AL Gummi + Kunststofftechnik - Sealing Sleeves Silicone

Silicone components for low-dust filling and for decoupling scales when handling dusty bulk materials

High-quality sleeves can be used in many ways in our everyday technical work. No matter which media, we offer you the right solution with the right component for every application. And if there is not yet a component for your specific application, we will develop one for you.

Reproducible product quality and clean workplaces are very important in many industrial filling and weighing processes. Especially when handling dusty bulk materials, individual components play a decisive role.

Many so-called compensators do not fit precisely, are too stiff or even leak. This then leads to safety-relevant risks, especially in the case of substances that are hazardous to health, to which attention should definitely be paid. Our sleeves and compensators made of silicone, on the other hand, ensure dust-tight filling in flexible pipe systems.

Furthermore, it is important for the weighing process that the individual components decouple vibrations and connect different tube diameters in a dust-tight manner. We supply a variety of different silicone components for this purpose.

One of the many flexible connections offered by AL Gummi und Kunststofftechnik is the silicone cradle collar, cradle bellows, vase compensator or step bellows. These components are vulcanized into shape and are therefore completely seamless, which increases both the flexibility and the strength that the connection can withstand.

Our silicone sleeves meet the highest requirements. They are basically FDA-certified, and may therefore also be used in accordance with the strict safety requirements in the food industry, for example.

Due to their extreme flexibility, our weighing collars generate only a very low reaction force, so that they do not influence the weighing. They are very resistant to chemicals, high temperatures and aging.

In addition, we offer a wide range of silicone molded parts – fast, high-quality and inexpensive. From design consulting and toolmaking to prototyping, sampling and process qualification, we are happy to put our many years of experience at your disposal. Our specialty is the production of small batches, quickly and precisely according to your design drawing.

Weighing cuffs and weighing bellows

Another flexible connection is the cradle cuff. These collars are manufactured using compression molding and are therefore completely seamless, which increases flexibility and also resilience. The cradle collar is suitable for a variety of uses, such as the flexible connection of inlet and outlet lines to containers of load cells, mixers, dosing devices or similar devices.

Our weighing collars are made of silicone as standard and are basically FDA-compliant, so they can also be used in the food industry, medical technology or pharmaceutical industry.

Due to their extreme flexibility, weighing collars generate only a very low reaction force, so that they do not influence the weighing. They are very resistant to chemicals, high temperatures and aging.

Other rubber qualities (wear-resistant, antistatic, oil-resistant, heat-resistant, chemically resistant) are possible at any time and on request.

Stepped bellows made of silicone

The silicone seamless stepped bellows allows flexible connection of vessels to load cells, mixers or feeders, with inlets and outlets or other forms of air or powder transport with two different pipe diameters.
When connecting two different pipe diameters, it may be desirable to install a stepped bellows or a conical collar.

Our step bellows are made of silicone as standard and are basically FDA-compliant, so they can also be used in the food industry, medical technology or pharmaceutical industry.

Scale compensator for scale decoupling

The scale or vase compensator is designed for the safe decoupling of filling scales. It prevents deposits in the compensator due to its special shape with seamless and smooth inner walls.

Force-fit connections of components often lead to falsification of weighing results. The special design of the vase compensator compensates for frictional connections and guarantees an unadulterated result.

Often, compensators are not suitable for use in the pharmaceutical sector due to their shape. Product deposits in dead spaces contradict the high demands of the pharmaceutical and medical technology industry. This is because the product residue in the dead spaces often cannot be completely removed even when the component is thoroughly cleaned. In such cases, so-called cross-contamination of batches often occurs.

The vase compensator, on the other hand, consists of a seamlessly molded individual part and is the perfect application due to its special shape. Its special geometry prevents product deposits and is easy to clean, so that contamination of your products is excluded.
