Industrial metrology and dimensional inspection services
Validating the precise geometry of a fabricated part is the definitive step in successfully closing the engineering loop. To guarantee absolute compliance with your original design specifications, Techmetal operates a highly advanced, strictly temperature-controlled (20°C) department dedicated entirely to industrial metrology. We function exclusively as a B2B subcontract manufacturing partner, meaning our metrology services are seamlessly integrated into the production of your custom stainless steel components.
By maintaining total oversight of the measurement and validation process in-house, we effectively eliminate the logistical need for third-party quality testing. Our dedicated dimensional inspection services ensure that every single outsourced part, welded assembly, or processed tubular structure perfectly matches your technical drawings before it ever leaves our facility. This rigorous internal oversight mitigates downstream supply chain risks and actively safeguards the operational integrity of your final industrial application.
Precision CMM inspection and 3D dimensional verification
When dealing with complex tubular profiles, irregular radii, or intricately welded structures, traditional hand-held measurement tools are fundamentally insufficient.
To consistently achieve the highest standards of precision metrology, our testing environment is equipped with state-of-the-art contact and non-contact scanning hardware. A cornerstone of this analytical capability is our rigorous Coordinate Measuring Machine (CMM) inspection protocol, which meticulously evaluates the physical characteristics of the metal against the strictest engineering tolerances.
To execute flawless dimensional verification across complex production batches, our technicians utilise:
- 3D laser scanners: these optical systems perform high-resolution point-cloud to CAD comparisons. This instantly maps and identifies any minute geometric deviations against your original 3D STEP files;
- profile scanners and tactile probes: guaranteeing that even the most challenging cross-sections, blind cavities, and structural contours conform exactly to the required design parameters.
Through these advanced tools, we provide comprehensive CMM inspection services.
Manufacturing quality control and surface finish analysis
To guarantee the absolute reliability of your B2B supply chain, our manufacturing quality control protocols extend far beyond basic geometric validation. We recognise that the metallurgical structure and the exterior condition of a custom part are just as critical to its performance as its dimensional accuracy.
Therefore, our comprehensive quality control services include:
- Positive Material Identification (PMI): utilising two highly precise mass spectrometers to conduct rigorous material analysis, independently verifying the exact chemical composition of the stainless steel alloy;
- Non-Destructive Testing (NDT): for critical fluid dynamic applications, we deploy advanced video endoscopes to conduct thorough internal visual checks (VT) of all tubular TIG welded joints, ensuring complete root penetration and the absence of micro-crevices;
- roughness testing: to objectively certify the outcome of our electropolishing or mechanical finishing treatments, our metrology room is equipped with three dedicated roughness testers. These accurately measure the final surface profile (Ra), confirming strict adherence to your hygienic or high-vacuum specifications.
First article inspection and comprehensive measurement reports
Supplying fabricated components to highly regulated industries—particularly the biotechnology and Food & Beverage sectors—requires robust, transparent, and flawless documentation. We do not merely manufacture and test parts; we provide the exhaustive traceability data required to validate your entire engineered assembly. For new complex projects, we routinely execute a formal first article inspection (FAI), rigorously evaluating the initial off-tool component to ensure the entire manufacturing process is perfectly aligned with your design intent before full-scale production begins.
To fully support your regulatory compliance and quality assurance teams, our engineering department is fully equipped to compile advanced validation packages, including Production Part Approval Process (PPAP) documentation and Process Failure Mode and Effects Analysis (PFMEA). Upon request, we furnish a highly detailed dimensional inspection report alongside standard EN 10204 3.1 material certificates.

Integrated quality inspection services for stainless steel components
Quality assurance is never treated as a secondary or isolated phase; it is the fundamental pillar that underpins our entire B2B manufacturing workflow. By choosing Techmetal, you benefit from fully integrated quality inspection services tailored specifically to custom stainless steel assemblies. Rather than relying on disparate external suppliers for validation, parts that have just completed our advanced laser cutting, precision tube bending, TIG welding, pickling, or electropolishing processes transition immediately into our metrology room. This seamless internal routing guarantees that strict dimensional control is maintained at every single stage of production, ensuring absolute defect elimination before any batch is cleared for final dispatch.
To further reassure our corporate clients of our operational reliability, our engineering and management framework is rigorously audited. Our facility is fully certified to ISO 9001, ISO 14001, and ISO 45001 standards, alongside an EcoVadis rating and full structural compliance with the DPR 231 organisational model.
