Design of automatic unscrew thread injection mold for plastic connect pipe
Threaded plastic parts are common. There are two types of threads on the plastic parts: external and internal. The external threads with low accuracy are often eject by a side core pulling mechanism. Internal thread has two structures: forced ejection and automatic unscrew.

Design guide for the air venting system of injection molds
Whether the mold is set with an air venting has a great influence on the quality of plastic parts. For thin-wall plastic parts, small plastic parts or precision parts, the air venting is a crucial point. And in the same plastic part, the part away from the gate position needs to be designed with air venting.

Classic double ejection mechanism return pin + stop pin + spring combination
Double ejection is a common method of ejection system. This method is used to form plastic parts with undercut. When the lifter cannot be used and the slider pops up. In order to better ejection the product, or to avoid gate strain. Sometimes in order to meet the automatic ejection of the plastic part, it is necessary to add another ejection action.
