Auto Parts Manufacture
Miyamoto promotes 5S (Seiri (sorting), Seiton (organizing), Seiso (cleaning), Seiketsu (sanitizing), Shitsuke (sustaining)) and improvement activities to strive for production efficiency and quality improvement.
Improving work environment and standardizing work processes prevent errors and defects from occurring.
Each of our employees implements 5S and improvement activities, which leads to high productivity and quality of work and cost reduction.
Integrated Production
Miyamoto's in-house development capabilities ensure the production of highly-reliable products and fast response to various customer needs.
We manage internally the entire manufacturing process from design & development through parts procurement, production, shipping and quality assurance.
Our capabilities include not only production but product development, designing of production lines and manufacturing of production facilities, which enables us to provide great flexibility for delivery date, cost and troubleshooting.
We are also fully equipped with experimental facilities in order to respond precisely and immediately to testing and quality verification requirements.
Product Design & Development
Structural design, circuit design, development, prototyping and experiments ― all performed in-house to respond flexibly to customer needs
Miyamoto has established an operation process to strictly observe specifications, functions and schedules set by customers based on close collaboration among relevant departments.
Design evaluation to ensure reliability
Automotive parts are required to be highly durable for use in harsh environments and to conform with regulations of where the vehicle equipped with such parts is destined.
We have established an evaluation system utilizing endurance test facilities, measuring instruments and an anechoic chamber which can meet the latest regulations and operational environments of each country.
Production Engineering
Miyamoto's production facilities developed in-house provide competitive proposals
By developing facilities suitable for us through designing, processing, assembling and controlling facilities with good use of past problems, process FMEA, CAD/CAM and others, we can meet customer expectations for cost and quality.
We also internally design, produce and maintain plastic molding molds and develop inspection machines to prevent the outflow of defective products, so that we can immediately respond to issues at the work site.
