ILLUSTRATIVE SOLUTION / NOT A COMPLETED INSTALLATION

Molded closures.
Assembled and ready to pack.

A proposed route for flip-top caps and multi-part closures that need handling, assembly or checks after molding. Different closure designs need different stations; a liner or leak test is not automatically part of every cap.

Closure design review drawings from the project archive

A procurement brief this could answer

“Our caps need closing, inspection and counted packing after molding. Some versions also have a liner. Can you propose a process that handles product changes without mixing parts?”

Proposed process

Orient cap → Insert liner if required → Close or assemble → Inspect → Separate rejects → Count → Bag or box

Evaluate feeding and nests around the cosmetic surfaces, hinge and sealing features. Where a liner is required, define orientation and seating checks. Where the cap is molded open, assess the first-closing movement using real molded samples.

A sealing or leak check requires an agreed mating interface and test method. Inspection of a closed cap alone is not evidence of leak performance. Packaging selection should prevent reopening, deformation or mixing in transit.

What must be demonstrated

Correct assembly, liner presence where applicable, closing function, cosmetic protection, rejected-part separation and pack counts. Agree the sample size, test conditions and required evidence before accepting the process.

Information for evaluation

Cap and mating-container drawings, molded material, supplied orientation, liner details, opening and closing requirements, appearance limits, packing format, variants, present bottleneck and target output.

Practical first step: trial the closing or liner-fitting operation before adding automatic feeding and final packing.

The archive supports closure design and trial-tooling work. The automation sequence here is a new solution example, not an extension claimed to have been delivered on that historical project.
