ITEM’S TO CONSIDER WHEN SELECTING A POLYMER

1. Chemical compatibility (oils, fuels, etc.)
2. Physical characteristics (harder or softer materials)
3. Environmental exposure (ozone resistance, etc.)
4. Product life expectancy, in the working environment.

BUDGETARY, PROJECT SCHEDULE AND QUALITY CONTROL ISSUES TO CONSIDER

1. The quantity of parts to be produced annually.
2. The number of cavities in the mold or die versus the per-piece cost.
3. Custom parts can be produced in one of our domestic or cost-effective ISO 9000 certified offshore plants.

Our CNC systems accurately dispense a variety of conductive and non-conductive materials.  The RTV (room temperature vulcanization) or UV (Ultraviolet) cured gasket bead naturally adheres directly to the work piece.  Gaskets requiring thin profiles, intricate shapes and / or changes in the Z-axis or elevation are easily dispensed by our robots.

Electrically conductive silver or nickel-graphite filled silicone gaskets can provide high shielding effectiveness while acting as an environmental seal. Monel or aluminum mesh, oriented wire in silicone, metalized fabric over foam and other specialty products are also manufactured and formed into gaskets providing a high level of attenuation.

Our EMI Shielding products can be can be molded, die-cut, extruded or fabricated, depending on the application. Let our professionals help you specify the right product for your needs. Email your CAD drawings to us at so that we can help.

WATER JET

Water jets are able to cut complex shapes and parts in almost any material – from metal of all sorts, to stone, glass, ceramics, rubber and plastics.

Since water jet machines cut parts with no heat-affected zone, secondary finishing is typically unnecessary.

Because water jets put no lateral force and exert very little downward force on parts they are cutting, no elaborate fixturing provisions are required.

Our Dynamic Water jet with Active Tolerance Control produces more accurate parts at significantly higher cutting speeds than parts cut with a conventional water jet.

The Dynamic Water jet cutting system uses a newly-developed advanced motion system that incorporates unique mathematical cutting models, which control a small, articulated wrist that is attached to the cutting head.

The wrist allows the cutting head to tilt in any direction, compensating for the stream lag and taper experienced with conventional water jet cutting machines.

1. Cut parts 25-400% faster than conventional flat stock waterjet cutting machines.
2. Improve cut part tolerances and geometry at significantly higher cutting speeds.
3. Virtually eliminates taper; taper is less than 1 degree in
   straight-line geometry.
4. Reduce part cost without hard tooling.
5. True part stacking ability with consistent tolerance layer to layer.
6. No secondary finishing required.
7. Cuts metal, stone, glass, rubber, plastic and composites.
8. Make parts from a variety of CAD files.
9. Can cut to tolerances of +/-.003 or better, depending on the material.

WRS can supply CAD services.

DESCRIPTION

Fiberglass reinforced silicone sheeting is typically used for gaskets or seals requiring a resilient, non porous sheet material suitable for operating temperatures from -100 to 500F but is not limited to such applications.

The material is resistant to deterioration by weathering and engine oil and remains flexible over the temperature range noted. Fiberglass reinforced silicone sheet is available in many different thicknesses.

The fiberglass is centered between the 2 layers of silicone that gives the material dimensional stability and higher tensile strength.

FEATURES

Excellent Gasketing Material
Extreme High & Low Temperature Resistant
UV / Ozone Resistant
Non- Toxic, Chemically Inert
All FDA approved Ingredients
Low Compression Set
Fungus Resistant

SPECIFICATIONS

VITON COATED MOUNTS

Our coatings our chemically bonded to rubber components providing a variety of enhancements including chemical and ozone resistance and in certain cases, clean room compatibility.  Since our coatings chemically bond to the rubber, they will compress, elongate and deform in unison with the rubber component.

ADVANTAGES

1. Coatings encapsulates the mount, which provides a broad range of chemical and heat resistance.
2. Can have a wider temperature range and tolerance than an uncoated product.
3. Can successfully handle thermal cycling, flexing and vibration.
4. Rate as “Excellent” to “Outstanding” against everything from heat aging to oxidation resistance.
5. Finished coats can be specified to be tough, flexible, and resilient.
6. Will not crack, peel or delaminate due to any of the above conditions.
7. Can be easily repaired by cleaning the damaged surface and applying the coating over the affected area including the previously coated surface.
8. May offer corrosion protection lasting up to 2 to 10 times longer than other mere paints.
9. Very low out gassing makes our Viton^® encapsulated mounts perfect for clean room applications!
10. Comes in standard or fluoropolymer-enhanced versions.
