Insulated Travel Tumbler with Straw

We use a spin thinning machine to shape the cup body. This process stretches the insulated travel mug with straw into a very thin wall. The wall thickness is about 0.4 mm. The cup becomes lighter, but the strength does not go down. Spin thinning is a one-step process. There is no weld seam on the body. The cup comes from one piece of material. This means the insulated travel tumbler with straw will never leak from the bottom. The mold is important for this process. Our molds use alloy steel with chrome plating. We repair the mold every 100,000 pieces.

Spin thinning lets us make the cup wall thin. For the same capacity, our insulated travel tumbler with straw is about 20 grams lighter than others. This matters for a travel cup. A lighter cup feels better in your bag all day. But we do not thin the bottom. The bottom must handle drops and wear. So we leave 0.6 mm of thickness there. We only thin the middle part of the body. We have done drop tests. From 1 meter high onto concrete, the bottom does not change shape. The body does not crack either. So this insulated travel tumbler with straw is both light and tough.

This insulated travel tumbler with straw keeps your drink hot for 6 hours above 50℃. The inner layer is SUS316 steel, which resists rust better than SUS304. The straw lid makes it easy to sip. You can also customize the body with paint or powder coat. Patterns are available in heat transfer, 3D, or water decal. The spin thinning process gives you a light cup without losing strength. Try this insulated travel tumbler with straw for your daily commute or outdoor trips.
