The reasons for the defects of the heat transfer pattern of the wood grain transfer machine may be:
1. The level of the rubber roller is not adjusted properly, resulting in uneven heat transfer pressure.
2. Unstable gas source causes pressure instability.
3. The adhesive of the thermal transfer film is uneven.
4. The inner hole of the rubber roller is too large, and the expansion after heating causes the rubber roller to shake and eccentrically, and the transfer pressure is uneven.
5. The equipment is not stable during transfer, causing the thermal transfer film and the transferred door to move.
6. The surface of the door panel is not clean, with oil stains or dust.
