What is the air pressure of the needle valve hot runner?

The air pressure is large, of course, it is helpful for the sealant, but you can do it empty, you have to understand why the product is not good, the force that causes the gas needle not to advance to a low is the pressure from the plastic, 1 injection pressure, 2 the deformation resistance of the cooled rubber material, overcoming these two reasons will help you solve similar problems.

In this case, we don't see the specific shape and size of the product, and we can't accurately judge how much air pressure should be used. In such a situation, it may be that the needle valve structure is unreasonable. As a result, the product cannot be returned normally during injection molding.

6-8 kg is about the same, we couldn't use it before, and finally found the after-sales service of the Geruntai hot runner.

Depending on the situation, the pressure of the oil pressure is large (some plastics are cold quickly, and the hardness requires a lot of pressure), and the air pressure is generally a few kilograms of force.

I remember that the kinetic energy was below joules, and the single air pressure could not be judged, and the main thing that determined the power was the air pressure and the amount of air outlet.

As it stands, what is the atmosphere of a toy bb gun? Isn't it also regulated! Accordingly, it is no longer meaningful to discuss the issue of unregulated multi-atmosphere pressure.

No ventilation or insufficient air pressure, insufficient flow channel temperature, blocked or broken needle valve.

You need to have a pressure reducing valve, adjust it to 5 kg. Otherwise, the pressure is unstable.

kg The pressure of the air compressor you choose is within the range that your equipment needs, this air compressor also has a pressure difference, the low pressure starts to pump at about 4 kg, and the 7 kg stops, this pressure is no problem, but there is a flow problem, the volume flow of the compressor is 40 liters per meter, so how much flow does your gas equipment need, the flow rate of the gas equipment is less than the flow rate of the air compressor.

The pressure can be adjusted, and if you want to install more, you need an air pump, and the air is sufficient.

The sequential valve is not a general needle valve type, the full name is: sequential needle valve hot runner. His principle is to control the pouring time at the pouring point to control the weld marks.

For example, for example, a bumper is played with 5 points, generally poured from the middle, when the plastic flows to the edge gate, and then open the valve pin at the edge to pour, according to this principle to control the weld marks, the sequence valve is the timing needle valve, the purpose is to control and adjust the weld marks. It is made of an ordinary needle valve type and adds a sequencer to achieve the purpose of control and adjustment.

The hot runner sequential valve can be said to be separated by two parts, one part of which is linked to the injection machine that has been kept at a high temperature and is in a liquid state. When a certain set time is reached, it will automatically open and flow into the cavity, and when the pressure holding is completed, it will close and isolate from the cavity, and then wait until the cavity is cooled and open for another cycle.

The solenoid valve signal is used to receive and control and the needle valve is pushed by the hydraulic cylinder or pneumatic cylinder to achieve sealing.

The answer is satisfactory, please give a reward and satisfaction, thank you!

Generally, the car is completely OK, four-level pass, of course, if you want to be very standard, look at the vehicle nameplate before and after the vehicle standard air pressure, adopt it, thank you.

Hello, the size of the glue inlet point of the hot runner mold cavity is determined according to the size of the product and the number of points. Hope it helps.
