長浜合成工業所 Company Overview

As a comprehensive pioneer in plastics, we aim to be a company that delights our customers by focusing on integrated production, including mold design and manufacturing.

Nagasaki Gosei Kogyo Co., Ltd. has been dedicated to the manufacturing of plastic products since its establishment in 1966. In terms of molds, we have a partner company in South Korea in addition to our own factory, and we are confident in our ability to handle short lead times and bulk orders for multiple molds. "Manufacturing" is very important in resource-scarce Japan, and we position it as a crucial corporate philosophy that must not be forgotten. We believe that striving for "manufacturing" with a focus on the field is a social corporate value. As the plastic products industry increasingly engages in the recycling sector, we will continue to strive to contribute to society as an "environmentally refined company" that creates a rich natural and living environment.
