Super Punching

Super Punching

Punching press can handle small hole diameters smaller than the plate thickness!

In the processing of punching metal, what is typically recognized as unprocessable—hole diameters smaller than the plate thickness and smaller ribs—has been achieved through years of technological improvements as "super punching." It can accommodate a wide range of plate thicknesses from thin to thick, and because the gaps (ribs) between holes can be processed with a very narrow pitch relative to the plate thickness, it is possible to secure a high opening rate, allowing for use in various fields. It is also more cost-effective compared to cutting processes and electron beam processing. For more details, please download the catalog or contact us.

Contract processing services

Contract processing services

Introducing processes such as cutting, polishing, and laminating! Information about our contract processing services.

We offer contract processing for the polishing of brittle material end faces and end face coating. At Showdatectron, we utilize our technology for machinery and equipment for brittle material processing to accept orders for end face polishing of rectangular, circular, and other shaped glass materials, as well as for the coating of resin on free-form end faces. Additionally, regarding end face grinding, we can provide consistent processing from slicing the supplied ingots to centering and end face polishing through our partner factories. If you are considering processing prototypes or small lots, please feel free to consult with us. ■ End Face Polishing By polishing the end faces of CNC machined surfaces, laser-cut surfaces, and glass after scriber cutting with brush polishing, we achieve a mirror finish. This results in improved glass strength, enhanced transparency of the end faces, and visually appealing finishes. ■ End Face Coating (UV-curable resin, thermosetting resin coating) We apply UV-curable resin or thermosetting resin to the end faces of various glass materials, camera filters, metal plates, etc., and cure them to ensure protection of the end faces, improvement of substrate strength, and performance tailored to customer requirements such as light shielding. *For more details, please refer to the PDF document or feel free to contact us.

Graphite

Graphite

We can propose suitable double-sided tape/carrier film from our numerous processing achievements!

"Graphite" has high thermal conductivity in the plane direction (about 7 times that of copper and about 7 times that of aluminum) and is lightweight. It also has flexibility, but the material itself is very brittle, making it very difficult to handle due to issues such as powdering and interlayer delamination. Our company offers solutions for powdering and interlayer delamination, including pouch processing (covering graphite sheets with larger PET films on the top, bottom, left, and right) and recommendations for suitable double-sided tape/carrier films based on our extensive processing experience. [Main Processing Achievements] ■ Information and Communication: Antennas, grounding, LCD conduction, noise countermeasures ■ Automotive: Sensor substrates *For more details, please refer to the PDF materials or feel free to contact us.

Perforated separator

Perforated separator

Developed a compact and easy-to-use delivery form that can be stored like toilet paper!

To create battery cells, a sheet called a separator is necessary to insulate the cells from each other. Our company has developed a delivery form that is compact and easy to use, similar to toilet paper. When using materials like PET for protective sheets and cutting them at arbitrary locations, there are often cases where the cut does not go as planned due to material stretching. By providing perforations, it becomes easier to make cuts as desired. 【Main Processing Achievements】 ■ Information and Communication: Smartphone batteries ■ Automotive: EV batteries ■ Energy: Insulation sheets for fuel cells and all-solid-state batteries *For more details, please refer to the PDF document or feel free to contact us.

PI reinforcement plate

PI reinforcement plate

To increase strength, attach reinforcement plates for stabilization! Punch processing will be carried out at Otis.

Depending on the application, materials face various challenges such as corrosion, breakage, bending, and warping. For example, in flexible circuit boards, there are characteristics such as "thin" and "flexibility." However, due to their softness, they can become difficult to handle during component mounting. To enhance strength, reinforcing plates are attached to stabilize them, preventing warping and bending. Depending on the application, various materials such as polycarbonate, glass epoxy (FR-4), polyimide, and metal plates are used as reinforcing plates, and we perform punching processing at Otis. 【Main Processing Achievements】 ■ Information and Communication: FPC mobile devices, digital equipment ■ AV and Home Appliances: VR/AR, MR, digital camera lenses/sensors *For more details, please refer to the PDF document or feel free to contact us.

Taping

Taping

We have unique know-how that allows us to continuously perform precise punching and laminating processes!

"Taping" refers to a processing method that involves accurately die-cutting and laminating adhesive materials in a roll-to-roll manner, delivering the carrier sheet wound in a roll. Double-sided tape, sheet materials, resin films, etc., have varying handling characteristics depending on the material, and there may be cases where handling is difficult, such as "very flexible and easily stretchable," "fragile and prone to breaking," or "extremely thin and prone to wrinkling." At Otis, we possess unique know-how that allows for continuous precise die-cutting and laminating processes, achieving automation even with materials that are difficult to handle. [Benefits] ■ Shortened lead times due to improved workability ■ Stabilization of quality ■ Cost reduction, etc. *For more details, please refer to the PDF materials or feel free to contact us.
