Should Manufacturers Use Chem Etching Services for Thin Metal Parts?        

Many industries, including aircraft, medical equipment, and electronics, depend on producing accurate thin metal components. These industries demand metal components with precise and consistent dimensions. Choosing the best chem etching services for manufacturing  thin metal parts  is critical for these industries.

Photochemical etching is a subtractive manufacturing process that has gained traction due to its high precision. This technique works well in creating precise thin metal parts since it makes creating pieces with accurate shapes and measurements possible.

What is Photochemical Etching?

Photochemical etching, also known as chem etching, is a technique that employs a photoresist and chemicals to generate a precise design on a metal sheet.

The process begins with the metal substrate being coated with a photoresist substance, then being exposed to light through a mask and developing the image on it. After the image has been developed, the metal is cut, cleaned, covered in a photo-sensitive resist, and printed onto the tool sheets.

Stainless steel, copper, and aluminum are just a few metals that can be etched using the photochemical method. The method can also create pieces with intricate patterns and varied thicknesses. The process is beneficial in making thin metal components.

Benefits of Photochemical Etching

  1. Cost-effective

For producing thin metal parts, photochemical etching may be a more economical alternative to conventional manufacturing processes like stamping and laser cutting. A photochemical etching company does not require expensive tooling or dies, making it an affordable manufacturing approach to thin metal production.

Additionally, the photoresist can be removed, allowing the metal sheet to be reused. As a result, it decreases the amount of material waste, making it a sustainable choice.

  1. High Precision

The level of precision is higher with photo etching services than with typical production methods. The photoresist can be accurately applied to the thin metal sheets, and the mask used during the exposure process guarantees that only the appropriate parts of the metal sheet are etched.

Complex patterns and designs can be produced at a precision level which is impossible with conventional manufacturing techniques.

Photochemical etching produces precise and detailed metal parts with margins of up to +/- 0.001 inches. This isn’t easy to achieve with other manufacturing methods when working with thin metals.

  1. Versatile

One of the main benefits of photochemical etching is its versatility. The method can be used to make parts with various forms and patterns, even intricate ones that are difficult to produce on thin metal sheets.

Industries that demand versatile metal parts include aerospace, medical devices, and electronics. For instance, photochemical etching is used in electronics to create tiny metal components with intricate shapes and patterns, such as connectors and circuit boards.

  1. Short Lead Times

Additionally, photochemical etching offers faster production times. Little setup and tooling time is needed because of the process’s high automation level. As a result, producers can quickly and effectively make vast quantities of parts.

The production times of photochemical etching can be reduced by up to 50% compared to laser cutting, which can take hours to cut a single part.


Photochemical etching is a versatile, highly precise manufacturing method used to produce thin metal parts. This technology combines computer-aided design, photography, chemistry, and metallurgy to produce metal objects with precise shapes and measurements quickly.
