Ultrasonic inserts for plastics
Our customer, a major player in the aerospace defense sector, asked us to solve a problem with the tear strenght of the insert assemblies for a piece of electronic communication equipment.
The inserts originally chosen for the plastic housing of the equipment did not offer the strenght required for this highly-demanding defence-related use-case.
We carried out a functional analysis of the unit to identify the sources of the problem.
We found that the equipment housing was made of hard plastic (ABS-PC). Our analysis revealed the unsuitability of the inserts initially used. The inserts were intended for soft plastics.
In addition, the boss was not at the correct angle or diameter for the inserts installed. The anchorage was therefore not sufficient to withstand a significant pull-out force.
THE GLOBAL LINKING SYSTEM SOLUTION
Our experts at Inserco proposed specially manufactured ultrasonic inserts that are compatible with hard plastics. These parts have two opposing knurls for improved pull-out resistance.
