LSR and HTV silicone injection moulding for components used in the food and beverage industry.
Silicone: a strategic material for the food industry
In the Food & Beverage industry, material selection plays a key role in ensuring high performance, long-term reliability and safety in the intended applications. Components used in packaging systems, automated machinery and professional equipment must withstand demanding operating conditions while maintaining their functional properties over time.
In this context, silicone is a particularly attractive engineering material thanks to its temperature resistance, elasticity, long-term stability and suitability for manufacturing complex geometries through precision moulding processes.
Silikoneurope specialises in the design and manufacture of LSR (Liquid Silicone Rubber) and HTV (High Temperature Vulcanizing) silicone components, developed to meet the technical requirements of manufacturers of systems, machinery and equipment for the food industry.
The advantages of silicone in Food & Beverage applications
- Resistance to high and low temperatures
Silicone maintains important functional properties across a wide temperature range. Depending on the compound selected, it can be used in applications requiring resistance to temperatures typically ranging from -40°C to +200°C, helping components perform reliably under operating conditions.
- Elasticity and long-term reliability
Silicone’s elastic properties make it suitable for seals, gaskets and flexible components. Selecting the right material helps ensure that components maintain appropriate functional performance, even when subjected to repeated mechanical stress.
- Non-stick properties and ease of use
Silicone’s surface characteristics can facilitate product release and reduce residue adhesion in specific applications. These properties are valuable when designing components for processing, dosing and packaging equipment.
- Precision and design flexibility
Injection moulding makes it possible to manufacture components with complex geometries, functional details and controlled dimensions. LSR is particularly suitable for automated, repeatable production processes, while HTV offers additional possibilities for solid silicone rubber components, depending on project requirements.
LSR and HTV: two technologies, multiple possibilities
Understanding the different types of silicone makes it possible to identify the most suitable solution for each component and its operating conditions.
- LSR – Liquid Silicone Rubber: a liquid silicone material suitable for highly automated injection moulding processes, precision components and complex geometries. It is particularly advantageous when production repeatability and consistent quality are essential.
- HTV – High Temperature Vulcanizing: a solid silicone rubber material cured at high temperatures, suitable for a wide range of industrial applications requiring elasticity, thermal resistance and specific mechanical properties.
The choice between LSR and HTV depends on several factors, including component geometry, tolerances, mechanical properties, operating temperatures, production volumes and compliance requirements. Evaluating these aspects together helps identify the most appropriate solution for each customer’s needs.
From mould design to the finished component
The quality of a silicone component is determined long before mass production begins. Component and mould design, compound selection and process parameter definition are all essential steps in achieving reliable, repeatable results.
Drawing on its expertise in silicone moulding and mould design and manufacturing, Silikoneurope supports customers throughout the development process: from technical requirements analysis and production process definition to component validation.
This integrated approach combines material expertise, engineering design and process technology to address complex application requirements, with a strong focus on quality, dimensional accuracy and production efficiency.
Food contact safety and regulatory compliance
For Food & Beverage applications, silicone selection must take into account the component’s intended use and the applicable regulatory requirements.
Food contact compliance does not depend solely on the material itself. It also depends on the formulation, the conditions of use and the characteristics of the finished article. Each project must therefore be assessed against the regulations applicable to the target market and the specific conditions of contact with food.
Silikoneurope develops components for the food industry by considering the technical and regulatory requirements of each application, with particular attention to compound selection and manufacturing process quality.
Silikoneurope: technical expertise for the Food & Beverage industry
Every application has its own specific requirements. The ability to combine material knowledge, mould engineering and moulding technology is therefore essential to turning technical requirements into reliable, functional components.
Silikoneurope has also conducted joint tests with customers to verify and confirm the suitability of silicone materials, particularly LSR for dairy applications, and is able to provide customer support in this regard.
With its specialisation in LSR and HTV silicone injection moulding, Silikoneurope supports the development of solutions for packaging, containers, automated systems, and industrial and professional equipment used in the Food & Beverage industry.
