Reducing embedded labor hours lies in reducing the number of screws! Cost reduction through claw tightening.
The number of screws is proportional to the assembly labor, and reducing the number of screws is one way to achieve this; by focusing on claw tightening, we aim to reduce sheet metal processing and assembly labor to lower costs.
The number of screws is proportional to the assembly labor, and this is a method to achieve cost reduction by tackling this aspect. Even with a small production lot, there are benefits from repeat production and using multiple parts per unit. ■ There are assembly tools for both rivets and screws. Assembly with rivets may seem similar to screwing, but the difference lies in the fact that rivets are set in one go, while screws require multiple turns for assembly, resulting in a time difference. ■ Method using claw tightening: The assembly is completed at the point of alignment and incorporation. When two parts are aligned and screwed together, or when rivets are aligned, the alignment and incorporation by claws are completed at that point, which means that the subsequent time for screwing or riveting is eliminated, leading to significant time savings. ■ The key point is to design claw stops of the same shape when there are multiple uses of the same shape or equivalent parts.

basic information
We explain examples of methods for assembling sheet metal parts, such as screw fastening, riveting, and claw fastening, allowing for the selection of each method based on its respective advantages and disadvantages. The claw fastening method, which enables assembly improvements even in small lot production units without the need for optimization typically reserved for mass production, is something we would like to actively promote according to the shape. ■Point: Not only processing optimization but also assembly optimization significantly contributes to cost reduction.
