Uneven sheet thickness is the most common fault in medium-thin sheet production, manifested as inconsistent thickness in the middle and edge of the sheet, or thickness fluctuation in the length direction. The main causes include unbalanced die head material flow, worn calendering rollers, inaccurate gap calibration and unstable extrusion speed. The targeted solution is to fine-tune the die head shunt bolts to balance melt output, clean and polish the surface of calendering rollers, recalibrate the servo calendering gap parameters, and stabilize the host extrusion speed to ensure uniform material supply.
For periodic thickness deviation caused by parameter jitter, update the PLC operation program, calibrate the temperature and pressure sensors, and eliminate parameter drift faults to ensure long-term stable thickness control accuracy.
6.2 Sheet Surface Defects (Bubbles, Particles, Scratches)
Sheet bubble defects are mainly caused by excessive moisture in raw materials and incomplete drying. The solution is to adjust the parameters of the raw material drying unit, extend the drying time, and ensure that the raw material moisture content is controlled below 0.02% before extrusion. Surface particle impurities are caused by unclean raw materials, blocked die head flow channels and aging carbonized materials. It is necessary to regularly clean the extrusion screw and die head, replace filter screens in time, and strictly control raw material purity.
Surface scratches are mostly caused by foreign impurities on the surface of calendering rollers and guide rollers. Regularly clean the roller surface and keep the production environment clean to ensure smooth and flat sheet surface molding.
6.3 Sheet Warping, Deformation & Poor Flatness
Sheet warping and deformation are mainly caused by inconsistent cooling speed on the upper and lower surfaces of the sheet and uneven internal stress. The solution is to adjust the temperature parameters of the upper and lower cooling rollers to ensure synchronous and uniform cooling of the sheet. Appropriately extend the cooling setting time to eliminate internal molding stress. For deformation caused by unreasonable traction speed, adjust the matching degree of traction speed and extrusion speed to avoid sheet stretching deformation.
After parameter optimization, the flatness of finished sheets is significantly improved, completely meeting the flat laying requirements of packaging blister processing and building construction.
6.4 Low Production Efficiency & Unstable Continuous Operation
Low production efficiency and frequent equipment shutdown are mostly caused by aging transmission parts, blocked feeding system and unreasonable parameter matching. Regularly lubricate and maintain the transmission bearings and servo motors of the equipment, clean the feeding pipeline blockages, and optimize the matching parameters of extrusion, calendering and traction speed. The standardized parameter formula can effectively improve the continuous operation stability of the equipment, increase the effective operating time, and maximize production efficiency.
