There are as many as 200 manual processes involved in making an optical frame. Generally, productivity is low when one company is in charge of all the processes. However, Masunaga Optical is the only company in Japan that has a factory in charge of all processes from raw materials to production and finish in an integrated way. The integrated production system improves the detail and quality. For example, when Masunaga Optical develops a new model, the molds are always built in-house. If there is a problem in the wear comfort that can be felt only after completing one pair of glasses, it will be corrected in the previous process’ promptly.
