● The production time for cast prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. Even if changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be modeled at the same time in one molding process. This allows for the verification of multiple types in a short period.

Features of Gravity - Smooth surface finish - High precision - Low tendency for defects It is possible to manufacture molds for small-scale production at a low cost and with a short lead time, and we are conducting prototyping (small-scale production) using these molds. Generally, aluminum castings produced in mass production molds are prototyped using sand casting methods due to the low initial costs and short lead times for small quantities. However, sand casting methods have a slow cooling rate, making it easy for defects (pinholes) to occur, which can complicate proper product evaluation during prototyping. *Please refer to the PDF for details.
