Curious how Yeti tumblers are built to last? Discover the step-by-step process that turns steel into premium drinkware.

Yeti tumblers are made from high-grade stainless steel using advanced forming, vacuum sealing, and finishing processes to ensure durability and performance.

Keep reading to understand what sets Yeti apart in the world of insulated drinkware.

What Materials Are Used to Make Yeti Tumblers?

Yeti tumblers are made from 18/8 stainless steel¹, known for its high corrosion resistance and food-safe properties.

Yeti uses food-grade 18/8 stainless steel for strength, safety, and long-lasting durability.

Material Benefits

• Resistant to rust and corrosion
• Doesn’t retain flavors or odors
• Suitable for hot and cold beverages

How Are the Outer and Inner Walls Formed?

Laser-cut stainless steel sheets are shaped using deep drawing and stretch forming techniques.

The inner wall is deep-drawn for a seamless interior², while the outer wall is stretch-formed for durability.

Wall Forming Techniques

• Deep Drawing: Pulls steel into shape with minimal seams
• Stretch Forming: Shapes outer shell for structural strength

What Is the Vacuum Insulation Process in Yeti Tumblers?

Once assembled, the space between the inner and outer walls is vacuum sealed using high-temperature batch processing.

Yeti uses no-pipe vacuum technology³ to remove air and create long-lasting insulation.

Key Vacuum Steps

• Place units in vacuum oven
• Heat and remove air between walls
• Weld mouth and base to seal vacuum

How Are the Tumblers Assembled and Sealed?

Inner and outer walls are precisely aligned and welded at both the mouth and bottom⁴ to maintain vacuum integrity.

Welding locks the structure and ensures insulation is airtight and durable.

Assembly Steps

1. Fit inner into outer shell
2. Add getter to absorb residual gases
3. Weld top and bottom closures

What Finishing Techniques Are Used on Yeti Tumblers?

Each tumbler undergoes powder coating or laser engraving⁵ to enhance grip and customize branding.

Powder coating creates a tough, non-slip surface; laser engraving adds fine detail.

Surface Finishing Options

• Powder Coating: Durable, colorful, and textured
• Silk Screening: Ideal for logos and simple designs
• Laser Engraving: Precise, permanent branding

How Are Yeti Tumbler Lids Made and Assembled?

Lids are molded from BPA-free plastics and assembled with silicone gaskets⁶ for a tight, leak-proof fit.

Injection-molded lids with silicone seals provide durability and splash resistance.

Lid Features

• BPA-free, clear plastic
• Magnetic slider or press-fit options
• Silicone gaskets for seal integrity

What Quality Control Measures Ensure Yeti’s Durability and Performance?

Every tumbler is subjected to visual inspection, vacuum integrity checks, and leak testing⁷.

Rigorous testing ensures that each Yeti product meets the brand’s high performance standards.

QC Checklist

• Visual Inspection: Coating and welding flaws
• Leak Testing: Confirm no seal failures
• Vacuum Test: Check insulation efficiency

Conclusion

Yeti tumblers are crafted from premium stainless steel using precision forming, vacuum insulation, and tough coatings for lasting quality.

FAQs

Are Yeti tumblers copper lined?
Most Yeti tumblers do not feature copper linings. Standard models rely on vacuum insulation for temperature control.

Where are Yeti tumblers manufactured?
They are primarily manufactured in China and the Philippines using advanced stainless steel processing facilities.

Can the powder coating chip or peel?
Yeti's powder coating is highly durable, but excessive impact or abrasion may cause wear over time.

What makes Yeti different from cheaper tumblers?
Yeti's tumblers feature precision welding, vacuum sealing, and strict quality control that ensure consistent insulation and durability.

Is Yeti dishwasher safe?
Yes, Yeti tumblers and lids are generally top-rack dishwasher safe, though handwashing extends the lifespan of the coating.
