Disadvantage 1: Relatively high manual dependence, resulting in a natural scrap rate of 8%–15%
Solution: We adopt standardized water temperature, solvent dosage and film activation time parameters for batch production. Equip fixed water tank tooling and positioning brackets to stabilize operation standards. All finished products undergo secondary trimming and inspection to screen defective products in advance and reduce final rejection rate.
Disadvantage 2: Prone to pattern shifting, wrinkling and bubble warping during film wrapping
Solution 1: Strictly control water temperature at constant temperature and standard solvent spraying dosage to avoid excessive or insufficient film activation.
Solution 2: Adopt segmented slow-fitting operation for complex curved surfaces, manually guide film stretching, and squeeze out residual water and bubbles step by step with soft scraping tools.
Solution 3: Use high-elasticity customized hydrographic films for special-shaped parts to reduce wrinkling and tearing during fitting.
Disadvantage 3: Unable to present tiny text, fine logos and ultra-precise lines
Solution: Adopt hybrid process matching. Complete the overall large-area wood grain/camouflage texture via water transfer printing, and supplement tiny text and fine logo details through pad printing or UV printing. The combined process achieves both full-surface texture sense and high-precision detail performance.
Disadvantage 4: Slight edge overflow and residual film marks easily appear on assembly splicing positions
Solution: Pre-set process reserved edges for splicing parts, and match post-process fine trimming and edge polishing to ensure neat and seamless assembly effect.
