A two-layer PS picture frame profile can combine a lightweight foamed PS core with a denser solid PS surface layer.
The foamed core reduces profile weight and material use, while the outer layer provides a smoother, more durable surface for decorative finishing. Depending on the product design, the EANS PS profile extrusion line can be configured with a main extruder and co-extruder to produce the required profile structure.
A typical production system uses a main extruder to form the foamed PS core and a co-extruder to apply the solid PS surface layer. The two materials are combined through a customized co-extrusion die and then calibrated and cooled to maintain the required profile dimensions and surface quality.
This two-layer construction allows manufacturers to produce lightweight PS picture frame profiles with different shapes, dimensions, colors, and surface finishes according to specific market and design requirements.
