Heat Transfer Introduction
In this section, we will attempt to help you better understand and operate your HIX Heat Transfer equipment. We have assembled many of the questions we have received with the intention of helping to guide, troubleshoot, and solve your problems.

There are three things that affect the success of heat-applied transfers. Every heat press must be able to control TIME, TEMPERATURE, and PRESSURE.

Time – Time can be controlled by a simple bell or egg timer, or an audible beeper or alarm timers. Time can also be regulated by an automatic opening feature, where the press opens automatically at the end of a preset time, such as our N-880, N-680, S-450, S-650 models.

Temperature – Reliable temperature is a key issue in most transfer application failures. When a 350° readout is really only 320°F, a transfer requiring 350° for application won’t work. A warped heat casting (even slightly) can lead to unevenly applied heat and the transfer won’t adhere to the substrate. Some manufacturers (not Hix) produce heat presses that use two elements in their heat platen. If the tolerances are ±3%; at 400°F – 3% = 12° and 400° + 3% = 12°, that is a total of 24°. Their heat platen temperatures can vary side to side and cause transfer failure. If you have a 5 second transfer, the press works, but heat recovery time is usually 15 seconds. If you are cycling faster, the press will not recover to full heat and you will begin to have transfer failure. With the N-880 model, we do offer a hotter heat head with more amperage in its 16”x20” size. This is a special order item.

Pressure – Even and consistent pressure for the entire time is critical for good transfer application. Poor alignment of the heat head with lower platen, warped castings, and pad buildup or void (air pocket or trouble in pad) all contribute to pressure failures.
