• Injection moulding machines with large clamping areas and corresponding injection volumes

Rubber-to-Substrate Bonding

Components made by bonding different materials are used across all industry sectors. They combine the uniquely positive properties of the respective materials to create specific functionalities. For instance, rubber-to-metal elements feature the elasticity of rubber while simultaneously providing the structural strength of metal. We can realise a wide variety of material combinations.

• Material combination: rubber-to-rubber
• Material combination: rubber-to-metal
• Material combination: rubber-to-fabric
• Material combination: rubber-to-thermoplastics

Bonding Types

Where bond strength requirements are low, mechanical interlocking partial joints are sufficient. In contrast, incompatible materials and components with high specifications require the application of primers to the metal or fabric, alongside chemical bonding agents, to achieve high-strength adhesive bonds. For rubber and plastic combinations, direct bonding is the ideal method.

• Mechanical interlocking joints for components with low requirements
• High-strength adhesive bonding through the use of primers and bonding agents
• Direct bonding with compatible materials

Metals & Preparation

Iron, steel, aluminium, brass, bronze, and copper are used as structural reinforcements. For a durable bond, the proper pretreatment of the metal parts is of paramount importance. To remove the existing oxide layer and increase the surface area, we blast and degrease the metals before applying primers and chemical bonding agents. This process also provides the required corrosion protection.

• Various metals are used for bonded components
• Tailored chemical bonding agents are used depending on the specific rubber compound

Mould Concepts & Toolmaking

Exact drawings and 3D CAD solid models usually form the basis for a coordinated and coherent concept for highly capital-intensive metal vulcanisation moulds. The design, size and number of cavities of the moulds are largely determined by the component geometry, the compound used, the manufacturing process and the targeted lifespan of the component.
