Application of the pipes produced:
electricity wire sleeve, urban water supply and drainage system, agricultural irrigation pipe, underground filtration irrigation and the water supply or drainage system in buildings, etc.
Characteristics of the pipes produced:
Light weight, good performance of shock resistance, high rigidity, corrosion-resistance, cold and hot resistance
Characteristics of the machine:
Mould and Auxiliary Machine: The mould die is of high precision and the mould blocks are changeable. There are two cooling modes to the mould block, by water and by fan. The planetary cutting machine is of high cutting precision; SIMENS human-machine interface control system realizes high automation.
Extruder: The extruder can be designed according to the different materials; HDPE material uses high efficiency single screw extruder, the PVC material uses conical double-screw extruder.
1. Two high efficient co-extrusion single screw extruders
2.It adopts excellent screw and new groove sleeve design,
which makes the extruder with bellow advantages: high plasticization rate,
smooth melt, stable production process,
and enable the inside and outside layer of the pipe to use different materials
3. Corrugation forming block is made by special alloy material. It has high precision,
intensity and outstanding heat emission.
4. Nitrogen treatment of the mould surface. There is wall thickness adjusting device
in the mouth mould and can produce pipes of different raw materials.
5. It has a flaring function, which can reduce the investment and enhance efficiency.6. The production line adopts advanced Simens PLC control system
, with human-machine interface operating system, has high automaticity, easy operation.

- Q: Basic parameters of extruder screw
- 3, compression ratio epsilon, also known as the geometric compression ratio of screw, is the ratio of the volume of the first screw groove to the volume of the last screw groove at the homogenization section. It is determined by the physical compression ratio of plastics - that is, the density of the product and the density of the performance of the feed. The extruder is relatively compressed, the purpose is to make granular plastics fully plasticized and compacted. The selection of compression ratio should be different when different kinds of processing plastics are used. According to the compression ratio, the types of screw can be divided into three types: equidistant, unequal depth, equal depth, unequal distance, unequal depth, unequal distance. Among them, equidistant and unequal depth is the most common one. This kind of screw is easy to process, the contact area of plastic and cylinder is large, and the effect of heat transfer is good.
- Q: extrusion machine prone to coke material, what is the cause? How to improve or solve?
- Is the place where the material is easy to burn rough? Add stabilizers and lubricants appropriately. Or the outer lubrication part of low molecular weight is replaced by macromolecule lubrication
- 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.
- Q: What are the common extrusion molding products?
- Extrusion molding products are as follows:1 、 plastic pipe, for example: water pipe up and down;2, plastic profiles, such as: doors and windows, plastic steel profiles.3, plastic plates, such as: wood plastic doors, plastic doors,4, plastic sheet (sheet and board is the difference between the thickness, thin, thick plate), such as: mobile phone membrane.
- Q: Extrusion blow molding machine, storage or continuous type good?
- The amount of extrusion must be continuous, efficient, and wasteful
- Q: Comparison of injection molding machines and Extruders
- Considerations for extruder use:1, extrusion machine is running forward, avoid reverse2, avoid fasting operation, must heat engine feeding operation, so that can avoid sticking bar (holding shaft) phenomenon3, the extruder inlet, vent hole is strictly prohibited access to iron and other miscellaneous, so as not to cause accidents, affect production4, safe use of electricity, grounding wire5. When the machine is running, it is forbidden to touch the rotating parts such as the material inlet, the material outlet, the belt, the gear and so on6, before using the machine should be injected with lubricating oil, so as not to cause damage to the machineSince the extruder as one of the three synthetic plastic material since the advent of rapid development.
- Q: Why single screw extruder is controlled by high school and low?
- I feel like I didn't explain the problem
- 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: 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: 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,
