[Introduction to Sheet Metal Processing Technology] A simple method for adding holes to finished products.
I will introduce a solution to the problem that requires drilling after completion.
Such issues arise when the position and number of holes required for electrical wiring differ based on the installation location and intended use, or when additional holes are needed during installation. If the required positions and number of holes are known in advance, they can be accommodated with custom design. However, if additional holes are needed after completion and drilling must be done from scratch, it can be labor-intensive and may risk damaging the product. By anticipating the need for several holes and processing them in advance through slit or knockout processing, it is possible to reduce labor costs and thus lower overall costs.

basic information
**Introduction to Slitting and Knockout Processing** - Slitting processing refers to a method of creating circular slits (gaps) using laser cutting, as shown in the diagram. After completion, joints (connections) are twisted by hand to create holes. This processing method does not require special molds, allowing for cost-effective processing. It is a commonly used method in our company for producing prototypes. - Knockout processing involves using a knockout mold to press and create holes while leaving the waste material on the product, as illustrated in the diagram. After completion, the waste material is struck with tools to create holes. This processing method requires special molds. Our company possesses several types of knockout molds, but if there is no mold that fits the required hole size, it may need to be purchased, making it potentially expensive. Compared to slitting processing, the processing time is significantly shorter, making it a frequently used method in our company for mass production.

**Advantages and Disadvantages of Slitting and Knockout Processing** - **Advantages of Slitting Processing**: It allows for easy adjustment of strength based on the width and number of joints. (Can be easily removed by hand or may require tools, etc.) - **Disadvantages of Slitting Processing**: There are gaps even if holes are not made. If holes are made, burrs (from threading) remain. - **Advantages of Knockout Processing**: There are no gaps when holes are not made, and it has strength. - **Disadvantages of Knockout Processing**: There can be unevenness when holes are not made. Tools are required when making holes (such as a hammer). By considering these disadvantages and selecting a processing method that does not have an impact, it is possible to easily create the necessary holes during installation and other times. Utilizing our proud sheet metal technology and our integrated production system that covers everything from design to installation, we consider the most suitable processing methods for each product and provide satisfaction to our customers.
