For those seeking large quantities or custom specifications, buying directly from an OEM/ODM manufacturer like KingStar is an excellent option. As an experienced manufacturer in the stainless steel drinkware industry, we specializes in producing high-quality sublimation-ready tumblers. These tumblers are made from premium materials such as 18/8 stainless steel and come pre-coated with a polymer layer designed to bond with sublimation ink, ensuring long-lasting, vibrant prints.

By purchasing directly from manufacturers, businesses and brands can access wholesale pricing and customization services. At KingStar, for example, we offer a wide range of customization options, including various sizes, shapes, handle types, lids, and finishes to meet specific project requirements. Additionally, we provide Pantone color matching and branding options like laser engraving or screen printing, which allow for further personalization beyond sublimation.

Advantages of Buying from OEM/ODM Manufacturers:

• Customization: Full control over design, size, shape, and branding.
• Bulk Pricing: Cost-effective for larger orders.
• High-Quality Materials: Premium-grade stainless steel and coatings for optimal sublimation results.
• Certifications: Our products meet international standards (FDA, LFGB, etc.), ensuring safety and durability.

Sublimation printing transfers vibrant, full-color designs onto a specially coated tumbler using heat and pressure, resulting in durable, high-quality images that won’t fade.

1. Create Your Design

Sublimation works best with high-resolution, digital images, so ensure that your artwork is at least 300 DPI (dots per inch) for crisp and vibrant results. You can design your image using software like Adobe Illustrator, Photoshop, or CorelDRAW. Pay close attention to the dimensions of your tumbler, as you’ll need to adjust your design to wrap around it perfectly without distortions.

2. Printing the Design with Sublimation Ink

Sublimation printers, such as those from Sawgrass or Epson, are specifically designed to handle sublimation ink. Standard inkjet or laser printers won’t work for sublimation because the ink must be specially formulated to transfer under heat. Make sure to use sublimation paper for printing, which is designed to hold and release the ink onto the tumbler during the transfer process.

3. Cut and Prepare the Transfer

After printing your design, trim the excess sublimation paper to ensure it fits the tumbler perfectly. Wrap the printed sublimation paper tightly around the tumbler, with the design facing inward. To keep the paper securely in place, use heat-resistant tape to prevent movement during pressing. Ensure the tape doesn’t cover any important parts of the design. Additionally, to protect your tumbler from unwanted ink residue or damage, wrap the entire tumbler in protective shrink wrap or a silicone sleeve. This will hold the transfer paper snugly against the tumbler and help create even pressure during the heating process.

4. Use a Heat Press or Oven

There are two primary methods for sublimating tumblers.

• Tumbler Heat Press: This machine is specifically designed for cylindrical items like tumblers. Set the press to the recommended temperature (typically 350°F to 400°F or 175°C to 205°C) and apply pressure for around 60 to 90 seconds.
• Convection Oven: If using an oven, preheat it to around 375°F (190°C). Place the wrapped tumbler inside the oven for 6 to 8 minutes, rotating it halfway through to ensure even heating. For this method, you’ll need sublimation shrink wraps or silicone wraps to maintain pressure during the process.

5. Cooling and Unwrapping

Once the heating process is complete, carefully remove the tumbler using heat-resistant gloves. The tumbler will be extremely hot, so handle it with care. Allow it to cool for a few minutes before peeling off the shrink wrap or silicone sleeve, along with the sublimation paper.

Manufacturing an insulated tumbler is a highly technical, multi-step process that involves precision engineering, high-quality materials, and advanced production techniques to ensure the final product delivers superior thermal retention, durability, and aesthetic appeal.

1. Material Selection

The manufacturing journey begins with the selection of premium-grade 304 stainless steel (also known as 18/8 stainless steel). This type of steel is favored due to its excellent resistance to rust and corrosion, its food-safe properties, and its durability under various environmental conditions. The steel is typically used for both the inner and outer layers of the tumbler.

2. Sheet Metal Forming

Once the raw materials are selected, the next step involves sheet metal forming. Large sheets of stainless steel are cut into the appropriate size and then molded into cylindrical shapes using hydraulic presses.

3. Vacuum Insulation Technology

After forming the inner and outer walls of the tumbler, these two stainless steel layers are welded together at the top rim. Using highly specialized machinery, a vacuum is created between the walls by evacuating all air. This vacuum acts as a barrier, significantly reducing the transfer of heat through conduction and convection. As a result, hot beverages stay hot and cold beverages remain cold for extended periods.

4. Surface Finishing and Treatment

Once the vacuum insulation and welding are complete, the tumbler undergoes a series of surface treatments. Polishing is done to smooth out any rough edges and improve the overall appearance of the tumbler. Some tumblers may receive an additional surface coating, such as powder coating or electroplating, depending on the desired aesthetic and functional properties.

5. Lid and Gasket Manufacturing

KingStar’s most tumblers feature a lid made from BPA-free plastic, designed for durability and ease of use. The lid may also incorporate silicone gaskets to create an airtight seal, preventing leaks and ensuring maximum temperature retention.

6. Assembly and Quality Testing

Before the tumbler is shipped out, it undergoes final assembly. The lid is fitted, and any additional components, such as silicone bases or handles, are attached. Once assembled, the tumbler goes through rigorous quality control tests. This includes testing the insulation performance (how long it can keep beverages hot or cold), leak-proof properties, and overall durability.
