Q:What should be paid attention to in the daily maintenance of the extruder?
Extrusion machine regular maintenance mainly has these aspectsdrive system(1) check the temperature rise of motor and oil tank, whether the bearing is overheated locally, the abnormal noise of motor and gear, oil leakage, radial circle of oil filter and spline shaft, and the contact gap with the end of screw.(2) regularly clean the oil filter and remove the dirt at the bottom of the tank, and lubricate the lubrication points regularly.(3) the new gear box has been filled with gear oil, and new oil will be replaced every 4000 hours after the operation.
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:How to adjust the 65 screw gap in the extruder?
That's the tune.This should be practical learning. The outlet plane of the barrel is about 3 mm in diameter.
Q:Taper twin screw extrusion machining of plastic masterbatch? What ancillary equipment do you need?
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:Extrusion machine operating procedures, specific points, thank you!
6, the speed from low to high, added to the normal speed, is strictly prohibited high-speed car, observe the instrument on the current value and temperature is normal, in case the current is too large, cause the heater to burn.7, when lifting the disk, we should pay attention to the limit of the rise and fall, not too high or too low, when there is an electrical limit, shall not exceed the limit.8 when feeding to the hopper, be careful not to enter the metal, and do not use a screwdriver or a metal bar to poke the plastic into the screw.9 check the dry test machine, should be equipped with rubber insulation plate, otherwise, no driving.10 before driving, should check whether the ground location is good, grounding resistance should be measured regularly, not higher than 4 Europe; equipment whether there is noise and other anomalies, if there is a problem, repair and reuse.
Q:What impact does the extruder vacuum pump open or close on the extrusion product?
If the vacuum pump is opened, the air in the extruded product will be removed and the product material will be more closely packed. If the vacuum pump does not open, it may cause bubbles in the extruded product.
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.
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.
Q:Why do screw extruders often extrude light red plastic products?
Cause this situation. Please clean the hopper thoroughly. The screw is also drawn out and cleaned up. It should be easy to solve.
