Meet Procolored Brand New Technology - Siphon White Ink Circulation

The squeezing(peristaltic) circulation system utilizes multiple rollers to alternately squeeze and release the flexible ink tube, causing the volume of the tube to periodically decrease and restore, thus generating the flow of white ink. Over time, this continuous operation will accelerate the aging process and the tube will gradually lose elasticity, eventually leading to a decline in sealing performance or even damage and leakage of the tube.

For professional users of DTF printer, this is not a significant issue. They will regularly maintain the tube system and they can promptly repair the pipeline if there is any damage occurring. However, among our clients, there are some that are new to the DTF printing technique. Occasionally, we receive complaints from them stating that there has been a sudden issue with the white ink supply of the printer and the worst part is they don’t know what to do at all.

They might be successful in their own businesses, but get quite panic and helpless when facing a white ink issue. This mechanical failure of the circulation system put them into significant challenges and troubles. That’s totally understandable and reasonable, since sometimes white ink issue can be quite complex and need professional techniques based on abundant experiences.

Below example might help you be more in their shoes:

Picture that you have received numerous orders, and suddenly, without any warning signs, the white ink supply in your printer breaks down. You are uncertain about when the tubing might be repaired, and you feel anxious about having not fulfilled the orders. At such a juncture, you would hope for a new circulation system that can provide a more stable ink supply and requires minimal maintenance. Most importantly, it should come with the crucial feature of built-in contingency support.

Procolored understands all the concerns and helplessness, and we decided that a workable and significant technology improvement must be implemented. After extensive researches and developments, our technical team has innovatively introduced a new circulation system on DTF printing machines and that is, Procolored Siphon White Ink Circulation !

First of all, let’s figure out how Procolored Siphon White Ink Circulation works:

The electric motor, through a speed reducer, converts the high-speed rotation into low-speed and high-torque motion. This motion drives the diaphragm to move back and forth and generate positive and negative pressure, transporting the white ink from the intake end to the discharge end of the circulation system. The white ink flow is controlled by the opening and closing of the check valves to circulates within the system in a positive displacement manner.

When the diaphragm moves outward, the volume of the ink chamber within the circulation system increases, creating negative pressure. This causes the check valves to close at the discharge end and open at the intake end, drawing the white ink from the ink reservoir into the ink chamber of the circulation system.

When the diaphragm moves inward, the volume of the ink chamber decreases, creating positive pressure. This forces the check valves to close at the intake end and open at the discharge end, allowing the white ink to be discharged through the outlet pipeline and returned to the ink reservoir.

Meanwhile, at the discharge end of the circulation system, the white ink is transported to the print head utilizing the siphon effect.

So with help of the organic combination of check valves and the siphon effect, how does Siphon White Ink Circulation benefit a DTF printer:

A product being sold is not our ultimate ambition, a product being sold and got satisfactory feedback is what we keep fighting for.

This new system of white ink circulation is one practice of our promised missions. We hope it can to some extent improve the white ink stability and thus provide continuously perfect printing quality for all the current and potential users.
