Application FAQ’s / Lessons Learned

Head Type Rubber is an incompressible solid, it can only be deflected

• Type 1, 3, 4 – Minimal Deflection; Highest Energy Absorption; Application: High Load/Over Slam

• Type 2, 5 – Greater Deflection; Lower Energy Absorption; Application: Low Energy Dynamic Load

• Type 6 – Most Deflection; Lowest Energy Absorption; Application: Low Energy Static Load; Non-linear Compression Curve Characteristic; Ultimate Acoustical Soft Sound and Feel.

Retainer Style• Ergonomics:

– Best: Pull thru – Must have access to back panel

– Better: Push thru – Tool necessary

– Good: Twist in – Line up with tear drop shaped hole in substrate & rotate 360

• Retention:– Best: Twist in – Maximum retainer

ratio & durometer available

– Better: Pull thru – Solid neck & retainer

– Good: Push thru – Hole for installation allows for deflection

• Cost:– Best: Pull thru – Difference in tooling

– Better: Push thru – Addition of core pins in tool cost

– Good: Twist in – Lower cavitations

Substrate Requirements• Metal Substrate:

– Holes punched from installation side yield a beneficial die roll & burr– Holes punched from opposite side yield a detrimental die roll & burr – resulting

in eventual ergonomic issues and poor bumper retention

• Plastic Substrate:– 1/2mm radius should be molded into the hole from installation side– By varying the local substrate thickness at the hole, a wider selection of

existing parts can be attained

• General Substrate:– Some interference in groove height dimension is allowable to broaden the

selection of build to order parts

• Best Retention:– Match hole diameter with groove diameter line-to-line– Groove thickness to substrate thickness, line to line or slightly tight

Installation

• Insertion tools for push-in bumpers should have a diameter slightly smaller than the insertion hole.

• Insertion tools usually have a shoulder, to prevent piercing the carrot.

• If installation is difficult try:• Armada Rubber proprietary molded in lubricant that can

be made in almost any durometer and in any material.• As a last resort try a small amount of Rosewater

NOTE: Many factors affect installation efforts: Operator Attitude; Hole Size; Durometer of the bumper; Proper install tool; Operator’s angle of attack; Shape of hole (burr or die roll); Temperature (ambient and that of the rubber bumper, warmer is better); Humidity; Bloom or Surface Contaminants if any

Recessed Head Bumpers

• These bumpers are specifically designed to receive a fastener.

• If bumper ships with integrated fastener interference fit is necessary.

• For bumpers attached with screws, depending on durometer & torque requirement, a washer may be needed to prevent damage during installation

• Recessed head bumpers are chosen when maximum retention is essential for the application

Hole Plugs

• On plane sealing – this style has a mushroom shaped head that seals on the surface – excellent for off-plane hole distortions

• Radial sealing in the through hole – Diameter interference fit of 1 to 2mm necessary

Valves

• Armada Rubber has highly engineered single shot valve systems capability

• One or two way valves to selectively move water and/or air

• Multi-piece assembly valves protect valve function against mud, stone impingement and other environmental issues

• Applications: Head/tail light vent tubes that inhibit water/dust intrusion; structural foam injection valves; one-way plenum drains; duckbill drains, etc.

Line Plugs

Line plugs require interference between parts for the plug to retain. This interference occurs between the inside diameter of the line and the outside diameter of the plug.

Grommets

• Grommets act as isolators or protect a part that travels through them.

• The dimensions of a grommet must be close to that of the substrate into which it will be installed.

• Grommet Applications are: Isolators, drains, wire/tube pass through.

Grommets

• Grommets are dynamic energy absorbers• For ease of installation a lead-in is recommended• Grommets for mounting applications such as ABS units

mounted to the bracket and vehicle are critical for noise and vibration abatement.

Caps

• Caps can be used to either keep fluid from flowing in or out of an area, they can be used as a bumper or as a stand off.

• Interference between the I.D. and O.D. should be 10 – 15%.

Specialty Parts

• Stabilizer/isolator pockets for brake/fuel line; single piece engineered latch pocket/receiver.

• Dampeners• Vacuum connectors• Gap hider/cosmetic close-out generally molded

in TPO, TPE or Santoprene.

Summary

• Piece Price Reductions exist with Better Technology

• Better technology comes in the form of:– Superior Materials formulated and
