The operating skill of the extruder(1)

When making different plastic products, the operating points of the extruder are different, but they also have their similarities. The following is a brief introduction to the same operating steps and key operating points of the extruder when extruding various products.

1. Preparation before start-up（extruder)
(1) plastics for extrusion molding. Raw materials shall meet the required drying requirements, and further drying is required if necessary. The raw materials are sieved to remove agglomerates and mechanical impurities.(extruder)
(2) check whether the water, electricity and gas systems of the equipment are normal, ensure that the water and gas circuits are unblocked and leak free, whether the electrical system is normal, and whether the heating system, temperature control and various instruments work reliably; Conduct low-speed test run of auxiliary engine with no load, and observe whether the equipment operates normally; Start the vacuum pump of the setting table and observe whether it works normally; Lubricate the lubricating parts of various equipment. If any fault is found, it shall be eliminated in time.
(3) install the machine head and setting sleeve. Select the head specification according to the product variety and size. Install the nose in the following order.
