E-Fab’s Chemical Blanking Processes and Advantages


Chemical blanking delivers the precise and intricate machining of complex shapes with tight tolerances. Highly accurate and repeatable, it’s the perfect process for manufacturing parts with intricate geometries, thin walls, and fine details.


A more cost-effective alternative to conventional machining methods, such as milling or laser cutting, chemical blanking keeps more money in your pocket, especially for large-scale production runs. Eliminating the need for complex setups, specialized tooling, and extensive machining, chemical blanking can also further reduce production costs by processing multiple parts simultaneously.


As versatile as it is valuable, the chemical blanking process can be applied to a wide range of materials, including metals and alloys. Effective for both conductive and non-conductive materials, the popular process can produce diverse components across various industries.

Stress-free machining

Producing parts with no mechanical stresses, chemical blanking elevates itself above conventional blanking methods that can often introduce residual stresses or alter the material properties. The process is particularly advantageous for materials that can deform or crack during conventional machining.

Burr and micro-crack free

Chemical blanking ensures a smooth surface finish and reduces the need for additional post-processing steps like deburring or polishing, thanks to its ability to avoid generating burrs or micro-cracks on the machined parts.

Material conservation

Due to its subtractive process that selectively removes material, chemical blanking saves you in more ways than one by delivering minimal material wastage. It’s also a more environmentally friendly option compared to other manufacturing processes, with the chemical solutions used able to be recycled.

Complex designs and internal features

Often challenging or impossible using traditional machining methods, Chemical blanking lets you create precise, intricate designs, including internal features like pockets, channels, or recesses.
