our meter-mix-dispense equipment and
our company's 35-year history:
"With digital, servomotor-control
you can eliminate waste, scrap
and rejects ... minimize operator error ...
and increase high-quality output production."
John Phillips, Director of Technical Service for APT
APT's customers dispense cast urethane, epoxy, polyester, silicone, nylon, hybrids and many other flowable formulations
abrasive-filled and unfilled, precisely heated and at room-temperature.Our equipment dispenses single and mixed multiple-component formulations, in time-tested applications like open-casting, vacuum-potting and encapsulating (inside vacuum chambers), resin transfer molding (RTM), VARTM (vacuum-assisted RTM), low-pressure resin injection, wet-wound filament-winding (resin bath filling), solid (MBOCA) curative melting, powder curative melting, on-the-fly
thin-film resin heating and degassingand other automatic material-handling operations.If you need standard or custom-designed metering, mixing and dispensing systems, APT can help. We started over 35 years ago with automatic Quik-Melt ® MOCA melting equipment (now it's called MBOCA). One year later, we added automatic, mechanically-driven shot machines
Flying Wedge® metering and mixing systemscomplete with heated, agitated, vacuum-degassing tanks and on-demand MBOCA Melters for casting urethane elastomers. Two years later, among other items, we introduced epoxy processing systems to our line. This included manual and fully automatic, high-vacuum chambers, which gave our customers the ability to vacuum pot and encapsulate electrical and electronic components with air-free epoxy, inside air-free vacuum boxes. (Primarily these are high-voltage or critical, bubble-free, electronic component potting applications.)
On-the-fly, thin-film degassing came about when customers asked for higher outputs, along with a way to maintain vacuum on their materials. Our Continuous Thin-Film Resin Deaerators eliminated air and moisture contamination and the need to use dry nitrogen gas overpressure on the material.Our metering, mixing and dispensing systems have evolved from our mechanically driven HT-Series Piston Pump Wedge Machine and the CDM-Series Common-Drive Rotary Pump Machine. Over the past 10 years, we've added PLC/PC and Servomotor-Controlled SRD-Series, Rotary Pump Machines and Servo Driven ECS-Series Piston Pump Machines to our expanding product line.
The SRD and ECS-Series systems include state-of-the-art PLCs (Programmable Logic Controllers) and PCs, combined with digital, servomotor-controlled metering pumps. Coriolis mass flowmeters, mounted in-line between the metering pumps and the mixer, add a high level of QC protection to the metering and mixing process. What this means is that
with APTyou can rely on one machine supplier to offer you total control over your process. You have the option of selecting shots or continuous rotary pump dispensing as well as mechanical or servomotor-control. And when your application demands the very best, you can add coriolis mass flowmeters to virtually eliminate material waste and scrap.
What Do Our Latest Servomotor-Controlled Systems Give You
...that conventional machines can't ?
Accurate, digital control of ratio, temperature, output rate, mixed material output pressure, total volume displaced and mixer speed.
Unmatched ratio-change versatility with simple, pushbutton-presets and the ability to store your process variables in saved pour recipes.
The ability to vacuum cast air-free material into air-free mold cavities inside vacuum chambers
for electronic potting, encapsulating and vacuum casting, plus vacuum-assisted RTM parts.Thin-film degassing and delivery of precisely heated and agitated materials to the mixing machine. You can heat, agitate and vacuum degas your resin materials in APT batch preparation tanks or prepare materials on-the-fly in our Continuous Thin-Film Deaerators.
Save time and money by eliminating
operator error and guesswork.
APT's digital process control reduces waste and rejects to an absolute minimum.
Now you can meter, mix and dispense on-ratio, air-bubble-free material
to your molds with consistent,
digital accuracy and repeatability.
