Plastic Precision Molds
Molds guaranteed from the mold up to the final product stage.
RICOH Industrial Solutions Inc.'s manufactures a wide range of products in different fields, such equipments are office electronics use, projectors, medicine, communication. From mold design of optical elements to actual production.In recent years, we have also engaged in manufacturing molds for plastic lens and lenses with a greater bend surface range. The technical knowledge we have amassed up to now is not applied only to the manufacture of metal molds, but also employed to satisfy our customers in all sorts of ways based on our motto of "MOLDS GUARANTEED FROM THE MOLD UP TO THE FINAL PRODUCT STAGE." We are also available for consultations regarding taking customer mold orders or engaging in joint development work, etc.
