Manufacturing Equipment Fabrication: Cell for Widemouth, Tamper-Evident Plastic Closure A client in the plastics industry presented us with a challenge: Create a product whose requirements were beyond any currently available process. The project called for production of manufacturing equipment for a 70 mm wide-mouth tamper-evident plastic closure that would run at 900 cpm. To fulfill this project, we would need the new process to run at double the speed of what was available at the time. We worked with and invented several new patented processes and mechanisms and built the manufacturing cell that would compression mold a wide-mouth shell at 900 cpm, slit and line at 1000 cpm, inspect, and package the caps for shipment.
Re-engineering the process through prototype development and testing, we met all of our customer's specifications. The process cycle time went from 18 seconds to 3.8 seconds. JB Tool & Die has the experience and the resources to manufacture solutions. To learn more about this manufacturing cell fabrication project, please see the table below or call us directly.

|
| | Project Description | - Customer presented goal to produce a large diameter closure (70mm)
- At time of project start, closest available methodology capable of 400 cpm on 63mm platform
- To be able to justify the project and be successful, the new process would need to run at over double the current speed
- Several new processes & mechanisms required invention (14 patent applications with 7 awarded)
- Through prototype development and testing, a 3.8 second cycle time was achieved over existing process capability of an 18 second cycle time
