Aiming to further improve product quality, the company was considering introducing a stud welding machine. Until now, when manufacturing signs (box lettering signs), the company had been using a method of fixing bolts with TIG welding. However, TIG welding is prone to distortion due to heat, which can affect the appearance and precision. In addition, a lot of work is required to correct the distortion, which has led to issues in terms of productivity and cost.

In particular, in sign manufacturing, the beauty of the appearance is important, and the effects of distortion can affect the product value itself. To achieve their policy of "We want to stably provide high-quality products at low cost and short delivery times," they were considering introducing a new construction method. They consulted with Tosan Co., Ltd., a dealer with whom they have a regular relationship, who suggested the option of a stud welding machine, which led to the introduction of the machine. Compared to TIG welding, stud welding has less heat impact on the base material, and they were highly praised for its beautiful finish and stable strength.

The features of our stud welding machine were a perfect match for the solution to their challenges of "improving product quality," "improving the efficiency of work processes," and "reducing costs and shortening delivery times," and they ultimately decided to introduce it.

In addition to stud welding machines, cutting machines and clamps are also used.

①Improved quality due to reduced distortion

② The reduction in work time improves the efficiency of the entire work process.

The biggest benefit felt after the introduction is that "heat-induced distortion has been significantly reduced." With the TIG welding method that was used up until now, heat was easily concentrated on the base material, which caused distortion, especially in the bolt area. As a result, it was necessary to carry out correction work on noticeable areas after completion, and it took about 30 minutes to correct one area.

By introducing the stud welding machine, such distortion almost completely disappeared, resulting in improved product quality. Furthermore, the time spent on correction work was reduced, improving overall work efficiency. The reduction in the time spent on each task directly contributes to Akita Metal Industries' emphasis on "short delivery times," enabling them to produce more quickly.

In addition, the stud welding machine is easy to operate, even for unskilled workers. Normally, three workers use it, but since it can be operated by anyone on-site, it has become more flexible in terms of personnel allocation. Even during busy periods or when there is an emergency, there is a system in place that allows someone to immediately start working, which also leads to an improvement in on-site capabilities.

Akita Metal Industry Co., Ltd. will continue to expand the possibilities of manufacturing through the creation of a wide variety of products, such as monuments that will become local landmarks and steel-framed carports that fit into everyday life. While balancing the enhancement of their facilities and further improvement of their technical capabilities, they aim to create products with higher added value, valuing both "quality" and "speed." We will do our best to help them achieve this.
