井山工作所 Company Profile

Manufacturing that provides the highest trust and maximum peace of mind.

We specialize in horizontal machining of thin and complex castings (FC, FCD, AC) across various fields. Since we design and manufacture the processing jigs in-house, we can quickly and accurately process complex shapes and thin materials, which are difficult to set up, from prototypes to medium lot sizes with minimal steps. After processing, we ensure precision with an inspection system equipped with a CNC three-dimensional measuring machine. With a reliable management system at our ISO9001 and ISO14001 certified factory, we are fully committed to meeting the QCD requirements of our customers.
