A tumbler is a cup that is used mainly for drinking. It has straight sides and usually a flat bottom. A tumbler can be constructed of many different materials including plastic, metal, and glass. Typically, a metal tumbler is used to hold hot and cold beverages. We’re going to focus on stainless steel tumblers.
Design: A modern tumbler will usually have straight sides and flat bottoms. This design allows them to sit upright and not tip over easily.
Material: The material affects the insulation. Stainless steel tumblers are great for keeping things cold or hot.
Functionality: Stainless steel tumblers hold all kinds of liquid including water, tea (sweet and unsweetened), frozen drinks, smoothies, cold cocktails, and everything in between. Many have lids and straws to make it easy to keep yourself hydrated all the time.
People like stainless steel tumblers because of their unique design. Stainless steel tumblers have great advantages over the other types of tumblers from a temperature retention, durability, hygiene, environmental, versatility and fashion standpoint.
Stainless steel tumblers keep your beverages warm. Tumblers keep your drink warm for hours with the double-vacuum insulation.
Tumblers are normally made with 304 stainless steel that does not rust or oxidize. Stainless steel tumblers are tough. They resist breaking when you drop them. Many fit in your car cup holder.
Using a reusable stainless steel tumbler cuts down significantly on the use of plastic cups. Many stainless steel tumblers are recyclable when they reach the end of their useful life.
The manufacturing process used to make a stainless steel tumbler consists of several detailed steps, including shaping, welding, and finishing the tumbler to create a durable, high-quality product. Here are the main steps:
Material Selection: High-quality stainless steel like 304 or 316 is selected. These types of steel have been approved for use in contact with food and are resistant to corrosion and fading.
Quality Inspection: Stainless steel coils or sheets are inspected to ensure they meet product specifications and that they’re free of defects.
Sheet Cutting: Stainless steel is cut into the right sizes for the body and components of the tumbler using laser cutters or metal cutters.
Dimension Specifications: The sizes are based on the specific tumbler size (e.g., 300ml, 500ml, 750ml).
Deep Drawing: The cut pieces of stainless steel go through deep drawing processes. They’re stretched and drawn into cylindrical cup shapes.
Stamping and Shaping: Stamping may include processes such as water swelling, hydraulic shaping, or hydroforming. These processes form the tumbler into its final shape.
Trimming: Any excess metal is trimmed away to create smooth, uniform edges around the top. The pieces are also cut to a uniform height to prepare them for assembly.
Bottom Welding: The bottom piece is laser welded or TIG welded onto the tumbler body to create the bottom of the tumbler. A getter is sometimes used to improve the vacuum insulation.
Join the Inner to the Outer: Join the inner tank and the outer shell and join them together using a welding process.
Vacuum Sealing: We use specialized vacuum-sealing equipment to remove air from between the double walls. This is important for creating a stainless steel tumbler.
Process Duration: The vacuum sealing process itself can take several hours, but it is a crucial step to retaining the temperature of the drinks inside the tumbler.
Copper Plating: In some of the higher-end tumblers, we will sometimes copper plate the inside of the tumbler. Copper is a great material for conducting heat, so can use it to add insulative value to beverage holders because it reflects the heat back into the liquid.
Electrolysis Cleaning: The inside surface goes through electrolysis to remove any impurities or contaminants that might reduce the drink container’s ability to prevent corrosion.
Polishing: The inside and outside surfaces receive a polish to give each a smooth surface. The process creates either a mirror-like finish or a brushed surface for a dull matte finish.
Quality Inspections: Numerous quality inspections occur here to confirm that the surface is smooth and that there is nothing wrong with it.

Bulk Packaging: We put the finished tumblers into a case with special foam or other protective material to protect the tumblers and get them to you safely.
Deep-Drawing Machine: This draws the body of the tumbler.
Laser Welding Machine: Laser welding puts the top and bottom parts onto the tumbler.
Vacuum-Sealing Equipment: To create a vacuum between the double walls.
Electrolysis Equipment: Used to wash these out and to make them more corrosion-resistant.
Laser Engraving Equipment: Used to apply your branding.
These processes help ensure that stainless steel cups are convenient, durable, and beautiful. That’s why they have become a sought-after item in the marketplace and with our partners.
Customizing stainless steel tumblers helps you create products that fit your specific needs. It is a great way to improve profitability by serving your customers. Here are ideas related to customizing stainless steel tumblers.
Silkscreen Printing: You can add your logo to the tumbler body or cap using silkscreen printing. This process supports single-color and multi-color designs.
Laser Engraving: Use a laser to engrave your logo permanently into the tumbler’s stainless steel surface. This creates a high-end durable logo and is often used on high-end products.
Heat Transfer Printing: Use heat transfer technology to add high-quality patterns with rich colors. Use this method for complex patterns, logos, or text you want to put on the tumbler.
Embossed/Debossed Logo: Create an embossed or debossed logo to add a 3D effect to the product.
Custom Colors: Various color options can be provided depending on the brand guidelines or the market trends you’re following. Different finishes can be produced in matte, glossy or metallic. These colors are created through painting, powder coating or electroplating.
Gradient and Multi-color Designs: Besides basic colors, use a gradient or multi-color design to enhance the look and make the product stand out.
Printed Pattern: You can put printed patterns over the entire stainless steel tumbler. These printed patterns can be brand logos, designs, or whatever patterns you want to appear on the finished product. Use UV printing, heat transfer, or other processes to add colorful graphics.

Various Insulation Durations: You can customize different insulation quality tumblers depending on your requirements. Use the better quality tumblers to keep products warm for up to 12 hours. You can also customize medium-term insulation performance tumblers. These will keep products warm for up to 6 hours.
To ensure stainless steel tumblers have adequate insulation, follow specific steps related to design, material selection, manufacturing processes, quality control, and testing. Here are the steps and precautions We take to ensure optimal insulation:
Double-Wall Construction: Use double-wall construction, meaning two layers of stainless steel with a space between the layers of stainless steel.
Vacuum Sealing: Remove the air between the two walls, which creates a vacuum and minimizes heat transfer via convection and conduction.
Seamless: Make sure there is a seamless connection between the inner tank and the outer shell of your non-tumbler.
Food-Grade: Use 304 or 316 food-grade stainless steel for both the inner and outer walls. These types of stainless steel maintain excellent thermodynamics due to low thermal conductivity and don’t corrode.
Getter materials: Use getter materials (activated charcoal, special alloys, etc.) inside the vacuum while it’s being sealed. These materials absorb leftover molecules and help maintain the vacuum over time.
Insulating Components: Use high-quality, heat-resistant silicone or rubber for your seals and gaskets.
Advanced Welding Techniques: Use laser welding or TIG welding to join the parts to ensure that no air is penetrating the welding joints to the vacuum space.
Vacuum Technology: Use vacuum equipment to achieve the required level of vacuum which is a high vacuum (typically 1×10⁻⁴ Pa).
Temperature Control: Control the temperature so that you don’t overheat material during the production process and affect the shape of the material you are using for insulation.
Vacuum Integrity Testing: Use helium leak detection or vacuum decay testing to ensure the vacuum space is properly sealed and maintained.
Thermal Performance Testing: Test the ability of the tumbler to retard heat loss using standardized test methods. such as:
Material Checking: Use X-ray fluorescence (XRF) analyzers to verify the stainless steel composition.
Food Safety Certification: Rest assured, all of our products are 100% certified for food contact standards by the FDA, LFGB or EU.
Quality Management System: Our factory is ISO 9001 certified to ensure consistent quality manufacturing.
Environmental standards: Our factory complies with RoHS and REACH regulations to avoid using hazardous substances.
Use Third-Party Testing: Use a third-party lab, such as SGS or Intertek, to confirm the performance of the tumbler insulation.
Batch Testing: Regular testing on insulation materials, maybe one for each batch produced.
Certification Marks: Use the appropriate certification marks on the tumbler to show your product meets these various standards.
Lid Insulation: Use an insulated lid to ensure a tight seal so that heat does not escape from the top.
Exterior coating: Add a powder coat, or some other form of finish on the outside to prevent heat escaping.
Available Skilled Personnel: We regularly train employees to learn the specialized manufacturing knowledge and quality control processes required for various types of insulated products.
Standard Operating Procedures: We develop and implement SOPs for each step of production.
Customer Feedback: We get feedback from our customers and evaluate our products based on insulation performance to make improvements in specific areas.
R&D: Conduct research and development into additional materials and technologies you can use for improved insulation.
To help our stainless steel tumbler work in as many automotive cup holders as possible, our engineers created some clever designs and features. Here’s a quick rundown:
Narrow or Tapered Base: Many are designed with a narrower base than the wide top. They’re made to fit in standard-size car cup holders that are usually two-and-a-half to three-and-a-half inches in diameter.
Anti-Slip Materials: Materials such as rubber grips and silicone on the bottom of the cup prevent the tumbler from sliding. They create extra friction between the surface of the tumbler and the inside of the cup holder.
Weighted Bottom: The idea of having a low center of gravity is an effective solution to prevent the cup from tipping over when there’s sudden motion or vibration in your car.
Cup Holder Adapters: The adapters increase the application of larger-size tumblers. They fit down into your cupholder and give the larger cup a snug home. Many include anti-vibration design and rubber fringes to secure the tumbler and prevent it from falling over or wobbling.
Adjustable Cup Holders: Some vehicles have cup holders that adjust to the size of the cup. The sides move in and out and snug the tumbler down to hold it in place.
Grip Coating: Most tumblers have rubber coating or texture on the outside. This makes them easy to grab and remove from the holder. It also ensures they stay put and don’t slide out of position.
Spill-Proof Lids: The tumblers with leak-proof lids (e.g., push button or flip top) that won’t spill even if the tumbler tips slightly. Sealed gaskets fit inside the lip of the lid to help prevent leaks when the tumbler is moving around.
Proper Height: Our designers design the car cup holder to be the appropriate height based on the depth of the car cup holder. If it is too tall, it tends to be wobbly and fall over. If it is too short, then it tends to come out of the cup holder.
Balanced Design: A tumbler that’s balanced concerning height, weight and width leads to better stability, especially in a moving vehicle. All of this is for our designers to consider!
Vibration and Tilt Test: Our engineers will test the stability usually by shaking the cup to simulate vibrations inside of your car and then tilting the cup to make sure that it stays put no matter how you’re driving.
Compatibility Testing: We make sure it works in cars. We test these cups with different cars and car cup holders to ensure that they fit and stay put.
We’ll take feedback from you and other users to find out about it. We are making iterative design improvements based on actual use.
By combining these design features with adaptive solutions like cup holder adapters, we can ensure the stainless steel tumblers will work well in different car models to be a stable, non-spilling, convenient solution while driving around.
