In recent years, with the tightening of global environmental protection policies (such as plastic restriction order and low-carbon emission reduction requirements) and the improvement of the performance requirements of downstream industries, the market demand for foamed plate continues to grow - not only does the product need to have higher mechanical strength (such as compression resistance and impact resistance) and more stable physical properties (such as low shrinkage and uniform density distribution), but also needs to meet the "green production" demand (such as using environmentally friendly foaming agent and reducing production energy consumption), which puts higher requirements on the technical performance of the core production equipment of foamed plate - the extruder.
[0003] At present, the production of foamed plate is mainly realized through extrusion molding process, which requires mixing high polymer material with foaming agent and then heating and melting, and then extruding and molding through the extruder.
