Those pin tips are made mainly of rubber and have a protective thrust pad attached to the working surface that can be formed by different materials.
The moldable backing material has the ability to change from a fluid to a solid and back to a fluid again.
When material is in a liquid phase, the reconfigurable pin is immersed to the required depth.
