What are Checking Fixtures

A checking fixture is a dedicated inspection tool used to verify whether a component meets predefined dimensional and positional requirements.

These systems are typically used when a process:

  • Requires fast and repeatable quality checks
  • Needs validation directly on the shop floor
  • Must minimize operator influence
  • Demands consistent inspection results

By combining precise locating, clamping, and measurement references, a controlled inspection process is created where speed, reliability, and quality assurance come together.

At Fixar, we start by analysing the inspection requirements, tolerances, and operator workflow to define the most efficient checking method. We then design a fixture that ensures reliable positioning, easy operation, and consistent validation results.

The process typically includes:

  • Analysis of inspection requirements and tolerances
  • Concept development and fixture engineering
  • Integration of locating and clamping systems
  • Ergonomic and operator-focused design
  • Manufacturing and assembly
  • Testing and validation

After delivery, we support implementation and ensure the fixture performs reliably within the production environment.

Fixar works in a transparent and practical way, ensuring alignment between inspection requirements and production realities throughout the project. Clients remain involved during validation and approval stages to guarantee the right solution.

The result is a checking fixture that:

  • Enables fast and reliable inspections
  • Ensures stable and repeatable results
  • Is robust, intuitive, and easy to use

After installation, we provide documentation and support to ensure efficient long-term operation.

FRequently asked questions

A checking fixture verifies if a part is OK or NOK (pass/fail) by checking fit or position.

A measurement fixture holds the part in the correct position so you can measure exact values like dimensions or tolerances.

In short:

  • Checking fixture = pass/fail
  • Measurement fixture = exact measurement

Yes. FiXar remains involved after delivery through start-up support, optimisation, technical assistance and maintenance advice. This ensures that the industrial automation system continues to perform reliably throughout its lifecycle.

Yes. FiXar integrates vision and measurement systems when required for process control, quality verification or positioning. These systems are connected to the automation and PLC architecture for fully automated inspection and control.

Traceability and data logging are integrated through data exchange with existing systems, such as MES platforms. This allows production data, process parameters and quality information to be automatically recorded and monitored.

FiXar primarily works with Siemens TIA Portal for PLC-based industrial automation. This platform enables the development of reliable, maintainable automation software and smooth integration into existing production environments.

FiXar primarily works with Siemens TIA Portal for PLC automation, depending on the project requirements.
