Here is a case study of casting pure copper electrical components. 【Challenge】 We want to maintain electrical conductivity (IACS). 【Proposal】 We propose creating pure copper castings using the lost foam casting method. 【Solution】 We delivered pure copper castings that meet the standard CAC103 with an electrical conductivity of over 80%, which was well received, and we have received additional requests. The "lost foam casting method" can accommodate complex shape designs! The mold cost is approximately one-fifth that of die casting, keeping costs down. By casting, we shorten processing time, and the delivery time is typically 1 to 1.5 months, allowing for quick turnaround. Additionally, integration with surrounding components is possible. *For more details, please download the PDF or feel free to contact us.

How about using sand casting? The "Lost Foam Casting Method" can accommodate complex shape designs! The mold cost is lower, approximately 1/5 of die casting, since it uses aluminum molds. By casting, we can reduce processing time, and the delivery time is usually short, around 1 to 1.5 months. Additionally, integration with surrounding components is possible. 【Flow of the Lost Foam Casting Method】 ▶ Assembly of the polystyrene model ▶ Molding: Sand is poured around the polystyrene model, and the mold is created using a vibration table. ▶ Pouring: Molten metal (high-temperature molten metal) is poured from the pouring gate, causing the polystyrene to disappear and allowing the metal to flow into the created space.

At Hidaka Alloy Co., Ltd., we have developed high-quality, high-density aluminum castings using a "new casting method." In conventional casting, it was difficult to reduce the porosity to a level suitable for vacuum equipment. However, by discovering various new techniques such as material management and melting methods, we have made it possible to produce high-density aluminum products using our unique casting method. If you have the dilemma of wanting to "actually make it by casting!" but are limited to machining due to "sealing issues," please consult with us first! ■ Please share your concerns with us! - I want to reduce machining labor hours. - There are some parts that are difficult to process internally with machining. - I want to reduce the amount of cut-off material and lower material costs. - I want to rethink the machining process itself. We will solve the challenges of "machining" with "casting"! *Please contact us for more details as this is a new and unique technology!

In general, robotic arms used in vacuum environments and semiconductor manufacturing equipment that require airtightness can develop cavities due to the presence of oxide and hydrogen bubbles during casting. Furthermore, the larger the casting, the more bubbles tend to gather within the material, resulting in larger cavities and reduced precision. With our technology, we can maintain a highly precise state at the point of pouring molten aluminum. While a vacuum is ideal, we can achieve a state close to it. Additionally, we can measure the bubble concentration within the molten aluminum using measuring instruments. In sand casting, impurities typically range from 0.5% to 1.5%, but we can reduce this to 0.006% to 0.008%. 【Features】 ■ Reduced processing time through casting ■ Ability to manufacture without being constrained by shape ■ Use of only carefully selected ingots without compromising on raw materials *For more details, please refer to the external link page or feel free to contact us.
