Laser beams have a very high energy density (power density) and the ability to instantly melt, evaporate, and remove materials such as metals. Our company specializes in "removal processing such as laser cutting and drilling." "Laser drilling" utilizes short pulse lasers that take advantage of the laser's directivity and high power density characteristics to heat, perforate, and evaporate the material's surface, removing the irradiated area and creating holes by dispersing and removing the material. This method offers high processing precision and can handle hard materials such as ceramics, tough materials, and CFRP, which are difficult to process with conventional drilling methods. 【Features】 ■ Capable of drilling hard materials that are difficult to process with conventional drilling methods ■ Higher processing precision compared to traditional methods, accommodating hole diameters from 18μm to 70mm ■ Aspect ratios of hole shapes exceeding 100 are possible ■ Fast drilling speed, capable of drilling 100 holes of 10mm diameter in 1 second in 100μm thick steel ■ In solar cell drilling, it is possible to create 20 to 50 million fine holes per second *For more details, please refer to the PDF document or feel free to contact us.

In recent years, the application of lightweight aluminum alloys has been widely considered for the lightweighting, high-speed, and low-vibration of transportation equipment. However, full adoption has not yet been achieved. The main factors are that, compared to steel, the cost is high, strength is insufficient, and weldability is poor. Therefore, research and development of reliable dissimilar metal joints has been conducted from various perspectives to explore the possibility of using aluminum alloys and steel as hybrid structural components. This technical document summarizes and introduces some of these research results.

The "Half-Split Power Supply Chip" is a product jointly developed with Daiko Engineering based on a unique theory. By improving the chip shape, we have extended the replacement time on the mass production line from 8 hours to 120 hours compared to conventional chips. This product uses a pressure spring to push the chip holder down, lowering the base of the chip and allowing it to rotate. It features a mechanism that ensures the chip is always in contact with the wire for forced current flow. As a result, Joule heating occurs externally to the chip, keeping the tip temperature low, reducing copper softening, and extending its lifespan. 【Features】 ■ Chip lifespan of 40 to 120 hours, which is very long ■ Reusable ■ Stable welding arc (the current point is always a single point) ■ Reduces welding costs (approximately 50% cost reduction annually) ■ Decreased spatter *For more details, please refer to the PDF document or feel free to contact us.
