Production in 4 countries worldwide
The main products of the DENKI (Electric) Device Company are "wire harnesses" and "power cords". We use our accumulated knowledge to respond to market needs, manufacture not only in Japan but also at overseas base factories, and sell to local manufacturers in China and Southeast Asian countries as customers.
At our factories in Anhui and Jiangxi provinces in China, we carry out integrated production from electric wire production to harness and power cord assembly, to meet the needs of our customers. We are working on new products in new fields with new customers by making use of the know-how of "parts management," "quality control at the PPM level," and "process control," learned in wire harness production, and the know-how of "100% quality assurance," "molding technology," and "system for safety and security," learned in power cord production.
Wire harness
When production started in 1960, soldering was the mainstream method for connecting terminals to electric wires, but we were the first to introduce the new "solderless terminal," component and thereafter expanded production. We have now grown to carry out production at each base factory in Japan, China, Thailand, and Cambodia, and our products are used in a wide range of fields, including consumer electronics, home appliances, industrial equipment, and automotive parts.
Power cord
When production started in the 1950s, most power cord plugs were prefabricated. However, we were the first in the industry to introduce "polyvinyl chloride (PVC)" material and produce "integrally molded plugs," which are produced by pouring materials into a mold.
Since 1965, we have acquired safety standards and manufacture and sell all over the world.
In addition, the DENKI (Electric) Device Company works with customers to develop and manufacture heater wires that prevent the wheels of bullet trains from freezing, various safety parts used in nursing beds, and waterproof plugs.
