Bopp Tape Transfer Coating Machine

Bopp Tape Transfer Coating Machine

1. High precision alloy steel die head make sure the customer can get the best coating effection.

2. Total Machine is controlled by  PLC.Precision control coating speed and glue amount.

3. Increase the film function in some glue or substrate is not suitable for direct knife coating that realize 2 kinds of craftwork (knife coating and film coating.) on one machine.

First, the role of coating:
In the battery production process, the roll of the substrate, copper foil, aluminum foil coating
A layer of a specific function of the slurry. Ensure that the surface of the pole piece is flat, smooth, uniform in dressing, good in adhesion, dry, no material, no material, no dust, no bubbles and drying and winding.

Fourth, the process requirements: positive and negative electrode coating:

Double-sided total dressing density:
1. The first coating length deviation is ≤ 2 mm, and the coating gap deviation is ≤ 1 mm. 2. The maximum misalignment between the second side and the first side is ≤ 1 mm.
3. The maximum deviation of the thickness of the coated single film is ≤3um, and the maximum deviation of the thickness of the double film is ≤6um. 4. The maximum deviation of the density of the coated single film is ≤ 4%, and the maximum deviation of the density of the double film is ≤ 8%. 5. The maximum error of coating tailing is ≤1mm.
6, the film surface should be flat, can not appear dry cracks, wrinkles, particles, streaks. 7. Coating width = single strip width multiplied by the maximum number of coatable sheets + 5 ~ 10mm.
