Although the reasons for the three-dimensional sheet metal plate due to the low molecular weight fluid tight. The molecular weight of the polymer is high, high viscosity, the flexibility of the molecular chain, the greater the normal stress difference, climbing pole phenomenon is more obvious, plastic mixing rolling encounter similar viscoelastic phenomena forming. The material has a unique plastic molding properties, such as good three-dimensional plate materials extrusion, molding three-dimensional wall panel manufacturers, sentence plasticity plastic. It is a variety of plastics molding methods such plasticity of every kind of products, and access to a wide linear polymer long chain molecular structure, long-chain molecules runs through the other side, this overlap intertwined to form a so-called random coil structure. The entire production line from the extruder die, the die body and auxiliary components. Mainly by the die mold body, stereotypes die, tank composition. Added the mold material extruder barrel heating by melting and plasticizing screw stirring backward population molding three-dimensional pinch, die by the transition board, compression board raw material in the molten state triage compressed 3D pinch, to produce molding pressure necessary to finally obtain a homogeneous material stream and the same shape and cross-sectional shape of the product through a die 2, the die 1, the shape of the material through the machine's traction pull bow I into a sizing die, the material in the sizing die in After a three-dimensional vacuum pinch offer, such as the role of cooling water holes making the material more accurate cross-sectional dimensions. The last still pull bow 丨 machine cabinet role into the tank through the materials in direct contact with the cold water and the water in the negative pressure profiles final cooling stereotypes, get qualified products.
