Company PR
Hiroshima-Yamadai manufactures products under received orders by plastic molding with the integrated production system covering from injection molding of variety of plastic parts in small lots to assembly. In particular, for insert and outsert moldings for which special technologies are required, we have accumulated extensive technologies and know-how over many years. For general automotive parts or other parts, necessary materials and molds are supplied from users. On the other hand, insert molding requires special product design, therefore we integrate the concept of customer’s new product into our product design and mold manufacturing in cooperation with other companies belonging to the same group in order to offer satisfactory injection-molded products. These efforts have grown us to a company which develops specific technologies. We will respond new customers’ requests on a daily basis by combining the mutual technologies in the group.

Primary Area of Technical Expertise

Our company specializes in insert and outsert moldings which require special technologies in plastic small precision injection molding. In the insert molding*1 and outsert molding*2, it is important to participate in the concept design phase of customer’s new product and integrate the concept into our product design and mold manufacturing, therefore specific precise technical know-how is required. We have accumulated the technologies over many years with much effort invested in product design and mold manufacturing technology development. *1: In the insert molding, an insert is placed into the molds, then molten resin is injected around the insert and solidified. *2: In the outsert molding, resin is affixed on a part of the outsert object by molding to integrate them.
