- 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: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: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: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: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 valve needle and valve relationship, the gas will be sealed small plastic valve will have a small possibility?
- 1. pressure is not enough, the normal working pressure should be 5bar.
- Q:Working principle of needle valve type oiling cup
- The working principle is very simple, there are like you a look to understand, D is part of a cup, the cup is the top cover, the middle from the top to the bottom through a needle valve, the cup cover is bending spring, pressure spring pressure to the middle of the adjusting nut to adjust the adjusting nut to the top of the needle valve at the lower end of the oil outlet opening.
- 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:After the needle valve sealing, how to solve the cold material?
- The remaining part is the fourth stage (also called the end section). For the plastic parts with simple structure and low appearance quality, the three stage spraying process can be adopted.
- Q:How to set the injection molding parameters of the needle?
- the end of the discharge valve automatically resets and seals the gate.
