PS Sheet Extrusion Machine
The PS sheet extrusion machine 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..
In the form of sheeting, the upper surface of the three-roller intermediate roll should be on a horizontal plane with the lower surface of the mold lip. The lip end face is parallel to the center line of the intermediate roll and is 50-100 mm apart.
The lip gap of the mold should be slightly less than or equal to the thickness of the sheet. The intermediate gap of the lip should be slightly smaller than the lip gap on both sides.
Note that the roughness R of the three-roll working face should be no more than 0.2 pm. Do not use a hard knife to scratch the roll surface when cleaning the roll surface. Use a copper knife to clean the roll surface residue.
