Foam sheet extrusion line with tandem technology & high productiviy processing.
Sunwell Global is a market leader in the supply of foam sheet extrusion lines for food and protective packaging applications. Our tandem extrusion lines are able to process EPS, EPE,XPET and EPP at outputs from 150kg/h to 1000kg/h.
Raw materials are automatically loaded and blended before being fed into the primary extruder to produce a homogeneous melt. Hydrocarbon or CO2 gases are precisely metered using triple head ATEX compliant, diaphragm pumps with mass flow measurement to ensure a consistent foam density and quality.
The secondary extruder cools the melt using a high mixing, low shear screw with a two stage seal design to ensure no leakage through the rear. Barrel water cooling is controlled through motorized valves to minimize temperature variation particularly important when producing absorbent foam.
Our oil temperature controlled annular dies have hand wheel adjustment and digital display of die gap to assist with process control and product repeatability. Air rings around die and cooling can improve surface finish and output.
Sunwell has a range of haul off and winding technology with manual or fully automatic cut and reel change capability all with accurate programmable tension control.
All foam sheet extrusion lines have the option of discrete or PLC touch screen control.
