Vertical injection molding machine in the semi-automatic state, not sol, and sometimes sol is very slow, seems to be very difficult, and sometimes simply do not turn. The problem is that it occurs during normal use, so the temperature should be fine. The parameter should be OK, too. I removed the screw and cleaned it. There was no foreign object. Under manual operation, the sol is very smooth. Consult an expert.
Mainly back pressure problems, a lot of injection molding machine, manual adhesive and automatic adhesive in the back pressure is not the same
This kind of situation, see what material is used, if it is sticky material stronger, it is recommended to reduce back pressure, may also be a part of the temperature is broken. The temperature at the end of the back should be a little lower. What material would you like to tell me?. Try to increase the pressure and speed of the feed back.
I have encountered such a thing, I analyze the vertical machine tonnage is small, PC material excellent, too sticky. If it's ABS, PVC, PBT and other materials, that's OK, right?
First of all, you can look at you in the melt, screw rotation, the system pressure gauge to meet the pressure you set, if not achieved, that is, the system pressure is out of orderAnd then you are in the process of melting, whether there is abnormal sound, if there is the adhesive, motor seat inside the bearings damagedNext, look at your material is doped with excessive toner and so onFOMTEC plastic, I hope to help you
1, back pressure is too big, should be appropriately reduced2, check whether the inlet cooling water is unobstructed or the glue mouth is agglomerated3, screw slide, with hard point material pass the cylinder4, the use of shooting, retreat and injection of two functions, try a few times back and forth.Injection molding machine, also known as injection molding machine or injection machine. It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. It is divided into vertical, horizontal and all electric type. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity.
