Used in footballs, this technology enhances flight stability, shape retention, and accuracy.

Advanced Surface Materials

Molten develops proprietary synthetic leather and rubber compounds designed to provide better grip, improved durability, consistent bounce, and stable air retention.1

Molten has partnered with numerous international sports organisations, including FIBA, the International Handball Federation (IHF), the Japan Football Association (JFA), and various national basketball, volleyball, and football federations. Its basketballs have been used in multiple FIBA World Cups and many top-level international tournaments.13

Molten operates manufacturing and sales facilities in several countries, including Japan, the United States, China, Thailand, Vietnam, Mexico, and Germany. Its products are sold in over 100 countries through distributors, sports retailers, schools, and professional organisations.1

Molten believes that sport creates emotional connections and strengthens communities beyond mere competition. The company’s current sports mission is to “create the most optimal product and the most optimal environment that bring out the real emotion felt from participating in sports.” Its overarching sports vision states: “The emotion is the reward of sports.”2

Molten is widely recognised for premium-quality sports balls, precision manufacturing, innovation in ball design, long-standing partnerships with international sports federations, and reliability in professional competition. Its basketballs are particularly well regarded for their grip, balance, durability, and consistency, making the brand a standard choice for many international competitions.3
