Electronics Plastics Manufacturing
Natech Plastics engineers and manufactures plastic injection-molded components and subassemblies for electronics applications. Military communications, medical device, and consumer electronics clients draw upon our comprehensive analysis and testing for design verification and evaluation to build lighter, more durable parts.
Custom Plastic Injection Molding for Electronic Devices
Ruggedized, military-grade electronics must perform reliably in demanding environments. Components must pass strict testing requirements in chemical resistance, heat resistance, high altitude performance, and heavy load. A deep expertise in novel resins is required for metal-to-plastic conversions with extreme requirements.
Natech's Engineers are experts in custom injection molding with high-performance polymers. Over half our output is in ultra-polymers, high performance resins, and engineering-grade resins. With such a high output of engineering-grade polymers, our engineers have built a solid foundation in selecting, processing, and testing novel resins for challenging performance requirements. We process both thermoplastics and thermosets.

Design and Project Management
Design for Manufacture and Assembly (DFMA)
Natech's Engineers offer deep DFMA expertise for ruggedized electronics applications.
Hermetic Sealing – The top and bottom components of a housing must hermetically seal together. Achieving the proper hermetic seal on a highly filled part requires proper weld joint design. Ultrasonic welding is the typical way to seal two halves in electronics. As the glass-fill increases the weldability goes down. If the glass is on the surface, the glass does not melt, so the hermetic seal is very difficult to achieve.
EMI/RFI Shielding – Metal typically shields against EMI/RFI interference while plastics do not. Any interference must to be controlled. Metal, paint, and plating are typically used to achieve this requirement.
Low-Draft and Deep Draw – Some applications require a near 0-degree draft over a 6-inch core.
Extreme Temperature – From a mechanical perspective, cold temperature drops are the limiting factor for plastics in the -40 degree Celsius drop tests. Few resins hold up to this temperature demand.
