Seals in semiconductor equipment work where contamination is the enemy and downtime is measured in wafers. Aggressive plasma, etch chemistries, thermal cycling, and vacuum all attack the material while the seal itself must generate minimal particles and hold dimensional stability through every process cycle.

We specialise in moulding FFKM, the elastomer family this industry depends on and the hardest to process well. Long cure cycles, unforgiving flow behaviour, and expensive material with no tolerance for scrap our depth in this material is the capability, and it extends to large chamber seals moulded in one piece up to 1500 mm.
