SINT® Engineering Polymers: WAMGROUP’s Composite Materials Strategy

In the field of bulk material handling, where equipment is routinely exposed to abrasion, corrosion, and mechanical stress, materials innovation is often a key factor in improving reliability and sustainability. 

WAMGROUP, a leading global manufacturer of equipment for bulk solids handling & processing, has adopted a forward-looking approach through the in-house development, manufacturing and use of SINT® engineering polymers—composite materials designed to replace traditional metals in a wide range of demanding applications.

Materials Innovation with Purpose

Developed in collaboration with TECNO CM—an affiliate company founded in 1991 specialised in polymer manufacturing—SINT® represents WAMGROUP’s response to the operational and environmental limitations of conventional materials. Engineered for durability, lightness, and resistance to chemical and mechanical wear, SINT® polymers offer a practical alternative to metal components, particularly in systems where high performance and minimum downtime are essential.

These materials are also designed to meet hygiene requirements in sectors such as food and pharmaceuticals, where regulatory compliance is critical.

Cross-Functional Applications

SINT® engineering polymer is used among several WAMGROUP product lines, providing measurable improvements in performance and durability. In the conveying and feeding technology , products such as the SINTSCREW® and micro-batch feeders MBF/MBW incorporate SINT® elements for improved wear resistance, reduced contamination risks, and easier maintenance.

In pneumatic conveying, EXTRABEND™ and EXTRACURVE™ pipe elbows manufactured from SINT® offer reduced wear and lower energy requirements compared to traditional steel pipes—particularly relevant in applications involving abrasive powders.

In mixing equipment, the WETMIX V05 mortar mixer and DUSTFIX Industrial Dust Conditioner utilises a SINT® mixing chamber that is lightweight, non-stick, self-cleaning and easy to handle, making it especially suitable for on-site operations.

Contributing to Environmental Efficiency

The strategic use of SINT® engineering polymers also supports WAMGROUP’s broader sustainability objectives. The material’s extended durability reduces the frequency of component replacements, resulting in less waste and fewer maintenance interventions. Its lighter weight contributes to lower energy consumption in driven systems, while the reduced use of metals helps to limit the overall environmental impact of manufacturing.

As industries move toward more sustainable production practices, the use of long-life, low-impact materials like SINT® becomes increasingly significant—not only from an operational standpoint, but also in terms of regulatory compliance and corporate responsibility.

Looking Ahead

SINT® is now a core element of WAMGROUP’s engineering approach, offering the flexibility to be adapted across a wide range of applications. Its ability to meet technical, hygienic and environmental requirements makes it an increasingly valuable resource in sectors ranging from building & construction to food processing and wastewater treatment.

Rather than a disruptive shift, the integration of SINT® represents a steady evolution in materials use—balancing performance and efficiency. For WAMGROUP, it is both a practical engineering solution and a reflection of a long-term commitment to innovation in component design.
