Integration of a composite line for precision automotive parts using metal pressing and plastic molding.
We can provide one-stop solutions for designing, prototyping, manufacturing, and assembling both "metal press molds" and "plastic molding molds" with different characteristics within the same factory!
We can manage all processes up to the finished product in a centralized manner, thereby streamlining management efforts while achieving product downsizing and cost reduction. We have obtained IATF16949 (ISO/TS16949) certification for quality management in the automotive industry. We will respond from a factory with a proven track record of producing 1 million in-vehicle transmission modules per month. 【Support for Various Fields Beyond Automotive Parts】 〇 Electronic Components We provide consistent contract manufacturing from mold production to assembly and inspection of precision electronic components (connectors, switches, speakers) used in smartphones, digital cameras, etc. 〇 Home Appliance Parts We contract manufacture temperature sensors and gas sensors used in air conditioners, air purifiers, refrigerators, and more. 〇 Disaster Prevention Parts We custom design and produce speakers, which are critical components used in gas alarms, fire alarms, medical devices, and industrial equipment, according to the requests and needs of major manufacturers. To ensure "safety and security," we conduct assembly and inspection in a clean room (class 100,000).
