Kiya Manufacturing Co., Ltd. proposes a method transition to press processing for cutting, forging, sintering, and FB components. By shaping forms that could not be formed with conventional press processing through press processing, it is possible to improve productivity and reduce costs. This document introduces numerous achievements in method transition, including high-precision shearing, thickening and thinning processing, and three-dimensional shaping processing. [Contents] ■ Method transition proposed by KIYA ■ List of major production equipment ■ Method transition technologies 1 to 13 *For more details, please refer to the PDF document or feel free to contact us.

Our company is engaged in the CFP method "Taper Shape Flattening Process." Compared to conventional methods (general pressing + taper shape cutting), we have achieved a 30% cost reduction by transitioning from cutting processing to cold forging progressive pressing. The taper shape now ensures a surface roughness precision that is twice that of conventional products. 【Features】 ■ Achieved a 30% cost reduction ■ Ensured surface roughness precision equal to or greater than cutting processing ■ Improved strength of the taper shape through the new method *For more details, please refer to the PDF document or feel free to contact us.

Our company is engaged in the CFP method "Irregular Shaping Processing." Compared to conventional methods (sintering + cutting), we have achieved a 25% cost reduction by transitioning from sintering processing to cold forging progressive pressing, and the product's torque strength is more than three times that of sintered products. Additionally, using SPFH540 material improves wear resistance (hardness 23%). 【Features】 ■ 25% cost reduction ■ Product torque strength is more than three times that of sintered products ■ Improved wear resistance (hardness 23%) by using SPFH540 material ■ Capable of increasing thickness from 3.5mm to 11mm (more than three times the thickness) ■ Forming a 4mm serration on the upper part of the stepped shape *For more details, please refer to the PDF document or feel free to contact us.

Our company employs the CFP method "Irregular Shape Flattening Process." Compared to conventional methods (general pressing + irregular shape cutting), we achieve a 20% cost reduction and improved productivity by transitioning from cutting processes to cold forging progressive pressing. Additionally, it allows for the formation of irregular shapes, and there is zero collapse even with thin-walled sections. 【Features】 ■ Achieves a 20% cost reduction ■ Improved productivity ■ New method enables the formation of irregular shapes ■ Zero collapse even with thin-walled sections *For more details, please refer to the PDF materials or feel free to contact us.

Our company offers the CFP method for "high-precision hole punching and blind hole processing." Compared to conventional methods (general pressing + cutting), we have achieved a 25% cost reduction by transitioning from cutting processing to cold forging progressive pressing. We ensure hole punching accuracy equivalent to cutting processing, and the new method allows for the formation of "blind holes." 【Features】 ■ 25% cost reduction ■ Ensured hole punching accuracy equivalent to cutting processing - φ6mm hole: Diameter variation is less than 0.004mm after C-face pressing - φ3mm hole: Diameter variation is less than 0.005mm & pitch error is less than 0.06mm ■ The new method enables the formation of blind holes *For more details, please refer to the PDF document or feel free to contact us.

Our company employs the CFP method "Increased Thickness Burring Processing." Compared to traditional methods (nut welding), products that were previously considered with a material thickness of 5.0mm for screw forming can now be formed with a thickness of 4.0mm. Additionally, the new method achieves high quality by suppressing press draw, increases the number of screw threads, ensures screw strength, and expands the mounting surface. [Features] - Reduction of material volume and integration of nuts - High quality achieved through suppression of press draw with the new method - Increased number of screw threads - Ensured screw strength - Expanded mounting surface *For more details, please refer to the PDF document or feel free to contact us.

Kiya Manufacturing Co., Ltd. has been involved in the construction of Japan's "lifeline" infrastructure, such as communications and power, since its founding in 1946. Marking the 50th anniversary of the company's establishment, we have been conducting research aimed at further enhancing the press technology we have accumulated over the years and developing "cold forging progressive press" technology to reduce costs through changes in manufacturing methods. In the future, even as hollowing out is expected to progress in our country's manufacturing industry, we will focus on manufacturing that cannot be achieved overseas in terms of quality, technology, and cost. We intend to concentrate all our capital on human resource development, research and development, and equipment investment to contribute to strengthening the competitiveness of Japan's manufacturing industry.
