Avure Laminaotor (WIP; Warm Isostatic Press)
A proven process
Isostatic (equal
on all sides) pressure has been used for over 40 years to densify and
improve the durability of critical metal and ceramic parts in aerospace,
automotive, and other industrial applications. This versatile process is now
offered to manufacturers in the electronics industry as a cost-effective means
of
laminating hybrid chips, MLCCs, ferrites, varistors, multi-layer PZTs, LTCC,
electronic filters and similar ceramic components.
Isostatic pressing means productivity
With the AVURE
Isostatic Laminator, there's no trade-off between quality and speed. This
high-efficiency unit produces laminations of multi-layer ceramic (MLC)
modules at 20 times the throughput rate of traditional heated plated presses
(Hot Press). And even with this high productivity, the quality is virtually
flawless:
Evenly distributed lamination pressure prevents package distortion.
Shrinkage is precisely controlled, and part-to-part variation is eliminated.
Multiple packages and sizes can be processed in a single 3-10 minute cycle.
No rounding of edges or camber
No edge trimming
No in-cycle part rotation
Rejected parts and scrap costs are significantly reduced
First in the world in isostatic pressing
AVURE has designed,
built and sold more hot and cold isostatic presses than any other company in the
world. AVURE's experience and engineering skill has also
made it the undisputed leader in the growing world of isostatic lamination. Many
customers have already come back to AVURE for their second or third
laminators. They like the product and the extra benefits of dealing with the
industry leader:
ISO-9001 certified quality system
CE Mark certification
Wide selection of standard and custom designed models
Complete design, manufacturing and testing from a single source
Excellent field service with a full-time staff of technicians
Superior safety record in high pressure equipment
Huge productivity gains

The AVURE Work Basket |
Competitive "Lamination Chamber" |
|
The adjustable work basket suspended under the pressure vessel cover permits a variety of horizontal and vertical part arrangements. With this design, the entire volume of the vessel can effectively be used to process parts. |
Competitive laminators use a cavity inside the vessel to serve as the work zone. This small area has nowhere near AVURE's loading efficiencies. |
The most visible
difference between the AVURE Laminator and other units is its large, fully
accessible workzone. In addition to its overwhelming productivity advantage
over uniaxial platen presses, the AVURE design will process 4 to 7 times more
parts per cycle than other equivalently priced laminators. The suspended work
basket will
hold vacuum-bagged parts in horizontal stacks or vertical rows, and can
accommodate packages up to 20" in length. With all these superior production
efficiencies, a
AVURE Isostatic Laminator can pay for itself in a matter of months.
Threadless
Pin Closure
Unique, quick-opening design decreases vessel fatigue by reducing axial and
bending stresses.
Workzone Fully accessible work basket with entire cylinderical area available for lowest laminating cost per cubic inch.
Pressure Vessel
Single wall construction, engineered to minimize stress concentration. Stainless
steel material resists
corrosion far more than carbon steel vessels. ASME code stamp available for
unrestricted operation in any state in the
U.S.
Console Top Stainless steel for corrosion-free work area.
Heaters
Insulated ceramic band heaters positioned at perimeter of
pressure vessel for easy accessibility. Programmable
automatic preheat start timer included.
Control Unit
Includes PLC, digital pressure indicator, and OIT (Touch Panel) for cover up/
down, pin in/ out, cycle start,
letdown/ stop, and emergency stop with buzzer.
Quick Fill Reservoir Innovative gravity design speeds cycle time, requires no fill or drain pumps.
Pressurizing
System Air driven pump with all required valves, sensors,
filters and controls. All valves supplied with stellite
tip stems and replaceable seats.
Operation
1. Using the OIT (Touch Panel), user-selected cycle parameters are entered:
presoak temperature, presoak time, dwell pressure, and dwell time. Typical cycle
parameters are 70~80 degree C, 3000~5000 psi and 3~10 minutes
total cycle time.
2. With the cover in the raised position, the vessel is automatically filled with water from a gravity fed quick-fill reservoir.
3. Operator assembles
part layers and laminating tape on a registration plate and inserts into a
plastic bag which is evacuated and sealed. The pre-assemble vacuum
bags are placed in the work basket attached to the vessel
cavity.
4. The cover/ basket assembly is lowered into the fluid-filled vessel cavity.
5. The complete
processing cycle then is initiated with a single button on OIT: Preheating,
pressure build-up to set point, dwell period, depressurization, and lifting of
the cover/ basket assembly. Uniformly densified laminated
parts are then removed.
