Advanced Process Technology, Inc.
designs and manufactures high-performance
machines including
cast urethane processing equipment, epoxy potting and vacuum
encapsulating equipment,
resin transfer molding and composite RTM, VARTM, metering, mixing,
dispensing and injection equipment
for continuous output and shot output of
plural-component, abrasive-filled and unfilled castable resin formulations.
Also, a full line of heated, agitated, vacuum, pressure,
mixing tanks
for heating, agitating and degassing cast urethanes and epoxies.

How can we
help you?...
For
nearly 40-years, APT has helped
cast urethane, epoxy, polyester and nylon resin processors meet hundreds of
machine-process and laboratory requirements for degassing,
open casting, bottom
filling, closed mold
mixed material injection, epoxy
vacuum potting inside vacuum chambers,
epoxy resin transfer molding -
RTM VARTM -
and resin bath-filling for filament winding applications.
Our
cast urethane machines and epoxy resin dispensers
provide processors
with the ability to enter digital presets and to easily select pour recipes at an
operator-interface control panel to cast and mold products with true digital
repeatability. Your finished parts can have precise, preset, physical properties.
What that means to you is that you can have QC control just before it's made, far less
scrap, far more accuracy and increased profits.
APT's SRD- and ECS-Series
servomotor-controlled, metering, mixing
and dispensing
machines provide the process variable controls needed to handle your most demanding
application requirements, most notably precise,
all-digital, metered-resin flow control.
Instantaneous closed-loop ratio
control insures consistent,
on-ratio parts production.
Our
continuous rotary gear metering pumps handle unfilled resins. Our
positive-displacement piston metering pumps handle highly abrasive-filled
and unfilled resins.
These systems optionally include state-of-the-art,
straight and curved-tube, coriolis mass flowmeters for closed-loop feedback ratio control, PLC or
Flat-Panel PC control and continuous material recirculation together
with servomotor-controlled
gear or piston pump metering
systems. Combined, these essential items give you ...
- Accurate,
digital control of all process variables
ratio, vacuum,
temperature, output- rate, volume-displacement, pressure in the mold and mixer-speed
to make your most difficult jobs easy.
- Saved process-control recipes
can be selected by
part number or name to insure part-to-part repeatability.
- Unmatched ratio-change versatility with simple, pushbutton-presets
no need to change gears and no need for mechanical adjustments.
- Material
recirculation
to insure homogenous material temperature
control throughout the system's tanks, lines, metering pumps, mixer and back to the tanks.
- Alarmed
(over/under setpoint) ratio verification
stops scrap before
it's made for instantaneous QC control.
Quality control is what these systems
from APT are all about:
Save time and money by eliminating operator error and guesswork. APT's
digital process control cuts resin waste and rejects. Now you can meter, mix and
dispense on-ratio, air-bubble-free material to your molds with PLC-controlled and coriolis
flowmeter-verified, digital accuracy.
To
eliminate air-bubbles and voids, we provide you with:
-
Heated batch preparation tanks
for
heating,
agitating and degassing
to prepare
air-bubble-free batches of resin.
-
Continuous thin-film degassing and continuous delivery of precisely
heated and agitated materials to the mixing machine. You can heat, agitate and
vacuum degas your resin materials on-the-fly in our Continuous Thin-Film Resin Deaerators at up to 40 lbs/min.
- The ability to vacuum cast air-free materials into air-free mold cavities inside
one of our standard or custom-designed vacuum chambers.
Vacuum-casting is typically reserved for electrical and electronic potting and
encapsulating, where the mixed-material pot life is long enough to accommodate this
process. Also, for RTM parts, where the preform
needs to be injected with mixed resin from 5 to
600 PSI. Plus, molds can be
vacuum-assisted for epoxy-composite VARTM applications.
