1. Injection molding machine: The injection molding machine is the core equipment for plastic extrusion. It heats, compresses and pushes the plastic raw materials forward by rotating the screw to produce continuous plastic melt. The screw with a threaded shape rotates in the heated barrel to squeeze the plastic sent from the hopper forward, so that the plastic is gradually heated and evenly plasticized. Through the head and mold, the plastic is extruded onto the core. The barrel is composed of an inner and outer barrel. The inner and outer barrels are electrically heated together, acting as a “heat source” for the machine body. In cooperation with the screw, the plastic is crushed, softened, melted, plasticized, vented and compacted, and the rubber is continuously and evenly delivered to the molding system. The screw is the “heart” of the extruder. Only the movement of the screw can complete plastic extrusion. The rotation of the screw generates shear force to break the plastic; the rotation of the screw generates thrust, which makes the broken plastic move forward continuously and thus generates extrusion pressure. The extrusion pressure generates reaction force on the screen plate and other parts where the pressure reaches, causing the plastic to flow and stir, thereby achieving a comprehensive balance in the extrusion process.
2. Extrusion die: The die is a metal cavity of a specific shape used to form the insulation layer or sheath layer of the cable. When the molten plastic passes through the die, it is restricted by the die to form the required shape and size.
3. Cooling device: After the plastic passes through the die, there is usually a cooling device to quickly cool and harden the plastic to form the required cable components.
4. Traction device: The traction device pulls the cooled cable components out of the mold to ensure the continuous production of cable components.
Plastic raw materials are the biggest and long-term cost burden for manufacturing plants. In order to reduce costs, manufacturers of all types of products are eager for a scientific recycling method to maximize the guarantee that corporate profits are not wasted without reason and to ensure the sustainable operation of the enterprise. As we all know, the plug injection molding machine of the power cord plug factory produces nozzle materials every day. So how to effectively recycle and process these nozzles materials ? Leave it to ZAOGE plastic grinder. ZAOGE grinder grind the nozzle materials online immediately and use the nozzle materials immediately. The grinded materials are uniform, clean, dust-free, pollution-free, and of high quality. After mixing with the raw materials, high-quality products are produced.
