Enabling In-Process Validation of Bump and Taper Features in Extrusion

Extruded products with bumps, tapers, and complex profile transitions present unique challenges for dimensional verification. Traditional inspection methods rely on post-processing and manual measurements across multiple stations, increasing inspection time and impeding startup, resulting in excess scrap.

The new Bump and taper solution from LaserLinc provides in-process measurement of complex extrusions using a unique virtual ring gauge. This method identifies and measures feature transitions and feature lengths during manufacturing, allowing operators to quickly dial in production. By doing so in a way that matches traditional off-line checks, quality can be assured in process.

Correlating length, diameter, and ovality measurements at a single location and synchronizing them with the bump-and-taper process provides a unified view of part geometry during production. Defining a zone for each section of the product profile supports measurement and verification of designs of unlimited complexity and detailed tolerance requirements.

Real-time measurement enables parts to be accepted or rejected in process based on defined criteria. The system can also automate part sorting, even when multiple parts are present between measurement and sorting locations. Quality is documented using customizable spreadsheet-based reports and measurement logs. OPC makes the data accessible by external systems. In addition, an optional closed-loop control feature helps maintain product quality after startup.

By converting what has traditionally been a multi-step, post-process inspection workflow into a synchronized, recipe-driven in-process solution, LaserLinc’s Bump and Taper solution enables manufacturers to produce bump & taper extrusions consistently, with confidence.
