5 Popular Auto Open Heat Press Machines Reviews

by Jesse Luginbuhl // updated on: August 20, 2020

While shopping for a quality heat press for your printing business, you may come across machines equipped with auto-open functionality. If you’re not well acquainted with different types of heat press, you may not be aware of this unique feature. However, most of the professional printers and designers know that only the clamshell-style heat presses feature the auto-open system.

So what exactly is an auto-open heat press machine? How can you benefit from using a heat press that comes with this feature? Are what the drawbacks of the auto-open technique are, if any? Is a heat press integrated with this feature indispensable for your business, or can you manage with a manually operated machine?

We will try to answer these questions in this review on popular auto-open heat press machines in the best possible manner.

What exactly is an auto-open heat press?

An auto-open heat-press, as the name indicates, is a machine whose heat platen opens automatically when the timer goes off. This feature is available only in digital heat presses, and that too exclusively in clamshell-style heat press machines. When you set the time or the duration for which the heat transfer process will continue, the timer goes off after the expiry of the time interval.

And the moment the timer sounds the alarm, a heat press featuring auto-open functionality will open up on its own. A digital heat press machine tends to be quite expensive just because it comes equipped with the auto-open functionality.         

Differentiating between fully auto open and semi-auto heat presses

A fully automatic or automatic heat press opens when the timer goes off and closes when you press a knob. On the other hand, a semi-auto heat press opens up automatically with the beeping of the timer but has to be closed manually. Another significant advantage of using an automatic heat press is that it is also capable of programming the pressure level.

The fully automatic heat press adjusts and sets the pressure mechanically that is suitable for the substrate. So the machine programs the appropriate pressure level each time you place a different or new substrate (the material or fabric). Fully automatic heat presses happen to be way more costly than the semi-auto heat presses.

Automatic heat press machines are, by and large, designed and manufactured for large-scale commercial businesses or industrial units. You’ll need to invest separately for an air compressor to operate a fully automatic heat press.

Auto-opening feature is exclusive to clamshell-type heat presses

Talking about the different types of heat press machines, there are three distinct styles-swing-away, draw out, and clamshell heat presses. When it comes to equipping heat presses with the auto-open mechanism, only the clamshell type can accommodate the feature, thanks to its distinctive design. Clamshell heat presses tend to be relatively compact, compared to the swing-away or the pull-out style, and convenient to use.

Benefits and drawbacks of auto-open mechanism


  • Frees you from the worry of having to open and close the machine
  • You can focus on  how to complete your project quickly and effectively
  • Chances of heat transfer material getting overheated or scorched are minimal
  • You’ll have to make less effort to complete heat transfers in bulk


  • Auto open heat presses, especially the automatic ones are costly
  • Your investments would go down the drain if an extended warranty does not cover your machine
  • You’ll not have the option of choosing a swing-away or draw-out style machine
