We would like to introduce the "ultra-thin molded products" handled by Kōki Kasei Co., Ltd. We have realized a digital camera aperture blade with a minimum thickness of 0.1mm in a single injection molding process. Our company has absolute confidence in the precision of high-precision gears and consistently responds to customer requests from the prototype and development stages through to mass production. 【Features】 ■ Realization of a digital camera aperture blade with a minimum thickness of 0.1mm in a single injection molding process ■ Consistent efforts from the prototype and development stages through to mass production ■ Abundant measurement of products and data accumulation ■ Ultra-precision gear products (N7 level product precision with POM) ■ Simultaneous realization of thickening and high precision through special molding methods ■ High rigidity achieved through appropriate material selection *For more details, please download the PDF or feel free to contact us.

• Contract manufacturing

We would like to introduce the "drum flange" handled by Kōki Kasei Co., Ltd. The drum flange, which is the core of the imaging section of copiers, requires particularly strict coaxiality and roundness, and may also require post-machining after molding to maintain precision. Our products are manufactured in a single process of injection molding. Please feel free to contact us if you have any requests. 【Features】 ■ Ultra-precision gear products (N7 level product precision with POM) ■ Achieves both thickening and high precision simultaneously through a special molding method ■ Responds to high rigidity through appropriate material selection *For more details, please download the PDF or feel free to contact us.

• gear

We would like to introduce the "Heat-Resistant Gears" handled by Kōki Kasei Co., Ltd. The maximum surface temperature of the fixing section of copiers can reach up to 180°C, and super engineering plastics and engineering plastics are used. Our gears are compatible with such materials that have strict precision and molding conditions. Please feel free to contact us if you have any requests. 【Features】 ■ Ultra-precision gear products (N7 level product precision with POM) ■ Achieves thickening and high precision simultaneously through a special molding method ■ Responds to high rigidity through appropriate material selection *For more details, please download the PDF or feel free to contact us.

• gear

We would like to introduce the "High Precision Hasp Gear" handled by Kōki Kasei Co., Ltd. Our product enables the simultaneous enhancement of web thickness (up to 8mm) rigidity and maintenance of gear precision. Furthermore, it is an ultra-precision gear product that also supports high rigidity through the selection of suitable materials. 【Features】 ■ Ultra-precision gear product (N7 level product precision with POM) ■ Achieves thickening and high precision simultaneously through a special molding method ■ Supports high rigidity through appropriate material selection *For more details, please download the PDF or feel free to contact us.

• gear

We would like to introduce the "internal gear" handled by Kōki Kasei Co., Ltd. High-precision internal gears are essential for the accurate operation of planetary gears in internal hub gear systems for bicycles and in gearboxes for wind power generation. We guarantee the same level of precision for gears that are difficult to maintain and measure accuracy in molded processing, just like helical gears and spur gears. 【Features】 ■ Ultra-precision gear products (N7 level product accuracy with POM) ■ Achieves both thickening and high precision simultaneously through a special molding method ■ Responds to high rigidity through appropriate material selection *For more details, please download the PDF or feel free to contact us.
