Q:Napping needle valve type hot runner gate part of what is the reason? Do you have any expert answers?
Needle valve type hot runner hot runner is high precision, the valve needle is one of the important components, effect of the needle valve material of hot runner system can not be ignored. As is known to all, the needle valve type is mainly the valve needle in the non-stop switch closed, thus controlling the feed and shut down.
Q:Injection mould hot runner system needle taking needle tool
The needle system of each hot runner company are different, the heating needs of general, pull out, because the structure is not the same, the use of tools are not the same, some companies do their own fixtures. Is the best request to the hot runner company. Let the staff training
Q:How to set the injection molding parameters of the needle?
After opening the needle valve and the injection linkage switch, as long as the bolt is drawn forward, the needle valve automatically retreats; the end of the discharge valve automatically resets and seals the gate.
Q:Needle valve hot runner Road, needle valve does not move, what are the reasons?
You pull the valve needle, because the needle is too tight, the head of the needle pulled out of it.
Q:If the material selection is not appropriate, long time production, will cause wear of the valve needle, some suppliers use inferior needle valve, or valve needle without cutting, non professional technology, can easily lead to the valve needle top is not smooth, resulting in gate galling phenomenon, the effect is not good, the final effect the quality of products. I hope I can help you
That's what it says. It depends on the material you formed, but I think it's safer in the 0.3 wire.
Q:After the needle valve sealing, how to solve the cold material?
In general, plastic parts should be set at least three or four shots to be more scientific.
Q:The hero can help solve the valve pin, hot runner, into the gate, white spots problem?
I'll give you a few suggestions, 1 valve needle valve needle end temperature, the temperature is too high will the glue burned 2, valve needle back and speed, when the back end of the needle valve will air the 3 mold thickness, temperature effect of gate region will be great, especially cold shear heat hot nozzle at the front end of the 4, this is very important, 5 hot tip white material cannot do without these problems point, hope this is helpful to you.
Q:How to use the needle type oil cup
Directly in the cup Riga with oil, let it drop on the line
Q:Is the injection pressure tight after the valve pin closes?
In the process of injection molding, solution and shrinkage because of cooling, but because the screw to move slowly forward, so that the material in the tube to melt into the cavity, to supplement the needs of shrinkage, called pressure. It means to prevent product shrinkage, with pressure if production is stable. The pressure can also adjust the product size, without weld line
Q:How long is the needle length of the needle valve?
Hot runner company should pay attention to the problem, they will define the length, thickness and so on according to the die drawingThis depends on the size of your mold, the thickness of the cylinder height, the thickness of the flow plate, and the length of the hot mouth, as well as the needle valve to reach the location of the product and so on, to be integrated calculation. There is no fixed sizeI hope this will help you
