Marian die-cuts custom gaskets and seals utilizing a range of cutting techniques such as rotary die cutting, flatbed die cutting, and laser /waterjet/ plotter cutting. The manufacturing technique is chosen based on the application, material, and volume. Marian meets and often exceeds dimensional tolerances, even with complex geometries or very small gasket sizes.
Die-cut Custom Gasket Options
Die-cut Gasket Examples
Camera Lens Gasket
ID / OD Foam Washers
These ID / OD foam washers are manufactured in extremely high volumes. They are made with EPDM foam, used often for noise reduction, vibration damping, and moisture sealing.
Light Shielding Gaskets
These gaskets offer light blocking and cushioning properties for electronic faceplate displays with an intricate design of buttons and switches. Rogers Poron® Foam material was chosen due to its soft and slow rebound properties.
Gaskets and Seals Prevent Leaks
The purpose of a gasket is to fill the space between 2 mating surfaces, generally preventing leakage while the material is under compression. Many products and applications require sealing from different elements: air, water, dust, fluid gas, electromagnetic interference, radio frequencies and even light. In addition to preventing leaks and sealing, gaskets can also serve other functions, for example: cushioning, vibration and noise reduction (washers).
