This disc circular screen is made of stainless steel plate by photo etching technology.
Different from punched stainless steel, this etched stainless steel has zero distortion after the hole is made. It is a chemical reaction that happened on the surface of the stainless steel plates.
Micro hole stainless steel filter screen made through this technology is very smooth and flat without any burs.
This chemical perforating way is suitable for those products that need a very high requirement of hole size precisions and beautiful appearance.
METART offers full customized service for these mini-hole stainless steel filter screens.
You can choose either a food-grade 304 stainless steel screen or a higher-end stainless steel 316L marine grade.
Other alloy screens like brass-made perforated screens can be also customized based on the order quantity.
This thickness is normally under 1mm, the hole diameter is normally under 2mm.
We can still produce photo-etched stainless filter screen discs bigger than a 2mm hole, but normally it will be easily achieved by mechanical punching.
The cost of photo etching is much higher than perforating. So, it doesn't make much sense to do the chemical etching instead of punching unless you have special requirements for the screen surface and product outlook.
