Basic Knowledge of Sheet Metal Processing - What is Unit Assembly Processing?

We will introduce knowledge related to sheet metal processing.

"Unit assembly processing" refers to the process of incorporating electrical wiring and circuit boards into a casing (box-like structure) that has been created through precision sheet metal processing, thereby performing mechanical assembly. This requires an understanding of drawings and assembly techniques that differ from those used in precision sheet metal processing, such as electrical wiring diagrams and assembly processing diagrams. At Tubota Technica, we pride ourselves on being a precision sheet metal processing company capable of this unit assembly processing, allowing us to contribute to our customers.
