Kafeal Corpration

We manufacture cores for mirror surface molds within a shape precision of ±1 µm.

We manufacture optical plastic lenses and precision engineering plastic components. Optical plastic lenses are increasingly becoming more complex and high-precision. Our company has successfully developed products at the submicron level, and manufactured sophisticated products such as mirror finish mold cores. This is done by making the most of our transfer technology. We measure shape precision with an ultra-high-precision 3D shape measuring instrument and a laser interferometer.

[Company strength]
We supply optical plastic lenses at low cost with a stable production method.
Our lenses are manufactured 24/7 in an unmanned cleanroom with automatic temperature and humidity control, using an automation system consisting of an automatic stocker and other equipment.
We possess optical plastic lens manufacturing technology.
Manufacturing technology for optical plastic lenses, which are needed in the advanced optical industry field, is our company’s strength. We can start operations from the optical design and mold making phases. 

[Business description]
Our company pursues the infinite possibilities of plastic, and we specialize in optical plastic lenses and precision engineering plastic components. We contribute to society by providing superior products that please our customers. Arranging a proper environment is one of our basic principles. This is why our high-precision, high-quality plastic lenses are manufactured 24/7 in an unmanned cleanroom with automatic temperature and moisture control. The entire company is committed to TPM activities in which molds and molding conditions are thoroughly managed by qualified molding workers in an effort to stabilize quality. 

Plastic molding

[Strength of products/technologies]
Our optical plastic lenses, prisms, and mirrors are manufactured with submicron-level shape precision in a stable manner. This is done in a cleanroom where the production environment is stabilized by an unmanned automation system. We manufacture mirror surface mold cores with shape precision within ±1 µm. Our lens moldings copy the shape as faithfully as possible. We also measure shape precision with an ultra-high-precision 3D shape measuring instrument and a laser interferometer. 

[Representative's message]
Optical plastic lenses are becoming increasingly complex and high-precision. We will continue to satisfy our customers’ needs through mass production of injection molding utilizing high-precision transfer technology. We will do this so that we can continue to supply the market with safe and secure optical plastic lenses while adding more advanced features. I cherish the Japanese Monozukuri craftsmanship tradition, and seek to maintain a typically Japanese attitude of earnest sincerity. We aim to become a company that is technology oriented, and yet compassionate: a company that our customers feel good about relying on. 

[Company structure for market development/overseas expansion]
Our management group functions as the point of contact for inquiries and transactions, but projects are actually led by the president, who is familiar with our technologies. Our Kyoto office is conveniently located on the premises of the Kyoto Research Park, which we hope can be advantageous to our customers.
