Cut Seals

10-1 DESCRIPTION Cut gaskets are produced using a die cutting machine or a numerically controlled machine driving a cutting tool (oscillating or not). We cut the seals in our standard plate formats and in all rubber grades described in Chapter 1-1 with a thickness tolerance of 1.0mm and very accurate physicochemical characteristics. When the goal is to reduce costs, and that the thickness tolerance and material performance are low, rolls of calendared rubbers are more suitable. 10-2 ADVANTAGES The molding of sheets and disks gives greater constancy of thickness with tolerances more accurate than those made from big sheets or rolls. To ensure traceability, all our blocks have a molded tab giving information such as : - the grade - the batch number - the thickness - the date of vulcanization 10-3 DIMENSIONS There is almost no limit to the shapes of such seals. We offer stamped seals in accordance with your samples or drawings, or sheets for customers wishing to manufacture their own gaskets. Thickness of the standard formats : From 0.2 to 50mm in 300 x 300mm From 0.8 to 50mm in 500 x 500mm From 4 to 30mm in 600 x 600mm From 1 to 15mm in 800 x 800mm (according to the material) All thicknesses cannot be produced in all qualities (contact us) 10-4 OPTIONS Fabric insertion : It is usually Nylon® fabric from 0.1mm to 0.5mm with 1 or 2 folds depending on the thickness or 1 fold on each surface. It is also possible to use other types of fabric ( contact us). The fabric insertion improves the mechanical properties of the gaskets, such as the creep strength. Adhering of PTFE The bonding of elastomer to a PTFE sheet makes it possible to obtain a part having, on one side, the chemical inertness of the PTFE, and on the other side, the flexibility of the elastomer.

10-5 FIBRE GASKETS - GRAPHITE- RUBBER/CORK GASKETS Stacem works with the company REINZ for the cutting of sealing elements of elastomer fiber materials, graphite, rubber cork... During the installation, the validation of the tightening can be confirmed by Fuji Films, plastic film incorporating color capsules breaking under the effect of pressure. According to the series and/or the material, the integration of an internal metal insert can be achieved, improving thereby the mechanical characteristics of the gaskets to creep. - AFM The AFM products offer a wide range of materials based on...

- Carbon fiber material : AFM 44 AFM 44 has a very good temperature resistance together with high mechanical strength, as shown by its high values for residual stress and tensile strength. Standard size of the sheets 1500 x 1500 mm, also available in 1500X4500 mm.
