At Photofabrication Engineering, Inc. (PEI), we specialize in manufacturing custom etched metal grids with exceptional precision, consistency, and surface quality.
Using our advanced photochemical etching capabilities, we manufacture precision metal grids with straight sidewalls, tight opening sizes, and burr-free surfaces. These grids are engineered to maintain consistent flow, structural integrity, and alignment under even the most demanding operational conditions.
Whether you’re designing components for electron control, RF signal modulation, or medical imaging, we deliver scalable solutions that meet your specifications on time and within budget.
Metal grids are thin, patterned components that serve critical roles in high-performance systems. Used to control electron beams, guide electromagnetic waves, and separate signal pathways, these grids are found in:
These essential components must be manufactured with high dimensional accuracy and smooth surfaces to avoid field disruption, thermal distortion, or misalignment, making photochemically etched grids the clear choice for engineers who prioritize performance and repeatability.
Unlike mechanical methods such as stamping or laser cutting, photochemical etching (PCE) provides exceptional control over geometry without introducing mechanical stress, heat distortion, or burrs. That’s why leading OEMs turn to PEI when quality, lead time, and precision matter most.
Whether you need fine-pitch mesh for an RF filter or multilayer signal routing, our process ensures you receive a custom-etched component that fits your equipment, meets spec, and complies with industry standards.
At PEI, we are materials experts who specialize in etching difficult-to-machine metals with high precision. Our typical thickness range is 0.001″ to 0.010″, with material compatibility across a wide range of alloys.
Metals include:
aluminum, carbon steel, galvanized steel, and expanded metal sheets for broader compatibility
Whether you’re working with light, highly conductive metals or durable, high-density alloys, we have the capabilities to deliver finished components that align with your project’s material requirements and functional demands.
We know how important quality is to your software-controlled systems, sensors, and communications hardware. That’s why PEI maintains a precise, repeatable fabrication process and adheres to stringent quality control at every stage.
Our customers rely on PEI to deliver etched metal grids with exceptional uniformity, integrity, and compatibility, regardless of batch size or complexity.
