Internal threads are commonly found on plastic parts that screw together, such as bottle caps, drinkware lids and plastic hardware. Due to the delicate nature of threads, molding these parts requires a slightly different approach than your average plastic part. An unscrewing core must be incorporated in the tool in order to eject them from the mold without damaging the threads.
In the past, these parts needed to be manually unscrewed from the core by hand to avoid stripping the threads. The additional labor and time it took to do this added to the part price and lead time. While many injection molding shops still follow this practice, we knew there had to be a better way. So we found one.
The Engineering Resource Center can now mold your internally threaded parts in a tool that runs automatically. As a result, you'll receive your parts without error and faster than ever. Watch the video to see it in action!
At The ERC, we know that you can't always compromise your design - especially with precision parts. That's why our promise has always been "your design, no compromises." Reach out to us for a Rapid Quote to take advantage of this new offering for your internally threaded plastic parts.
