What’s the first thing you think of when you hear the words heat press? For most, the first thought is an iron and ironing board, or maybe a factory churning out thousands of t-shirts. And, I suspect if I said clamshell heat press, the first thing that would come to mind would be seafood.
However, in this case, I’m talking about heat presses — the ones used by small businesses, hobbyists, and crafters. Thanks to the crafting renaissance and the internet a need for smaller and affordable heat presses surfaced.
And in typical entrepreneurial fashion, when there’s a need, it must be met. So, today there’s a diversity of smaller and affordable heat presses available to everyone.
So What Is a Heat Press?
A heat press is a machine designed to use heat and pressure to transfer an image to a substrate. It is also called a heat transfer machine.
It typically has two independent surfaces or platens. The top platen is most often made of aluminum embedded with heating elements. The bottom platen, most often covered with a silicone gel mat, is where you place the substrate.
You place a substrate on the bottom platen, place the transfer on top of the substrate, and then press the top platen down. That sandwiches the substrate and transfer between the upper and lower platens.

The pressure and heat from the upper platen moves the image from the transfer to the substrate. A heat press by design gets hotter than an iron, or laminator, and that higher temperature allows for a more professional result.
Heat presses allow you to transfer your individual and unique artwork, or designs, onto t-shirts, hats, wood, metals, paper memo cubes, jigsaw puzzles, tote bags, mousepads, ceramic tiles, mugs and plates, and many other materials.
There are three different types of heat presses available for small businesses and crafters alike. Presses that don’t require 220-volt outlets or any high amperage circuits.
Affordable and small enough to put on a table, plug it in, and start pressing. But first, you’ll have to decide which type of heat press will work best for you.
A clamshell heat press has a hinge between the top and bottom platens and is an upward-opening machine. With its clam-like open and close movement, it’s easy to understand how this heat press got its name.
Of the three different types of heat presses, the clamshell heat press takes the least amount of counter or desk space. And, thanks to its design is perfect when you need something portable, for conventions or on-the-go heat press work.
The clamshell heat press is a one or two-step operation (depending on the press). You close the press down, and when it’s finished, you open the press. It’s simple, effective, and efficient, making it the perfect starter heat press for a beginner or the occasional user.
While the clamshell heat press is good for imprinting t-shirts, canvas bags, caps, and other materials, it is limited when it comes to material thickness. Depending on the model, you will be limited to materials no thicker than one-half to three-fourths of an inch thick.

Another concern with the clamshell heat press is their “pinch effect.” Because of its clam-style design, when the press is locked down, it pinches thicker substrates or locks down unevenly by hitting in the back first.
Some major manufacturers have corrected this issue by developing presses with an over the center pressure adjustment as well as a floating top platen that levels off before pressing the substrate.
But the biggest downside of a clamshell heat press is that your hands work directly under the heat source. The top platen of most clamshell heat presses does not open more than 70 degrees, making it easy to burn your hands.
The swing away heat press, when closed resembles the clamshell heat press. But rather than opening like the clamshell heat press, the top raises and then rotates to the side.
The swing away heat press requires more workspace than a clamshell heat press. It’s not a press you can place next to the wall as the top plate rotates up to 360 degrees. And because of the swing mechanism, they can feel less sturdy.
But the swing away heat press is good for thicker materials. The top platen moves up and down horizontally. So the heating element comes down evenly and flat against the substrate.
A big advantage to using the swing away heat press is the safety of loading and unloading materials. Your hands are not working under the heat source as they are with the clamshell heat press.
The downsides are space requirements, more moving parts that could wear out quicker, and it’s heavier, so it lacks portability.
The draw heat press has a lower platen that pulls out towards the operator. Similar to opening a drawer. The upper platen raises and lowers like the swing away heat press, but does not rotate.
Because, like the swing away heat press, the heated upper plate has a level horizontal movement, it is a good choice for thicker materials.
The upper platen on most draw heat presses does not rotate, and therefore it does not require the amount of space a swing away heat press does. But it does require more space than a clamshell heat press because you will need room for the lower platen to pull out.
Another, possibly the biggest advantage to the draw heat press is you are not working under the heat source.
The downsides of the draw heat presses are they are more expensive, more moving parts that could wear out quicker, and it’s heavier, so it’s not portable.

Wrapping It Up
We’ve talked about and defined clamshell, swing away, and draw heat presses. Hopefully, when someone now says clamshell heat press, your first thought won’t be seafood.
Creating beautiful imprints has never been so easy thanks to these modern heat press machines. Show off your creativity with one of a kind t-shirts, tote bags, or hats.
Give unique, one of a kind gifts to family and friends. Or design and make those reunion t-shirts for your family. Not to mention making special “take home” gifts for weddings or birthday parties.
But before you decide which style of heat press will be the best one for you, think about how much available space you have and if you need portability in a heat press.
No matter which style you choose, you will want time and temperature digitally controlled. Too much or too little heat or time will ruin your project. Temperature consistency and control is the most important thing to look for in a heat press.
It’s important to remember that using an extension cord for heat transfer machines is not a good idea. If you must use an extension cord, make sure it is a heavy duty cord and as short as possible.
So pick the best clamshell heat press and get your creativity on. Make something fun!
