In sheet metal processing, cutting of metal sheets (trimming, piercing, etc.) is typically done using molds or CO2 laser processing machines. However, with the practical application of fiber lasers, which offer high productivity and energy efficiency, there is a shift from CO2 lasers. While processing with fiber lasers is becoming mainstream for two-dimensional work, there are still very few fiber laser processing machines capable of three-dimensional processing available domestically, making them quite rare. 【Features】 - Suitable for trimming and hole drilling of formed products such as automotive, agricultural machinery, and construction components. - Capable of high-speed and high-precision cutting of difficult materials such as ultra-high-strength steel plates, hot-stamped materials, and thick plates. - High beam focusability allows for a smaller focal diameter, enabling high-speed, high-precision processing with minimal distortion. - Easily handles high-reflective materials and non-ferrous metals such as aluminum, titanium, stainless steel, copper, and brass.

We would like to introduce the "Welding (Assembly)" services we offer. The "CO2/MAG/MIG welding (semi-automatic welding)" automatically feeds a thin wire from the torch tip, creating an arc to melt the wire and the base material together. By using welding robots, we perform stable welding with minimal distortion at high speeds, suitable for joining frames and other components, from thin plates to thick plates. "TIG welding" uses a tungsten (electrode rod) torch to melt and blend the base materials and welding rods. In addition, we also perform "projection welding," "seam welding," "tailored welding," and "brazing (joining)." 【Features】 ■ CO2/MAG/MIG welding (semi-automatic welding) - By using welding robots, we achieve stable welding with minimal distortion at high speeds, suitable for both thin and thick plates. - Mainly used for joining frames and similar components. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Sheet Metal Processing" services. "Shape Correction (Handwork)" allows for precision adjustments of products made from high-strength materials and others, utilizing various tools. "Product Modification (Handwork)" involves using a range of machines and tools based on experience to tailor modifications that meet customer needs. Additionally, after laser processing, unwanted materials such as oxidation films (scales), burrs, and edges are formed on the cut surfaces, which we remove through "Burr Removal Finishing." 【Features】 ■ Shape Correction (Handwork) - Shape correction of products by skilled artisans - Precision adjustments for products made from high-strength materials and others using various tools ■ Product Modification (Handwork) - Tailored modifications based on experience with various machines and tools to meet customer needs ■ Burr Removal Finishing - Finishing work is done carefully by hand, not by machines *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "machining processing" services. "Machining processing," which involves cutting materials such as block materials, allows for high-precision processing of both large and small items, from molds to cutting parts and jig components. "Milling processing" is primarily used for the machining of smaller items such as jig components. Additionally, we offer "lathe processing," which involves cutting round bars and cylindrical shapes. 【Features】 ■ Machining Processing - Capable of processing large items up to 3000×2000 - We have a variety of processing machines, from gantry types to 5-axis machines - By considering appropriate sizes and speeds during processing, we have achieved a maximum monthly production of 150 types *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "bending processing" services we offer. In "V-bending," which allows for linear bending using molds that possess the necessary bending radii, there is no need to prepare new molds unlike in press bending, making it cost-effective. In "pipe and round bar bending," we can accommodate any position and bending radius for round pipes, square pipes, and round bars. Additionally, we offer "roll bending," which bends flat plates into curved shapes like cylinders, and "hemming processing," which creates a "return" on the edges of products. 【Features】 ■ V-bending - We differentiate between press and V-bending based on quantity and shape, providing a more cost-effective and suitable processing method. ■ Pipe and round bar bending - We can handle bending processes that may be rejected by machining companies. - We perform bending using molds and processes like closing the ends of pipes, tailored to the product shape. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "Electrical Discharge Machining (Cutting)" services. By passing an electric current through a wire, we can cut metal like a saw. It is possible to process any conductive material with high precision. While the processing speed is slower than laser machining, it is suitable for cases requiring the processing of thick metals or high precision (0.005mm) that cannot be handled by lasers. 【Features】 ■ Cuts metal like a saw by passing an electric current through a wire ■ Capable of high-precision processing of any conductive material ■ Suitable for processing thick metals and cases requiring high precision (0.005mm) that cannot be handled by lasers *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Laser Processing" services. The "2D (Flat Processing)" allows for cutting metal sheets and other materials into flat shapes, and it is also possible to mark text or symbols on the surface. If you have drawings or CAD data that clearly show the shape, we can process the punching shape immediately without the need to create a mold. Additionally, "3D (Three-Dimensional Processing)" allows for cutting the outer perimeter or drilling holes in three-dimensional shapes. Our state-of-the-art three-dimensional fiber laser can easily handle highly reflective materials such as copper and brass. 【Features】 ■ 2D (Flat Processing) - If you have drawings or CAD data that clearly show the shape, it is possible to process the punching shape immediately without creating a mold. - There are significant cost advantages for small-scale production. ■ 3D (Three-Dimensional Processing) - Over 30 years of accumulated experience and know-how since the introduction of our first machine. - Our three-dimensional fiber laser can easily handle highly reflective materials such as copper and brass. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our company’s "press processing." "Drawing" is a processing method that forms metal sheets into various three-dimensional shapes such as cylinders, cones, rectangular tubes, and pyramids using molds. We have numerous achievements in forming high-strength materials and complex three-dimensional shapes. "Bending" allows for the formation of shapes ranging from linear to those with curves in three-dimensional shapes. Additionally, "shape correction" addresses changes in the shape of existing products (design changes) and precision issues that arise during the trial of mass production molds. 【Features】 ■ Drawing - We have extensive experience in forming deep shapes (deep drawing) and in working with high-strength materials such as ultra-high-tensile steel sheets, as well as complex three-dimensional shapes. ■ Bending - For linear bending processes, we use press brakes, and for bending processes involving three-dimensional shapes, we manufacture press molds, offering production methods tailored to quality and application. *For more details, please refer to the PDF document or feel free to contact us.
