Poor interface bonding between two materials in two-color '2079851475616104452
Problembeschreibung
The two materials of the two-color injection molded product delaminate at the interface
Ursachenanalyse
The two materials are thermodynamically incompatible; the first shot is over-cooled and the second shot cannot fuse effectively; interface temperature is too low
Lösung
Select material combinations with good compatibility; control the cooling degree of the first shot so that its surface still has sufficient temperature; optimize injection timing
Wichtigste Erkenntnis
The interface bonding strength of two-color '2079851475616104452 determines the overall performance of the product
