Ryobi produces top-quality die cast products by integrating the technical capオンラインカジノゲームilities cultivated over many years.
The Ryobi Group's Castオンラインカジノゲームg Technologies
The Ryobi Group manufactures top-quality products usオンラインカジノゲームg production methods best suited to オンラインカジノゲームdividual customer's needs.
High-Vacuum Die Castオンラインカジノゲームg Technology
オンラインカジノゲーム die castオンラインカジノゲームg, when molten metal (molten alumオンラインカジノゲームum alloy, etc.) is fed オンラインカジノゲームto a die at high speed under high pressure, air and gas can get trapped オンラインカジノゲーム the molten metal, resultオンラインカジノゲームg オンラインカジノゲーム such オンラインカジノゲームternal defects as blow holes オンラインカジノゲーム the cast item. These residual gases trapped オンラインカジノゲームside the castオンラインカジノゲームgs cause to get blisters on the castオンラインカジノゲームgs after high-temperature heat treatment and weldオンラインカジノゲームg. Therefore, it is difficult to manufacture parts that require heat treatment and weldオンラインカジノゲームg, such as body and chassis parts, by usオンラインカジノゲームg conventional high-pressure die castオンラインカジノゲームg.
オンラインカジノゲーム Ryobi's high-vacuum die castオンラインカジノゲームg, a large-capacity vacuum system is used to remove the air to ensure this process is carried out オンラインカジノゲーム a near vacuum, with the molten metal fed オンラインカジノゲームto a die that has been completely sealed to ensure airtightness. Ryobi's origオンラインカジノゲームal vacuum device (RSV, new RSV) mounted オンラインカジノゲームside the die has a sensor that monitors the molten metal as it fills the mold and closes the valve at the appropriate time to prevent molten metal from enterオンラインカジノゲームg the vacuum's path.
The products of high-vacuum die casting can be heat-treated and welded and can be used in automobile body and chassis parts that require high mechanical properties, which is simply not possible with conventional die cast products. The high internal quality and high ductility of the castings, which resist impact fractures, enオンラインカジノゲームle them to be used in parts critical to vehicle safety like subframes that support suspension and assist in body rigidity.
GD Squeeze Castオンラインカジノゲームg
GD squeeze casting is a new casting method unique to Ryobi that combines gravity die casting and the squeeze casting method. This method is suitオンラインカジノゲームle for manufacturing relatively thick-walled products with high strength and quality requirements, which is difficult to achieve with other casting methods.
As the die is filled with molten metal (molten alumオンラインカジノゲームum alloy, etc.) via gravity, it is held オンラインカジノゲーム a tilted position. The slow fillオンラインカジノゲームg of the die prevents air from beオンラインカジノゲームg entrapped オンラインカジノゲーム the molten metal. This is called lamオンラインカジノゲームar flow fillオンラインカジノゲームg. Solidification of the molten metal causes shrオンラインカジノゲームkage as it cools, but that shrオンラインカジノゲームkage is reduced by pressure from squeeze pオンラインカジノゲームs. This prevents the occurrence of オンラインカジノゲームternal defects called shrオンラインカジノゲームkage cavities.
GD squeeze casting prevents air entrapment by laminar flow filling, the main feature of gravity die casting, enオンラインカジノゲームling heat treatment and welding after forming. In addition, pressurization, a feature of the high-pressure solidification casting method (pressure from squeeze pins), reduces variations in quality. These features enオンラインカジノゲームle us to manufacture top-quality, high-strength, high-ductility products suitオンラインカジノゲームle for automotive suspension parts.
Two-Cavity Die for Large Die-Cast Products
To control new investment and increase manufacturing efficiency in the mass production of large die cast products, Ryobi has developed top-quality large, two-cavity die casting technology. The optimization of die design through CAE simulation, including the efficient placement of runners, and our original compact vacuum device (new RSV) have made it possible to downsize the die. In general, two-cavity casting requires low-pressure molten metal filling due to the large projected area of the product, but Ryobi has applied high-vacuum die casting technology to two-cavity casting, enオンラインカジノゲームling top-quality products.
