Resumen:
Una empresa española de base tecnológica ha desarrollado y obtenido la patente de una tecnología de unión tridimensional para fabricar calzado sin costuras. La tecnología consiste en un método de producción que une de forma tridimensional los componentes de cuero y otros materiales flexibles, sustituyendo el arduo trabajo de costura por un proceso de inyección de polímero que dura unos segundos. Esta tecnología reduce la mano de obra hasta un 70% y mejora el rendimiento del producto, ofreciendo una mayor adaptabilidad, mejores propiedades impermeables y mayor estabilidad tridimensional y durabilidad. La empresa busca compañías con el fin de establecer acuerdos de licencia o comercialización con asistencia técnica.

Tittle:
Innovative footwear production technology based on three-dimensional bonding
Summary:
A Spanish technology based company has developed and patented a tridimensional bonding technology for manufacturing shoes without seams. This technology reduces the labor power up to 70%. The company is looking for companies interested in licensing and/or commercial agreement with technical assistance.
Description:
Three-dimensional bonding technology, which has been developed by the Spanish technology based company, aims at reducing the complexity in the manufacture of footwear in order to allow shoe manufacturers to produce world-class articles without transferring part of production to lower-cost countries.
The technology consists of a production method whereby pieces of leather or other flexible material are joined three-dimensionally at its ends, thus replacing the intensive sewing labor by a few seconds of injection of a polymer.
The procedure is carried out by means of a mold and counter-mold between which space is defined with the shape of the item to be obtained. Once the plastic material is injected through the network of channels, it takes about 5 minutes for the material to cure and then the mold can be opened to remove the finished product.
Overall, the main advantage of this technology over other existing production processes consists in the drastic reduction of production costs, due to the elimination of a considerable number of manual operations, as well as the reduction of the cut materials. Moreover, the technology offers a substantial improvement in product performance with improved adaptability, better waterproof qualities, greater three-dimensional stability and durability.
Taking all the aforementioned points into account, producers of footwear are sought with the aim of establishing a technological collaboration, by licensing and/or commercial agreement with technical assistance, in order to implement this bonding technology in their production systems. The three-dimensional bonding process developed will make easier the production of footwear, plus having a great economic impact for the sector.
Advantages and Innovations:
This technology will produce strong impact on final product quality and on process efficiency by:
- Reduction of mechanical operations on uppers (reduction of labour power up to 70%)
- Improvement of the comfort because of the upper uniform pressure.
- Improvement of the waterproof property due to the absence of seams.
- Elimination of solvent based glues, eliminating problems of toxicity.
- Reduction of the carbon footprint associated with shoe manufacturing.
- Elimination of excess upper material, reduction of material costs up to 52% compared with the traditional manufacturing method.
- Increasing of durability and lifetime.
- Total chafing prevention.
- Improvement of inserts bonding.
- Reduction of production time up to 65%.
- Optimization of bonding between upper and sole.

Partner sought

Type and Role of Partner Sought:
The expected partner is a footwear producer interested on implementing such innovative technology to be allowed to produce in EU/USA. Moreover, it should be borne in mind that cost savings are directly related to the volume of the production batch, since the technology entails certain investment in machinery and molds. This means that the technology would be profitable in production batches per model superior to 1500 pairs.

- Specific area of activity of the partner:
Footwear production.

- Task to be performed:
Manufacture of footwear using the developed technology by licensing and/or commercial agreement with technical assistance.
