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: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:The hero can help solve the valve pin, hot runner, into the gate, white spots problem?

Field analysis is required!It's OK to use our hot runner

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:Hot runner valve needle broken inside how to do?

Then heat the drain plate and remove the needle from the distributor with the needle sleeve. Then the muskets firing valve needle sleeve, the glue burn clean, it can take out the needle valve. Hope to help you.

Q:Working principle of needle valve type oiling cup

I know this, I want to make a joint in the oil filler, can solve the leakage problem of inclined tubular Jiagen, but no drawings, do not know the specific circumstances not joint design

Q:Hot runner mold valve needle sealing is lax, what are the reasons?

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 runner is the first and the runner is second, and the product is about third when it reaches 90%.

Q:How does a sequential needle valve work in a hot runner?

Controlled by Timer, control and solenoid valve.General car door panels, car bumpers and so on must be used timing needle valve, of course, not demanding.

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.
