When comparing heat staking vs ultrasonic welding, start with the joint function: both methods join plastic assemblies, but they create the joint differently. Heat staking softens a molded boss so it can form a retaining head around a second component; ultrasonic welding fuses compatible plastic interfaces through vibration and pressure. The choice depends on whether the assembly needs mechanical retention, a continuous seam, service access, or a controlled appearance\u2014not on which process sounds faster.<\/p>\n
