Rubber-to-metal buffers are among the most common applications for elastomers. They are used whenever machinery or equipment needs to be protected from vibrations and shocks. Although they seem simple, their design is complex because there are a lot of influencing factors to consider.<\/p>

Here are five facts about rubber-to-metal elements that companies should keep in mind.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

1. Strictly speaking, rubber-metal elements have three components<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Rubber and metal do not easily form a permanent bond. While it is possible to create a direct bond through process control and compatibility of the two components, this requires considerable effort and know-how. Companies typically use an adhesion promoter that serves as a chemical bridge and improves the adhesion properties of both elements. Strictly speaking, rubber-metal elements therefore consist not of two but of three elements: Elastomer, metal<\/strong> and adhesion promoter<\/strong>.<\/p>

It is important that the adhesion promoter also receives attention during production. If it is damaged or compromised, there is a risk that the bond between the rubber and metal will be impaired.<\/p>

For example, the adhesion promoter can be damaged if it is exposed to high temperatures for too long. However, injection molds are pre-tempered to speed up the vulcanization process. Therefore, it is important to reduce the exposure and molding times of rubber-to-metal elements. In this way, you avoid damage to the adhesion promoter.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

2. The project requirements also apply to individual components of a rubber-metal element<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Rubber-metal elements consist of different groups of materials that are chemically bonded together. Unlike composite materials, however, the materials retain their individual characteristics after vulcanization. This fact should also be taken into account in design and material selection<\/a>. All components must meet the project requirements<\/strong>, otherwise the combined element is not suitable for the intended application.<\/p>

For example, both the elastomer and the metal must have the right (shore) hardness or grade to meet the expected load. The same applies to resistances. If the element is intended for outdoor use, for example, all components must be optimized for outdoor use to the extent possible. The metal, for example, should have a corrosion coating suitable for the intended use, and the elastomer should have appropriate properties in its compound composition.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

3. The geometry of the overall system is decisive<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

If rubber-metal elements are to carry large loads, for example, in addition to the component geometry, the weight distribution<\/strong> \/ center of gravity of the system is also of great importance. This is the case, for example, with machine feet. In addition to the component geometry and hardness, which are decisive for the stiffness of the bearing, the installation situation of the bearings and the geometry of the machine also play an important role in terms of static load and dynamic performance. If the center of gravity is exactly in the middle, all pedestals are equally loaded. However, if the machine is designed asymmetrically, the load is distributed unevenly. As a result, individual machine feet are exposed to higher static and dynamic loads than others. If this circumstance is not taken into account in the design and layout of the bearings, these components can fail in use after a short period of operation, which can cause further damage to the machine.<\/p>

Therefore, certain input variables should be considered when designing rubber-to-metal elements.
The static load distribution, as well as further parameters (e.g. frequencies, amplitudes, etc.), are important input variables, because the overall performance depends on them, provided that the component is designed correctly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
