PVC can be produced in one of two forms: rigid and flexible. The plastic PVC extruder serves as an ideal means of producing PVC parts and products. The process is efficient and enables virtually continuous production – resulting in short lead times and reduced costs. Most of the extrusion takes place using screw extruders.
How much do you know about the plastic PVC extruder?
What should be considered when designing the head of the plastic PVC extruder?
How to control the temperature of plastic PVC extruder?
1.The shape of the channel for molten material should be a smooth transition, which is conducive to the material flow. To prevent material retention and decomposition due to overheating, the shape of the channel of the plastic PVC extruder should avoid sudden expansion or contraction and be streamlined as much as possible, not forming dead corners.
2.The head structure of plastic PVC extruder helps to build pressure on the melt material, make the material tight, and eliminate the seam line at the confluence of the material flow. Therefore, the cross-sectional area of the material flow channel should be gradually reduced, thereby exerting pressure on the melt.
3.Under the condition that the strength is satisfactory, the plastic PVC extruder should have a compact structure, few parts, light weight, easy disassembly and assembly, and the shape should be as regular and symmetrical as possible to facilitate the design and installation of the heating ring and adjustment during operation.
Fourth, the choice of head material should take into account wear resistance and corrosion resistance. The part of the machine head in contact with the material should be highly polished to prevent the material from sticking, and tend to be cleaned. Therefore, steel with higher hardness or alloy steel with suitable composition is generally selected, and the relevant structures are polished or plated with nickel and nickel.
1.The plastic PVC extruder is equipped with a single screw to achieve the best plasticizing quality.
2.There will be no coke in the normal field of application;
3.Under the same conditions, the performance of this device is 50% higher than that of other brands of the same type;
4.The plastic PVC extruder uses high quality materials and advanced processing technology, so that the plasticized products can reach more than 10,000 tons.
5.The temperature controller can ensure that the hot oil flows at the best speed at a constant temperature to achieve the best heating function;
6.The plastic PVC extruder is equipped with strong magnetic frame, which can remove magnetic substances;
7.All electrical components are imported brand products, which make the control system safe and reliable.
The water temperature of plastic PVC extruder should generally be 50-60 ℃. If it is too low, the strip can easily break, and if it is too high, it can easily stick. It is best to add half of the hot water when starting the machine. It is transported in the machine for some time and then automatically cut into pellets after the water temperature has risen so that the strips do not break.
Zhangjiagang YaTong Machinery Co., Ltd. is committed to offering the most suitable plastic PVC extruders at a reasonable price and everything necessary to meet customer requirements.
