Who we are

At EXACT Dispensing Systems, we help manufacturers find solutions to meet their single and plural component dispensing needs.

We never do it by selling a one-size-fits-all product.

The Company

EXACT Dispensing Systems is part of The TASI Group of companies, which is comprised of three product platforms linked by a disciplined focus on Flow, Leak & Measurement, and Test & Assembly.

As an integral part of TASI Flow, EXACT Dispensing Systems delivers world-class industrial equipment for the dispensing of single-component fluids and plural-component reactive resins such as epoxies, urethanes, and silicones.

Markets include: Aeronautical & Aerospace, Automotive, Defense, Electrical & Electronic, Filtration (air & liquid), Medical, Marine, Sporting Goods, Telecommunications, Transportation, Consumer and General Industrial.

During its first year in business, EXACT completed development of a positive displacement inline piston metering system that has become a standard in the industry.

Constant improvements over the years have resulted in one of the most accurate, robust and trouble-free metering systems on the market today.

With over 30 years of experience plus total in-house capability, EXACT Dispensing Systems is in a unique position to serve its diverse customer base with products and systems that integrate efficiently and sensibly with their process requirements.

6

Vacuum Potting

Meter/mix integrated with an EXACT built Vacuum Chamber.

Provides air-free potting and improved impregnation in difficult to reach areas (i.e. around pins, under circuit boards) ensuring void-free encapsulation.

Critical for high voltage components that are prone to corona effect.

Some processes allow same day shipment of vacuum-potted components.

Doming & Scripting Doming: The application of an optically clear doming material

(urethane & epoxy) to the surface of labels, nameplates or decals for the purpose of creating a clear raised (“domed”) surface. Used to enhance and protect the appearance of these products.

Scripting: An automated doming system incorporating a precise EXACT Servo Bead Meter/Mix with XYZ motion to traverse scripted products.

Meter / Mix Products

Piston Metering Systems– Single Acting– Double Acting

Blind Rod Metering Systems

Gear Pump Metering Systems

12

Meter / Mix – Single Acting

Meters on one side of the pistons

Recharges after full stroke of cylinders

Suited to use with abrasive, filled resins that settle out of suspension.

Multiple sizes to suit production needs.

13

Meter / Mix – Double Acting

Meters on both sides of the pistons Provides continuous output Suitable for use with some

filled materials Multiple sizes to suit

production needs

14

What Differentiates Our Piston Systems from Others?

EXACT Others

Linked Diverter Valving

Offers the following advantages

IndependentCheck Valves

Ensures positive flow of material into and out of the metering cylinders

Possible lead / lag issues due to

non-synchronous valve actuation

No phasing adjustments

Phasing adjustments often required

15

What Differentiates Our Piston Systems from Others?

EXACT OthersLarge metering cylinders

allow incremental shot sequencing

Recharge required after each shot

Less motion for a given volume, means less wear

Increased wear

Piston seals always in contact with the metering cylinder wall

A/B seal engagement subject to change as seals wear

Inline cylinders, no racking Side by side orientation subject to racking and off ratio conditions

Fixed ratio……no ratio drift Variable ratio linkage subject to variances

16

Gear Pump Metering

Provides continuous, precise fluid delivery Servo Bead, excellent for integration with XY

dispense platforms, provides precise deposition rates.

For use with non-abrasive materials

17

XY Motion Platforms EXACT can integrate any of its meter/mix

systems with commercially available XY motion platforms from most manufacturers.

EXACT also designs and manufactures custom systems to suit your needs. Typical work envelopes range in size from 12"x12" up to 4'x8'.

Some of the features of our motion systems are:

• AC Servo Motors driving hardened ball screws• THK type rails to provide large payload capacities and

long-term durability. This is in contrast to less robust belt driven motion systems.

• User friendly Windows style software • 32 bit, RISC processor • Easy to use sequence style

programming
