HRS flow introduces HYFlow technology Tekni-Plex introduces new Pentafil L + Fill
RS flow has recently introduced HYFlow
Htechnology for precise control for hydraulic
needle drive, wear-resistant design for abrasive
plastics, high quality film injection molding. New and
advanced developments around HRS flow's hot runner
systems are specially designed to increase product
quality in cascade injection molding. This includes the
only recently launched HyFlow technology developed
for applications with hydraulically actuated cylinders,
in which the opening and closing speeds and the
positioning of each individual pin can be precisely
adjusted via the oil flow rate. Now also available in the
market is the Hyper-GF series for processing abrasive
thermoplastics. On the application side, uses a current
pilot project with a customer, to show how
FLEXflowEvo, the recently presented advancement of
the FLEX flow technology for servo-electrically driven
valve gate systems, can be used to achieve outstanding
results when back-molding sensitive films. HyFlow uses
a controller with a user-friendly interface to set the
lock position of each individual pin. The opening and
closing speed for each nozzle can be set by a manual
adjustment mechanism. This allows for controlling the
melt flow rate in a way that cascade injection molding
HRS flow results in a uniform mold filling process
without sudden pressure drops and the associated
surface defects. The positioning of the pin also allows
for optimal balancing of the pressure distribution in
the cavity during the entire injection process. The new
Hyper-GF series, available for HRS flow's Ga and Aa
nozzles, is designed to improve the long term
performance of the hot runner system when processing
highly abrasive materials such as glass fiber reinforced
materials.

bench-top vial filling/sealing machine
ekni-Plex has introduced a new bench-top vial
T filling and sealing machine ideal for lab research
and small quantity start-up production. Called the
Pentafill® L + Fill, the machine now adds filling
capability to the Pentafill L unit which only seals the
vials. The new machine accommodates five-unit strips
of 0.33-, 0.6-, 1-, 3-, 5- and 10-ml plastic (PE, LDPE,
LLDPE, HDPE, PP and EVOH barrier) vials. To execute a
fill/seal, an operator loads the five-unit strips into a
holder, which is then manually inserted into the
machine. The vials are filled and sealed automatically,
followed by manual removal of the holder. “Up until
now, pharmaceutical companies and labs had to
manually fill small-scale production vials before
inserting them into the machine for sealing. This
resulted in fills that were frequently imprecise and
therefore not ideal for lab research or therapeutic
use. To help eliminate that issue, our customers asked
us to create a unit that would provide precision fills,
each and every time,” said Melissa Green, global
senior director marketing and strategy, Tekni-Plex
Healthcare Packaging. The Pentafil L + Fill allows the
user to mimic the results of a full-scale production
machine via a compact, bench-top unit. The machine
includes a heating head, cold-molding pliers and a
sealer. It features interchangeable holders for
different vial capacities and simple external controls
to execute the fill/seal. The Pentafil L + Fill is available
in the United States from Tekni-Plex's LF of America
business, and in Europe from its Lameplast operations.
