Products with undercut shapes can be easily demolded! Casting is possible even for products with fine gaps in their shapes!
In "die casting," product shapes with undercuts may be rejected for casting because they cannot be removed from the mold during demolding. Additionally, in "ceramic shell casting," product shapes with gaps of less than 1 cm cannot be cast because sufficient layering cannot be achieved, resulting in brittle mold strength. Therefore, with the "block mold method," the gypsum molds can be easily broken apart by striking them, allowing for the casting of product shapes with undercuts. By pouring a slurry (liquid) made of water and gypsum into the mold, it is possible to cast even intricate product shapes with fine gaps. *For more details, please refer to the PDF materials or feel free to contact us.*

Company information
Our company, established in 1960, was the first in Japan to develop and sell domestically produced casting machines for jewelry, making us the longest-established casting machine manufacturer in the country. Currently, we manufacture and sell both analog and digital devices for melting and casting various metals and alloys, not only for the jewelry industry but also for companies in all sectors. We do not just sell products; we provide technology. We propose the most suitable casting machines while listening to what our customers want to create, and we also offer customization based on their requests and suggestions for consumable materials that match their products. After purchase, we support our customers to ensure they can create products that align with their vision under our technical guidance. Additionally, we are focusing on proposals for casting production using 3D printers and low-cost prototyping technologies, contributing to the future of "Japanese manufacturing."
