Controlling Surface Condition in FIPG Application
Increasingly, FIPG processes are replacing traditional gaskets for a variety of automotive applications such as air filters, oil filters, door panels, and external engine parts. The advantages include cheaper material cost, higher throughput capability, ability for assembly at the supplier, and greater control over sealing processes. These advantages, however, come with processing challenges that the manufacturer must take into account; namely the surface of the part they are sealing.
Within the automotive industry, a common FIPG application is RTV (room-temperature-vulcanization). Defining and controlling surface condition prior to applying an RTV silicone sealant is critical for a successful seal. Variables such as inadequate cleaning, over-used washing fluid, excess oil contamination, and poor handling can wreak havoc on an RTV application process. This can lead to rework, customer complaints, and warranty claims after the customer purchases the product. So how does an OEM or supplier design and control an appropriate FIPG process that will be successful?
