Improved
ResinWorks™ System has Smaller Footprint;
New Features Make Central Materials System Easier
to Use
The
Conair ResinWorks™ central drying/conveying
system has added new features to make the system
even easier to use. Air manifolds integrated into
hopper sleds, a new slide valve design for the
material conveying manifold, automatic air-flow
control, and a new material-purge valve are just
a few of the improvements Conair has made to this
convenient material handling and conditioning
system.
With
ResinWorks centralized drying and distribution,
material changes are made faster because resins
can be predried and conveyed to processing machines
quickly. Processors can remove individual dryers
from beside or atop machines. They can cut labor
costs dramatically and improve operator safety
by eliminating manual handling of resin. And they
can improve finished product quality with better
control over drying and blending, and reducing
potential for contamination. Even a medium-sized
molder can easily save hundreds of thousands of
dollars every year by cutting energy, material
and labor costs, and increasing overall productive
up-time.
Although
Conair uses a menu of standard components as a
starting point, each ResinWorks system is custom
configured to meet specific user requirements
— from the number of different materials
being processed to the number of molding machines
being serviced. Core components, including drying
hoppers, desiccant dryers, blenders, vacuum pumps
and loaders, are pre-assembled and delivered with
material-handling controls, conveying pipes and
valves, and other components to ensure precise
resin drying, blending and delivery.
Space
Savings
Conair engineers have reconfigured many of the
basic components in the new, improved ResinWorks
system to dramatically reduce its footprint, saving
valuable manufacturing floor space. For instance,
the main electrical enclosure has been moved to
the front of the system, making it easier to access
and eliminating the need to leave space behind
the sleds for service access. Likewise, individual
drying air heaters have been moved out of the
way and underneath the hoppers.
The
sizeable ductwork required for moving drying and
conveying air to and from the material hoppers
has been fully integrated into the ResinWorks
sleds. This approach not only saves space, but
the ducts actually become part of the sled structure,
making it stronger. The ends of the ducts on each
sled are gasketed, so when multiple sleds are
bolted together, a complete air-handling manifold
is created.
Simplicity
of Operation
Several innovations make ResinWorks easier than
ever to operate:
New
Purge Valve
ResinWorks is designed with a purge valve that
meters only a small amount of material out of
the drying hopper at any given time and then conveys
it immediately and completely to the processing
machine. This prevents dried material from regaining
moisture while it sits in a conveying line. The
purge valve in the new, improved ResinWorks system
is a spin off from Conair blender technology,
and it actually comprises both a metering valve
and a distribution box built into a single, compact
casting. A convenient access door opens wide to
allow easy cleaning, and the discharge elbow rotates
360° to make it simple to connect conveying
lines. The unit costs as much as 20% less than
previous-generation purge valves which, in a ResinWorks
system with ten hoppers, could save processors
well over $1000.
With
all these new features, the Conair ResinWorks
system can be almost anything a processor wants
it to be. Up to five drying hoppers, each sized
specifically for either multi-machine/long run
or single-machine/short-run operations, are factory
assembled onto a sled-like base and fitted with
heaters, controls, dry-air manifolds and purge
valves for easy place-and-play installation. Multiple
sleds can be integrated for larger installations.
The ResinWorks system can also include a gaylord
or bag station, allowing an almost unlimited number
of different materials (dried or un-dried) to
be managed through the central resin distribution
manifold and control system. A Conair gravimetric
blender can mix different materials and additives,
which can then be conveyed to a drying hopper
or directly to processing machines.
