First, the increasingly developing acrylic manufacturing industry has formed well-known acrylic brands such as PLEXIGLASS and ACRYLITE. Second, dedicated配套products for sign letters have also emerged, such as Acryli vacuum forming machines, letter edges, aluminum-plastic strips, and special adhesives, forming brands like VOLTARC, JEWELITE, and Acryli. Light source products such as neon lights and LEDs continue to develop targeted product series to meet their needs. Companies like 3M and ARLON have also developed new series in light-transmitting membrane products. In the vacuum forming machine aspect, professional equipment manufacturers represented by Nanjing Biya are committed to the professional production and research of acrylic sign forming equipment, giving acrylic advertising signs richer expression. Today, walking in the commercial areas of the United States, the once dazzling neon light projects are rarely seen again, while gentle acrylic signs are ubiquitous, adding infinite charm to the city.
