仁張工作所 Product Lineup

The work related to control panels (boxes) has been increasing. Among them, particularly in the field of solar power generation, there are many jobs, often processing large lots of around 100 units. We perform outline cutting with lasers, bend them with a bender, and then the welding process is carried out all at once by a team of 7 to 8 people. In the stud welding process, which is typical for control panels, we maintain quality stability by using automated machines. In the assembly process, we are continuously working on improving productivity by refining the line setup and personnel allocation on a daily basis.

• Contract manufacturing

Using a highly flexible table spot welding machine suitable for assembling the main body of lockers, we rationally assemble lockers of various shapes and sizes. Since our founding, we have been skilled in the manufacturing of box-shaped sheet metal products, and we produce lockers as custom-made and original products. For valuable item lockers, changing room lockers, design lockers, etc., we skillfully combine table spot welding and argon welding to achieve high-quality products. Our know-how in manufacturing the main body and doors has been accumulated over many years, and by integrating line production and cell production, we enhance quality and productivity.

• Contract manufacturing

Our company possesses various welding equipment to select welding methods according to the application. An example is a toolbox that undergoes laser welding after spot welding, achieving both strength and sealing. Since conventional spot welding alone could not meet customer requirements to completely prevent water intrusion from the outside, this case was proposed and prototyped, leading to successful mass production.

• Contract manufacturing

By welding and assembling multiple types of materials, we can achieve both application realization and increased strength. In outdoor boxes designed for security purposes, we have successfully improved product quality by effectively combining materials such as steel and stainless steel (304, 420J2). By selecting the appropriate welding machine according to the application and ensuring that operators acquire the necessary skills, we can achieve a wide range of welding assemblies.

• Contract manufacturing

This is the assembly process of our original product, the "valuable item locker." We handle all processes in-house. Not only for standard products but also for custom-made items, we ensure quality manufacturing. In the final finishing process, we check the product quality based on production instruction documents such as drawings and parts lists before shipping.

• Contract manufacturing

In line with the construction, we respond in a semi-customized manner, and it is often the case that specifications change gradually, so we add design and deployment each time. As shown in the photo, in the welding assembly, by skillfully using jigs and dividing tasks among multiple members, we can not only improve productivity but also reduce variations in quality. We carry out tasks in stages, including temporary welding, main welding, and finishing work.

• Contract manufacturing

Our company conducts sheet metal processing for various box enclosures tailored to specific applications. This includes not only enclosures for control panels but also boxes associated with machinery, FA switch boxes, and enclosures for scientific instruments, among others, with a wide range of uses and purposes. The key to efficiently managing relatively small production units (lots) lies in personnel allocation and the selection of equipment. Our assembly department is systematically working on improving QCD through flexible personnel shifts and a rich lineup of equipment.

• Contract manufacturing

We are currently welding a 1.6 mm thick housing cover. It is required to achieve high precision in the butt joint of the circular part without any leaks. At our company, we primarily use argon welding, while also combining other welding methods to ensure a secure bond. Just like in-house processes, the management of external suppliers (stamped components) is also managed through a centralized production management system.

• Contract manufacturing

The photo shows the welding assembly of large panels for amusement equipment. We select the optimal welding method that meets the required functions, such as arc welding, spot welding, and argon welding, while processing. Our company specializes in manufacturing sheet metal units for panels and enclosures using thin steel plates. We produce approximately 100 large panels, around 1800×800 in size, in team production. The process progresses from the punching stage with a multifunction machine to the bending stage and then to the welding assembly, after which it moves on to the painting stage.

• Contract manufacturing

By mastering the GANMAN (manufactured by Amada), it has become a significant advancement that the previously problematic stud (bolt and nut) attachment work can now be performed reliably. Currently, this equipment is playing a vital role in our company, particularly in sheet metal enclosures for control panels, covers for industrial machinery, and sheet metal parts for amusement devices. By sending the positional information for the stud bolts from the system to the machine, processing can be done simply by retrieving the data.

• Contract manufacturing

We will consider more rational production methods for the mass production of flat panels at each stage. Similar to sheet metal processing, there are increasing improvement proposals from the production site regarding hanging methods and optimal line pitches in the painting process, and we are working towards maintaining a higher level of QCD.

• Contract manufacturing

Recently, there has been an increase in cases where large control panels and distribution boards are introduced in conjunction with the establishment of new production lines during the setup of various factories. While we have a prototype, we gradually add custom-made elements to produce according to the number of units (lots). We process and disassemble large sheet metal enclosures through team welding as we move forward. This time, we produced a lot of 10 to 15 units.

• Contract manufacturing

This is the finishing work for industrial steel boxes. We process them in lots of 200 units. The workflow is established as follows: cutting (laser) → bending → spot welding → powder coating → assembly and packaging. By stabilizing the precision of each process, we achieve aesthetically pleasing products. In the finishing work shown in the photo, 4 to 5 female workers carry out their tasks smoothly and efficiently. 【Example】 ■ Lot: 200 units ■ Process: Cutting (laser) → Bending → Spot welding → Powder coating → Assembly → Packaging ■ Applications/Features: - Mass production of small boxes - Repeated production in response to customer demands with lot settings - Capable of handling large quantities *For more details, please download the materials or contact us.

• Processing Contract

The Z-shaped product in the photo is the base of a tabletop game machine (amusement equipment). It will be painted black afterward and transformed into a product with design appeal. By making improvements during the design development stage, we are pursuing better workability in the bending and welding assembly processes. We have started to break down the welding process into about three parts to enable faster product development.
