DTF Printers in Digital Printing: An Unshakable Status
In the field of digital printing, the status of DTF printers is unassailable. As a reliable partner to the DTF printer, the powder shaker gains increasing importance, as it directly determines the durability of subsequent heat transfer patterns.
Working Principle of the Powder Shaker: Simple and Efficient
The working process of the powder shaker is not complicated, mainly including three steps: powder sprinkling, powder shaking, and drying. First, sprinkle hot melt powder evenly on the heat transfer pattern, then shake off the excess hot melt powder, and finally, dry the heat transfer pattern sprinkled with hot melt powder.
Analysis of Reasons Why Powder Can't Be Completely Shaken Off:
1. Ink Issues
If the white ink is too thin and has high moisture, it can easily cause ink bleeding (where the oil and water of the white ink seep beyond the edge of the pattern), leading to more hot melt powder sticking to the pattern's edge when shaking powder. If there are water stains around the printed pattern before powder sprinkling, it can be determined to be an ink issue. The solution is to change the ink or pre-dry before sprinkling.
2. Quality Issues of DTF Film
Under the same consumables and production environment, if the powder sticking issue improves after changing to another type of DTF film, then there is a high probability that the quality of the DTF film is poor or unqualified, or the compatibility between the DTF film and the ink is not good enough. The solution is to replace with the appropriate DTF film.
3. Hot Melt Powder Issues
If the hot melt powder gets wet, it will clump together and form lumps, with obvious glue edges appearing on the edges of the pattern. The solution is to moisture-proof the hot melt powder, or bake the dampened powder for a while, sift it, and then add it to the powder shaker.
4. Humidity Issues
Excessive air humidity due to weather conditions will cause the white ink to dry slowly. If the white ink is too wet, too much hot melt powder will stick to the edges of the pattern, forming powder edges and glue edges. The solution is to choose a DTF printer and powder shaker with a front drying system.
5. Static Electricity Issues
If the machine is not grounded, the static electricity on the DTF film will be greater when the weather is dry, and the problem of powder sticking may easily occur. The solution is to connect the grounding wire to the machine.
6. Machine Issues
If the above factors are ruled out and there is still unclean hot melt powder on the DTF film, it may be that the quality of the powder shaker is not up to standard.
Hstar 602 DTF Powder Shaker: An Efficient Solution
The Hstar 602 DTF powder shaker is equipped with a pre-baking plate at the front of the powder dusting device, which can effectively reduce powder residue outside the DTF film pattern. Its spiral dragon blade is used to circulate the powder, allowing the hot melt powder to be spread more evenly on the heat transfer pattern, ensuring that the subsequent hot melt glue will be more evenly distributed, increasing adhesion to the fabric, and making the pattern naturally stronger. Moreover, powdering in this way can also reduce the likelihood of powder agglomeration and filter blockage.
Conclusion:
Hstar heat press machines allow you to easily achieve high-definition printing, powdering, and color fixing, drying, and rewinding in one step. Welcome to contact us for more information.
