Operating Procedures for Sheet Extrusion Lines. Sheet materials are increasingly being used in everyday life, serving as decorative panels for vehicles, imitation non-slip mats, and in the food industry. In addition, plastic sheets find applications across industries such as manufacturing, commerce, and construction. Common types include PVC sheets, PU sheets, and PE/PP sheets; collectively, these are classified as plastic sheets. There are also two other categories: silicone sheets and rubber sheets—though silicone is, in fact, a type of rubber. Plastic sheets are produced using plastic extruders, while rubber sheets are manufactured with rubber extruders. Whether operating a plastic extruder or a rubber extruder, proper maintenance and adherence to safety protocols are essential.

Operating Procedures for Sheet Extrusion Lines. Sheet materials are increasingly being used in everyday life, finding applications in vehicle interior trim panels, anti-slip mats, and the food industry. In addition, plastic sheets are widely employed across industrial, commercial, and construction sectors. Common types include PVC sheets, PU sheets, and PE/PP sheets; collectively, these fall under the broader category of plastic sheets. There are also two other major categories: silicone sheets and rubber sheets—though silicone is, in fact, a type of rubber. Plastic sheets are produced using plastic extruders, while rubber sheets are manufactured with rubber extruders. Whether operating a plastic or a rubber extruder, proper maintenance and adherence to safety protocols are essential. The objectives of these maintenance and safety procedures are threefold: first, to extend the machine’s service life and minimize malfunctions; second, to ensure operator safety and prevent injuries; and third, to achieve high‑quality products with excellent surface smoothness. Below, we will review the safety operating procedures for sheet extrusion machines.

1. Before starting up, inspect both the electrical and mechanical components of the equipment; only proceed with production once you have confirmed that everything is in proper working order.

2. Pre‑production preparation: Operators must wear appropriate protective gear to prevent burns. Preheat the press rollers to the specified temperature in accordance with process requirements. Verify the water supply and fill the hopper completely.

3. Start-up and Production: Operators shall remain focused, measure the sheet thickness and width, and promptly adjust the calendering speed and nip gap to ensure uniform sheet thickness. Surface scratches, lumps, or uneven edge trimming are not permitted.

4. When rolling, ensure uniform size and a smooth, neat surface.

5. If equipment malfunctions during operation, stop the machine and notify maintenance personnel for inspection and repair.

6. Diligently maintain all production records and shift handover logs.

7. After completing the work, clean the equipment thoroughly, turn off the power, and tidy up the work area.
