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
I'll give you a few suggestions, 1 valve needle valve needle end temperature, the temperature is too high will the glue burned 2, valve needle back and speed, when the back end of the needle valve will air the 3 mold thickness, temperature effect of gate region will be great, especially cold shear heat hot nozzle at the front end of the 4, this is very important, 5 hot tip white material cannot do without these problems point, hope this is helpful to you.
Oh, that I had many at home, should I be treated up to the problem of the people, the beginning of our company is BYD because it helped them deal with YUDO hot runner, and later to do our own, sometimes there will be such a problem, although every time but no fix a method to solve this problem forever,
