Product Description:

Electrical threading PVC conduit pipe production line

 

 

PVC double pipes production line Description:

The pvc groove extrusion line is equipped with conical double screw extruder.

With this machine, the line can achieve a high-efficient production.

 

PVC double pipes production line Application:

The final products are widely used in protecting wires and cables in daily life or industry and construction.

It has the advantages of wear-resisting and moisture proof so it can make wires and cables safe.

 

PVC double pipes production line Process flow:

Raw material+additive→mixing → conveying feeding → force feeding → conical double screw extruder → "one mould two pipes"mould → calibrator → double spray vacuum calibration tank → ink printer → double belt haul-off → double uplift cutter → double pipe rack → finished product inspecting&packing

Q:How to choose the mould of the cable extruder? Ten
Depending on your specific specifications, if XLPE is insulated, extrusion die with small touch line, set on the use of cable diameter, large core conductor than a few tenths of good, if you like to use 70 square tube extruding mold insulation of the conductor element some is big 1 can be set according to the touch, the tensile ratio calculation,
Q:Plastic double screw extruder, pumping air will accumulate material, how is it going on?
Adjust the assembly and check the exhaust block
Q:PVC jacket material in the production of fiber optic cable products,
Or the outer lubrication part of low molecular weight is replaced by macromolecule lubrication
Q:Cable extruder how to match the mold, how to calculate the formula, ask the master pointing
Look at what you have in the form of mold, extrusion, drawing, or half pipe
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:Taper twin screw extrusion machining of plastic masterbatch? What ancillary equipment do you need?
Can, but need feeding machine and related auxiliary mixing granulator, the cost is not low, but the effect is less than double make flat, because itself is not suitable for the design of double cone, adjustment of the formula is the key.
Q:The working principle of an extruder
What is the working principle of an extruder?:Screw with specific shape,Turn in a heated barrel,It will be delivered from the hopperThe plastic is pressed forward, allowing the plastics to be uniformly plasticized (i.e., melted)Through the head and different shapes of the mold, the plastic extrusionA continuous plastic layer of various shapes, extruded on the core and cable.
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 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:What are the two types of extrusion?
Extrusion? The extruder. The extruder is divided into single screw extruder and twin screw extruder, and the twin screw extruder is divided into two parts: flat, double and cone.
