Pure Titanium Liner + Vacuum Structure
Positioned in the high-end outdoor drinkware market and launched for North America, the EU and Japan & South Korea outdoor and lightweight camping markets, this tumbler addresses the triple demands of high-end outdoor users for lightweight build, insulation and health safety. The food-grade pure titanium inner liner retains the lightweight, corrosion-resistant properties of titanium, paired with a tailless double-wall vacuum structure that blocks heat conduction. Insulation lasts 6 to 12 hours, solving the weak thermal performance of traditional pure titanium cups.

Corrosion Resistance & Coating Benefit

The pure titanium liner resists corrosion from all common beverage types, including acidic drinks and tannin-heavy teas that can damage lower-grade metal liners. It is paired with a MARSCOAT easy-clean coating that simplifies removal of coffee and tea residue, with exact coating specifications and coverage adjustable per project requirements. The inert titanium material does not react with drinks or release metallic flavors, preserving full original beverage taste.
Lightweight Premium Build
Pure titanium's low density gives this tumbler a lower weight than equivalent-capacity stainless steel vacuum models. It reduces carrying strain during all-day outdoor use for a better overall travel experience. The outer shell uses stainless steel to balance structural strength and cost, positioning the tumbler as a premium outdoor luxury option for quality-focused buyers.
Custom Development & Compliance
Dongke Electric Heating offers deep OEM and ODM customization, with adjustable product details, custom exterior designs and bespoke packaging to match brand positioning, plus support for dedicated high-end titanium drinkware development. The factory uses green production processes, with zero VOC emissions from inorganic coating application, meeting global environmental regulatory requirements.
