Kyoei Sangyou Co., Ltd.

We have a track record in proposing high-value-added plastic products.

We are a manufacturer of plastic products that was founded in 1972. We have an integrated system covering from industrial resin product mechanism development to metallic mold design, product manufacturing, and assembly. We make proposals to manufacture plastic products with high added value. We propose products with compound functions, in which new functions are added to conventional products. We are building up a track record of applications in fields such as automobiles, two-wheeled vehicles, game machines, insect proofing, and medical treatment. Our plastic cases that enclose our original RFID tags have been adopted as information management containers that resolve problems with barcode management.


Other presentation

[Company strength]
Our goal is to add compound functions to plastic products. We have advantages in technology proposals for the overall creation of added value. We can provide support from models to finished goods. We realize products with functionality, products with wisdom, and products that achieve low costs. We also have advantages in physical property inspection using product inspection equipment (environment, durability, balancer), and metallic mold maintenance using ultrasonic cleaning equipment. We are particularly highly evaluated in metallic mold design and manufacturing for our mechanism development and planning and proposals for good products, mass production, durability, and so on.
