H2OLock-IMD Injection Molded Desiccants

Description

AGM’s H2OLock-IMD injection molded desiccant is made from a combination of 4A molecular sieve, nylon binder, and various other proprietary additives. As a result, the desiccant material is highly moldable, enabling the final product to conform to customer specified sizes, shapes and thicknesses. This combination of materials delivers optimized adsorption, strength, and form capabilities to best meet customer needs.

AGM’s custom molded desiccant can serve as a replacement for similar products sold through other manufacturers and distributors.

Key Features Include:

Adsorption Rate

*Adsorption rate is affected by part geometry.

Why Use AGM Custom Molded Desiccants?

The benefit to using molded desiccants is found in their form factor and size. The desiccant is shaped using injection molding techniques and the material combination is such that the resulting desiccants are shaped to fit customer specifications, are strong enough for use as structural components in the design, and may be formed very small or to fit complex geometries.

Furthermore, due to the combination of materials employed in their manufacture, AGM’s molded desiccants provide an optimized moisture adsorption rate and capacity, while still delivering customer specific shaping options and crush strength.

4A molecular sieve is a high performance desiccant capable of delivering high capacity even at very low humidity. In addition, nylon is naturally hygroscopic, which serves to compliment the adsorptive capabilities of the molecular sieve and thus promote a high adsorptive capacity. Furthermore, nylon's high strength lends itself well to creating varying shapes and forms.

Is H2OLock-IMD Non-Dusting?

Yes, AGM H2OLock-IMD molded desiccant is non-dusting and exceeds the Type II desiccant dusting requirements outlined in MIL-D-3464E. As such, H2OLock-IMD may be used safely and without concern throughout an install. This enables H2OLock-IMD’s use in electronics and many other areas.

H2OLock-IMD Rapid Prototyping

AGM Container Controls can produce prototype H2OLock-IMD injection molded desiccant parts using 3D-printed molds and benchtop injection molding equipment. This rapid prototyping capability allows customers to evaluate custom molded H2OLock-IMD parts without the upfront cost and lead time associated with production injection molding tooling.

Prototype parts can support application development, material evaluation, and preliminary fit and form testing before committing to production tooling. Because this process uses 3D-printed prototype molds, dimensional tolerances and part-to-part repeatability are not equivalent to those achievable with production injection molding tooling.

Typical rapid prototyping capabilities and limitations include:

• Maximum shot volume: 25 cc (1.5 in³) — visual reference: ≈1.15 in cube
• Maximum moldable cross section: approximately 2.35 in × 2.35 in
• Maximum part depth: approximately 1.50 in
• Part geometry should be compatible with simple, straight-pull molds. Slides, side actions, and other features requiring lateral mold movement are not supported by the rapid prototyping process.
• Intended for small sample runs, generally in the tens of parts; minimum practical quantities are preferred
