Is there anything special about the speed of the screw of the injection molding machine Jinyang ?

Which low-pressure injection molding machine is better, it is said? Suzhou Conig provides customers with complete solutions from product application evaluation, efficiency cost analysis, sample production, sample development, as well as diversified mass production equipment and mass OEM. In particular, we have accumulated rich experience and technology in solving the encapsulation of sensors, waterproof connectors, micro switches, printed circuit boards (PCBAs), wiring harnesses, polymer batteries, communication antennas, and other products in these industries.

Better provide personalized service to customers. Suzhou Conig offers a wide range of low-pressure injection molding machines! Low-pressure injection molding machines, etc.!

a. The rotation speed of the screw directly affects the shear of the plastic in the spiral groove;

b. The small screw groove is shallow and absorbs heat quickly, which is enough to promote the softening of the plastic in the compression period, and the friction heat energy between the screw and the barrel wall is low, which is suitable for high-speed rotation and increases the plasticizing capacity;

c. Large screws should not rotate quickly, so as to avoid uneven plasticization and excessive friction heat;

d. For plastics with high heat sensitivity, if the screw speed is too large, the plastic will be easily decomposed;

E. Usually the screws of various sizes have a certain speed range, generally 100 speeds'150rpm;Too low will not melt the plastic, and too high will scorch the plastic.

It is necessary to see whether the screw current is large or small when the screw speed is slow. Combined with the screw current to judge, it is better.

The screw current is large and the speed is slow, which is undoubtedly the large load of the screw and the low temperature setting of the process, resulting in slow speed, and then small shear, more and more immobile, slow speed, special attention should be paid to current overload, burn-out frequency conversion or motor.

The screw current is small, the speed is slow, there are many problems, it may be that the temperature is set too high, it may be that the pressure of the oil pound you said is too small, and the back pressure will retreat after the big pressure, or it may be that the control system is not set up reasonably, the response is too slow, the adjustment is not timely enough, and the PID parameters should be modified.

1. Whether the pressure velocity (flow) of the sol is set correctly.

2. Whether the sol method is set correctly.

3. Whether the stability of the barrel is set reasonably.

4. Whether the sol solenoid valve is stuck (use a thimble of about 3mm to push the valve core on the side of the sol solenoid valve into it to see if it can be normal.)

1. The temperature is too low, 2. The pressure speed is too small.

3. Too much back pressure.

4.If other movements are also slow, there is a problem with the pressure and speed valves.

1. The screw turns to see the size of the pressure gauge, if it is large, the back pressure is too high or the material temperature is low 2, it is still not good, the sol valve is stuck, 3mm poke the valve core or remove it for cleaning 3, the gauge pressure is small, the storage speed, the pressure setting is low, and the system parameter setting is low 4, if the pressure is also small during other actions, it is possible to have a small pressure of the oil pump.

1.What is the screw speed when the injection molding machine is set to dissolve?

2.Is the dissolution temperature setting reasonable? If the dissolution temperature (barrel temperature) is not set properly, and the fluidity of the rubber material is not good, the rotational speed will be very slow due to high friction.

The above rule out should be a problem with the oil pump.

First of all, check whether the oil return pipe with a small melt motor has a large oil return, if so, then the melt motor is broken.

Mold clamping time + injection time + storage time Synchronous cooling time + mold opening time + demoulding time + taking out time = full cycle time.

There is basically no restriction on the specifications of customized Jinyang screws, and the drawings are ready for door-to-door surveying and mapping. But it takes about a month to complete the custom, which is okay.

There is no limit, as long as you have drawings or let them come to your door to help you survey, but it generally takes about a month to be ordered.

Goldjoy screw is guaranteed for one year, and any quality problems in one year are free to replace.

The speed of the screw of the injection molding machine is to adjust the preplastic pressure and flow rate of the injection molding machine, and then adjust the back pressure.

The speed of the screw can improve the plasticization of the raw material! It has a good effect on the uneven coloring of flower products! It shouldn't be too fast, too fast will make the product quantity decrease, surface defects, etc.! Generally between 270 and 350 rpm!

Thank you for the trouble to adopt!

It is best to use a screw made of all-alloy material, and the PC material requires the screw to be more resistant to high temperature, corrosion and wear.
