Unscrewing versus Jump Thread Mold Design

There are 2 different methods used to eject a cap or closure having a thread from an injection mold: unscrewing thread and jump thread method.

The cheapest and simplest mold to make is the jump thread which uses a stripper ring to eject the part off the mold. Cycle time is short compared to an unscrewing thread mould. The disadvantage, however, is that the part will not perform as well in the field compared to a part formed using an unscrewing mold. In other words, the cap or closure will not be able to hold a tight torque force on its container so should only be used in applications where the physical demands are light such as a storage container used in the kitchen.

In regard to a thread formed using an unscrewing mold, the advantage is that the cap or closure forms a robust thread which almost guarantees a fail proof connection to its container.  Unscrewing molds are used for closures that use stiff resins such as polycarbonate or on containers that have demanding physical requirements such as a high internal container pressure.

Unscrewing molds for caps and closures are very difficult to make because of the rotational and linear movements of particular components inside the mould. However, with our extensive experience we can manufacture an unscrewing mould that will work for the expected life of the mould from the very first shot.

In Mould Closing Mechanism

An in-mould closing mechanism on the mould saves production time and costs by closing every flip top cap in the mould before part ejection eliminating the need to manually close each cap.

We have proven in-mould closing design mechanisms which are activated the instant the mould starts to open.  This means there is minimal time added to the overall cycle time. They can be operated by air or hydraulics depending upon customer requirements.
