Case Study: Tervis achieves rapid market launch and meets surging customer demand with Protolabs' quick-turn injection molding

Drinkware Maker Uses Digital Manufacturing to Quench Demand

Tervis, a U.S. maker of double-walled insulated tumblers, needed a covered wine glass to meet unexpected customer demand but faced a design challenge: repeated dishwasher cycles caused part shrinkage that made lids fit too tight or too loose. Tervis turned to Protolabs for rapid injection molding and design-for-manufacturability support to accelerate development.

Protolabs used its automated quoting/DFM analysis, applications-engineer guidance, and quick-turn injection molding to iterate the cover design (two runs) in food-safe, BPA-free polypropylene and produce low-volume end-use parts. The result was an immediate sellout at retail, with Protolabs shipping additional covers in 10 days—allowing Tervis to meet unanticipated demand and rapidly scale production.
