Menu of Services

1. Integrated automotie parts production

Simultaneous meeting Automatic press line

We have established a fully integrate parts manufacturing system, from pressing to welding, assembly, machining, and cation coating. In addition to providing a versatile technological service through our concurrent engineering system, we have adopted a just-in-time (JIT) system for production and distribution to reduce delivery times and costs.

2. Prototype and mass production proposals for press parts

Assembly line Cation electrodeposition coating line

Blueprint-less prototypes and mass production. We offer services to determine specifications required for mass production and concrete proposals for cost reduction measures.

3. Module order handling

3D/CAD

We have constructed a system for performing testing and measuring for module orders from automakers, including establishing a temperature controlled room housing CNC 3D measuring, contour measuring, circularity measuring, and 3D image measuring equipment.

Features of Our Automotive Parts Business

  • Feature 1

    Advanced technology drastically shortens delivery times

    We have developed a parts production process with 3D/CAD data as a central component, enabling blueprint-less prototype and mass production. Further, ingenuity at various points in the process, such as mold NC processing with CAD/CAM linkage, and automation of many production lines, has drastically reduced delivery times.

  • Feature 2

    A management system meeting global quality standards

    Four of our plants in Japan have obtained ISO 9001 certification for quality management systems, two of which have also obtained ISO/TS 16949 certification. Our facility in North America has also received ISO/TS 16949 certification.

  • Feature 3

    Reliable environmental management

    Three of our plants in Japan have received ISO 14001 certification for environmental management system quality standards as part of our active efforts to live up to our fundamental principle of "continuous development of a recycling-oriented society".

  • Feature 4

    Established a global production and distribution base

    Following to our first overseas operation in US in 1988, we have opened Mexico Plant in 2015. Furthermore, we have acquired our own production base in Thailand in 2016, establishing a global production and distribution base.
    We coordinate each other among Japan, US, Mexico, and Thailand, responding to the clients'needs for local production for local consumption.
