Decades of hands-on experience in Littleton, MA back everything ETM Manufacturing builds. Whether you need custom fabricated parts built to your exact specifications or complex components machined to tight tolerances, we take the time to understand what’s actually driving your project before we quote it. Transparency, continuous improvement, and on-time delivery aren’t just talking points here, they’re how we’ve kept customers for years. Work with ETM and you get a partner who treats integrity and collaboration as part of the job, not an afterthought, from prototype through production.
Here are our services
Sheet Metal Fabrication
ETM Manufacturing specializes in precision sheet metal fabrication, leveraging a modern 26,000 sq. ft. facility equipped with advanced laser cutters, turret punches, and press brakes. We deliver custom parts ranging from prototype quantities to high-volume production runs for a wide range of industries, including medical, telecommunications, and industrial manufacturing. Our integrated process emphasizes accuracy, quick turnaround, and quality to meet complex design requirements.
These parts often move next into CNC machining for added precision, get reviewed by our engineering team, or head to assembly and finishing for a ready-to-install result, whether you’re still at the prototyping stage or scaling into production.

CNC Machining
Our cnc machining capabilities include multi-axis CNC milling, allowing us to produce intricate, tight-tolerance components with exceptional precision. Supporting both prototyping and production, our machining services complement fabrication by enhancing part functionality and fit, all backed by rigorous quality control.
Most projects don’t stop here. Machined parts frequently pair with fabricated sheet metal parts, get shaped further with engineering team input, and move through assembly services or finishing services, regardless of whether you’re ordering a single prototype or a full production run.

Engineering
The ETM engineering team collaborates closely with customers to optimize designs for manufacturability, cost efficiency, and performance. Our team can also provide design support on new projects without drawings or CAD files. Our support spans from initial concept development and rapid prototyping to detailed production engineering, ensuring seamless transition from design to finished product.
A design review here shapes everything downstream, sheet metal fabrication, machined components, assembly, and finishing, so what starts as a prototype can move into full production without rework.

Assembly
We offer comprehensive assembly services, integrating components such as fasteners, insulation, and hardware with precision-fabricated parts. From sub-assemblies to final product integration, our assembly processes include quality checks and finishing treatments, providing customers with ready-to-install sub-systems or complete products.
We’re often integrating parts we made ourselves: precision-fabricated components and precision machining, guided by engineering input and finished with finishing treatments, so your sub-assembly is ready whether it’s a one-off prototype or part of a larger production order.

Finishing
Partnering with trusted finishing suppliers, ETM facilitates a wide array of surface treatments including powder coating, plating, anodizing, electropolishing, and silk screening. Our finishing services ensure enhanced durability, corrosion resistance, and aesthetic appeal tailored to your product requirements.
A good finish depends on what came before it. That’s why this pairs closely with our fabrication process and machined parts, and can be applied to work supported by engineering guidance and our assembly team, whether you need one finished prototype or an entire production run.

Prototype/Express Projects
In the design phase, when you are looking for a prototyping partner to help work through and test new and evolving designs and need a very small quantity, fast-turn production.
Once a design is validated here, it doesn’t sit still. It typically moves into sheet metal builds, CNC work, assembly, or finishing, with our engineering team staying involved, before scaling into production.

Production
Ongoing delivery of reliable, high-quality production runs with deliveries scheduled to meet demand.
Nothing changes hands when a project reaches this stage. The same fabricated parts, machining capabilities, engineering expertise, assembly work, and finishing options that carried your part through prototyping carry it through here too.
