Mold technology

Casting analysis

In the process of fabricating die-castings, a variety of different kinds of defects can occur, such as air entrapment,molten metal runoff,shrinkage cavities and shrinkage cavities. The performance of casting analysis enables results to be ascertained in advance and optimal mold design work to be carried out thanks to the visualization of the process by which molten metal is poured into the mold and allowed to solidify. The resulting reduction in the number of prototypes helps shorten delivery times and improve quality and facilitates further improvements in the quality of existing products and the production of larger, complex products.


Initiatives for the in-house production of molds

In 2021, we established the Kumagaya Mold Center and commenced in-house production in order to shorten delivery times and develop technologies. We possess the capacity to fabricate molds for use in the 3,500-ton class of die-casting machines and primarily make medium- and large-sized die-casting molds. When we fabricate molds in-house, we can participate in the entire process from the form-examination stage prior to the acceptance of orders. This lets us quickly identify and address problems as they arise. Furthermore, we have dramatically reduced delivery times by integrating all of the steps in the designing and fabrication of molds. We are also setting up mold-fabrication technologies in-house in order to consolidate know-how in terms of our proprietary mold designs and commit ourselves to further studying mold technology.
