Key Points and Quality Control of Precision Metal Insert Overmolding
Precision metal insert overmolding is a special molding process that pre-places metal inserts into the mold cavity and then injects liquid silicone to achieve a firm bond between the two materials, which is widely used in automotive, medical, consumer electronics and other fields with high requirements for sealing and structural strength. This paper sorts out the core operation points of the process, analyzes the causes of common problems such as insufficient bonding force, flash, and insert offset, and provides corresponding quality control solutions to help manufacturers improve product yield.
