Environmental Sealing Form-in-Place Kemtron Form-in-Place (FIP) Elastomer compounds are directly dispensed onto component hardware or enclosure via a pressurised fluid dispensing system on a numerically controlled XYZ table to form a gasket for dust and moisture sealing. The dispensing machine deposits the gasket by following a pre-determined CNC path to provide accuracy and repeatability. The process advantages are: • Component provides an integrated environmental gasket. • Assembly time is reduced as gasket is included on component. • Rapid prototyping. • Low setup costs. • Smaller gasket land required. • No material waste. • Can be applied to metal and plastic components. Applications Suited to applications where small, intricate gasket profiles are required, such as on multi-compartment labyrinth housings with minimum gasket land area where traditional larger types of gasket are not suitable. This process also negates the assembly costs associated with traditional gaskets as the Form-in-Place gasket becomes an integral part of the housing or enclosure. The process is suitable for depositing on both metal and metallised plastic components/housing. Availability Kemtron can dispense FIP gaskets directly onto the customer's free issue hardware or can procure the component hardware thereby reducing the customer's supply base. Design Considerations • The gasket height can be specified between 0.4mm to 2.0mm, gasket width will typically be 1.5x the gasket height. • Recommended gasket compression is between 20% and 30%. Over-compression can damage the gasket and as compression stops cannot be incorporated into the gasket they should be designed into the component hardware. • Gasket path for the deposition can be determined from a sample part, drawings or CAD files. Production Capability To meet the varying demands of customer requirements Kemtron has developed its own CNC Form-in-Place dispenser. FIP gasketing work has become a regular feature of our production work and we are able to provide a reliable, accurate and quick response to even high volume orders. Kemtron has a large range of compounds suitable for many climatic conditions. Wide temperature range, chemical resistance & fire retardant grades. 19-21 Finch Drive, Springwood Industrial Estate, Braintree, Essex CM7 2SF, United Kingdom.
