Q:How can I see a needle valve in plastic products?
The needle tip of the valve will also have obvious marks, because the high temperature and the entrance of the glue hole will always be more or less bright or rough than that of the die steel.
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: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
It depends on the material you formed, but I think it's safer in the 0.3 wire.
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 system is not exactly the valve matrix how to do?
3: check aprons are damaged. 4: open the hot runner, check whether the valve needle and valve sleeve between the seepage. Wait。 It's best to see the model,
Q:Hot runner valve needle broken inside how to do?
Hello, you are pulling the valve needle, because the needle is too tight, the needle out of the head of the bar.
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
Q:Needle valve hot runner outlet hole shrink what is the reason?
Because the valve needle is into the gate, the hot runner temperature here is the highest, so the plastic temperature near here is the highest. The higher the temperature is, the greater the shrinkage, so when the product is cooled naturally, the needle valve has the largest shrinkage hole.
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)
