Form-in-place (FIP) gaskets are your answer for airtight, accurate sealing for intricate parts. KRA Fab offers FIP gaskets that provide outstanding adhesion, greatly outperforming traditional pressure sensitive adhesive applications.
Conductive form-in-place gasketing further offers a versatile solution to EMI shielding. At KRA Fab, we are fully equipped to provide electrically conductive gaskets accurately located on a variety of shield materials.
The many benefits of our FIP gaskets include:
- Minimal waste of material
- Custom prototyping
- Efficient and accurate application of complex substrates
- Wide assortment of materials to select from
- Extremely fast lead time process
- Ideal for mobile electronics, HVAC, automotive, window, lighting, and electrical purposes
Form-in-place gaskets have been used for industrial sealing applications to replace typical molded or cut gaskets for decades. The FIP process corrects for uneven surfaces and allows greater space for the overall packaging design.
These FIP gaskets replace tape, epoxies, RTV sealants and PSA die-cut gaskets. With cure-on-demand technology, you can skip the necessity of ovens or racks, and eradicate waste due to poorly-fit die-cut gaskets.
Conformation to complex designs on surfaces across three axes is possible, creating an impermeable barrier to air, dust, liquid, or dirt. This makes an unparalleled solution for moisture protection, air sealing, sound dampening, chemical protection or vibration dampening,
Advanced materials science has further answered the need for FIP to seal and protect electronic devices from EMI (Electromagnetic Interference) or RFI (Radio Frequency Interference). By applying dispensed gaskets that utilize an elastomer filled with electrically conductive particles, protection is achieved on every level.
KRA Fab offers a variety of elastomers that provide compliant, resilient seals with conductive particles that deliver advanced shielding performance.

Our form-in-place gasket is completed using automated equipment, ensuring that we will match the exact requirements of your assemblies.
The CNC controlled movement of the KRA Fab application equipment accurately places the gasket material on the substrate.
Placement of the gasket is done by multiple-axes robotic dispensing, driven by a CAD drawing of the part. This process ensures top-shelf adhesion and reliable sealing against environmental variables. This application method also allows us to meet varying height requirements and compensate for uneven surfaces in molded parts and castings to provide consistent, highly reliable seals.
There are several combinations of elastomers and particles that provide a range of desired properties including, compression force, deflection range, electrical conductivity, shielding effectiveness, galvanic corrosion resistance, adhesion and cure options.
Through this process, small seals can be accurately placed in complex patterns to meet the increasing demands of electronic enclosure designs.
These durable, highly conductive seals and gaskets offer years of effective mechanical performance and EMI shielding. The dispensed bead is thixotropic and will hold a predictable shape in the Z-axis known as the profile.
This process also allows for:
high volume production
Design revisions can be easily implemented if necessary. Combining auto-surface-following with a CNC-guided design allows the automation to create consistency in high-volume production while maintaining incomparable sealing.
Many electronic devices are subjected to a variety of environmental conditions. KRA Fab’s form-in-place gasket service is designed to protect electronic devices from harsh environmental elements and EMI/RFI interference.
There are numerous possibilities of EMI Shielding using KRA Fab’s FIP. Our innovative machines are pinpoint accurate enabling us to dispense elastomers on even the smallest designs. Our robotic dispensing system will precisely place an electrically conductive elastomer on contours.
Protection is key.
Through our latest generation form-in-place gasket application, metal, plastic, and glass surfaces and enclosures are sealed against moisture, air, dust, liquids, gaseous substances, dirt and EMI/RFI interference. By implementing in-line curing of the gaskets, production times are cut and turnarounds are increased.
