テイクロ List of Products and Services

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.
