The value of leather quality control in tanneries

The strategic importance of leather quality control in tanneries translates into maximum efficiency in every production phase, meeting market demands and solidifying their brand. Let’s explore the importance of quality control in leather processing.


What is the leather quality control process

Within the tanning production, leather quality control represents a delicate and crucial phase for the entire supply chain: it involves a series of systematic processes of verification, analysis and monitoring of leather characteristics, with the aim of ensuring maximum adherence to the rigorous quality standards required by the industry.

Quality, in fact, is not a negotiable factor in the high-level tanning industry: every single leather piece that comes out of the processing departments undergoes careful checks to identify even the smallest non-conformities compared to the preset parameters.

Some of the main parameters checked on processed leathers are:

  • Size and area of leather batches, to ensure measurement uniformity;
  • Thickness of the hides, to verify the conformity of splitting and shaving phases;
  • Coloration, to ascertain the uniformity of the dye and absence of chromatic defects;
  • Surface finish, to inspect the aesthetic appearance and quality of coating;
  • Resistance and solidity of chemical treatments applied in the finishing phase.

Only through rigorous and thorough quality checks, it’s possible to prevent defects and irregularities in hides and skins, promptly identifying any anomalies and applying appropriate countermeasures. Constant monitoring of production allows certifying the excellence of each leather, safeguarding the value of products and customer satisfaction.

The leather industry does not tolerate approximations: quality control is therefore an indispensable factor to ensure the reliability and reputation of a tannery in the market.


The importance of quality and challenges in production

Implementing a rigorous quality control system is a priority to increase tanneries’ competitiveness. The very nature of the tanning production process imposes particular challenges in terms of efficiency and quality:

  • Raw hides are extremely delicate and variable: small differences in characteristics can be amplified in subsequent leatherworking processes, generating defects and non-conformities to production standards.
  • The tanning process involves complex chemical and mechanical steps: even the slightest variation in process parameters can cause quality problems such as color defects, irregular thickness or lack of adherence of treatments.
  • Market demands for quality are increasingly stringent: brands aim to produce products of absolute excellence, and likewise, consumers are becoming more demanding and attentive to the smallest aesthetic and performance-related details.

As of today, for a tannery, leather production quality represents much more than just an added value: it is a necessity to remain active in the market, protect the company brand and fully meet the expectations of the most ambitious customers.


Quality control in the leather spraying process

In particular, leather spraying represents one of the most critical phases of the entire production cycle: in this process, hides are treated with various chemicals that define both the aesthetic appearance and the performance and resistance characteristics.

During the spray finishing process, utmost attention must be paid to leather quality control: defects and imperfections, even if minimal, can compromise the excellence of the finished product. Some of the main critical points are:

  • Uniformity and consistency of the applied spray painting layers, in terms of quantity and distribution of chemicals;
  • Correspondence of color paint to the reference sample, to prevent problems or chromatic variations such as metamerism;
  • Optimal operation of spray guns in order to avoid drips, streaks or excess overspray on treated hides;
  • Correct adhesion and resistance of the spray layers, to ensure the solidity of the finishing treatment over time.

Only a perfectly controlled spray painting process can guarantee impeccable surface finishes and reproducible results on a large scale for the entire tanning production.


GER Elettronica systems for tanning production

To address the challenges of quality control during leather finishing and the entire production process, tanneries can rely on cutting-edge technological solutions capable of monitoring hides at every stage of work, from initial splitting to final packaging.

In this context, GER Elettronica offers its decades of experience in the industry by manufacturing machinery and systems for full control of tanning production: our automated lines allow for real-time data analysis and collection of thickness, area and defects of hides and skins, with the aim of increasing leather production efficiency.

In particular, BE.SPRAY represents the most innovative integrated system for managing and monitoring the leather spray finishing phase, consisting of:

  • IRIS, a system that allows precise and accurate colorimetric control, identifying and quantifying the slightest chromatic differences in hides compared to reference samples, to ensure uniformity of hides throughout production;
  • I.GUN, a system that constantly monitors the correct operation of spraying guns inside booths, detecting any anomalies in spray uniformity in real-time and eliminating waste or machine downtime;
  • I.CONTROL, a high-resolution spray control system, capable of measuring the areas of hides in processing with extreme precision and optimizing the application of chemicals, reducing consumption and overspray.

Adopting GER Elettronica solutions enables tanneries to certify the quality of every single batch, while simultaneously increasing productivity, efficiency and competitiveness.
