Chemical etching is among the best processing methods that many industries in the world use in the manufacture of business components, parts, and various industrial products around the world. Qualitetch is one of the established industries that have invested heavily in the chemical etching process to ensure that customers get quality products that are long-lasting and reliable in performance.
However, how does chemical etching work? The majority of people tend to ask themselves this question so that they can have a clear understanding of how their products are produced. It’s good to know the processes that are involved in the production of parts and business components so that you can understand how to safeguard them from all sorts of dangers.
As part of customer service, qualitetch is openly providing such information to its clients to ensure we have a long-lasting business relationship that is productive and transparent. Let’s now how a quick look at how chemical etching works.
Chemical etching is a four-step process, namely metal cleaning, preparation, etching, and resist.
Metal cleaning is the initial step involved in this process. Cleaning is a very vital process that ensures the metals used are from impurities. Clean metals make the manufacturing process easier while enhancing the production of quality components. The ores are usually passed through a cleaning reservoir containing strong alkaline and acid solutions which absorb all sorts of impurities. These metals are then rinsed before they are printed, laminated, and developed. Clean metals will always blend well with chemicals and finishing materials.
Secondly, the metals and them heated by photosensitive resist that contains UV radiations. The metal sheets are heated on both sides using heated metal rollers to remove excess and delicate metal parts before they are etched. This process ensures that only pure and robust metals are used in the manufacturing process. This guarantees all customers of getting durable and quality components.
Thirdly, the prepared metals are now passed through a system containing chemical washers. Many industries use different chemical washers, but qualitetch uses the most effective of all, and that is ferric chloride. This is the primary etchant substance that is used by qualitetch experts. Ferric chloride attacks the UV resist free metals sheets.
It’s here that the metals are passed through a series of conveyors which are big enough to hold various metal sheets regardless of their design and size. This is an efficient system that allows qualitetch to work on the customer’s orders wishing a short time.
Both sophisticated and intricate designs can be produced easily in high precision without tampering with their designs and quality. The acid is specifically meant to provide burr-free components and build the required stress through the production process.
Finally, the etched components and parts are then placed on mesh holders then taken through a stripping pillage chamber which strips the photoresist, thereby leaving behind the base metal that is suitable for work. The qualitetch inspections team analyses the etched metals and gives a confirmation report that qualifies the quality of the product formed.
