We loss a lot for this lot until miss shipment and need to postpone to Friday. It will be risk again for the HBB product if do not solve in time.
Production, as discussion, make sure the weight calibrate is done whenever you change the regrind type.
Maintenance, check with process engineer what is the cause of parameter change itself. I do not believe this blender can be changed the set parameter itself, without noone touch it. Please verify and solve asap.
Lab, please include maintenance in loop when get issues of property failure specially %C, Density, OIT, Mechanical property as well.
