Q:How can I see a needle valve in plastic products?
Do good needle type mold, the glue inlet port is generally lower than the product surface, in front with no obvious signs of the case can be used to identify the surface color, into the plastic needle valve mouth is used with cooling gel, ambient temperature will be higher than the nearby, slightly shiny.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:How to use the needle type oil cup
Directly in the cup Riga with oil, let it drop on the line
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: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: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: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 system is not exactly the valve matrix how to do?
Is the water level higher?. 1: check the air pressure is sufficient. 2: check whether the air leakage.
Q:How does a sequential needle valve work in a hot runner?
The timing needle valve controls the injection of plastic by controlling the opening and closing times of the valve needle. General car door panels, car bumpers and so on must be used timing needle valve, of course, not demanding.
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
