RIGID MOLDING PROCESS

Loctite® brand Resinaid® products are easy to integrate into your existing process. Once a shell investment hasbeen made, the shell molding process utilizing the Loctite® brand Resinaid® Molding Compounds and Loctite®

brand Adhesives begins.

STEP 1

The investment is filled withLoctite® Resinaid® Low ViscosityMolding Compound.

STEP 2

The filled investment is coveredand then placed in the Loctite®

Resinaid® Light Cure System for theinitial cure.

STEP 3

When exposed to light, the outerportion of the shell is formed, creating a uniform wall thicknessof 0.030” throughout the shell.Typical exposure times range from5-20 seconds, depending on thecolor of the molding compound.

STEP 4

The remaining uncured moldingcompound material is removedfrom the investment using theLoctite® Retrieval System.

STEP 5

The uncovered investment is givenits full and final cure in the Loctite®

Resinaid® Curing System. The useof the inert gas option will result ina shell with a tack-free surface andhigh gloss, thus minimizing subse-quent cleaning steps. If the inertgas option is not used, the shellmay require cleaning and buffing inorder to achieve a high gloss finish.

STEP 6

A high viscosity Loctite® Resinaid®

Molding Compound is used toform the vent channel and curedby a Loctite® brand High IntensityLight Source.

STEP 7

The receiver is assembled with aLoctite® brand Light/Moisture CuringAdhesive and then positioned inthe shell. The receiver tube is thenfed through the receiver hole andtacked to the shell with theLight/Moisture Curing Adhesive.

STEP 8

Once the electronics are insertedinto the shell, the face plate is positioned onto the open end ofthe shell and bonded with Loctite®

brand Instant Adhesive or LightCure Adhesive.

STEP 9

A Loctite® brand High Intensity LightSource is used to cure Loctite®

brand Light Cure Adhesives.

STEP 10

Once the receiver tube is cut, theface plate is then trimmed to thecontours of the shell, and theprocess is complete.

SHELL REPAIR PROCESS

Loctite® brand Resinaid® High Viscosity Molding Compounds are the choice for the repair of cracked ordamaged hearing aid shells. Repairs can be accomplished in seconds utilizing the Light Cure MoldingCompounds and Equipment, ensuring that the hearing aid is back in the hands of the user in the shortest time possible.

STEP 1

A cracked shell.

STEP 2

The shell is lightlyabraded in the crackedarea to remove potentialsurface contaminationand prepare the surfacefor the repair process.

STEP 3

A light coating of theappropriate Loctite®

Resinaid® High ViscosityMolding Compound isapplied to the abradedarea.

STEP 4

The Molding Compoundis cured using a Loctite®

brand High Intensity LightSource.

STEP 5

The patched area isbuffed to blend in withthe hearing aid shell.

STEP 6

The repair is completeand the shell is ready forreturn.


R

The Loctite® Resinaid® Curing System is a self contained UV/Visible Light Curing system that is used for the manufacture ofhearing aid shells. The system has been specifically designedto perform in conjunction with Loctite® brand Resinaid® MoldingCompounds. An 8”x 8” curing area allows for the curing of multiple shells at one time. A gas dispersion manifold providesfor a tack-free cure of the Molding Compound. Multiple timersare used to adjust light exposure to the shell(s) and the amountof time in which gas is used during the curing process.

The optional retrieval system allows for the efficient recaptureof uncured Loctite® brand Resinaid® Low Viscosity MoldingCompounds. Four color-coded hand held applicators and storage vessels are provided.

Features

Timed inert gas blanketing option provides fortack-free shell surfaces with minimal gas usage.

Air-cooled surface of curing chamber preventsoverheating of devices.

Multiple timers allow operators to preparehearing aid shells using a variety of Loctite®

brand Resinaid® Molding Compounds withoutresetting individual timers.

Light source is specifically designed for use withLoctite® brand Resinaid® Molding Compounds.

Loctite® Resinaid® Curing System curing area of8”x 8” provides sufficient space for irradiatingmultiple devices simultaneously.
