Chemical Etching is an efficient manufacturing process to create high-precision metal parts in any complex shape and pattern. More often than not — especially during industrial scale production — Chemical Etching is the most cost-effective as well. This is the conclusion we reached after comparing Chemical Etching to 5 other metal fabrication technologies, namely Stamping, EDM, Laser Cutting, CNC, and Water Jetting, in a previous blog.
But cost isn’t the only thing that matters. In this blog, we talk about other factors that need to be taken into consideration to see when Chemical Etching is the best option. To be specific, we will cover the following:
Chemical etching is perfect for producing burr- and stress-free parts with a wide range of materials. Almost any metal can be etched. These include (but are not limited to):
These materials are most commonly used for chemical etching, but other materials might also be suitable for the technique. If you have another type of material in mind, please contact us with your specifications so we can help find out if chemical etching is what you need.
If tight tolerances is a strict requirement for your product, Chemical Etching can be a good option, compared to traditional manufacturing processes.
Tolerances typically seen on chemically etched features is only around +/- 10% of the parts’ thickness. Chemical etching is especially suitable when round holes, sharp edges and straight or profiled edges are desired.
Since the biggest design challenges often involve the smallest and most precise part of your product, it’s important to know the precision of a manufacturing method. With chemical etching, you can go as small as 30 μm, making it one of the most high-precision manufacturing processes.
With chemical etching, you can create ultra smooth burr- and stress-free parts with a high cosmetic finish, which is important for many applications. Chemical etching is especially suitable when round holes, sharp edges and straight or profiled edges are desired.
Challenges us to develop a prototype for you and you will see.
If you need prototypes — and you need them fast — then chemical etching is the way to go. With our favourite subtractive manufacturing method, prototypes can be produced from drawings in a matter of days. Moreover, chemical etching allows you to move from prototyping to industrial scale production almost instantly.
Note: the ability to quickly transit from prototyping to industrial scale production depends on the specific process to set up. Ideally, the majority of their production parameters are already in place from when they created your sample.
