Recently audited a plywood factory and made the plywood inspection , found that there are many hot pressing indentation problems, for our professional inertia, we went to their hot press process line and studied and found a lot of problems.
1. Did not clean up the rubbish on the hot plates in time.
2. Core veneer edge of the excess core veneer is not properly cut off, resulting in the potential risk of hot pressing indentation.
According to the requirements of the veneer core lay-up production process, need to cut the excess core veneer, especially the longitudinal part of the excess core veneer part must be cut off, if not cut in the follow-up hot pressing process will create series of quality problems, such as the pre-pressure Of the plates to the hot-rolled steel plate when the excess part of the core veneer if the break is not timely clean-up, then it is easy to cause alien garbage indentation.In terms of saving, we can cut off the excess core veneer used to repair the dead cave or other digging place /patches.
These are a factory management problem.
