Cinpres adds a rep, offers

Gas injection technology (GIT) equipment provider Cinpres
Gas Injection has added to its growing network of service
and sales agents by appointing Simap as a representative for

Slovakia, the Czech Republic, and Hungary. Last year Cinpres
added a new agent in India, expanded its presence in China,
and appointed a new agent in Brazil.
In other news, the company says it now is licensed to use
Moldflow technology to analyze and advise its customers in
developing prototypes. This license only covers the molds that
Cinpres has been appointed to help develop and isn’t then
available for the molder to use independently of Cinpres; for
that, processors must acquire their own license from Moldflow.
Moldflow (Framingham, MA), acquired last year by
Autodesk, is the global leader in 3D digital prototyping and
analysis tools for the plastics industry.
Commented Cinpres Managing Director Jon Butler, “We’re
keen to help customers seize work currently being undertaken
using older processes...Some companies use the same materials
and the same processes, without question, for years. We’re
challenging the ‘we’ve-always-done-it-like-that’ mentality.”

New Moldex 3D simulation
software available
Plastics design and analysis software supplier CoreTech System
is marketing its newest product, Moldex3D R9.1, which the
firm claims will prove the fastest true 3D analysis tool available
to injection molders. This update of the company’s established
Moldex software provides a number of new functions and
enhancements, such as enhanced parallel computing technology
and a new meshing kernel. It also is said to offer users more
accurate analysis results on multicomponent molding than on
previously released software.
Place
According to the developer, key features in Moldex3D
R9.1 include the enhanced performance of parallel computing
that could help users see acceleration gains of anywhere
from 3-10 times. The benchmark of Moldex3D R9.1 on a
4-node Core i7 PC-cluster shows more than 10 times the
performance improvement of 3D flow analysis on a case of
one million elements. Accuracy also is improved. Some 485
plastic materials were updated and added to the database. It
is said to completely support two-color (2K) molding/overmolding.
The supplier also says that new Gate and Runner
design wizards can help reduce the runner and gate design
process dramatically.
Pricing and more detailed product information are available
through the firm’s agents, with contact information available
at its website.

SVGC added to hot runner controls
A sequential valve gate controller (SVGC) has been integrated
into the hot runner temperature control systems supplied by
Gammaflux Europe, the Wiesbaden, Germany-based subsidiary
of this company.
Designed
for use with hot
runner systems
with needle-valve
nozzles, the SVGC
opens and closes
each nozzle individually
and independently
of all
the others. This
permits sequential
filling of the cavity
so that flow
lines either are
prevented from
forming or are
shifted to those
areas of the molding
that are not
mechanically and/
or optically critical.
The reduced

mits a reduction in wall or section thickness, leading to weight
savings. Since the holding pressure is uniform throughout the
entire molded part, the reproducibility of the parts is said to
be improved. The integrated sequential valve gate controller is
available for use with 8, 16, or 32 pneumatically or hydraulically
actuated needle-valve nozzles.
