東新プラスチック Company Profile

We aim to be a good partner and a good advisor to our customers by possessing the technical skills to respond promptly to their needs.

Our company, as the plastic division of Tōshin Kōgyō Co., Ltd., was established in 1961 and became an independent sister company in 1964. Since our founding as a synthetic resin injection molding processor, we have received support from a wide range of customers, including those in the fields of low-voltage and high-voltage equipment parts, automotive parts, OA equipment parts, and communication equipment parts. We have consistently focused on improving product quality and continuously enhancing our technology. In addition, to meet customer demands for quality improvement, strict adherence to delivery schedules, and enhanced service, we established a mold manufacturing division in 1981, strengthening our facilities and capabilities to enable consistent orders from mold production. In February 2005, we obtained ISO 9001:2000 certification and will continue to pursue further organizational strength and customer satisfaction through ongoing improvements. Our thin-walled molding technology and ultra-fine hole molding technology are among our proudest capabilities. With years of accumulated know-how and a network built over our 50-year history, we have established a consistent order system from molded individual parts to finished products, enabling us to respond to diverse customer needs. We also manufacture and sell special microphones, headphones, and acoustic accessories under the TOSHINE brand as our own developed products, receiving support from both domestic and international customers.
