Hotronix Auto Open Clam Heat Press – Magnetic Auto Release Heat Press for HTV & DTF

Patented Magnetic Auto-Open

The press opens by itself the instant the timer ends — no air compressor — preventing over-application and scorching while you load the next job or run a second press.

Magnetic-Assist Lockdown

Locks down easily with a patented magnetic assist that generates maximum pressure with less effort, reducing fatigue on wrists and shoulders over a long shift.

Over-the-Center Pressure

Delivers even, edge-to-edge heat and pressure regardless of substrate thickness — consistent results from job to job.

No Cold Spots

A cast-in tubular heating element every 2″ and a Platinum RTD sensor keep the platen evenly heated with accurate temperature control.

Three Sizes, Quick-Change Platens

Available in 11″×15″, 16″×16″ and 16″×20″, and compatible with optional Stahls’ Quick-Change platens for bags, sleeves, pockets and more.

Twin Timer™

Pre-set two independent time settings for two-step application or for pre-heat and application — handy for layered HTV and specialty transfers.

Apparel & Flat Goods

Tees, totes, bags and flat textiles with HTV, DTF, sublimation and screen-print transfers.

Hands-Free Multitasking

Auto-open lets one operator run two presses or prep the next job while this one finishes.

Specialty Substrates

With optional Quick-Change platens, press coasters, cutting boards, sleeves, pockets and more.
