Molding machine and sand mold 【Technology and Product】
Die casting
In the past, the blowhole was a major disadvantage of die-casting. However, localized squeeze casting solved this blowhole issue and blowholes are not produced even when pouring molten metal at high-speeds. Heat treatable pressure-proofed and high strength components and components with even thinner walls can also be manufactured using this casting method. Currently, we have 10 die casting machines in total and are able to cast products in a variety of sizes using these casting machines. At the same time, we promote “Single changeover” which means to change molds within 10 minutes so that we are able to manufacture products in small lots with a short lead-time quickly upon customers’ requests.
Die cast machine and handling robotSand casting and mold casting
The sand casting line is equipped with an auto-molding machine in addition to mold-setting machines; therefore, we are capable of manufacturing from a single part to parts of relatively large lot size. We also have a cold box molding line and a self-hardening molding line so that the most suitable casting process can be chosen in accordance with the purposes of the products. The mold casting line is equipped with rotary casting machines and rotary cutting machines which are both developed and produced by us in order to save manpower in the production area. With these machines as the core of the line, we developed a consistent casting process by combining them with other automatic machines so as to reduce manufacturing cost and delivery lead-time.
