ColorSub 3 in 1 40 OZ Tumbler Heat Press Machine 11 OZ

The ColorSub 3 in 1 Tumbler Heat Press Machine is a dedicated drinkware transfer unit designed for crafters and small shops making custom tumblers, mugs, glassware, and bottles. Powered by a 110V, 750W electrical element, it delivers controlled heat across a 0 to 400 F range and timing up to 999 seconds, solving the challenge of pressing uneven or large-capacity drinkware.

Versatility comes from the three included heating elements made from aluminum and silica gel. The 40 oz two-part split set includes a cylindrical heater (3.27 to 3.94 inch diameter, 6.69 inch length) and a conical heater (3.94 inch bottom diameter, 4.33 inch top diameter, 3.74 inch length) specifically tailored for tapered travel mugs. For standard drinkware, the 15 oz attachment handles cylindrical vessels measuring 2.83 to 3.54 inches in diameter and up to 5.31 inches long.

Operation is managed via a digital LCD screen that displays settings clearly and holds steady target temperatures. A built-in production counter helps monitor batch progress across repeat jobs. The package also includes essential setup gear, providing heat-resistant gloves and a roll of sublimation tape so you can secure transfer paper immediately.

Working with the press does require attention to a few operational traits. For full-wrap artwork, the seller advises rotating the tumbler 180 degrees and pressing a second time. Users must also avoid leaving heating attachments turned on without a tumbler inserted, as empty heating can deform the silicone pads over time. Additionally, placing a room-temperature blank inside the press causes a brief, normal drop in displayed heat.

Verdict: This 3-in-1 press is an excellent choice for crafters who frequently sublimate both standard mugs and oversized 40 oz tapered tumblers. It provides the exact attachments and digital precision needed to handle multi-sized drinkware projects at home.

• Make custom 40 oz tapered or straight tumblers that require dedicated split heaters.
• Need a digital counter to track multiple consecutive drinkware orders.
• Want an all-in-one bundle that includes heat gloves, sublimation tape, and multiple heating pads.

What drinkware sizes fit this heat press?
It fits 15 oz drinkware with diameters from 2.83 to 3.54 inches, as well as 40 oz cylindrical (3.27 to 3.94 inch diameter) and conical (3.94 to 4.33 inch diameter) tumblers.

How do you press a full-wrap design?
For full-wrap designs, press the tumbler once, rotate it 180 degrees inside the attachment, and heat press it a second time.

Why does the temperature drop after inserting a tumbler?
A temporary drop in temperature is normal when placing a cooler tumbler blank into the heated attachment.

Can I leave the machine running while empty?
No, heating the attachments for extended periods without a cup inserted can cause the silica gel pads to deform.
