First, heat the extruder to the predetermined temperature, then start the screw and feed materials simultaneously. Extrusion molding is a continuous process, with the key being the adjustment of initial extrusion parameters. It is necessary to adjust process parameters such as the temperature of each heating zone in the extruder barrel, the temperature of the die head, and the screw rotation speed according to the extrusion process properties of the plastic and the structural characteristics of the extruder die head, so as to control the temperature and pressure distribution of the material within the barrel. According to the requirements for the shape and dimensions of the product, adjust the die size, concentricity, traction equipment, and other devices to control the exit swelling and shape stability of the extrudate, thereby ultimately controlling the output and quality of the extrudate until the extrusion reaches normal operation for continuous production.

Technical Definition and Core PrinciplesSolventless lamination is a production process that bonds two or more base materials (such as plastic films, aluminum foil, and paper) using 100% solid adhesives. Its core breakthrough lies in completely eliminating organic solvents. Materials like polyurethan

Industry Background and Technical PositioningAs a key equipment in modern manufacturing, coating machines have become core production tools in fields such as printing and packaging, new energy electronics, medical materials, and construction. They achieve this by precisely applying coatings, adhesiv

Industry Background and Core ValueComposite films are functional materials made from flexible materials such as plastics, aluminum foil, and paper through multi-layer co-extrusion, coating, or lamination processes. They combine high barrier properties, tear resistance, and light weight, making them

In modern industry and daily life, there is a material that seems unremarkable yet plays a pivotal role — barrier film. Like a silent invisible guardian, it relies on its special properties to protect the quality and shelf life of numerous products. As the name suggests, a barrier film is a type of
