Using Finite Element Analysis (FEA) in seal design

Finite Element Analysis  provides data to help predict how a product will function under those applied conditions and identifies areas where the design can be optimised and improved, without having to test multiple prototypes. Here we explain how our engineers use FEA to design the optimal sealing solution for our customer applications.

Are all elastomers the same?

Elastomer rubbers look very similar – but are they all the same? With many different base groups and recipe formulations, there’s a huge range of elastomer materials suitable for applications with varying temperature ranges and chemical media compatibility. It’s critical to the seal performance to make the right choice.

The importance of engineering tolerances

Tolerances are present in every man-made item as it’s practically impossible to repeatedly manufacture something to an exact size or specification. When manufacturing seals, it’s important to  understand which tolerances impact performance (and by how much) to ensure that a system is optimized for overall performance, and whole-life product cost.

Elastomer manufacturing moulding processes

How is it manufactured? A question we get asked in the seal design process, but perhaps not considered often enough. How a rubber seal is produced can affect a number of things; the cost, the material choice…even how a part should be designed. All of these can have a significant impact on the performance of … Continued

Polyurethane as a seal material

The foam in your armchair. The strap on your wristwatch. The wheels on a supermarket shopping trolley and beyond; Polyurethane certainly has a diverse range of uses since its invention almost 85 years ago. Aside from day-to-day products; it is also a highly capable and versatile sealing material – and an option that is often overlooked.
