing to find additional service providers. With our DFM part analysis services, Jamcor/SJS Products can make meaningful recommendations on improving part designs that improve machinability, streamline production, and reduce overall costs. We want to work with customers to determine the most efficient machining strategies to rapidly iterate thermal management systems and electronic components while maintaining consistency from prototyping to production.


The vast majority of jobs that pass through Jamcor/SJS Products require far more than individual machining of complex parts. As a result, we offer customers a full range of secondary services to help further streamline production and deliver finished components that are immediately ready for integration into larger assemblies. These post-machining services include drilling, tapering, bead blasting, anodizing, quality inspection, and assembly services. Our expansive array of machining centers also allows our team to refine components produced through other available services like die casting, extrusion, cold forging, and injection molding. Our collaborative approach ensures that every project benefits from our engineering expertise, manufacturing experience, and exhaustive commitment to quality.
In our decades of experience, you’d be hard-pressed to find an alloy or metal we have not worked with. We frequently machine various aluminum alloys (A380/A360), copper, steel alloys, stainless steel, and other lightweight thermally conductive alloys used regularly in thermal management applications.
Typical tolerances of ±0.005 inches can be achieved, with tighter tolerances possible depending on part geometry and specifications.
