What does injection machine mean by "short shoot"?
Short shot is not to go slow glue, injection molding is not filled with the entire cavity, only a small part of filling, next time a little more, so that several times filling, and finally filling, slow the entire cavity. The function is to see if the glue is even. Especially in the multi cavity, you must try this way.
A popular explanation is: in the test mode, because the materials in the barrel for so long, too much dissolved carbonation, put more easily cut waste of raw material, put less gun are not clean, speed is injected into the cavity under the condition of high temperature will be faster than normal, easy to swell that flash into the cavity around the gap is difficult to clean up, clean up the mold cavity more than expected a lot of work, the mold also has a certain degree of injury. So, start with a few shots or a short range, or reduce speed or pressure, to reach the effect of not filling, and then gradually full up until then, this is called short shot, but the local name is different. (it is recommended that the release agent be sprayed at the same time as the short shot)
