Warranty Reliability and a long service life are synonymous with the Formech brand. However, as with any machinery, certain parts will require periodic replacement and regular maintenance and care will prolong machinery life. Clamp seals The silicone seals applied to the mould table and to the top aperture of the machine (clamp) are seen as being consumable parts, their service life will depend on how the machine is treated and how often it is used.
