Frequently Asked Questions About Aesthetic Analysis of Metals
What is aesthetic analysis of metals and what is it used for?
Aesthetic analysis of metals is a set of specialised tests that evaluates the visual quality, uniformity and durability of surface finishes on metal parts, verifying that they meet the aesthetic acceptance criteria established for each sector or client. It serves to detect defects such as gloss irregularities, colour differences, loss of adhesion or marks that are imperceptible to the naked eye but nevertheless generate complaints or rejections on the production line. At Infinitia we apply it both during supplier validation stages and in the resolution of failure analysis already detected.
What types of metal finishes can be analysed?
At Infinitia we analyse any type of metal surface finish: mirror polishing, satin, brushed, decorative anodising, shot blasting, laser texturing, industrial paints and varnishes, chrome plating, PVD coatings and anti-corrosion treatments. Each finish requires specific testing protocols (glossimetry, colorimetry, adhesion tests or abrasion tests) which we adapt according to the sector and the client’s technical specifications. We also work with precious metals such as gold, silver and platinum in high added-value design applications.
What standards apply to the aesthetic analysis of metals?
Aesthetic analysis of metals tests are carried out in accordance with internationally recognised standards, including ISO 1461 (hot-dip galvanising), EN ISO 7599 (anodising of aluminium), ISO 2409 (cross-cut adhesion test), ISO 4628 (assessment of coating deterioration) and ASTM standards for scratch resistance and gloss testing. In sectors such as automotive or aerospace, client-specific or supply chain specifications (OEM) also apply. At Infinitia we adapt the testing protocol to the required standard in each case, issuing technical reports that can be used in homologation processes or raw material quality parameter definition.
How are surface defects in metals detected?
Surface defects in metals are detected by combining standardised visual inspection with optical metrology equipment such as glossmeters, colorimeters and high-resolution optical microscopy. At Infinitia we also apply fractography and microscopy testing to identify the nature and origin of anomalies, whether due to the manufacturing process, the treatment applied or the quality of the raw material. This multi-scale analysis makes it possible to distinguish between superficial cosmetic defects and alterations that also compromise the functionality or protection of the component.
What distinguishes aesthetic analysis from coating or galvanising analysis?
Aesthetic analysis of metals focuses on the visual and perceptual parameters of the finish (homogeneity, gloss, colour, texture and absence of visible defects) whereas analysis of galvanised, anodised and other coatings examines in depth the composition, thickness and protective properties of the treatment. In practice, both approaches are complementary: a technically correct coating may present unacceptable aesthetic defects, and vice versa. At Infinitia we often integrate both analyses when the client requires a complete validation of the finish, both functional and visual.
In which sectors is aesthetic control of metals most critical?
Aesthetic control of metals is especially critical in automotive, aerospace, consumer electronics, home appliances and architecture and interior design, sectors where product appearance directly influences quality perception, purchasing decisions and the rate of after-sales complaints. In automotive, for example, chromatic tolerances between parts on the same assembly line are strictly defined; in consumer electronics, any variation in the anodising of an aluminium casing can lead to the rejection of an entire batch. Infinitia has proven experience across all these sectors, drawing on a methodology that combines specialised testing with materials characterisation to deliver actionable conclusions in each case.
Can ageing tests be carried out to predict how a finish will change over time?
Yes, accelerated ageing tests make it possible to predict how a metal finish will evolve under real-world conditions such as humidity, UV radiation, salt spray or thermal variations, within reduced timeframes. At Infinitia we have climatic, salt spray and UV chambers that simulate exposure cycles equivalent to months or years of real service. These tests are especially relevant for validating finishes in outdoor environments (facades, street furniture, vehicle components) or in aggressive settings such as industrial kitchens or aeronautical installations. The results are complemented by accelerated ageing and durability testing applied to all types of materials.
Is it possible to compare the finish of different suppliers to select the best one?
Yes, aesthetic analysis of metals is a highly effective tool for benchmarking suppliers and selecting the one that offers the most consistent, durable and specification-compliant finish. At Infinitia we design comparative testing protocols with which we evaluate samples from different manufacturers under identical test conditions, generating objective data that supports the purchasing decision. This methodology is particularly useful when onboarding a new supplier or when auditing the quality of externally contracted treatments.
When should I commission an aesthetic analysis of metals?
You should commission an aesthetic analysis of metals when you detect appearance-related complaints on already-delivered parts, when you want to validate a new supplier or a process change before launching serial production, or when you need to define objective acceptance and rejection criteria for your quality department. It is also advisable to carry it out preventively before submitting a product for homologation or when the finish is a competitive differentiator in your market. At Infinitia we work as an external technical partner: we do not just carry out the tests, we interpret the results with an industrial perspective and support the client from diagnosis through to solution, which complements well the more normative approach of an accredited laboratory or the research-oriented focus of a technology centre or university.
Can already-manufactured parts be analysed, or only during the production process?
Aesthetic analysis of metals can be applied at any point in the product lifecycle: both on already-manufactured parts in use and at intermediate stages of the production process. In fact, some of the most common cases Infinitia handles arrive precisely when a problem has already been detected (a rejected batch, a client complaint or a line incident) and it is necessary to identify its origin quickly. In these cases we act as an external technical partner that not only characterises the defect but also helps determine whether the cause lies in the base material, the applied treatment or the process conditions, thus guiding corrective actions. For those who prefer to be proactive, we also design custom testing protocols integrated into the production workflow to detect deviations before they become a problem.
Do Infinitia's technical reports have validity for legal or expert witness proceedings?
The technical reports issued by Infinitia rigorously document the tests carried out, the methodology applied, the results obtained and the resulting technical conclusions, and can be used by a court-appointed expert as documentary evidence for the preparation of their expert report. It is important to clarify that Infinitia issues specialised technical reports, not expert witness reports: the legal responsibility for the expert’s opinion always rests with the duly qualified expert. This distinction does not limit the usefulness of the technical report, which in many cases constitutes the most solid analytical evidence on which the expert bases their conclusions. If your case has legal implications, we recommend consulting us from the outset so that the scope of the analysis can be tailored to your needs.
What are the usual turnaround times for results?
The usual turnaround times for an aesthetic analysis of metals range from 1 to 4 weeks from receipt of the samples, depending on the technical complexity of the test, the number of parameters to be evaluated and the need for accelerated ageing cycles, which by their nature require exposure time. For urgent situations, at Infinitia we offer an express quotation option that allows results to be obtained within 24 to 72 hours in cases where the nature of the test permits. If you have a deadline or a critical production situation, let us know when you get in touch and we will factor it in from the very beginning.
