problems on large parts like automotive instrument are designed for heavy-wall containers made of
polycarbonate, E-PET for extrusion blow molding and
other tough resins for extrusion blow molding and
injection blow molding.
“This technical upgrade helps our customers meet
the stringent deflashing requirements of high-impact
materials,” said Siva Krish, Proco Machinery’s vice
president of sales. “These new deflashing options are
already being used by a couple of our customers in very
demanding applications.”The Pneutrium Plus deflasher
is designed to remove flash on containers as large as
10 gallons. It can be configured to deflash multiple
containers simultaneously. Guide rods give accurate

molders eliminate cosmetic defects on sequentially filled
parts caused by sudden flow front accelerations and
stagnations created when the delayed pins open. Giving
molders better control of the pin allows for individual
flow rate control of each nozzle to balance family molds
or fill complex multi-gated geometries.
Synventive introduced and demonstrated the technology
at a Nov. 30 event in the Detroit suburb of Ferndale, which
was attended by molders, toolmakers and automakers.
Synventive officials touted the easy-to-use control
interface, and the ability to upgrade to the system
less expensively than other pin-control technologies.
