“Developing highly advanced techniques through on-site innovations and industry-academic-government partnerships”

GR Engineering and Manufacturing began with producing spokes for bicycles and motorcycles and expanded their product range with long bolts, hollow rivets, and precision shafts. This, along with more diversified and sophisticated customer needs, led Tsukiboshi to concentrate their efforts on developing new techniques which they have now fine-tuned to perfection. With efforts in industry-academic-government partnerships along with continued innovations on the factory floor in in-house manufacturing of machinery and equipment etc, we continually strive to make further advances in our core technique of cold forming.

Cold eading & Forging

Cold heading, also known as cold forming, is a process where metal parts are shaped without heating the material. It involves pressing a metal blank into a die under high pressure to achieve the desired form, often requiring multiple steps for complex shapes. Forging enables the formation of intricate shapes and enhances mechanical properties such as toughness and fatigue resistance, making it suitable for applications requiring high strength and durability.

The Pressing Process

Pressing is a versatile technique used to shape materials into a wide variety of forms. At GR Engineering, by employing pressing as a secondary process following our core technique of cold forming, we have achieved the production of products that were previously very challenging. Furthermore, by developing manufacturing methods that capitalize on the features of pressing, we aim to manufacture more complex and precise products.

Secondary Processing

Secondary processing plays a pivotal role in enhancing the functionality, durability, and aesthetic appeal of components. Beyond initial fabrication, secondary processing encompasses a range of crucial techniques and operations. Heat treatment modifies metal properties like hardness and toughness, vital for components such as engine parts and gears.
