FAQ


PVC sheet extrusion 

*Q: What’s the price of this machine please?

*A: Dear customer, for each kind of our machines, we have lots of models. 

Generally speaking, we design the production lines according to 

different requirements of different machines from different customers. 

Therefore, the prices are different. So please kindly inform us your requirements. 

For example, the raw material, the output product size, capacity and etc. 

The more detailed, the better. Our Engineers will design a suitable production line for you.

Q:What is the adjustment method of China's extrusion machine die?
(4) lamp alignment: suitable for polythene plastic wires and cables. Use light to illuminate the insulating layer and sheath, observe the upper, lower, left and right sides of the thickness, adjust the screw to the die until it is even, then screw the screws.
Q:Why single screw extruder is controlled by high school and low?
I feel like I didn't explain the problem
Q:1: what is the difference between an extruder and an injection molding machine?
1: extruder, is threaded through the push rod, the plastic die forming process by melting in the forward process. After the extruder products are silk, belt, tube, plate, etc.
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:The working principle of an extruder
The material is moved forward by the extrusion of the screw and the barrel, and the material is fully homogeneous and plasticized in the process of material advance. Then the material is extruded by a certain shape of the die by the die of the die.
Q:Why will the extruder frequency shift stop?
Because the frequency converter is out of order, you can look at the fault record parameters of the inverter.
Q:What is the waste gas produced by the extruder, granulator and mixer?
Do you want water spray, dry filter, carbon adsorption, fan, and discharge? Will that be better, thank you?Chasing the answerIf the exhaust gas contains acid and alkali waste gas (slightly acid base acceptable), there is no need to water spray, the main role of water spray is used to neutralize the acid and alkali containing exhaust gas. The exhaust gas is dry organic waste gas, only dry filter, activated carbon adsorption odor can be discharged.
Q:What impact does the extruder vacuum pump open or close on the extrusion product?
If the vacuum pump does not open, it may cause bubbles in the extruded product.
Q:Does anyone know the operating procedures for the cable 65+120 extruder?
What are the operating specifications for the extruder?One is the equipment instructionTwo is the boot operation specificationsThree is safety instructions and so onThe equipment manufacturer will provide the above
Q:Who knows the temperature regulation method of the extruder?Any information will do
Extrusion molding in plastic processing is called extrusion, using hydraulic pressure in rubber extruder processing in extrusion die extrusion. That itself means that the material through the extruder barrel and screw the function between the side heating plasticization, screw edge is pushed forward, a processing method of continuous head made by various sections of finished or semi-finished products.In the fiber chemical industry is also useful in the extruder to the spinneret for melt spinning. The material, process of extrusion used in thermoplastic plastics and rubber, for batching, granulation, rubber filtration, continuous production, manufacturing various continuous products such as pipe, profile, sheet (or sheets), thin film wire and cable coating, rubber tire, tube noodles barrel, a sealing strip, the production efficiency is high. In the production of synthetic resin, can be used as reactor extruder, continuous polymerization and processing, in rubber industry, the compression ratio of different extruding machine can be used to unmasticated natural rubber of different materials. Compression extrusion machine than some different. [edit this paragraph] the principle of extrusion molding material since the bucket into the barrel, the screw rotates under the action of the cylinder wall and the surface of the screw friction shearing forward delivery to the feeding section in the loose. Forward transport also is compacted; the compression section, screw groove depth, further compaction, while the barrel heating and screw and cylinder wall friction shear, the material temperature rise began to melt, the compression section ends; homogeneous section material uniform, constant temperature, fixed quantity, squeeze out to melt. After a head forming, by setting the product.
