Precision Micro Ltd. is a leading industrial technology and manufacturing entity based in the United Kingdom, recognized globally as one of the world's largest and Europe's market-leading supplier of photochemical etching technology. Operating from its state-of-the-art processing plant in Birmingham, the company specializes in the high-volume production of intricate, high-precision metal components that are essential for high-technology industries worldwide.
The company's roots in precision engineering date back to the early 1900s, with a dedicated focus on chemical etching processes since 1962. This extensive heritage positions Precision Micro as a pioneer in the field, setting industry standards for accuracy, repeatability, and the processing of difficult-to-machine metals. Annually, the company is responsible for manufacturing more than 60 million high-precision components, supplying customers across more than 30 countries in Europe, the USA, and beyond.
Core Business: Photo-Chemical Etching
The central service offered by Precision Micro is photochemical etching (also known as chemical etching or metal etching). This manufacturing process is a highly precise method of metal fabrication that uses photoresist and etchant chemicals to remove material and create complex components without the mechanical stresses, burrs, or material degradation associated with traditional metal machining methods like stamping, laser cutting, or punching.
The photo-etching technique is particularly suited for:
* Manufacturing micro-precision parts with extremely complex geometries.
* Achieving features down to the sub-micron level and maintaining high accuracy.
* Working with hard-to-machine, specialty metals and thin-gauge materials (up to 2mm thick) that would otherwise be impractical or too costly to process.
* Producing components that require zero-stress, burr-free edges, which is critical for safety- and mission-critical applications.
The Birmingham facility is accredited to the highest industry benchmarks, including AS 9100 (Aerospace), IATF 16949 (Automotive), and ISO 14001 (Environmental), demonstrating its commitment to quality and compliance across highly regulated sectors.

Additional Manufacturing Services
To provide complete component solutions, Precision Micro integrates its core etching service with an array of secondary, value-added precision processes.
Precision Forming: Manual and semi-automatic forming of etched components using custom or modular tools to create three-dimensional parts. This often includes in-house spot welding for permanent connections.
Heat Treatment: Various services like hardening, tempering, annealing, and normalising are offered to adjust the physical and mechanical properties of the components, such as increasing surface hardness, ductility, or strength.
Surface Finishing: A range of finishing options is available to enhance the component's form and function, including Vapour blasting, Anodising, Electroplating, Chemical blacking, and Chromium nitride.
Electropolishing & Passivation: Processes used to enhance corrosion resistance. Passivation creates a protective metal oxide coating, while electropolishing produces a brighter, smoother surface with improved corrosion resistance.
Advanced Joining: Specialised joining techniques like Diffusion Bonding & Brazing are offered, particularly for multi-layer or complex components like Printed Circuit Heat Exchangers, ensuring strong, homogenous, or versatile bonds.
Hybrid Machining: They utilize Wire Electro Discharge Machining (WEDM) alongside etching to cut conductive materials with high precision and low residual stress, allowing for hybrid manufacturing solutions.
