How much is the ejection rate of injection molding machine?
Under normal circumstances, 3---10 almost, special when the special appropriate tune
The amount of ejection is dependent on the mold and the plastic material.First look at the first mock exam after injection, the material handle has no salivation, if any, can be set to shoot back, slowly, starting from 2mm, to appear without salivation. If the material handle no salivation, absolutely no need to design back.Because the shooting back has drawbacks, shot back at the nozzle will shoot back, into the air, the air will contain water, big shot back often caused by material moisture, surface appearance of silver.If I found both salivation, but increase the shoot back position and feed tide. You can lower the temperature and the back pressure will decrease.
Generally transferred to 4, to 6 can be, I hope my answer will help you - Switek
