Q:Computer case shell plastic is injection molding or extrusion molding?
1. injection molding2., the structure is relatively complex, high appearance requirements. Extrusion does not meet requirements3. most are: ABS, ABS+PC, PP and so on4., according to color requirements granulation - drying particles - filling the mold ---- debugging injection molding machine ---- injection molding production - after the selection of finished packaging (if silk screen requirements, but also the need for silk screen)
Q:What is the principle of the 45 extruder machine?
The principle of the extruder is the theoretical process of heating, melting and mixing in the process of plastic conveying, including solid conveying principle, melt transportation principle, mixing principle, and solid bed crushing process, etc..
Q:What is the three layer coextrusion blow molding machine for blow molding of plastic bag tension formula,
Plastic tensile testing without tension is strong that said, you should be the low tensile strength, tensile strength for 2 kinds of films, one is the transverse tensile strength, a longitudinal tensile strength, is a reflection of the tensile properties, the tensile strength of the plastic bag if you low, because your choice of materials is not brittle material or toughness (PE/PP/PVC/PET/PBT/PC do not know or what material) if you insist on using this material, make plastic bags, you can modification method by crosslinking, adding additives, improving formula, to achieve the goal, the specific situation you need to find a degree in Polymer Science plastic engineer, they will tell you.
Q:Basic parameters of extruder screw
2. The ratio of the length to diameter of the screw, the length of the screw L/Ds and the ratio of L to the diameter of the screw Ds is called the ratio of length to diameter. When the other conditions are constant (such as the diameter of the screw), increasing the ratio of length to diameter means increasing the length of the screw. The L/Ds value is large and the temperature distribution is reasonable, which is beneficial to the mixing and plasticizing of plastics. At the same time, the heating time of the plastic in the barrel is longer, and the plasticization of the plastic will be sufficient and more uniform. So as to improve the quality of machine plastics. If the plastic quality requirement is constant, the rotation speed of the screw can be increased after the ratio of length to diameter increases, thereby increasing the extrusion amount of the plastic. However, too large length diameter ratio, power consumption will increase the screw, and the screw and barrel of the processing and assembly of chicken more difficult; the possibility of screw bending will increase, will cause the abrasion of the screw and the inner wall of the cylinder, reduce the service life. In addition, the heat sensitive plastic, large diameter and long retention time than thermal decomposition, the plasticizing and impact plastic extrusion quality. Therefore, in the full use of the advantages of increasing the ratio of length to diameter, the selection should be based on the physical properties of the processed plastics and the quality requirements of the products.
Q:PVC jacket material in the production of fiber optic cable products,
Is the place where the material is easy to burn rough? Add stabilizers and lubricants appropriately.
Q:Extrusion blow molding machine, storage or continuous type good?
and material in the screw for a long time to use the storage type is also in order to meet the demand for raw materials productsIf you are doing small things, your hourly output will not consume the maximum hour.
Q:Our factory has a continental 590 control DC motor used in extrusion machine,
I've also encountered (missing a pulse alarm), and finally checked out is a SCR triggered, impassability, you can try
Q:Who knows the temperature regulation method of the extruder?Any information will do
1, extrusion methodAccording to plasticizing methods: dry extrusion and wet extrusionPress the way: continuous extrusion and intermittent extrusion2, characteristicsContinuous production, high efficiency, simple operation, wide range of applications [Edit] paragraph extrusion molding equipment 1, the hostExtrusion system: composed of screw and barrel, it is the key part of extruder. Its function is to melt plastics, quantitative, constant pressure, constant temperature extrusion of meltDrive system: drive the screw to increase the required torque and torqueHeating and cooling system: guarantee the temperature of plastic and extrusion system in molding process2 auxiliariesIt is composed of head, setting device, cooling device, traction device, coiling device and cutting3 、 control systemIt consists of electric apparatus, instrument and actuating mechanismPurpose: to control the main and auxiliary motor, in order to meet the demands of speed and power; control main engine temperature and pressure and flow, to ensure product quality; to achieve automatic control of the extrusion unit, ensure the coordinated operation of main and auxiliary equipment. [edit this paragraph] extruder extruder overview of plastic extruder is the host, it consists of extrusion system, transmission system and the heating and cooling system.
Q:PLC based extrusion machine control system design graduation thesis and PLC based injection molding machine control system graduate 20
Tip three: select the topic according to the documents. Literature is the foundation of support, enrich the direction and point of view, but also can reflect the research result, the author embarks from the existing literature, topic and refine the title, became the third skills.
Q:Why single screw extruder is controlled by high school and low?
What is controlled by high school? I can't answer the question without saying it
