Acute gastrointestinal illness has been linked to public drinking water systems in the U.S., which has driven the development of new microbiological test methods. Currently, typical laboratory water vial testing samples can take up to two weeks of processing for final results of clean water free of harmful E.coli and Total Coliform bacteria contamination.
A turnkey, single-use, water test cartridge and
automated monitoring system has been developed to reduce testing to
within 2-18 hours, depending on the level of contamination. The
cartridge incorporates overmolded rigid plastic and optical grade LSR
(liquid silicone rubber). The test cartridge leverages a 2-shot mold and
subsequent robotic transfer into an integrated assembly cell to
complete six processes outside of the molding area, and then put in a
box ready to ship.
The cartridge system created and designed by Roembke Mfg.The stone mosaic
series is a grand collection of coordinating Travertine mosaics and
listellos. & Design, Inc. (Ossian, IN), ENDETEC (Kingston, ONT), and
Engel Machinery North America (York, PA) initially focused on
materials, which had to be clear to see the fluid inside the cartridge
and pass gamma sterilization processing. Then engineers focused on
eliminating inhibitors in the chosen plastic, to get an optimal seal
with the LSR. Finally, the materials could not interfere with the
microbiological growth that takes place during the test process.
plastic selected was a modified polypropylene and the LSR was an
optically clear 1003-grade silicone. The materials were finalized by
tweaking the thermoplastic process to figure out estimated cycles,
temperatures of the mold, sealing, and so on.

system, integrated user interface with interpretive software, and a
special test cartridge for the detection of E.coli and total coliforms.
Key design elements in the cartridge include a plastic vial with a
living hinge and cap, coupled with an optically clear LSR plug/nub at
the bottom of the vial for testing the water through the optical system.
ENDETEC worked on the seal design between the plastic and LSR
materials and determined that there could be no chemical bonding agent
between them, giving rise to another reason for choosing the special
optical grade LSR. To meet the required temperatures, focus was directed
to thermoplastics. This was done to produce an effective seal that
would not leak fluid between the materials. The set-up was for
pre-production testing and designed with the capability to eventually
expand to higher cavities (4+4) once the production process was proven
The next decision was whether to mold the materials
separately and assemble them or to overmold them. Roembke and Engel
worked together in developing the 2-shot molding cell and LSR tooling
prototypes. Testing these prototypes consisted of seven injection
molding presses ranging from 35 tons to 200 tons.
addressed the first stage of automation in the prototyping by enlisting
Pro Systems (Churubusco, Indiana), to integrate the turnkey automation
into the machine. Due to operating height restrictions, a 6-axis robot
was used for the final assembly, completing six processes outside of the
molding area. This process also included placing a water-soluble pouch
containing pre-measured amounts of growth media that support the
enrichment of any target bacteria present in the sample for each water
A series of pre-production testing,We can supply howo truck
products as below. prototype tools were modified for the plastic vial
and LSR component to complete the 2-shot mold/press process. One press
was used to mold the plastic vials, which then moved to the second press
to apply the LSR tool. The primary machine used was Engel’s Victory
200H/80L/160 Combi. This 160-ton single cavity machine with wide platens
equipped with two injection units was used to run the two separate
materials. The primary (200H) was for thermoplastics and the secondary
(80L) was for LSR.
Ultimately, the Roembke mold was a single
drop cold deck with a standard LSR valve gate design featuring side
injection versus back injection for the plastic.We offer the largest
range of porcelain tiles
online. The final Engel machine was a standard 2-component machine that
incorporated the smallest diameter screw possible (12 mm) on the
injection unit. The wide platen machine leveraged a special ejector
pattern for the tool design centered behind each application for the
thermoplastic and LSR. Servo valves were used on both ejection units
with valve controls used for optimal speeds and pressures.
you, Steve, and good morning to everybody and let me wish everyone on
the call a happy New Year as well. And perhaps you could now turn to
Page 3. Prior to giving you an overview of our results by market, I'd
like to give you a quick high-level summary of the key points that
resulted from this quarter. As you now know, we reported record revenues
for the quarter, and we were pleased to see such strong growth in an
uncertain operating environment. Our record revenues were driven
primarily by new product launches. In recent years, the economic cycle
has overwritten the normal seasonal pattern that we see for orders.
However, this year, we did see a normal seasonal slowdown in orders,
particularly in the consumer and mobile sectors. The bookings pattern,
frankly, continues to be very volatile on a day-to-day basis, and it's
very difficult to predict the overriding trend in the market. We still
believe that there are growth opportunities as we move into calendar
year '13 and during the last quarter, we completed a number of
investments that we think will help our future growth. As I said in the
release, we are,New Ground-Based indoor positioning
Tech Is Accurate Down To Just A Few Inches. however, waiting until the
post-Chinese New Year period before, we believe, we can get a stronger
fix on how calendar year '13 will turn out.
The investments we
have made in the last quarter include completing our Affinity Medical
acquisition, which is doing very well and reported record results in its
first couple of months, and CapEx for our new plants in the Philippines
and a new facility in Korea, clearly a high-growth market. In addition,
we continue to invest in R&D, particularly in high-speed, high
power and microminiature products.
During the quarter, we
completed the due diligence on a couple of acquisitions that we decided
not to move forward with at this time. As we've stated in prior calls,
our acquisition focus will continue to be on the industrial, medical and
value-added areas. Despite a challenging environment, our organization
continues to operate extremely well. For the quarter, we reported record
on-time delivery performance and record quality metrics. We believe
that these outstanding levels of customer service will continue to help
us win business and key customers.
