主 题：Metal-plastic direct joining Micro-/nano-structured surface Injection molding Active venting Mold cavity pressure measurement
摘 要：A surface micro-/nano-structured metal plate can be joined with an injection molded plastic piece in a mold,which has been named injection molded direct joining(IMDJ).The injected plastic melt infiltrates the micro-/nano-structure,e.g.,a porous structure with micro/nano pores,on the metal plate while flowing in the mold cavity where the metal plate is *** solidification of the plastic,the metal and plastic materials are directly joined via the micro-/nano-structured metal *** air is trapped by the plastic melt,it is easily imagined that the air in the mold cavity prevents the melt plastic from contacting the metal surface and infiltrating the micro-/nano-structure,which could result in poorer joining *** avoid the prevention of the air for the better joining performance,the present study proposes a system actively venting the mold cavity during injection *** apply the active venting to IMDJ,venting and sealing systems were newly *** addition,a system measuring air pressure of the mold cavity was *** proposed system was evaluated by a measurement of joining strengths of IMDJ specimens that were produced under various *** the results,it is concluded that the active venting does not necessarily have a positive effect in any cases:the effect depends on the type of surface micro-/nano-structure.
