For the past 4 decades, we have perfected a line of clamshell style heat transfer press equipment that meets the business and manufacturing needs of customers worldwide. The Digital Knight clamshell heat presses feature a state-of-the-art control system and heavy-duty solid steel welded framework. These machines boasts a lifetime warranty on the heat platen, and an unprecedented 3-year warranty on the heat-control electronics. The heat platens use SuperCoil-Microwinding™ heater technology, a system of embedded heater windings that wind tightly and closely together throughout the entire platen for extremely even heat, fast recovery & fast heat up times. The DK20 and DK16 clamshell presses also feature an AUTO-RELEASE upgrade. This inexpensive feature makes these presses semi-automatic "Pop-Up" machines. Without an air compressor, the presses open automatically at the end of the timing cycle for added productivity and ease of use. Check out the DK20-AUTO and DK16-AUTO add-on upgrades for the DK20 & DK16 clamshell presses! Our clamshell presses open much wider and lift up far away from the rear of the pad, staying away from user hands. The extra long & wide handle and smooth gas shock lift make for the easiest and safest clamshells to operate on the market!
