[Processing Example] What is Half Etching?

Partially, a step shape in the thickness direction is created! It is also possible to adjust the depth.

Hirai Precision Industry is a manufacturer that specializes in etching processing. By performing corrosion (etching processing) from both sides of metal plates, we can create shapes such as porous (mesh, filters) and slits, allowing the metal plates to be penetrated as requested. In contrast, by performing corrosion (etching processing) from only one side of the metal plates, we can create step shapes in the thickness direction partially. This processing method is referred to as half-etching. 【Half-Etching Processing Method】 ■ Transfer the shape to be etched on one side, and transfer the shape to prevent etching on the reverse side. ■ Etching progresses from only one side, allowing for processing of the metal while remaining unpenetrated. *For more details, please refer to the PDF document or feel free to contact us.
