1. Raw material
The leather is rigorously checked and selected. Marluvas only acquires first quality parts, according to the normative requirements.
The parts that constitute the leather are cut: the vamp, the pipes, the bead, the latch and the collar. Insoles and inner linings are also cut.
3. CA Engraving
Each part is crafted to be sewn. The footwear receives the Certificate of Approval (CA) number issued by the Ministry of Labor and, if necessary, the certificate of European and American entities.
With the parts prepared, the time comes for the topstitching, that is, the stitching. It should be made properly to ensure comfort, safety and durability.
5. Intermediate phase
The buttresses, eyelets and rivets, in addition to the mold of the curvature of the foot, are placed. The mounting insole also leads to identification of the production sheet, allowing the tracking of the footwear.
In the assembly sector, the insole is fixed to the leather by means of the Strobel system. Now the mold is placed in the leather and safety equipment such as the toe cap and steel insole are also placed.
After the assembly process, the footwear is abraded to receive the injection of the sole.
8. Injection of the sole
Already assembled, the leathers are placed in the injectors and receive, through the direct injection process, the bidirectional polyurethane soles.
The molds are removed, the leather receives a layer of grease and is brushed, for greater durability. Immediately afterwards, the hygienic insoles are placed. Finally, the shoes are identified and packed for shipment.
10. Quality Control
Footwear is checked thoroughly before packaging.
The last stage is the collective packaging. Throughout the process, Marluvas does its best to ensure consumer protection and maximum comfort.
