Contract-manufactured products

From a die design to molding, painting and secondary processing,
from large to small precision molded products,We cover all your needs.

Taking the full advantage of the inherent qualities of plastic material, we have established an integrated production system based on injection molding technology. We cover everything from cast design and fabrication to molding and secondary processing (assembly, painting, printing, etc.).

We also offer proposals for converting different materials, such as metal, into resin and provide integrated production covering the design and development stages through to mass and OEM productions.

We have bases in Japan and overseas (China, Vietnam, Thailand, and Indonesia), where we produce industrial plastic molding products that are environment-friendly and meet the widespread demand for plastic molding processing, both domestically and internationally. Utilizing a wide range of processing technologies under a comprehensive quality control system, we provide high-quality products and services in various fields through timely recognition of changing market environments and diverse needs.
