The reasons for superfluous thin wings generated at the edge of workpieces and relevant solutions
  Reasons Solutions
1 Excessive injection  Reduce the volume of injected glue
2 Lack of clamping force  Increase clamping force
3 Excellent fluidity of material (e.g. PA/PP/PE/POM) Change material/reduce mould temperature/reduce material temperature/reduce injection pressure 
4 Parting surface is not tight enough. It has gaps or debris  Adjust mould. Redevelop the parts that are not closely fitted or remove debris 
5 There is a large gap between sliding parts in mold cavity and core Adjust mould. Reduce the gap between sliding parts in mold cavity and core
6 6. The closing part of mould is overcut Weld and rework the overcut parts 
7 Low strength or rigidity of mould Increase the thickness of template/increase templates or add support pillars 
8 Low parallelism of bearing surface  Trim the mould so that all bearing surface can be parallel to each other 
9 The mould is not completely compacted during installation Reinstall and compact the mould
