Punching press processing of light-shielding sheets that require strict precision and cleanliness! It is used in optical devices such as digital cameras.
We conduct punching processing of light-shielding sheets used in optical devices such as digital camera shutters and apertures, which require extremely strict precision and cleanliness. We have successfully achieved mass production with our unique burr-free processing that minimizes burrs generated during material cutting. All of our production sites are clean rooms classified as Class 10,000 to 100,000, allowing for the entire process from material input to packaging to be conducted within the clean room. We also specialize in lamination and bonding processes, combining multiple machines such as presses and laminators on a single line for processing. Since we can punch materials into different shapes and perform online lamination and bonding, we can offer low costs and short delivery times. You can rely on us for bonding using double-sided tape or punching and pressing of laminated products. We have also introduced the same equipment in our factories in China and Malaysia, enabling mass production with the same quality as in Japan.

Company information
Our company is an electronics parts manufacturer that specializes in die-cutting functional materials such as films, double-sided tapes, and cushioning materials. Among these, smartphone components have been adopted by all domestic manufacturers and some overseas, currently accounting for 70% of our total sales and becoming our flagship product. There are many die-cutting manufacturers around the world, but our significant strength lies in the fact that we design and develop most of our processing machines and molds in-house. This allows us to quickly introduce new products as needed, enabling us to respond swiftly to rapidly changing demands and smoothly accommodate specification changes for remodeling.
