The operation steps of a horizontal multi-layer co-extruder generally are the following main steps:
1
Preparation: Check if the equipment works regularly and prepare all needed raw materials and ancillary equipment.
2
Power-on order: Turning on the device by following the required sequence described by the operation manual to bring all parts into service, as, otherwise, any one component not in operation can render the machine useless.
3
Commissioning equipment: By the needs of production, re-adjust the extruder’s temperature, pressure, and other parameters to guarantee that the equipment should be able to normally produce required multi-layer co-extruded sheets.
4
Feeding and Extrusion: According to formula feeding various raw materials into the extruder, extruding through the extruder to forming multi-layer co-extruded sheet.
5
Laminating and cooling: The multilayer sheets are extruded through the die head of the lamination structure, stacked together, and then cooled and cured through the cooling device.
6
Cutting and packaging: Cut and pack the multilayer co-extruded sheet, and the final product is ready for use in any application.
7
Cleaning and maintenance: Clean and maintain the equipment after production is over, so that it may be continued for a long time in stable operation.
