GMJ Company Profile

GMJ provides tire molds that exceed expectations and brings victory to our customers.

There is a saying, "Iron is the treasure of civilian life." Among the five metals (gold, silver, copper, lead, and iron), iron is the most widely found and the most useful metal on Earth, having been closely associated with humans since ancient times. Since our founding in 1953, we at GMJ have focused on iron, valuing our relationship with it, and have always made sincere product creation our motto, walking alongside iron. Through this unwavering effort, we have built a wealth of technology and experience, and a solid track record. As specialists in mold manufacturing across a wide range of fields, particularly in vehicle and aircraft tires, as well as industrial gaskets, we have established a strong position over many years. Rather than solely pursuing corporate performance, we aim to create products and a company with high added value as our management goals, and we wish to effectively utilize our excellent skills to greatly contribute to the development of people's lives. We kindly ask for your continued guidance and encouragement in the future.
