What is Ascender?

The machine

The Ascender machine features a compact, modular setup that offers tanneries the flexibility to choose between standalone or in-line production.

The machine is available in three different formats to meet the diverse needs of various industries. The available versions are working width 1800 mm, 2600 mm e 3200 mm.

Barnini, IM and Stahl have jointly developed chemistry and mechanics to advance the next generation of leather processing. This new technology enables tanneries to enhance their leather articles and allows for the transformation of lower-quality hides into valuable finished goods, thereby promoting sustainability within the leather industry.

The chemistry

A distinctive portfolio was crafted and tailored for this specific application, utilizing top-tier high-performance solutions to guarantee superior leather quality. Solvent-free, amine-free, and low in VOCs, and meeting the stringent requirements of ZDHC MRSL, Version 3.1, Level 3.

Stahl’s chemical solutions are recommended to get the excellency of the Ascender system.

Perfect for high-quality leather goods ranging from shoes to automotive applications, these compounds enhance leather with superior aesthetic properties and durability. While the Ascender machine can operate without these suggested chemicals, we strongly advise using both elements together to achieve the best results and maintain guarantees.

Why was Ascender created?

From luxury goods to automotive applications, today’s consumers expect leather to excel in touch, aesthetics, and durability. In this competitive industry, leather manufacturers are constantly seeking ways to improve efficiency. Additionally, tanneries face increasing pressure from both regulators and consumers to reduce their environmental impact and transition to more sustainable processes.

Given these trends, the stage is set for a revolution in leather upgrading and finishing. Leveraging Stahl’s core expertise in chemistry and specialized experience in the leather sector, we facilitate significant improvements in finishing processes. This not only adds value for customers and meets consumer demands but also contributes to a reduced environmental footprint.
