Uncompromising Precision

Electronic housings leave no room for variation. At LMC, tight tolerance control is built into our tooling design, process monitoring, and inspection protocols, so variation is caught and corrected before it becomes a problem for your components.

Supporting Your Innovation

Our prototyping capabilities let you test part and tool design before committing to full production. And our DFM process puts our engineers alongside yours at the design stage, giving your component the fastest, most cost-effective path from concept to production.

Efficiency and Capacity

With plenty of production space and a large equipment arrangement, we can help you meet the growing demand for your products. And with advanced capabilities such as progressive die stamping, in-die assembly, and insert molding, we deliver the efficiency you need to make your parts program succeed.

Parts We Produce

Electrical Wire Housings

Electrical wire housings require precise forming across multiple dimensions to ensure wires seat correctly and connections hold under real-world conditions. We produce stamped metal wire housings using progressive die stamping, forming material in multiple directions within a single tool to create the finished part efficiently and consistently. Our work with Emerson on electrical wire housing components is a strong example of how complex multi-form stampings can be produced at volume without sacrificing dimensional accuracy.

Condenser Support Brackets

Structural brackets for electronic and HVAC systems demand consistent dimensional accuracy and repeatable performance across high-volume production runs. We manufacture condenser support brackets using progressive die stamping combined with in-die assembly, performing multiple operations in a single pass to reduce secondary steps and optimize turnaround times. The result is a structurally sound, in-spec bracket produced efficiently at scale.

Plastic Electronic Enclosures and Housings

Electronic enclosures and housings need to protect sensitive components, assemble consistently, and hold their dimensions run after run. We produce injection molded plastic enclosures, covers, and structural housing components using engineering-grade resins suited for the mechanical and thermal demands of electronics applications. DFM review is built into every new program launch to ensure your enclosure design is optimized before tooling is cut.

Insert-Molded Electronic Assemblies

Many electronics components combine metal and plastic into a single finished assembly — contact plates, terminals, connectors, and sensor housings that require precise metal positioning before plastic is molded around them. LMC’s insert molding capabilities handle the full process: precision stamping of the metal component, placement into the mold, and injection molding of the plastic overshell. The result is a single, integrated assembly that eliminates secondary fastening steps and improves structural integrity.

Metal Frames and Structural Components

Metal frames, brackets, and structural components for electronics applications require tight tolerances and consistent material properties across every run. We produce these components using progressive die stamping with in-die tapping and in-die assembly where applicable, keeping secondary operations to a minimum and ensuring your program runs efficiently at volume.

Materials We Work With

Metals

  • Cold-rolled steel
  • Stainless steel
  • Aluminum alloys
  • Copper and copper alloys for electrical contact applications

Engineered Resins and Plastics

  • ABS — widely used for electronics enclosures and structural housings
  • Nylon (PA6, PA66) — for high-strength, heat-resistant electronics applications
  • Polycarbonate (PC) — for impact resistance and optical clarity in electronics covers
  • PC/ABS blends — for housings requiring both strength and processability
  • High-temp resins for applications with elevated thermal requirements

CONCLUSION

Taking Charge of Results

We had been sourcing the metal arms for a sun visor assembly from another supplier, but were running into issues with the sourced parts arriving out of tolerance. Our engineering team decided we could do better in house. We designed and built a metal forming machine to bend the steel rods to shape, implementing a vision system and chemical sensors to catch any imperfections in the finished arms before they proceeded to assembly. This helped us shorten the supply chain for our customer, which in turn produced better quality parts and shorter lead times.

Frequently Asked Questions

Yes. Our prototyping capabilities allow you to test part and tool design before committing to full production, and before investing in tooling. Prototyping is offered alongside our DFM review process to give your component the fastest path from design to production.

Tight tolerance control is built into our tooling design, process monitoring, and inspection protocols. We verify dimensional accuracy continuously throughout production runs, so variation is caught and corrected before it affects your program. For complex multi-form stampings, our engineers design the tooling to hold tolerances across every forming operation.

Electronics contract manufacturing is the outsourced production of metal and plastic components used in electronic devices and equipment. This includes precision metal stampings, injection molded plastic enclosures and housings, insert-molded assemblies that combine metal and plastic, and structural brackets and frames. Contract manufacturers specializing in electronics provide the tooling, production capacity, and quality systems that electronics OEMs need without the capital investment of running a manufacturing facility in-house.

We produce a broad range of electronics components including electrical wire housings, condenser support brackets, plastic enclosures and housings, insert-molded electronic assemblies, and metal frames and structural components. We handle precision metal stamping, injection molding, and insert molding as a single-source supplier.

Electronics contract manufacturing allows OEMs to focus on design, innovation, and bringing products to market faster while leaving the capital investment, tooling expertise, and production management to a dedicated manufacturing partner. Rather than maintaining stamping presses, injection molding machines, and a full quality system in-house, you gain access to established capacity, specialized engineering support, and economies of scale that are difficult to replicate internally. For most electronics companies, contract manufacturing reduces per-part cost, shortens lead times, and eliminates the overhead of running a production facility.
