This project is located in the United States. The client owns a coating company that specializes in the production of mechanical parts. The company provides high-quality equipment for subway systems. For a long time, it has relied on traditional manual coating operations.

Subway car bodies are large and structurally complex. Manual spraying is time-consuming, which not only leads to inconsistent coating quality but also makes it difficult to meet the demands of mass production.
To address this challenge, the client sought more efficient solutions online. After multiple rounds of communication and evaluation, QX Spray Booth stood out due to its extensive experience in spray booth projects and its mature customized solutions. Based on the client’s specific requirements, a tailored automated spray painting robot solution was developed.
