Uni-forms Epoxy Preforms
Advantages to Liquid Epoxy

Liquid Problems

Solid Solutions

Drips

Liquid epoxy drips from syringes onto contacts or other unwanted areas of a component.

No Drips

Uni-forms are pre-shaped. They remain solid until they are heated, so epoxy flows only onto desired component features.

Mix Variations

Mixing and metering variations cause variations in liquid epoxy performance.

No Mix Required

Multi-Seals predetermines the ratio of catalyst to resin to produce a complete one-component system. Results are predictable and consistent.

Viscosity Creep

Liquid epoxy continues to polymerize as it is dispensed. This causes equipment clogs and variations in viscosity and seal quality.

Viscosity Consistency

The viscosity of Uni-forms remains consistent from seal to seal, batch to batch. The millionth seal will look the same as the first seal.

Pot Life

When liquid epoxy is not dispensed within pot life parameters, dispensing equipment can become clogged. Any mixed and unused two-part epoxy must be discarded.

No Pot Life Restrictions

Uni-forms have no pot life concerns. Unused material is simply saved until it is required for the next production run.

Poor Inventory Control

Liquid epoxy creates poor inventory control. Operators have difficulty estimating the exact amount of liquid epoxy required to seal a given batch of components. A large percentage of epoxy is wasted by misdispensing, improper mixing, clogged needles, or operator error.

Simple Inventory Control

Uni-forms simplify inventory control. Determining the number of preforms required for a given batch is as simple as determining the number of required seals.

Slow Manual Dispensing

Manually dispensing liquid epoxy is time and labor intensive.

Rapid Manual Dispensing

Uni-forms can be manually dispensed at rates that far exceed manually dispensed liquids.

Expensive Automated Dispensing

Automated dispensing systems for liquid epoxy are often expensive and require extensive operator instruction. Most equipment is prone to clogging and pot life concerns. Constant adjustments for epoxy viscosity variations, clogs, and air entrapment require highly skilled labor to run and maintain dispensing equipment.

Affordable Automated Dispensing

Uni-forms are well suited for a variety of automatic or semi-automatic equipment. Templates, Pick & Place, and Bowl Fed Gravity Tracks are all practical methods for loading Uni-forms. Automated loading rates can range from 200 to 600 ppm, depending on loader, component, and preforms design.

Variable Quality

Liquid epoxy seals vary in shape, size, and location, causing variations in seal performance and quality. Epoxy drips on critical component areas jeopardize product performance.

Precision Quality

Tight dimensional tolerances and viscosity consistency ensure repeatable, high-quality seals. Precise, consistent results contribute to product quality.

Costly

Expensive dispensing equipment, time-consuming procedures, skilled labor, wasted epoxy, scrapped components, and product returns from seal failures add high expenses to liquid epoxy dispensing.

Cost-Effective

Affordable loaders, inventory efficiency, reduced labor, minimal or no scrap, and product return prevention minimize the hidden costs often associated with epoxy sealing.

Difficult Pre-Cure Removal

Once liquid epoxy is dispensed, it cannot be easily removed from unwanted areas. As it starts to cure, reworking becomes increasingly difficult.

Simple Pre-Cure Removal

Uncured Uni-forms are easily removed from components, allowing for greater flexibility and reducing the number of scrapped parts.

Messy Cleanup

Liquid epoxy usually requires extensive cleanup procedures, including the use of toxic solvents and the disposal of epoxy waste.

Simple Cleanup

Uni-form epoxy preforms require minimal cleanup procedures. Preform residue is easily swept up. Handling equipment need only be wiped down once or twice a week.
