| Abstract: | Aiming at the injection moulding of ultra-thin automotive door trim with the wall thickness of 1.8 mm,combined with actual mould trial,finite element simulations and practical experience,the defects such as the flash,shrinkage,glossiness difference,the mark of ejector pin and the oversize of plastic part were studied.By optimizing the structure of the mould and plastic parts,the injection moulding defects of the thin-walled automobile door trim were improved,and the actual production requirements of the plastic parts had were met. |
