About Plastal

Founded in December 2017 by CEO Hong Seong-ho, a former department head at LG Electronics' smartphone metal division, Plastal is a chemical research institute specializing in original technology for bonding metals and polymers. The company provides integrated solutions that encompass core bonding technology, mold technology, injection conditions, and CNC machining. This enables them to offer a total mechanical and chemical engineering service to their clients. Plastal's core offering is a waterproof bonding solution for dissimilar materials, developed to replace traditional methods that are often complex and costly. The technology allows for the direct and strong bonding of various metals (such as aluminum, stainless steel, and titanium) with different types of plastic resins through an injection molding process. This process aims to reduce manufacturing costs, shorten lead times, and facilitate the production of lightweight, waterproof, and dustproof components. The company's solutions are applicable across several industries, including mobile phones, electric vehicles, and other electronics. For example, in mobile devices, their technology is used for parts like antennas, SIM trays, and chassis to improve durability and reduce weight. The company has achieved significant milestones, including being selected as one of the top 100 materials, parts, and equipment startups in 2020 and winning the grand prize in the 2021 'Challenge! K-Startup' competition. Plastal has also been successful in attracting investment, securing a notable funding round in late 2025. In 2023, the company announced plans to establish a new manufacturing facility in Asan-si to expand its production capabilities.
