Plastic Part Inspection

Plastic Part Inspection with
ZEISS METROLOGY

Measure plastic components for dimensional variation, warpage, CAD deviation, surface geometry and internal defects with ZEISS 3D scanning, CMM and industrial CT solutions.

Why Metrology Matters

Plastic parts can change. Your measurements shouldn’t.

Plastic components are influenced by material behaviour, tooling, cooling conditions, process parameters and environmental factors.

Shrinkage, warpage, sink marks and dimensional variation can affect assembly, functionality and product reliability.

ZEISS metrology solutions help manufacturers compare actual components against CAD data, identify deviations and establish repeatable inspection workflows.

Inspection Challenges

What needs to be measured?

Plastic components can vary in form, dimensions and internal structure. The inspection method should match the quality problem you need to understand.

01

Warpage & Deformation

Identify changes in component shape caused by material behaviour, cooling and manufacturing conditions.

02

Dimensional Variation

Verify critical dimensions and determine whether manufactured components remain within specification.

03

CAD Deviation

Compare complete component geometry against the nominal CAD model to identify areas of deviation.

04

Complex Surfaces

Capture freeform surfaces and detailed geometry that may be difficult to evaluate using discrete measurement points alone.

05

Internal Defects

Inspect hidden geometry, wall thickness, voids and other internal characteristics without destroying the component.

06

First Article Validation

Validate new or modified plastic components against design requirements before series production.

Inspection Capabilities

What can you inspect?

Different inspection requirements call for different measurement approaches. ZEISS technologies can be selected according to component geometry, tolerance requirements and inspection objectives.

01 / DIMENSION

Dimensional Inspection

Verify critical dimensions against drawings, specifications and design requirements.

02 / GD&T

Geometric Tolerances

Evaluate form, orientation, location and other defined geometric requirements.

03 / FORM

Warpage & Deformation

Identify deviations across the complete surface of moulded components.

04 / CAD

Part-to-CAD Comparison

Compare measured component geometry with the nominal CAD model.

05 / SURFACE

Surface Geometry

Capture freeform and complex surfaces for comprehensive geometric evaluation.

06 / INTERNAL

Internal Features

Inspect inaccessible structures, wall thickness and internal geometry using CT technology.

07 / ASSEMBLY

Fit & Alignment

Verify interfaces and dimensional relationships between components and assemblies.

08 / FAI

First Article Inspection

Validate newly manufactured or modified components before production is scaled.

ZEISS Inspection Technologies

Choose the right technology for the inspection.

3D scanning, CMM and industrial CT each provide different measurement capabilities. The right choice depends on what you need to measure and how the component needs to be inspected.
