Premium Chemically Etched, Laser Cut, and Precision Machined Components — manufactured by the skilled craftsmen of Pentagon EMS and backed by the expanded capabilities of the StenTech Precision Parts Platform.
At Pentagon EMS, precision manufacturing extends far beyond tooling. Backed by the expanded capabilities of the StenTech Precision Parts Division and our associated company AME, we transform complex concepts into high-quality, production-ready components—from rapid prototypes to full-scale manufacturing.
Selecting the right manufacturing process is critical to achieving the best combination of performance, cost, lead time, and manufacturability. Our engineering teams work alongside you from the earliest stages of product development, recommending the most effective solution whether it involves precision CNC machining, chemical etching, laser cutting, or a hybrid manufacturing approach.
Pentagon EMS provides comprehensive CNC machining and precision manufacturing services for customers requiring exceptional quality, rapid turnaround, and responsive engineering support. Our experienced team specializes in CNC horizontal and vertical milling, CNC turning, Swiss machining, complex mechanical assemblies, and CAD design services. Whether you require a prototype, Iow-volume production, or full-scale manufac- turing, we deliver precision-machined components to your exact specifications with the speed, flexibility, and craftsmanship todays industries demand.
Photo etching is a precision subtractive process that uses photo-resist and chemical etchants to produce thin metal parts with simple or complex geometries.

Etched copper parts offer superb electrical and thermal conductivity for electronics, with copper alloys adding strength, corrosion and cost effective precision.
Stainless steel offers clean, accurate etching and natural corrosion resistance through its chromium content, strong, smooth components for many industrial applications.
Aluminum etching is increasing thanks to its weight, strength, conductivity, corrosion resistance, and non-magnetic properties.

Electroforming builds ultra-precise metal parts atom by atom, delivering smooth walls, complex geometry, and exceptional durability demanding applications.
Advanced coatings and polishes enhance durability, corrosion resistance, conductivity, and offering tailored finishes that improve performance and longevity in demanding applications.
We optimize quality, accelerate timelines, reduce costs, and provide custom solutions that simplify design and procurement, protect your brand, and support scalable growth across every stage of production.
When your part design isn't a fit for just one type of manufacturing process, then you need H.E.L.P.
Our two step process of photo etching and laser cutting is the solution for parts with specific requirements that can't be achieved with one process alone. You get all the benefits of photo etching and laser cutting combined!
Ask if this process is the right option for your part requirements.
We can help. As a custom metal parts manufacturer our goal is to provide you with quick solutions and guide you through the process instead of leaving you in the dark. We offer you a clear understanding of the manufacturing process that best suits your specifications and provide fast responses and solutions. We understand the industry needs of our customers, from small engineering firms, tech start-ups, and job shops to medium or large EMS companies and OEMs.
