Dimensional Inspection of Custom Components

Since 2025, VR Plast has expanded its services by introducing dimensional inspection of custom components using the Hexagon 7-axis Absolute Arm, an advanced instrument for quality control, tactile measurement, and high-resolution 3D scanning.

The introduction of this technology enables faster and more accurate verification of the geometric conformity of machined components, both in plastic and metal, against the specifications defined by the customer in the technical drawing.

More precise quality control for custom components

Dimensional inspection is a fundamental step in ensuring that every manufactured component meets the required design specifications. Using the 7-axis measuring arm, VR Plast can carry out accurate checks on:

• linear and geometric measurements;
• functional dimensions and tolerances;
• profiles, radii, centre distances, and complex surfaces;
• comparative verification between the actual part and the model or technical reference;
• measurement of existing components, even in the absence of complete documentation.

This approach reduces the margin of error in verification processes and improves repeatability, particularly for components with complex geometries or tight tolerances.

Tactile measurement and 3D scanning

The Hexagon Absolute Arm allows operation through both tactile measurements and high-resolution 3D scanning, making the inspection highly versatile depending on the type of part and the objective of the verification.

Tactile measurements are suitable for precise checks on specific dimensions and functional surfaces. 3D scanning, on the other hand, enables rapid acquisition of the component’s geometry and analysis of its overall profile, particularly useful for technical parts, complex shapes, or when comparison with existing samples is required.

Compliance with design specifications

With this service, VR Plast strengthens its ability to ensure that every machined component strictly complies with the dimensional specifications required by the customer.

Inspection can cover not only nominal dimensions but also other parameters specified in the technical drawing, including:

• dimensional tolerances;
• geometric references;
• functional fits;
• surface requirements, where applicable;
• overall consistency of the part with its intended application.

The availability of an advanced measurement system contributes to a higher level of conformity of delivered components and provides concrete support both during initial validation and throughout production checks.

Operational benefits for the customer

The use of in-house dimensional inspection brings clear operational advantages throughout the supply process. In particular, it allows:

• easier identification of dimensional deviations;
• reduction of rework and potential disputes;
• improved traceability of performed inspections;
• support for the production of technical components with tighter requirements;
• increased overall reliability of supply.

For the customer, this means relying on a more structured verification process and greater confidence in the alignment between the designed and manufactured component.

An investment aligned with VR Plast’s technical evolution

The introduction of dimensional inspection using a 7-axis measuring arm is part of VR Plast’s ongoing technical development, aimed at strengthening not only production capabilities but also the level of control and service reliability.

Alongside the machining of custom components, dimensional inspection now represents an additional value for all customers requiring precision, repeatability, and accurate verification of design specifications.
