Chemical Etching Process Used By Qualitetch for Manufacturing High Precision Parts

Qualitetch is a company that produces various types of high precision metal components for over 25 years by using a chemical etching process. Before knowing more about the products manufactured by Qualitetch you should know what the process of chemical etching is.

What is Chemical Etching?

Chemical etching is a process that is used to manufacture high precision metal components by using the process of subtractive etching. In this process, baths containing chemicals at regulated temperatures are used to remove selective material from the sheet of metal to produce high-quality metal components of desired shape and design. In this way, the chemical etching process can be defined as a process of manufacturing high accuracy parts of metal. It is also known as the process of electrochemical etching and photo etching etc.

The chemical etching process is time and cost-saving process of manufacturing the metal parts with a variety of burr-free flexible designs as compared to other processes of micro-manufacturing like EDM, stamping, laser cutting, water jetting and CNC, etc. It can be used for producing industrial grade as well as a prototype of the high precision metal parts. Qualitetch uses this process for manufacturing a number of high precision products like a variety of motherboards etc.

Working of the chemical etching process

The team of professionals of Qualitetch has to follow a number of steps before using the chemical etching process of the metal sheets. These steps include cleaning of the metal sheet followed by laminating, exposing, developing and etching it. After etching the sheet a stripping process is done before supplying the components to the customers after their rigorous inspection.

The metal sheet used for the chemical etching process is known as a substrate which is first of all laminated with a layer of light or photo-sensitive solution. Selective parts of the metal sheet are then exposed to UV light to develop a positive image of the product design on the sheet. The patterned substrate is then exposed to the chemical etching solution to get the final product by removing the unprotected parts of the metal substrate. In order to get the best results, all the steps are performed under extremely controlled conditions.

Why Qualitetch uses the Chemical Etching process?

Qualitetch uses the chemical etching process to produce high precision metal parts with multiple layers and complex designs. It is the best process for this purpose as the possibility of an error on etched features is +/- 10%. It is specially used for creating sharp edges, profiled or straight edges and round holes as desired in the design of a metal part.

The chemical etching process is an extremely cost-effective and time-saving process for large scale productions as well as for producing prototypes as compared to other modern as well as traditional manufacturing methods like EDM, CNC machining, pressing, stamping, laser cutting, and wire erosion, etc. Qualitetch uses this process for producing prototypes and industrial productions at a rapid rate as it is scalable and involves flexible tooling.
