Terminal Crimping Fault Handling

To address crimping burrs, the first step is to carefully inspect the crimped terminal appearance using specialized crimp quality inspection tools (such as cross-section gauges or high-magnification microscopes), paying special attention to the edges of the crimping area.

Tip: Once burrs are detected, they must be carefully trimmed with a specially designed fine file or deburring tool. Extra caution is required during operation—apply light and even pressure to avoid excessive trimming that could damage the terminal structure or weaken the metal strength in the crimped area. After trimming, perform another visual and cross-sectional inspection to confirm that the burrs have been completely removed and no new deformation has been introduced.

Additionally, selecting crimping dies that meet specifications and are in good condition, along with regular maintenance, is the fundamental measure to prevent the occurrence of crimping burrs. For copper and aluminum terminals, note their hardness differences. Crimping parameters (such as force and height) must be strictly set according to the terminal manufacturer’s specifications. Since aluminum is softer, improper parameters are more likely to cause burrs or deformation.
