Partial chrome plating only on necessary areas! There is no need to remove the auxiliary parts of the mold that were required for conventional plating processing.

We have a track record of deliveries to major automobile manufacturers! The partial chrome plating repair for large molds, 'TUP (Teikuro Touch-Up Plating),' is Teikuro's partial repair plating technology that achieves both no disassembly and ultra-short lead times. By applying partial chrome plating only to the necessary areas, there is no need to remove the auxiliary parts of the mold that were typically required for standard plating processes. As a result, it contributes to reduced total costs and shortened lead times. 【Features】 ■ Partial plating repairs can be done only where necessary, when needed ■ Lead time as short as 4 hours ■ No need for disassembly and reassembly of auxiliary parts before and after plating ■ Maximum processing area per location: 200mm x 200mm 【Benefits】 ■ Minimal changes in contact after plating ■ No need for assembly work of auxiliary parts ■ Reduction in the amount of panel indentation due to plating ■ History tracking of peeling areas *For more details, please download the materials or contact us.

• Testing Equipment and Devices

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Our company sells PDCE devices and the supports and fittings for installing these devices in various locations. The new lightning rod "PDCE Lightning Ball" is designed to "avoid" lightning strikes by incorporating features that make it difficult for lightning to approach, unlike traditional lightning rods. Its round shape and double structure with an insulator help suppress "welcoming discharge," which attracts lightning current. This lightning protection system complies with the lightning reception requirements of the "Building Standards Act." Rakurai Yokusei Systems Co., Ltd. https://www.rakurai-yokusei.jp/
