The Science Behind A Rotary Heat Press Calender

We will want to consider a rotary heat press calender which can offer much faster production speeds when our sublimation printing operation is geared more towards high volume printing of textiles, sports- and fashionwear, or we wish to print long lengths of the substrate (for example, banners and flags).  And today’s blog will introduce the science behind the industrial heat press machine.

Rotary press machines have a cylindrical felt covered drum, which is filled with oil. The oil is heated to the required temperature (200°C) creating an even and stable heat across the entire width of the drum. For roll-to-roll printing, rolls of the substrate and printed transfer paper are transported together around the heated drum, remaining in contact with the drum for a given length of time. A roller is used to apply tension to the tubular felt, which in turn applies pressure to the substrate and paper, holding it against the heated drum to facilitate the sublimation process. Separate rollers may also transport ‘protection paper’, which is used to prevent any excess gas that doesn’t sublimate into the substrate from transferring to the felt on the drum, (which could lead to the unwanted transfer of the dye back onto the roll of the substrate).

How to Maintain a Rotary Heat Press Calender?

As we all known, the price of a rotary heat press calender always is expensive, which is a high grade heat transfer printing equipment that plays an important role in the process of sublimation printing, so we need to pay attention to maintain it correctly. Today’s article will share you how to maintain a calender. 🙂

1. Remember to keep your heat press clean, this is basic, and also important.

2. Check every part of the heat transfer machine regularly to make sure they can work normally.

3. Each time before you start operating, remember the machine must be refueling according to the rules.

5. Joint head: drops of butter (a week / time, 10-20g), oil (1-2 drops, 3 days / times).

6. Be careful when pressing the emergency stop button. Often use this button is harmful for the chain, towline and the belt.

7. Sometimes the optical axis will drop oil twice a week. The best method to avoid this situation is using the good quality media.
