Dosing System Designed For Small Injection Molding Machines Trexel has introduced its new Series III MuCell System designed for smaller injection molding machines which are using screw sizes of 40mm or less.
The new Series III MuCell* system has been designed for seamless integration by injection molding machine manufacturers into their existing and new small machine designs. However, Trexel* will also sell the Series III MuCell system as a stand-alone package for those customers who do not want an integrated system. The Series III features the world’s first all-electric discontinuous dosing system for microcellular foaming. The Series III SCF System uses a unique and patented pulse dosing technology to provide accurate and repeatable discontinuous dosing for MuCell microcellular foam production. Trexel has announced that pricing for the new Series III system including SCF System, Interface Kit, and all operating rights will run between $55,000 and $75,000 USD, which means that molders using the new system can typically expect the Series III MuCell system to pay back rapidly on their original investment.
Engel and Arburg have announced that they will offer the Series III system
as an option with their line of smaller machines, and Trexel expects shortly
to announce additional manufacturers who will offer the Series III system
as an option on their smaller machines. Dr. Peter Neumann, CEO of Engel Machinery commented, “The new all electric Series III MuCell System from Trexel is perfectly compatible with Engel’s line of small all electric molding machines from a price/performance perspective. Engel intends to integrate the new Trexel system directly into it own line of machines in order to offer our customers a complete technical solution for their precision parts.” David Bernstein, President of Trexel said, “The MuCell process offers producers of precision electrical/electronics components major operating cost reductions as cycle times can be cut by as much as 35% along with moderate weight reductions. However, the main advantages lie in the reduced viscosity afforded by the MuCell process and the extraordinary dimensional stability which is achievable. Despite these compelling advantages, few of our customers to date have been able to justify the initial cost of the system for their smaller machines. “We believe,” said Bernstein, “that the Series III
system will find wide application as a cost-effective solution for electrical
and electronic applications used across numerous industries. The MuCell
process eliminates many of the key molding constraints, while providing
the dimensional stability needed for these smaller parts. The time-consuming
mold re-work typically needed to bring E/E parts into dimensional conformity
is dramatically reduced, and the end result is that time to market is
shortened,” he added. The Series III SCF system is designed to take a supply of nitrogen from
a high pressure cylinder and provide a precise dose of nitrogen at a chosen
set point. The nitrogen supply is fed to a gas piston. An electric drive
motor is attached to the gas piston, compressing the nitrogen in the gas
piston to a predetermined pressure. This pressure becomes the supply pressure
for the hardware required for a pulse dosing system. The MuCell process is primarily employed in the injection molding process to produce lower cost precision parts with a consistently high quality and exceptional dimensional stability, where foaming has not historically been deployed. Microcellular foaming technology was originally conceptualized and invented at the Massachusetts Institute of Technology (MIT) and in 1995 Trexel was granted an exclusive worldwide license for the further development and commercialization of the technology. Today there are hundreds of MuCell parts, both molded and extruded in commercial production today around the world and in excess of 300 machines in operation. Examples of MuCell products include electrical components, electronics connectors, internal business equipment and printer components, a variety of packaging applications and a broad array of automotive products including HVAC components. To support global adoption, Trexel has established a global network of exclusive manufacturing relationships to produce the company's proprietary precision engineering equipment. MuCell support centers are located in the U.S., Germany, Japan, Hong Kong, China, Singapore, Australia and Korea. Trexel is the exclusive developer of the MuCell microcellular foam technology
and has an extensive portfolio of patents in the U.S., Canada, Europe,
Japan, Korea, and Asia. Trexel’s primary business is the supply
of MuCell Systems for the production of foamed injection molded and extruded
articles. It also provides world-class engineering support, training and
other services, and the equipment and components integral to the MuCell
process. In support of these activities, Trexel operates a foamed plastics
development laboratory in its Woburn, MA facility including injection
molding and extrusion equipment. Injection Molding Processing Jobs - Post Employment Opportunity!
