About Koushin Equipment Co., Ltd.
Koushin Equipment Co., Ltd. has a factory in Kishiwada City, Osaka Prefecture, and manufactures air conditioning and smoke exhaust ducts. Since relocating the factory in 2018, the factory floor area has been expanded and equipment has been actively updated, so it is now possible to accept orders for large-scale projects (ducts over 5m). At the same time, the company is also working to improve the efficiency of its internal operations. Until now, craftsmen at the factory were responsible for checking the specifications of ordered items and checking order forms, but by being able to complete the work in the office, the time required for checking has been reduced and efficiency has been improved. By conducting study sessions and tests in-house regarding duct specifications and manufacturing methods, it has become possible for anyone answering the phone to provide sufficient information, and customer satisfaction and trust have increased.
In addition, the knowledge and skills of duct manufacturing are also passed down through the Kinki Duct Sheet Metal Technician Association. They provide support to those involved with ducts, such as providing training for foreign workers, whose numbers have been increasing in recent years, training for young workers to improve their skills, and visiting classes at technical high schools.

Reason for introducing the spot welding machine DALEX3328
■Products used
Spot welding machine DALEX3328 type
The idea came from the desire to switch from riveting to welding to reduce the number of steps required to connect ducts. Previously, metals were joined using rivets, but this required a lot of work: drilling holes in the base material, inserting the rivet, fixing with a riveter, and then coating. The DALEX spot welder was considered because it is strong at welding dissimilar metals and is widely used in duct manufacturing.
He said that he had compared our welding machine with other companies', but that the fact that we carefully listened to his needs and made suggestions to him encouraged him to make the purchase.

Benefits of introducing the spot welding machine DALEX3328
■ Usage
Connection between duct base materials, reinforcement of ducts
■ Advantages
Shortened delivery time by reducing the labor required for duct connection
In duct manufacturing, dissimilar metals are often connected to reduce product weight, cut costs, and improve performance. Previously, large ducts required processes such as drilling holes for riveting, inserting rivets, securing with a riveter, and coating, in as many as 60 locations. However, since introducing the DALEX3328, the process has been reduced to one, and work that previouslytook one to two weekscan now be completed in approximately three days. The improved manufacturing capabilities have enabled shorter delivery times, which has increased customer trust, and the company says another major benefit is that it can now receive orders for complex shapes and large items over 5 meters in length.

■How to use the spot welding machine DALEX3328
The gun can be hung from the ceiling or a rotating arm for hanging.
Koushin Equipment Co., Ltd. is currently focusing on capital investments using subsidies and grants. They are working towards the goal of smoothing out not only the manufacturing process but also the overall business, and completing what previously took 10 man-hours in half the time, just 5 man-hours. They plan to use the saved man-hours to other departments and to allocate them to education and study that they could not do before, in order to address the labor shortage that the industry will face in the future.
We will continue to do our best to help Koushin Equipment Co., Ltd. in any way we can, however small our contribution may be, by providing suggestions on welding machines and providing after-sales support.
