Conical twin screw plastic extruder:

Features Specifications:

1. Model SJZ series conical twin screw extruder is a kind of special equipment for extruding PVC compound. With different kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material and granulation.


2. The conical twin screws have applied oil cooling system. Barrel is cooled by special wind cooling system.


3. The conical twin screw extruder system has applied special computer control. According to customers requirements, most reasonable structure of conical twin screw can be made so as to achieve best plasticity performance and material quality.


4. The conical twin screw is made by high precision special digital screw miller; extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut.


5. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure.


6. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± 1degree.

Q:Why is the connection between the extruder and the switchboard?. The upper and lower three terminals are short circuited
The action should be to require three simultaneous electricalOr a two way backup
Q:Computer case shell plastic is injection molding or extrusion molding?
It must be injection, you see that hole, that button, can not squeeze out.
Q:PVC extrusion machine extrusion stone floor no pressure, what reason?
PvC stone floor extruder pressure is adjusted by the screw and die head
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:What is the adjustment method of China's extrusion machine die?
(5) sense of mold: it is the method of experience versus mold. Feel the thickness of the plastic layer by hand and adjust the mold. The utility model is suitable for the outer protective layer of large cross section wire and cable.
Q:Equipment is the Changzhou sun extrusion machine,
7042, no tax 9350-9400 yuan / ton, 02TN26 no tax,
Q:1: what is the difference between an extruder and an injection molding machine?
2: injection molding machine, mainly to melt the plastic injection molding process, after the mold injection molding machine outjection. The main products are mechanical parts, containers, household appliances shell.
Q:What is the three layer coextrusion blow molding machine for blow molding of plastic bag tension formula,
The recipe is either too large or too small. Do you mean that the tension is not enough, transverse or vertical?
Q:Wire and cable extrusion machine extrusion die how to quickly adjust the core degree, how can I touch it by hand?,
See section - cross section. Setting adjustment with RPC
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.
