Trelleborg Presents Optimum Sealing Solutions for Beverage Filling Systems at Drinktec

Specifically developed for food and beverage applications, both sealing materials are FDA (Food and Drug Administration), USP (United States Pharmacopeia) Class VI and 3-A Sanitary Standards approved. Ideal for filling and packaging equipment, these Isolast compounds provide outstanding resistance to concentrated flavoring additives, which can cause excess swelling in conventional elastomers. In addition, they withstand frequent harsh CIP (Cleaning In Place) and SIP (Sterilization In Place) regimes, ensuring extended seal life.

Beverage Filling Systems

Martin Krüger, European Sales Manager for food and beverage sealing applications at Trelleborg Sealing Solutions, says: “We supply many standard seals and customer-specific molded parts made from Isolast, such as flange seals for sockets, safety valves or seals for retractable spray nozzles. Thanks to Isolast compounds specifically developed for food and beverage applications, we can provide individual, cost-effective components offering industry-specific performance for demanding filling applications.”

Isolast is suitable for seals and molded parts that are exposed to extreme chemical and thermal conditions. Being almost chemically inert, Isolast is resistant and durable in contact with media including solvents, acids, alkalis or steam and has operating temperatures between -40 °C and +325 °C. This makes Isolast especially suitable for use in foodstuff technology, such as in beverage and milk industry filling systems, where seals in contact with foodstuffs must remain neutral while withstanding cleaning processes that involve hot steam or aggressive media.

Developing Seals “Hand in Hand” with Trelleborg

Drinktec 2017: From prototype design to finished solution; Trelleborg Sealing Solutions provides advice and support to its customers throughout the development of sealing systems and engineered molded parts.

‘Hand-in-Hand Engineering’ is how the sealing specialists at Trelleborg refer to the approach where customers receive advice and support from prototype design to custom solution. Trelleborg will explain how complex sealing systems and custom moldings are produced in five stages. Regardless of whether they are a new development or a rapid prototype to be used as a replacement part, with Hand-in-Hand Engineering, Trelleborg Sealing Solutions offers a one-stop shop for technical support, maturity-level validation and project management throughout the whole development process.


Trelleborg Sealing Solutions is a leading global supplier of seals and moldings, which can be integrated into machinery, equipment and vehicles. From standard solutions such as the renowned O-Ring to complex moldings and system solutions, Trelleborg develops and manufactures seals using proprietary materials. ‘Hand-in-Hand Engineering’, is the process where Trelleborg stands alongside its customers as a partner – from design process through testing to series-production, always as the customer needs it. The five steps in the process – specification, verification, optimization, validation and manufacture – are modular in concept and as a result Trelleborg can become involved in every phase of product development.

Individual design using the right materials

Hand-in-Hand Engineering’ has a part to play in all fields and areas of operation, for example with its custom sealing solutions for the food and beverage processing industry. Specification and requirement profiles come at the beginning of a project: the starting point may be a specification or even just a 3D scan of the installation space available. Design and materials are specified as part of the subsequent verification process. Trelleborg has more than 10,000 varieties of sealing materials, which can be adapted for specific uses. For instance, these include elastomers that are specifically suited to applications in the food industry or solutions compatible with environmentally friendly hydraulic lubricants used in sensitive sealing systems for ships, drilling platforms and offshore wind-farms.

Test phase with simulation and prototype

Before a prototype for a seal or a molding is produced, Trelleborg examine the functions and the stresses using a number of FEA (Finite Element Analysis) simulations. In the next stage, the solution will be optimized in a process that involves numerous tests on prototypes. Thanks to repetitive processes, the solution can be adjusted with a view to its ultimate use. Validation is used to determine the final design and to develop production test tools. The fifth and final stage in ‘Hand-in-Hand Engineering’ is series production, using tools developed by Trelleborg.

Level of maturity consistently in view

Central to Hand-in-Hand Engineering is consistent information flow for everyone involved in a project. Transparency leads to maturity-level validation throughout the whole product development. At any time, project maturity can be assessed using defined parameters. In this way deviations from the required quality levels can be detected at an early stage, in order to avoid defects or errors. Thus customers receive reliable information about when a product attains market maturity, and about the costs of manufacture, at an early stage in development. With ‘Hand-in-Hand Engineering’, customers not only achieve ever quicker product cycles, but also the degree of innovation that the market requires.

A uniform procedure for all industry segments

‘Hand-in-Hand Engineering’ is used in various industries to manage complex tasks for critical applications reliably. Trelleborg will usually provide advice and support to its customers as a development partner from the start, but thanks to the modular structure of the development process, it can get involved in any phase of development. Over the course of weeks or months, custom sealing systems and moldings are produced jointly with the customer.

“As far as the subject of sealing is concerned, many people just think of the classic black O-Ring and standard rubber seals. However, we can immerse ourselves more deeply in our customers’ production development and help with design via Hand-in-Hand Engineering,” says Prof. Dr. Konrad Saur, Director Global R&D for Trelleborg Sealing Solutions. “We can develop a custom and individual seal specifically for critical and complex functional parts –even within a matter of hours in an emergency.”

Showcases for Beverage & Liquid Food Industries at Drinktec 2017

Trelleborg Showcases Sealing Solutions for Beverage and Liquid Food Industries at Drinktec 2017

Trelleborg Sealing Solutions will present solutions for the beverage and liquid food industries to ensure tastes and flavors “remain absolutely pure” at the Drinktec 2017 trade show in Munich, Germany.

The seal developer, manufacturer and supplier will be showcasing its range of sealing systems and materials, which ensure the safe, reliable and hygienic filling and packaging of drinks and dairy products at the event taking place between September 11 and 15.

Visitors to Stand 549 in Hall A3 will get the opportunity to ‘meet the experts’ and learn how Trelleborg employs the principle of hand-in-hand engineering to produce tailor made seals – from initial concept to the final product.

Drinktec 2017

The decisive factor for the filling of alcoholic and non-alcoholic drinks or the packaging of dairy products such as yogurt or cream is that the plant and equipment has safe, reliable and hygienic sealing systems.

At Drinktec 2017, Trelleborg will demonstrate how, with high-quality engineering, it accompanies the customer from initial design via the prototype to a complete solution including custom-delivery if required. The sealing specialist also offers technical advice, ensures product maturity and provides project management, spare parts and plant maintenance – all from a single source.

Carsten Stehle, Managing Director of Trelleborg Sealing Solutions in Germany, said: “For us the beverage, dairy and food industries are key markets in which our sealing solutions can ensure safe and reliable filling and packaging with high standards of hygiene. For our experts, Drinktec is the ideal platform where they can meet decision-makers in these various industries, find out more about their current needs and develop individual solutions to meet these requirements.

At present, the beverage industry is faced with major challenges as far as filling and packaging are concerned. With so much diversity in drink and dairy products currently, different types of beverages have to be filled by a single plant. It is very important that the aromas do not become intermixed – this applies especially to smaller producers, for example micro-breweries which make varieties of craft beer with different flavors, such as fig, grapefruit or coffee.”

Martin Krüger, Area Sales Manager Industrial at Trelleborg Sealing Solutions in Germany, said: “The carryover of flavors is an issue that can arise in a filling plant when different drinks or dairy products pass through the system one after the other. For tastes and flavors to remain absolutely pure, the seals in the plant need to fit perfectly and must meet the highest standards of hygiene. This also means that there mustn’t be any ‘dead space’ in the system where liquids can collect.”

Trelleborg will talk about how it uses Finite Element Analysis (FEA) in order to simulate the behavior of molded parts during installation and in actual usage to improve the function of the seal even before production of the prototype, as well as allowing a number of simulated design options. The technique can also facilitate the early detection of dead space in a plant, so that deposits and possible bacteriological contamination can be avoided – a filling plant with no dead space requires fewer cleaning cycles.

Whether the product is a standard part in ethylene propylene diene monomer rubber (EPDM) or complex molded component made from specialist materials such as Isolast® perfluoroelastomer (FFKM), Trelleborg has design competence for every sealing application encountered in a filling plant.
