It has gradually developed and improved with the development of hot melt coatings, and is a highly automated machinery. Construction requires a set of several equipment to complete the construction functions of each link from melting to marking. This set of equipment generally consists of a hot melt kettle, a marking machine (including a zebra crossing marking machine), a pre marking machine, and a bottom coating machine. Of course, users can choose different models, grades, and functions of equipment configurations based on their own economic strength, project size, and level of specialization. The hot melt marking machine in the configuration can be divided into three types based on its marking method: hot melt scraping type, hot melt extrusion type, and hot melt spraying type.
