laboratory and production


Technology reference

To meet the high quality standards demanded by the market, Marluvas maintains a complete laboratory, with evaluation systems for physical-mechanical tests and equipment for the analysis of restrictive substances. Both shoes and their components are tested. We evaluate performance in terms of quality, strength, impact, abrasion, among others.

The team of professionals is formed by technicians trained in laboratories accredited to the Ministry of Labor, ensuring the reliability of the reports and issued. These documents are used as a reference for national and international certifications.


Follow the complete production of Marluvas safety shoes, from the arrival of the raw material
to the final packaging.

1. Raw material

Leather is rigorously checked and selected. Marluvas only purchases top quality parts, in accordance with regulatory requirements.

2. Cut

The parts that make up the upper are cut: upper, upper, barrel, tongue, collar and collar. Insoles and lining are also cut.

3. CA recording

Each part is worked to be sewn. The footwear receives, via laser engraving, the number of the Certificate of Approval (CA) issued by the Ministry of Labor and, if necessary, the certificate of European and American entities.

4. Backstitch

With the pieces ready, it is time for the backstitch, that is, the seam. It must be done properly to ensure comfort, safety and greater durability.

5. Intermediate phase

The buttresses, eyelets and rivets are placed, in addition to the mold of the curvature of the foot. The mounting insole also carries the identification of the production sheet, allowing the tracking of the shoe.

6. Assembly

In the assembly sector, the insole is fixed to the upper using the Strobel system. Now, the formwork is placed on the leather and safety equipment, such as the toecap and steel insole, are also placed.

7. Asperagem

After the assembly process, the shoes are roughened to receive the sole injection.

8. Sole injection

Already assembled, the uppers are placed in the injectors and receive, through the direct injection process, the polyurethane bi-density sole.

9. Finishing

The molds are removed, the leather receives a layer of grease and is brushed, for greater durability. Then, the hygienic insoles are placed. Finally, the shoes are identified and packaged for the expedition.

10. Quality Control

Shoes are checked strictly before packaging.

11. Packing

The last step is that of collective packaging. Throughout the process, Marluvas does its best to guarantee the consumer maximum protection and comfort.
