In the picture looks stripper mechanism, where the product is dropped by a plate drawn by the pull plate is fastened to the plate cavity. At an open mold, the core will open for the movement carried by the moving plate. runner or know by heart is also separated from the sprue, because of the undercut at the end of the run ner pin. The products also come loose at the pull out step plates.
The system is relatively inexpensive but only for a simple product of a certain size. If the product has a wide or large diameters and thin walls, so after products on the strip off from the core (male), there is a possibility the product will be deformation (bending).
This is because:
- Vacuum at the upper inner wall of the product
- Large diameter products that produce products cengkaram force on the core component is also large, while the thin wall product is not strong to overcome the vacuum's and grip style.
Deformation is common in the soft plastic material such as PE, PP, etc.
