8470 Material Plastic Mould Parts Collapsible Core Mold Inserts Core Pins

The internal and external threads on the part create undercuts which prevent a simple mold design. Solutions include side action cams, threaded inserts, and collapsible core. Side action cams will only allow for external threads. Threaded inserts can produce accurate internal and external threads, but the long cycle time will increase part cost. A collapsible core can quickly produce internal threads, which will be used in this mold.

Undercut designs are often used to create threaded parts, such as screw-on bottle caps, snap-on products such as lipstick containers, and a variety of consumer, medical, automotive, and other products. Threaded caps illustrate well the complexities associated with undercuts. After the cap is formed, the threads of the part and the threads of the core are intermeshed and must be disengaged before the core can be pulled out and the cap removed from the mold.
