What is chemical etching?

Chemical etching is an etching method that uses a high-pressure chemical syringe to remove material and create a permanently etched image on the metal. A mask or resistor is applied to the material surface and selectively removed by exposing the metal to create the desired image. A conditioning machine benefits from the acidic reaction between the chemical and the material and increases the effect by heating the solution and spraying it at high pressure. The chemical syringe dissolves unprotected metal areas to etch atom-by-atom material for a smooth, burr-free finish.

Advantages of chemical etching

The following are positive aspects of chemical etching :

Low cost, many traditional in comparison, precision metal stamping has a lower production cost per unit, but has a very high cost of tools. This is especially true in cases where complicated parts are produced. In this case, chemical etching is the most economical alternative, especially if you produce a small or medium batch of multi-purpose pieces. On the other hand, for very large quantities for extremely simple pieces, metal stamping would have the advantage.

The properties of the metal remain unchanged.

Another method, such as laser cutting and stamping, changes the characteristics of the metal during the production process. If there is a change in the designated part during the chemical etching process, the prototype can be modified with little trouble and cost. Additional costs may also arise often for the work required to finish the product by stamping.

In addition, metal stamping cannot process sheet that has previously hardened. However, almost all metal can be chemically etched, including copper, brass and stainless steel. While it depends on the engineering of the component, chemical etching can be a very reasonable and cost effective solution. The most important factor is determining the cost is the thickness of the metal.

Burr-free tolerance

Metal stamping often requires more abrasive treatments to remove burrs. Burrs do not exist on components that are produced with chemical etching. In addition, chemical etching will not affect the intrinsic properties of metal parts. For example, metal stamping greatly affect.

Etching can best be done with metals such as molybdenum and titanium. There are many applications for which etching is used.
