Polymeric seals are essential components in almost every industrial and mechanical process enabling the effective containment and movement of liquids and gases under extremes of environment. Friction is intrinsically related to seal performance. High friction accelerates wear of the seal leading to leakage and/or premature failure, and increases the energy consumption of industrial processes.

Surface (micro-) texturing is a proven technique for reducing friction across lubricated rigid materials such as metal and ceramic materials. Within recent years this technique has been applied and demonstrated for polymeric and elastomeric materials at laboratory level. The project will develop and demonstrate a novel methodology for the design and high volume manufacture of surface textured polymeric components tailored to the (friction) environment within which the component operates, achieving a friction reduction of >20% at a cost premium of <10%.

The novel methodology combines:

  • advanced modelling software for the identification of surface texture patterns that lead to significant friction reduction for target rubber and plastic seals and applications
  • software for the design of mould tools that enable the reliable transfer of texture patterns onto the seal surface
  • novel automated laser system for the application of hierarchical laser induced micro- texture patterns to the mould tool surface
  • best practice for moulding and de-moulding using surface textured moulds
  • inline optical inspection for surface texture pattern quality control

The project will establish three pilot lines for demonstration of:

1) mould tool design and manufacture;

and the design and manufacture of

2) rotary seals for engine applications; and

3) reciprocating seals for industrial processes.
