Foam Sheet Extrusion Line
- Description
Description
We are market leaders in the supply of foam extrusion lines for food and protective packaging applications. Our extrusion lines are able to process EPS, EPE, and EPP at outputs from 150kg/h to 1000kg/h.
To produce a homogeneous melt raw materials are automatically loaded and blended before being fed into the primary extruder. CO2 or Hydrocarbon 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 cooling and die can improve surface finish and output.
We have 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 lines have the option of discrete or PLC touch screen control.
