In the footwear industry, cleaning and degreasing polyurethane (PU) soles represent a critical phase of the production process. An inadequately treated surface can compromise adhesive bonding, reduce the quality of the finished product, and generate costly waste.
For this reason, an increasing number of companies are choosing custom-designed washing and degreasing systems, capable of ensuring consistent, repeatable, and high-performance results.

Challenges in Washing Polyurethane Soles

Polyurethane is widely used for soles due to its lightness and durability, but it presents several challenges, including:

• residues of molding release agents
• oily contamination and surface grease
• complex geometries and dimensional variations
• the need for delicate yet effective treatments

A standard system is often insufficient to manage these variables. Advanced technical design is required, capable of adapting to both the product and the production cycle.

3D Design and Special Systems

Firbimatic operates a technical department specialized in 3D design, supporting customers from the initial concept through to the complete development of the system.
Thanks to three-dimensional modeling and automated analysis of design variants, it is possible to:

• simulate the washing process prior to system construction
• optimize flows, cycle times, and consumption
• identify the most efficient production methods
• design systems perfectly integrable into existing production lines

Each PU sole washing and degreasing system is developed according to the customer’s actual requirements, taking into account production volumes, sole types, and required quality standards.

Tangible Benefits

The adoption of a custom-designed system delivers immediate and measurable advantages:

• improved bonding between sole and upper
• reduced production waste
• greater process repeatability
• increased production efficiency
• optimal control of washing parameters

The result is a more reliable final product and a more competitive production line.
