- Pressure failure
- Some places are polished uneven or not in place.
- The treatment agent or adhesive coating is not uniform, lack of glue, lack of treating agent, etc.
- Fitting and pressure are not timely.
- The curing agent added is uneven.
- Pressure should be in place, pressure time and pressure should be enough
- The material that needs to be grind, should be polished evenly. Let the material have enough rough surface
- The adhesive should be coated evenly, without lack of glue, thick and thin, without adhesive.
- Treatment agent treatment should be in place and can not be leaked
