 AUTOMOTIVE
To a automotive parts supplier - V-LINE Two-Stage Plunger System has
various benefits. First, V-LINE system inherently promises repeatability over
long-term. The benefit of closed loop molding lends to improved process
stabilization evident through improved part weigh consistency as measured
through standard deviation. Second, V-LINE reduce your maintenance cost.
Negligible axial movement of the plasticizing screw lends to dramatically
reduced abrasion wear. The result is increased life of screw and barrel
components by a factor of 10 to 20 times that of conventional reciprocating
screw system, in addition to a replacement cost of tip assembly, which V-LINE
system eliminates from its system. Third, V-LINE system improves black specs,
contamination, and gasification. Plasticizing unit design provides an extremely
uniform melt condition while eliminating opportunity for material backflow or
degradation. The result is less contamination and gasification in your molded
parts. Finally, V-LINE system makes possible the duplication of mold processing
setup parameters for customers with multiple machines or locations. Machines
difference is minimum in V-LINE system due to pre-dosing before injection
phase.
 Vast experiences using high performance polymers such
as PPS, PEI, PEEK, and LCP
Reduction of outgas - less contamination, and minimize mold
cleaning cycles
Least perishable components - reduction of maintenance cost
Outstanding performance for sensitive inert molding process
 MEDICAL
To a medical molder - The melt stream for V-LINE system mold parts is much
cleaner than that of other machines for several reasons. First, we employ no
check ring. Therefore, no material can stick and degrade on the check ring.
Second, due to our design, there is absolutely no flow-back of material,
decreasing the residence time of the plastic melt. Third, there is relatively
much less metal-to-metal contact (compared to a ring-type check valve, and much
less than 3-piece interlocking type check valve), so no metal find its way into
your parts. Finally, our patented bypass nozzle ensures a "first-in, first-out"
scenario for the plastic melt.
Repeatable process on high cavitation applications /
Reduction of part weight variations
Small injection units for "residence time" sensitive polymers
such as PEEK, PLA, PGA, TPU and LCP
Micro molding capability to adapt miniaturization of
medical device development
Highly endosed by many medical OEMs especially in
long term implantable applications.
 OPTICS
Including Ophthalmic Lenses, Front-lighting & Back-Lighting
Applications.
To an optical molder - V-LINE system has no check ring, and employs an
extrusion grade screw, i.e., the compression of the melt occurs over many
flights, not just a few in the transition zone of a typical injection molding
screw. For this reason, our parts have been tested and shown to have much less
molded-in stresses. This is important because a back-lighting display, with a
very high flow-path to thickness ratio, will not warp. Also, our parts have
much less haze or optical birefringence due to fewer molded-in stresses.
Further, because the V-LINE screw moves forward only a negligible amount
(approx. 1.5mm during shut-off), there is no trapped air in the melt, and thus
none in the parts.
Special Lens specifications available
Simple compression fuction to improve sink
Easy to find optimizing injection condition in between
weld and flow mark
Achieving more candela by high transcription
 ELECTRICAL / ELECTRONICS
To a connector or insert molder - Because V-LINE employ no check ring,
there is no pressure spike at the start of the injection phase to close the
check ring. Also, we have complete and total shut-off before injection phase.
When you couple those truths with the fact that we have state-of-the-art shot
size metering control, we have a very repeatable process in which the plastic
stream is always account for. A cushion on the V-LINE system process is at
least one order of magnitude more precise than other micro-molding machines,
i.e., if the cushion on a conventional reciprocating screw system varies 0.200"
+/- 0.030", the V-LINE process varies by 0.200" +/- 0.002". For these reasons,
inserts and/or mold cores with miniscule cross sections will not become damaged
or displaced during the injection phase.
