Bo machine can also, moderate price, stable performance, I used to produce mobile phones accessories

Q:when the material stored, the screw has been in situ, and will not go back to the set stop position. What shall I do?

When the material storage, you look at the nozzle has no material, if there is no transfer under the pressure, if you look at the material hopper have feed tube material, if there are very thick material in the hopper below the card down to the tube without glue, will have to screw in the back. Not always

Q:Can carbon fiber be used for injection molding?

Carbon fiber can be used for injection molding, and the typical product is CF+PPS.Carbon fibers are difficult to process two times, such as drilling on molded products, plain drills, drilling holes, and drilling bits. Therefore, in the part design to avoid two machining. In addition, as with plastic and glass fiber, and carbon fiber after the screw injection molding machine screw wear increases, the life expectancy was shortened.Global carbon fiber technology and production are still largely in the hands of Japan and the United states. There are less than 20 countries and regions that can realize the industrialization of carbon fiber in the world. There are no more than 12 large-scale production enterprises. Japan, Dongli, Japan, Toho, USA, tektronix,Japan MITSUBISHI Li Yang is the global carbon fiber production capacity of the top four manufacturers, the four respectively accounted for global carbon fiber production capacity of 23.4%, 17.1%, 14.3% and 10.3%, while Chinese enterprises accounted for only 4.3%.The global carbon fiber production is mainly based on PAN based carbon fiber. In 2009, PAN based carbon fiber production capacity accounted for about 96% of the total carbon fiber production capacity of the world. The Dongli of Japan, and Toho MITSUBISHI rayon is mainly engaged in the small tow (24K) PAN based.CF+PPS 160000 yuan / tonFiber production, in 2009 this three accounted for 70.5% of the world's small tow capacity; the United States Zoltek is mainly engaged in large tow (>24K) PAN based carbon fiber production, 2009 Zoltek accounted for the global total capacity of 49.1% large tow.

Q:What an elder brother knows how nitrogen injection is going on. What should I pay attention to?

1. the operator must undergo good safety education.2. operate strictly according to the operating rules of equipment.3., when the valve operation, wear protective equipment: masks, gloves, etc., to prevent frostbite.4. check the safety valve and pressure gauge once a year, check the riot film every two years, check and record the records.5. when the nitrogen emissions, people should stay away from the drain, otherwise, long time suffocate easily.6. in the obvious place to hang around the nitrogen tank "trespassers", "dangerous" and other warning signs.7. freezing on nitrogen pipe, no heavy blow.8. check the nitrogen tank every day and find the problem in time.9. always keep the nitrogen tank clean and free of oil and grease.10. equipment should be cut off for a long time without gas.

Q:Injection molding machine melt when the screw speed is particularly slow, what is the reason for the oil pound pressure is small?

1. check how much screw speed is set when the injection machine is set2. is the temperature setting reasonable? If the solution temperature (barrel temperature) is unreasonable, and the fluidity of the compound is not good, it will appear because of friction, speed is very slow.The above should be the oil pump problem

Q:Notice of injection moulding machine

Injection molding machine temperature rise is too high, five major hazards: the machine produces thermal deformation, oil viscosity decreases, rubber seals deformation, accelerate oil oxidation deterioration, but also make the air component pressure reduction.One of the hazards: causes the machine to produce thermal deformationIn the hydraulic component, the moving parts with different thermal expansion coefficients are jammed because of the small clearance between them, which results in malfunction and influences the drive accuracy of the hydraulic system, resulting in the poor quality of the parts.Hazard two: reduce the viscosity of the oilThe high temperature rise of the injection molding machine will lead to lower viscosity of the oil and leakage increase. The volume efficiency of the pump and the efficiency of the whole system will be significantly reduced. As the viscosity of the oil decreases, the oil film of the moving parts, such as the slide valve, is thinned and cut, and the frictional resistance increases, leading to increased wear.Hazard three: deform rubber sealsThe temperature rise of the injection molding machine is too high, it will deform the rubber seal, accelerate the aging failure, reduce the sealing performance and service life, and cause leakage.Four of the hazards: to accelerate the oxidation of oilThe temperature rise of the injection molding machine is too high, it will accelerate the oxidation of the oil, precipitate the asphalt material, and reduce the service life of the hydraulic oil. The precipitate blocks the damping orifice and the slit valve opening, causing the pressure valve to stop and cannot move, and the metal pipe lengthens and bends, and even breaks.

Q:What's the meaning of "loosening and retreating" before injection machine?

In the gum before the action, do plastic pumping action, that is, before the release of pine, in the volume of gum after doing loose retreat, that is, after the pine back, which is more commonly usedBack pressure is to control the back storage speed, big barrel is in a more solid material!

Q:How many solenoid valves are there on the injection molding machine?

The working principle of solenoid valve, solenoid valve in a closed chamber, at different locations to open a hole, each hole leads to different pipeline, the middle valve chamber, both sides are two electromagnets, which face the magnet coils body will be attracted to which side, different row the oil control valve moves to block or leak hole, and an oil inlet hole Shichang opened, hydraulic oil will enter the drain pipes of different, then the oil pressure to push the piston oil just, piston and piston rod, the piston rod drive mechanism moving. Thus, the mechanical movement is controlled by controlling the electric current of the electromagnet. Cxmeinai.1688 , I hope I can help you!

Q:How much is a new injection molding machine, mainly mobile phone shell?

Look at the brand, 100T models, domestic cheap, prices do not know
