Mold is the prototype of actual final products, hence a moldユs high-dimension accuracy and durability are very important. Besides, it is important to fabricate quality molds within short time at low cost. The mold fabrication starts by machining with high-technology facilities such as NC machine, machining center and electric discharge machine. Then, at later stage, the mold is finished-up by skillful engineers. This fine adjustment by engineers is necessary in order to achieve curve-free surfaces. The mold fabrication is not finished at this point. The mold dimension accuracy will be checked, followed by molding trials and inspection on cast products to confirm whether it matches the design quality. The mold fabrication requires both high-technology facilities and skillful human-hand fine-finishing. Our high quality die cast is the result of highly reliable molds.
