Sharing of Design Methods of Injection Mold Exhaust Slot

12/12/2022 No Comments

During injection molding, there will not be a lot of molten materials oozing from the vent hole, because the molten materials will be cooled and solidified there to block the channel. The opening position of the exhaust port shall not face the operator to prevent accidental ejection of molten materials from injuring people. In addition, the fit clearance between the ejector rod and the ejector hole, the fit clearance between the ejector block and the
