Hinge design
Living hinge rules in the design guide.
Hinge designPackaging
Packaging components for tight launches
Closures and thin features need fill balance, hinge design, and resin choice aligned to line speed.
Packaging
Packaging components for tight launches
Closures and thin features need fill balance, hinge design, and resin choice aligned to line speed.
Living hinges and tamper bands belong in the DFM review before tooling.
Thin walls near threads or seals need uniform thickness transitions.
Seasonal launches still use one production tool once the design is frozen.
Manufacturing
Quote with sector context on the model
Upload CAD so DFM and material assumptions match how the part is used.
- Note environment: UV, chemicals, or wear surfaces.
- Call out cosmetic faces versus functional mates.
- List expected annual volume even if it is a range.

FAQ
Buyer questions
Do you build high cavitation molds?
Cavity count follows program quotes. Upload CAD for specifics.
How do we reduce warp on thin lids?
Uniform wall and gate location are first checks in DFM.
