"Swing Forging" is a method within the rotary forging process where only the upper die swings, shaping the material through repeated partial processing. The characteristics of this method include a small pressing force that does not apply pressure impactfully, allowing for the use of smaller equipment that traditionally required large-scale setups, while also suppressing noise and vibration generation. As a result, it leads to a reduction in manufacturing costs for machine dies and expenses for soundproofing and vibration control. Furthermore, it does not require special foundations for installation and can be easily connected to machining lines. **Features** - Small pressing force that does not apply pressure impactfully - Leads to a reduction in manufacturing costs for machine dies and expenses for soundproofing and vibration control - Does not require special foundations for installation and can be easily connected to machining lines - Low friction on the die surface against material flow, improving processing limits - It is also possible to finish products that were traditionally processed at elevated temperatures using only cold processing. *For more details, please refer to the related links or feel free to contact us.*

Although it is generally referred to as "forging," it is actually distinguished by "working temperature" and "deformation method." Hot forging involves heating the material to soften it for forging, resulting in lower deformation resistance and the ability to create complex-shaped parts. Cold forging offers higher forming accuracy than hot forging and can reduce machining processes in subsequent steps. Additionally, free forging involves setting the workpiece in a jig and shaping it with a hammer or similar tool. It requires skilled techniques and is suitable for small-scale production, while die forging uses forging molds and is suited for mass production. [Classification by Working Temperature] ■ Cold Forging: Forging without heating the material at all (at room temperature) ■ Warm Forging: Forging with the material heated to approximately 600°C to 850°C ■ Hot Forging: Forging with the material heated to approximately 1,200°C *For more details, please refer to the related links or feel free to contact us.

Metal material processing includes forging, casting, pressing, and powder metallurgy. "Forging" is a method of shaping metal materials by striking or applying pressure to achieve the desired shape. This processing method allows for the production of products with superior "toughness" characteristics, which are more resilient and less prone to impact failure compared to other methods. 【Features】 ■ Metal flow that conforms to the product shape increases strength ■ Applying pressure results in a dense structure with no internal defects ■ The final product is completed in a shape close to the desired form, simplifying subsequent machining processes ■ Weight reduction is achieved by maintaining equivalent strength while reducing wall thickness, eliminating material waste ■ Excellent mass production capability *For more details, please refer to the related links or feel free to contact us.
