Form Scan and Dimensional Analysis of Molded Electronic Housing

Executive Summary

Modern electronics enclosures require precise dimensional integrity to ensure proper fit, assembly, and function within compact and complex devices. EDM Intelligent Solutions provides advanced non-contact 3D metrology services that allow micron-scale form measurement of molded components. This report details our inspection methodology for an engineered plastic electronic housing using the MVi5 3D Metrology Center.

Overview of 3D Metrology Capabilities

Our 3D scanning technology captures detailed surface data to allow comprehensive form measurement of components with complex geometries. Dimensional attributes such as radii, angles, slots, and step heights can be extracted from cross-sectional profiles created within the 3D dataset.

Key capabilities include:

Non-contact 3D scanning for high-resolution form analysis
Profile slicing for detailed dimensional extraction
Applicable to plastics, metals, and hybrid assemblies
CAD comparison and form deviation analysis

Form Scan Inspection Process

Step 1: Capture Full 3D Data

The first step of the inspection involves capturing a complete 3D surface scan of the electronic housing using our MVi5 3D Metrology Center. This system collects dense point cloud data across all visible surfaces of the part with micron-level accuracy.

Step 2: Generate Cross-Sectional Profiles

Once the 3D model is created, virtual profile slices are made through key areas of the part to extract dimensional data. This step allows for precise measurement of features such as wall thickness, slot width, angles, and internal contours.

Step 3: Form Measurement and Dimension Extraction

Dimensional measurements are then taken from each profile section. Typical metrics include radii, step heights, angular deviation, and symmetry. All measurements are compiled and evaluated for tolerance conformance.

Step 4: Reporting and Analysis

Finally, the data is visualized and formatted into a detailed inspection report. Results can be used to validate tooling, identify process variation, or compare against CAD models for design verification.
