PP Roll Extruder
The PP roll extruder is used to produce plastic sheet or rolls. The material can be PP,PS and PE. The sheet can be used in thermoforming machine to produce disposable plastic cups, lids, trays, boxes, etc..
PP roll extruder features:
1. Such main part as machine, roller, and screw stem all use of the high quality structural alloy steel (CrMoAIA), which passed nitrogen treatment, have the high hardness, strong corrosion resistance, and the long operating life.
2. The head of the PP roll extruder is an adopted hanger-type branch pipe decreasing-style construction, so the flow passage is convenient for solution to flow without stagnation, and the thickness of products will be smooth and even.
3. The calender roll axle which jointed with the heavy steel tube and around axes with flange, the surface is by chrome plate and fine grinding with grinding machine, smooth can be up to more than 0.5, have enough hardness, rigidity and durability.
