Form in place (FIP)

Untitled 1 4

Parker Chomerics’ Cho-form (Conductive) and ParPHorm (non-conductive) are two types of form-in-place gasketing materials that are used in a variety of industries, including electronics, automotive, and aerospace. These materials are able to conform to complex shapes and create a watertight seal, making them ideal for applications where traditional gaskets cannot be used.

HITEK Electronic Materials offers a form-in-place gasketing service that uses Cho-form and ParPHorm to create custom gaskets for a wide range of applications. Our team of experienced technicians can work with you to design and manufacture a gasket that meets your specific needs.

Design Considerations

Typically we recommend a minimum gasket height of 0.8mm or 1mm with a maximum of roughly 1.6mm for a singular bead. Higher would be possible with bead on bead.

To achieve a good quality gasket, we recommend about 0.2-0.3mm space within the metal chassis, to allow for the bead to sit nicely within the groove.

It is preferred for the metal work receiving the gasket has a U-shaped groove as it may offer more longevity of the gasket bead. While we can dispense/ facilitate a FIP Gasket on no groove metal work/ etched metals we cannot assure the same level of longevity.

Benefits of FIP

  • Custom design – Our programmable machine allows for the production of gaskets in various shapes.
  • Watertight seal – Cho-form and ParPHorm create a watertight seal that prevents leaks.
  • Conformable – Cho-form and ParPHorm can conform to complex shapes, making them ideal for applications where traditional gaskets may not suffice.
  • Durable – Cho-form and ParPHorm are durable materials that can withstand harsh environments.
