Common problems and solutions for leather pasting
Possible causes and solutions for the problem
Leather foaming: glue is not completely dry/temperature is too high. Adjust the pre drying time and reduce the hot pressing temperature
Edge lifting: Insufficient adhesive strength/uneven pressure, use high adhesive instead, optimize compression parameters
Leather deformation/indentation: excessive pressure/high temperature reduces pressure and shortens hot pressing time
Glue leakage: excessive glue application reduces the amount of glue or uses high solid content glue instead
summarize
The key to hot pressing leather lies in:
Pre treatment of substrate and leather (cleaning, roughening, primer).
Adhesive selection and coating process (matching material characteristics).
Optimization of hot pressing parameters (temperature, pressure, time).
Post processing and quality inspection (trimming, weather resistance testing).
By controlling process parameters, high-quality and high-yield leather bonding products can be achieved.
