Moulds

Tohshin Seiko designs and manufactures moldiing tools for precisioninjection molding and precision metal stamping pressing.Our injection molds are best suited for producing lens-barreland lens-frame parts for digital cameras and digital video cameras, functionalparts for office appliances and automotive parts, and also plastic lensand other optical parts.Stamping press dies are available for parts used in variousfields in addition to digital cameras. Design and prototype making forwide-range applications are also offered.Our operation consists of product design, tooling design, toolmaking, commercial production and evaluation of the final product. Withsophisticated performance of our skilled engineers gained from our integratedproduction line, we can provide you with the micron-ordered injection moldsand stamping press dies you need. Not only the tooling itself, we alsohave enough experience to satisfy you with our ideas at your product designingphase.Lens barrel with cam-mechanisms inside and out.(image)Mold/Die Making Technology and Accuracy1.
