De Beer can produce the flat seals as shown on the drawing from one piece on its CNC cutting machines. But runs of several million pieces are produced efficiently.
Seals may also be attached to hard plastic parts by means of 2-component injection moulding. This saves an assembly step, or seals are made possible in places where no separate seal is possible.
Seals are often small, but crucial components of a product or system. Sealing extremely diverse applications is a challenge every time that requires understanding the science behind the sealing technique. De Beer applies sealing theory and material knowledge in developing solutions for customers.
