Rubber speed bumps are widely used in communities, institutions, factories, highways and other places where vehicles need to slow down. It is a very important road vehicle deceleration device and a common equipment in transportation facilities. In order for everyone to better understand and use it, let's introduce the calendering and extrusion process of rubber speed bumps:
　　 calendering process
　　 Calendering is a process in which the rubber compound is made into a film on a calender or is made into a semi-finished rubber cloth with a skeleton material. It includes operations such as sheeting, laminating, pressing and textile hanging glue.
　　 Rubber speed belt groove rolling process generally includes the following processes: preheating and supply of rubber compound; guiding and drying of textiles (and sometimes dipping).
　　Extrusion process
　　Extrusion process is to make the rubber material achieve the purpose of extrusion and preliminary modeling through the action of the barrel wall and screw part of the extruder, and the extrusion process also becomes an extrusion process. The main equipment of the extrusion process is an extruder.
