A tap is a tool used for threading, and it is a well-known high-efficiency method for creating screw holes. Our equipment is of the rolling type, which expands the pilot hole (internal) to create the valleys of the female thread, gathering the pressed metal between the valleys to form the peaks. At the request of our long-time customers in the home appliance sector, we propose a processing method that does not generate cutting chips, ensuring that electronic components such as circuit boards inside the products are not at risk. Additionally, we offer multi-axis machines capable of inline processing in conjunction with press processing, as well as a variety of machine specifications, allowing us to propose the best cost performance for our customers. 【Processing Capabilities】 ■ Rolling Taps: Standalone and linked with press lines ■ Standards: Supports sizes from M2 to M8 ■ Tap Machine Specifications: Wire-type 21 axes × 2 units, 12 axes, 6 axes, 4 axes, 2 axes × 1 unit each 　　　　　　　　Vertical axis type 40 axes × 1 unit ■ Factory: Urayasu Factory (Chiba) *For more details, please refer to the PDF document or feel free to contact us.

"Riveting processing" is a method that utilizes the plastic deformation of metals and various materials to join and bond parts together. It can solve issues related to combinations of metals that are unsuitable for welding, as well as the joining of painted steel plates that discolor when welded, and various combinations of sheet metal and resin. Our company recommends press riveting or spindle riveting, starting from a proposal that does not use welding for the processing of OA equipment parts. In particular, with press riveting, we can avoid the specific concerns associated with welding, such as contamination from welding spatter and instability due to electrical conditions, which are required during the joining of parts. In the case of our Urayasu factory, we collaborate with mold design to develop various riveting processes based on the setting conditions of molds, not only on flat surfaces but also in box shapes, folded shapes, and more. 【Main Equipment】 ■ Press riveting and spindle riveting for OA equipment parts molds ■ Brake pad grinding and riveting (assembly) ■ Factories: Urayasu Factory (Chiba), Iwatsuki Factory (Saitama) * For more details, please refer to the PDF document or feel free to contact us.

Cathodic electrodeposition coating is a painting method that uses direct current to charge the paint to the positive electrode and the workpiece to the negative electrode, allowing the coating film to adhere. The painting method involves immersing the workpiece in a water-soluble electrodeposition paint for the electrodeposition process. Near the electrodes, the paint undergoes a chemical reaction to become an insoluble resin, enabling the creation of a uniform and highly adhesive coating film, even on complex shapes. 【Electrodeposition Coating Details】 ■ Product Size: W600×D600×H900 (up to 15kg) ■ Paint: Epoxy resin (#80HV black) ■ Film Thickness: 20μm (thickness adjustment is possible) ■ Hardness: 2H or higher ■ Compatible Materials: Cold-rolled steel sheets, hot-rolled steel sheets, electroplated steel sheets, stainless steel, aluminum, etc. ■ Main Components: Automotive parts, agricultural machinery, electrical equipment, industrial machinery, equipment, building materials, steel furniture, etc. ■ Factory: Iwatsuki Factory (Saitama) * For more details, please refer to the PDF document or feel free to contact us.

Electrostatic painting is a method that efficiently adheres paint to the object being painted by using the object as the anode (positive electrode) and the electrostatic painting machine as the cathode (negative electrode), thereby forming an electrostatic field between the two electrodes. It utilizes the charging power of the mist-sprayed paint particles (negative) to attach the paint to the object. The negatively charged paint moves along the electric field lines, allowing it to wrap around not only the front side of the sprayed object but also the sides, inner surfaces, and back, resulting in a uniform coating. This method is widely used in the industrial sector. 【Painting Details】 ■ Product Size: W500×D500×H1500 (up to 15kg) ■ Paint: Acrylic-based / Polyester-based ■ Hybrid resin (according to specified painting specifications and standards) ■ Film Thickness: Approximately 10μ to 50μ ■ Compatible Materials: Cold-rolled steel sheets, hot-rolled steel sheets, electroplated steel sheets, stainless steel, aluminum, etc. ■ Main Components: Automotive parts, agricultural machinery, electrical equipment, industrial machinery, devices, building materials, steel furniture, etc. ■ Factory: Iwatsuki Factory (Saitama) * For more details, please refer to the PDF document or feel free to contact us.

There are various types of printing, including nameplate displays, one of which is called silk printing. Silk printing involves stretching a silk cloth over a printing plate and using a squeegee to push ink through the silk mesh, allowing the ink to be deposited onto the printed material through the gaps in the plate. This method enables a strong expression of the design on the product. Not only can the ink be applied thickly, but it can also be baked and dried to ensure durability and weather resistance. 【Overview】 ■ Processing Technology: Coating and Printing Related ■ Factory: Iwatsuki Factory (Saitama) *For more details, please refer to the PDF document or feel free to contact us.

• Printing/Publishing

Laser marking is a processing method that directly engraves "marks" such as letters and symbols onto the workpiece by altering and melting part of the surface through laser irradiation. It can mark various materials, allowing not only for the direct visual representation of letters and symbols but also for the permanent printing of items such as two-dimensional barcodes. Additionally, it features the ability to freely create high-resolution patterns. Moreover, since almost no waste is generated during processing, it is considered an environmentally friendly method. 【Features】 ■ Compatible materials: Iron, non-ferrous metals, plastics, etc. ■ Shapes: Flat surfaces and curved surfaces (cones, cylinders, etc.) ■ Processing range: Basic range is 160×160mm (By using an X-Y stage and Z-axis movement, printing can be done over a wider area) ■ Step height: Up to 10mm ■ Factory: Iwatsuki Factory (Saitama) *For more details, please refer to the PDF document or feel free to contact us.
