How Amorim Cork Solutions is Reinventing Materials Innovation Through the iCork Factory

As railway networks evolve to meet the demands of higher capacity, stricter environmental requirements, and tighter maintenance cycles, material engineering has become a decisive factor in track performance. Amorim Cork Solutions, an established leader in cork-rubber technology for rail applications, continues to expand its capabilities with the iCork Factory, a dedicated innovation hub designed to accelerate the development of next-generation elastomeric solutions for global rail infrastructure.

The iCork Factory operates as an incubator of material innovation, formulation development, and precision manufacturing. Within this facility, engineers can develop new cork–rubber formulations (that can incorporate natural/recycled rubber, or circular-economy materials such as EVA), material behavior, and engineer composites optimized for vibration mitigation, acoustic insulation and durability.

Flexible Production Capabilities for Tailored Vibration-Control Components

One of the strongest differentiators of Amorim Cork Solutions is the versatility of its manufacturing capabilities. The production process supports a wide range of component types: sheets or rolls, blocks or cylinders, and “cured-to-thickness” components, meaning final parts are delivered in the exact thickness and geometry required by the client, including fully customized parts with complex shapes, enabled by advanced CNC machining and waterjet cutting technologies. This flexibility allows the company to meet the demanding specifications of railway infrastructure projects without compromising dimensional accuracy, long-term durability or mechanical and acoustic performance.

Extrusion technologies, pellet-based feeding, and continuous press lines afford scalability, making the company capable of fulfilling large-volume orders for major infrastructure projects. In addition, our global industrial infrastructure guarantees uninterrupted supply for major projects.

Moreover, components can be produced either in flat form or with profiled surfaces, the latter enhancing acoustic attenuation and overall vibration-control performance. All products are certified in accordance with the most demanding industry requirements, ensuring compliance, safety and robust performance.

Complete Product Range for Vibration and Acoustic Control

Amorim Cork Solutions offers a broad portfolio of elastomeric components designed for multiple rail infrastructure applications, including but not limited to:

• Rail pads and baseplate pads for direct-fixation systems
• Under-ballast mats (UBM) and under-sleeper pads (USP)
• Floating slab mats (FSM) for slab-track or slab-on-ballast systems
• Special solutions for embedded-rail systems using granulated cork

These products are meant to provide effective load distribution, vibration damping, acoustic insulation, and long-term structural resilience, contributing directly to ride comfort, reduced maintenance needs, and lower environmental impact, all essential criteria for modern railway design.

Technical Support: From Calculation Tools to Full Project Assistance

Beyond materials and manufacturing, Amorim offers technical support and project assistance. Their in-house calculation tools, more specifically the Track Design Assistant (TDA), allow engineers to calculate the mechanical and acoustic behavior of cork–rubber components under realistic track loading conditions. This ensures that stiffness classes, damping performance, and lifecycle durability are tailored to the demands of each specific rail project.

Complementing this, experienced commercial and technical teams provide personalized support, from initial concept and specification through to delivery, installation guidance, and follow-up. Custom formats, private-label options, and design flexibility make Amorim a full-service partner rather than simply a supplier.

Global Manufacturing and Supply Capacity

With production facilities located in Portugal and the United States, Amorim Cork Solutions combines the benefits of local manufacturing with global reach. This dual-location strategy supports efficient logistics, shorter lead times, and reliable supply for large-scale infrastructure projects across different continents.

Delivering Sustainable, High-Performance Solutions for Modern Rail Systems

In a rail industry increasingly focused on sustainability, lifecycle cost, comfort, and community impact, cork–rubber composites offer a unique combination of eco-friendly materials, acoustic and vibration control, and long-term resilience.

Through innovation capabilities, flexible manufacturing, broad product range and engineering support, Amorim Cork Solutions is ready to deliver tailor-made solutions that meet the demanding technical and environmental requirements of modern rail infrastructure, whatever the project’s scale or complexity.
