Through the combined capabilities of Pentagon EMS, the StenTech Precision Parts Division, and AME, we deliver precision manufacturing solutions from prototype through production. Our integrated capabilities include CNC machining, chemical etching, laser cutting, and precision fabrication, allowing us to select the best process for every application.
We manufacture components from stainless steel, aluminum, copper, brass, titanium, engineering plastics, and specialty alloys including Inconel and molybdenum. Our engineers carefully evaluate material properties, tolerances, performance requirements, and production volumes to optimize quality, lead time, and cost.
From electronics and aerospace to defense, medical, semiconductor, and industrial markets, we provide the engineering expertise and manufacturing flexibility to produce precision components that perform reliably in the most demanding applications.
Our metal stock reflects the most requested materials for photo etched and machined parts, including various tempers and thicknesses. This is not a complete list, so if you do not see a material or metal that you require, please contact us for more information. Our metal supply partners have an excellent delivery response rate.
If we do not have a certain metal thickness in stock, we can "mill down" or chemically etch the metal to your desired thickness. This is one of the key benefits of choosing the chemical etching process. The etching process does not alter the metal properties or flatness, and you will not have to wait for specific mill run stock, which significantly reduces lead times.
The largest sheet of metal we can etch is 24" x 30". However, a one-inch border around the perimeter is necessary to maintain part tolerances, so the largest single part we can actually etch is 23" x 29".
Available in numerous alloys, including 303, 304, 17-7, and 15-5, stainless steel offers exceptional strength, durability, and corrosion resistance. Ideal for industries from aerospace to medical, it often undergoes finishing processes such as passivation or polishing for enhanced performance.
Lightweight, highly machinable, and available in grades like 6061, 7075, and MIC-6. Aluminum is used in aerospace, electronics, and industrial applications for its ductility, corrosion resistance, and thermal conductivity. It is often anodized for added protection and aesthetics.
With a high strength-to-weight ratio and 40% lighter than steel, titanium is essential in aerospace, medical, and high-performance automotive parts. It withstands extreme environments while maintaining structural integrity.
Machined in grades such as C-260, C-360, and C-646, brass offers excellent machinability, corrosion resistance, and durability, making it ideal for bushings, bearings, gears, and fittings.
Used in applications requiring high electrical and thermal conductivity. Grades such as C10100, C11000, and C10200 are machined into busbars, heat exchangers, shielding components, and more.
High-performance plastics like PEEK, HDPE, Delrin, and polycarbonate are machined for industries such as medical, semiconductor, and food processing, offering lightweight, corrosion-resistant alternatives to metals.
Photo etching is a great alternative to other metal fabrication methods such as stamping, laser cutting, wire EDM, and water jet cutting. Unlike these other processes, chemical metal etching can achieve all the following results without compromising the part's function and quality.
No machining heat-affected zones or thermal stress.
Eliminates the need for secondary deburring operations.
Achieves tight dimensional tolerances without compromising part complexity.
Produces smooth, exceptionally even surface finishes.
Every project at Pentagon-EMS (StenTech) is custom-engineered to your exact requirements. Because no two projects are alike, our streamlined quote process helps move you from concept to production quickly, accurately, and with confidence.
