Understand the technology of laminating machine in one article: From principle to black technology, how to change production?
Have you ever wondered how the packaging bags for putty powder building materials and waterproof woven bags for cement are produced? The answer lies in a technology called "laminating"! Today, let's reveal the hero behind the scenes - laminating machine , and see how it uses high temperature and pressure to turn ordinary materials into powerful composite materials. 1. The magic of laminating machine: from plastic particles to composite film The core work of the laminating machine is like "dressing" the material. Taking the extrusion laminating machine as an example, its work process is divided into four steps: Feeding: Plastic particles are added to the hopper and fed into the extruder through the conveying device. Heating and melting: The particles are heated, sheared and plasticized in the extruder to form a uniform molten plastic melt. Extrusion coating: The molten plastic melt is evenly extruded through the extruder head (die lip) and coat...
