Q:Why can hot runner needle valve be blocked?
May be a small needle valve, or is not standard and not with the nozzle aperture valve needle understanding.
Q:How to set the injection molding parameters of the needle?
the end of the discharge valve automatically resets and seals the gate.
Q:I put the motorcycle carburetor electronic enrichment valve needle hole is blocked, there is no harm
The manufacturer takes full account of its use in its design. Maybe you're curious. There are many original motorcycles, and we also have them refitted. The same curiosity as you do.
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:Hot runner mold valve needle sealing is lax, what are the reasons?
The main reason is that the cylinder pressure is not enough. Two the injection quantity over three, low temperature hot nozzle, four valve seal leakage, valve needle valve needle sleeve wear Arno, wear after lead carbide glue leakage valve needle movement is not in place, the size of the mold is not precision.
Q:Does the needle valve hot runner have adhesive problems? What are the possible causes?
ExistingWe asked coreter hotrunner maintenance customer servicePossible reason: the valve needle does not emit too much heat.Handling: reduce hot nozzles and gatesThe temperature increases with cooling time.
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:Mold glue is how the air valve needle
The hot plate of the needle valve has operation instructions on it. If it is not clear for a long time, see if the hot runner leads out the interface. Is there any mark gas IN/OUT?If not, (usually two groups, only one group and one group)
Q:Hot runner valve needle in the molding, why will retreat?
The following reasons may cause the needle to recedeThe plastic pressure is greater than the cylinder pressure, causing the needle to recede
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.
