  • Applications and Benefits of Electrochemical Etching

    Most people might be familiar with metal etching as an artistic method, but it is widely used in the industrial setting as well. Electrochemical etching is used in several different industries for a variety of applications. It is especially advantageous for parts that are hard to produce, for small prototype production lots, when it is difficult to obtain required accuracies, and for cost intensive parts due to expensive mold requirements. Measurement instrumentation is one application where metal etching is commonly used. Specifically, metal etching is performed in the production of...

  • Artistry and More

    If you like branching out and finding new ways to manufacture products, a method that is continuously growing in several industries is chemical machining. This method of metal forming is gaining increasing popularity because of its ability to create precision products that are useful in virtually every industries. This useful process is able to eliminate many costs that come along with hard tooling, improves the design flexibility, and can shorten lead times. Chemical machining is also able to eliminate burring and stress problems that frequently occur in traditional methods. Although...

  • The Magic of Chemical Etching

    Science has come so far in the past few hundred years. At one time, designs would all have to be cut or melted into products and parts. Then, in the middle ages, European craftsmen discovered the patterns could be created in their armor by applying acids or chemicals to the products. While it may have appeared as a sort of magic at first, the process has now been further developed today and is becoming a regular occurrence in many industries. It is used by both artists and manufacturers alike, bringing...

  • Chemical Etching: Metals and Acids

    It is not strange for those in heavy industries to be familiar with different types of metal. For those in the metal industries, it is common to be experts at the different types, their characteristics, benefits and disadvantages. Yet, many who are not involved in this industry might not think that being knowledgeable of chemicals is also vitally important. To many, metal working is melting down metals and reforming them, or else perhaps machining them with various tools. Those not involved in the metal industry are probably wondering, how do...

Industry Information

Chemical Etching

Chemical etching, a process also known as chemical milling or acid etching, is a popular subtractive manufacturing process, used to to etch, engrave or cut very intricate or very delicate lines into metal surfaces. Using corrosive bases and acids, industrial metal parts manufacturers with proper knowledge of chemicals and their reactions with specific metals can achieve highly specialized etching with limited mechanical labor. Chemical etching can be used to achieve decorative or artistic finishes, such as engraving in a photo, or it can be used to create finishes for industrial purpose. It can be used to finish all sorts of products, including but not limited to: circuit boards, dies, plaques, printing plates and stencils. The process can be performed on nearly all metals, particularly copper, nickel, brass and steel, as well as most types of glass and silica.

Chemical etching is performed in a number of steps, five to be precise. These steps are: cleaning, masking, scribing, etching and demasking. The first step, cleaning, is a preparatory step by which contaminants like oil, residue, primer coatings and grease are removed so that the surface material will not have any issues with accuracy or depth during etching. To clean surfaces, manufacturers usually either apply a solvent to them, or they immerse whole parts in de-oxidizing solutions or alkaline cleaners. Next, during masking, manufacturers apply a maskant material to the whole of the surface. This way, when it comes time to etch, any surface area covered in this maskant will not be able to be etched, as they are essentially hidden, or “masked.” In order for them to work properly, it is importantly that they adequately adhere the surface on which they are placed. After masking comes the third step, scribing. During scribing, those areas that will be etched are rid of the maskant. The fourth step is etching. Manufacturers achieve etching not by laser drilling or stamping patterns on, but by immersing the piece in a chemical bath. While immersed, the metal of the part and the chemicals of the bath react with one another, causing erosion along the exposed pattern lines. The longer the time a piece spends in a chemical bath, the deeper its etching will be. After etching, a chemically machined part is demasked. This is the process by which both the remaining maskant and the etchant in which the part was just bathed are removed. Typically, this is conducted either simply using cold water or cold water with additives. Sometimes, the part is also put in a deoxidizing bath. Rarely, the chemicals are scraped off by hand.

Maskants are available in a variety of different forms and compositions, and they may also be applied a variety of different ways. Non-conductive liquid chemical maskants, for example, may either be applied via dip masking, during which the part is dipped into an open tank of maskant and then allowed to dry, or flow coating, during which maskant is cascaded over the part. To apply conductive liquid maskants, manufacturers sometimes use electrostatic deposition, which is a process during maskant is sprayed onto the surface of the material. To ensure that the maskant sticks, electrical charges are applied to it as it is sprayed. Sometimes, the maskant is not a liquid chemical, but rather paint or tape that is coated on in a single layer or multiple layers. Also, in the case of photo engraving, the maskant used is a photoresist. Likewise, the by which maskants are removed, scribing, can be performed in a number of different ways. For decorative purposes, for example, manufacturers may remove the maskant by hand with a scribing knife or etching needle. If the project is being undergone is for an industrial purpose, on the other hand, manufacturers will remove maskant using the help of a template or CNC automation. Manufacturers may also engage in a third method called scribe and peel. During scribe and peel, the desired design or pattern is cut into the masking layer, thus revealing areas of the metal part that should be etched. To remove a photoresist, manufacturers must expose the part to a targeted light.

Chemical etching is cost-effective, efficient and requires few tools. It is faster, more accurate and less expensive than comparable operations, such as hand etching and mechanical etching. Note that chemical etching performed on metals is most effective when it is performed on thin materials, like foil or sheet. It can, however, be used with thicker methods.
