PP PS Sheet Extrusion Machines
PP / PS Sheet Extrusion Machines – High-efficiency and precision sheet extrusion equipment
BC Machinery 's PP/PS sheet extrusion machines are specifically designed for the continuous and efficient production of polypropylene (PP) and polystyrene (PS) sheets. These machines are widely used in food packaging, stationery sheets, thermoforming, advertising boards, medical packaging, and other fields.
Product Advantages
High extrusion stability
The high-torque gearbox and optimized screw design ensure uniform melt and no degradation even after long-term operation.
Precision roll forming
The three-roll calendering unit has independent temperature control and servo adjustment, and the thickness accuracy can reach ±0.02mm, with a smooth surface without crystal points.


Energy-saving and efficient
Full frequency conversion drive and intelligent heating system save 15%-20% energy compared to traditional models.
Intelligent control system
Standard configuration includes PLC and human-machine interface, supporting recipe storage, remote operation and maintenance, and fault self-diagnosis.
Integrated line control
Seamlessly integrates with Bangcheng's automatic batching system, vacuum feeder, and crystallization drying system to achieve an integrated extrusion solution from raw materials to finished products.
