Automotive Interior Array Reduction Sheet Extruder Sheet Extrusion Manufacturer>
Automotive Interior Sheet Extruder The following is a brief introduction to the same operating steps and extruder features that should be paid attention to when extruding various products. Operational points. , Preparation work before driving ⑴ Plastic used for extrusion molding. The raw materials should meet the required drying requirements and be further dried if necessary. And the raw materials are sieved to remove agglomerates and mechanical impurities. ⑵ Check whether the water, electricity, and gas systems in the equipment are normal, ensure that the water and gas lines are smooth and leak-proof, whether the electrical system is normal, whether the heating system, temperature control, and various instruments are working reliably. The auxiliary engine is empty and tested at low speed. Observe Whether the equipment is running normally, start the vacuum pump of the setting table, observe whether it is working normally, and lubricate the lubricating parts of various equipment. If any fault is found, eliminate it promptly. ⑶Install the machine head and shaping sleeve. According to the product variety and size, select the machine head specifications. Install the machine head in the following order.
The working principle of the screw extruder of the automotive interior sheet extruder is to rely on the pressure and shear force generated by the rotation of the screw, which allows the material to be fully plasticized and evenly mixed, and then formed through the die. Sometimes an extruder can be used to complete a series of processes such as mixing, plasticizing and molding at the same time, thus enabling continuous production.
The screw is the heart of the extruder and a key component of the extruder. The performance of the screw determines the productivity, plasticizing quality, dispersion of fillers, and melt temperature of an extruder. , power consumption, etc. It is the most important component of the extruder, which can directly affect the application range and production efficiency of the extruder. The rotation of the screw exerts extreme pressure on the plastic, allowing the plastic to move, pressurize, and obtain part of the heat from friction in the barrel. The plastic is mixed and plasticized during its movement in the barrel, resulting in a viscous flow state. When the melt is extruded and flows through the die, it obtains the desired shape and is formed. Like the barrel, the screw is also made of high-strength, heat-resistant and corrosion-resistant alloys. When using a car interior sheet extruder to produce different plastic products, the operating points of the extruder are different, but there are also similarities.
