What Should We Pay Attention to When Using a Textile Heat Press Machine?

The textile heat press machine is a large machine which plays an essential role during the process of sublimation printing. Therefore, we need to pay attention to some factors that will affect the result of our products when we use it.

1. Temperature and time

In this process, the rotary heat press machine requires temperature control in the 180 ℃ ~ 230 ℃ range, and the time is about 10 ~30s, while paying attention to the reasonable allocation of temperature and time.

Sublimation transfer technology, the key material mainly by disperse dyes, connecting materials, solvents and a small number of additives. Dye sublimation ink should have good sublimation transferability and permeability. And reached a certain degree of fastness indicators, the molecular weight of 23O ~ 380, sublimation temperature of 180 ℃ ~ 240 ℃ commonly used transfer printing dye anthraquinone dyes, azo dyes, and cationic dyes and so on.

The pressure is also one of the important points when we use textile heat press machine. For example, if the pressure is too small, the gap between the fabric and the transfer paper is large, the yarn is round, the ink gas molecules collide with the air and escape, resulting in poor printing effect, while the ink is also easy But the pressure is appropriate, the yarn is flat and the transfer paper between the gap is appropriate, the transfer coloring effect is good, clear pattern, smooth lines Fine: If the pressure of calender heat press is too large, it is prone to deformation, fluff and heavy fabric morphological changes and other issues, resulting in rough and color rendering and other shortcomings. Therefore, the control of the transfer pressure on the printed pattern, clear pattern, visual effects and so very critical.

How to Choose a Industrial Heat Press Machine?

An industrial heat press machine (or simply “heat press”) is used to apply for large format fabrics. How do you pick the right rotary heat press?  Take your time and consider your goals, not just the price. And today’s article is to share how to choose the machine.

industrial heat press machineTwo key factors when choosing a rotary heat press machine are the diameter and the width of the drum. Drums can vary in diameter from 20 cm to 2 m+, and the wider the diameter of the drum, the higher the press’s production speed. This is because the substrate needs to be in contact with the heated drum for an average of 40 seconds to achieve effective sublimation. This means that it can pass twice as quickly over a 40 cm drum compared with a 20 cm drum due to the larger contact area.

There is also a wide range of drum widths available, from 400 mm (working width) to 5000 mm+. It makes sense to match the width of the drum to the width of your printer, or you could opt for a wider drum to future-proof your investment in the event that you move up to a wider printer at a later date.

Traditionally, industrial heat press machine runs much faster than the printers. However, things are beginning to change with more productive digital printers coming onto the market. Our company has a printer that can print at up 400 m square per hour, and we need a 1 m drum heat press to keep up with it.

Our company is a machine manufacturer with over 10 years of experience producing industrial rotary heat press. We take care of each customer’s idea and, if necessary, our team can make the special size of rotary heat press machine for the customer. Any question, please contact us. Thank you for your reading

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).
