Q:Napping needle valve type hot runner gate part of what is the reason? Do you have any expert answers?

Needle valve type hot runner hot runner is high precision, the valve needle is one of the important components, effect of the needle valve material of hot runner system can not be ignored. As is known to all, the needle valve type is mainly the valve needle in the non-stop switch closed, thus controlling the feed and shut down.

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: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: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:Needle valve hot runner outlet hole shrink what is the reason?

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:What's wrong with the sealing ring at the needle valve of the spray gun?

If the sealing ring break not leak does not affect the pressure, spray a shares is because the last time you painted not wash or spray gun, the valve needle sharp deformation, if often run out of the gun after cleaning will cause the spraying effect is not good, long lance clog, preferably after use with clean water that day!

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:Needle valve hot runner Road, needle valve does not move, what are the reasons?

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:What is the hot runner valve needle?

There are DME (USA), INCOE (USA), MOLD-MASTER (Canada - hot runner), HUSKY (Canada) and so on

Q:How many times can the hot runner valve needle be used?

Needle valve has good or bad, generally have quality requirements of the needle valve, the basic use of the industry standard disk needle valve, the international standard moldThe valve needle surface hardness of HRC60-62, titanium, with non stick material, high abrasion resistance, continuous use up to 1 million times,
