The "Lightweight Hollow Shaft" is a product that features a hollow design for long shafts. By hollowing out heavy long shafts, the weight reduction effect is significant. It is also possible to use INV processing through forging, just like solid shafts. We can propose shapes and methods tailored to your needs, such as semi-hollow designs. 【Features】 ■ The method is exclusively forging ■ Weight reduction through hollowing ■ Involute forging ■ L/D ratio of 20 times ■ Proposals for shapes and methods based on applications, such as semi-hollow designs *For more details, please refer to the PDF document or feel free to contact us.

The "Lightweight Hollow Long Bolt" is a hollowed product of long bolts. The manufacturing method is only forging, and it can be rolled even in a hollow thin-walled shape. By hollowing out heavy long products, the weight reduction effect is significant. We are developing applications such as sealing functions, fuel and coolant injection functions through lateral holes, and sensor functions. 【Features】 ■ Manufacturing method is only forging ■ Weight reduction through hollowing ■ Thickness can be adjusted for each part ■ L/D ratio of 25 times ■ Can be rolled even in a hollow thin-walled shape *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study on reducing lead time and costs by converting the manufacturing process from cutting to cold forging. Previously, one side of the spline and the outer shape were processed through cold forging, while the other spline was finished through cutting. By tightening the clearance of the mold, we were able to convert everything to cold forging, achieving a 25% reduction in processing costs and an 80% reduction in lead time. [Results] ■ 25% reduction in processing costs ■ 80% reduction in lead time *For more details, please refer to the external link page or feel free to contact us.

We would like to introduce a case where we achieved cost reduction through cold forging and machining. In conventional processing methods, integrated forming was performed through hot forging, and hole processing for the flange and shaft parts was done as a secondary operation, which took a considerable amount of time. Therefore, we proposed forming through cold forging and machining, successfully achieving significant cost reduction. 【Case Study】 ■Challenge - Hot forging and machining require a lot of time. ■Proposal - Forming through cold forging and machining. *For more details, please refer to the external link page or feel free to contact us.

Cold forging is a method of compressively forming metal materials such as carbon steel, alloy steel, stainless steel, and non-ferrous metals using molds. Cold forged components have the characteristic of higher dimensional accuracy during forming compared to other forged parts. The surface condition is better than that of hot forging and warm forging, so finishing processes may not be necessary. By performing intermediate annealing and lubrication treatment, it becomes possible to precisely forge large products and high-strength materials. 【Features】 ■ Reduced loss from machining ■ Higher accuracy during forming compared to hot forging and warm forging ■ Fiber flow (fibrous structure) is not cut, improving wear resistance *For more details, please refer to the external link page or feel free to contact us.

Forging refers to a processing method that involves plastic deformation, which is defined as a deformation that leaves permanent changes. This plastic deformation is performed using molds and is called "forging." Forging processes are classified based on the temperature of forging into hot forging, warm forging, and cold forging. Hot forging occurs at temperatures between 1000 and 1250°C, warm forging is between 300 and 900°C, and forging performed at room temperature (or in an environment close to room temperature) is referred to as cold forging. *For more details, please refer to the external link page or feel free to contact us.*

Our company maintains a consistent process for product development from the conceptual stage of rough sketches to mass production in-house. Even if issues are discovered during the production process, we can quickly trace back through the steps to identify the cause, allowing for speedy improvements and corrections. We handle many projects starting from rough sketches and conceptual proposals, and we excel in making specifications that consider mass production in terms of cost, quality, weight, and workability from the prototyping stage. *For more details, please refer to the external link page or feel free to contact us.
