Conair Franklin now offers four new versions of its CAML resin loaders. The new models are designed to suit specialized applications, minimizing height over the receiving hopper, bin or drum.
CAML-LPS conveys materials up to 15 feet at rates up to 250 pounds an hour. A low-profile lid/inlet has a built-in exhaust filter under the lid.
CAML-LPL has a larger, high-dust filter cartridge on the top of the lid-inlet assembly. It conveys material 20 feet at up to 400 pounds an hour.
For lower throughput requirements, moving up to 60 pounds an hour 15 feet, the Franklin, Pa.-based firm offers the CAML-M.
CAML-EV can be used to evacuate regrind from granulator drawers or unload bulk materials into drums.

United expands line for pipe extrusion
United Plastics Machinery Inc., which makes custom belling-socketing equipment and perforators for extruders of plastic pipe, has expanded into a complete line of downstream equipment for small-diameter chlorinated PVC and PVC pipe.
The new equipment from the Exton, Pa., company includes a puller/haul-off, vacuum tank, saw and automatic-bundling system.

Milacron system cuts overmolders' costs
Cincinnati Milacron Inc. engineers developed a new, less-expensive way for overmolding, the process to injection mold hinges or ball-and-socket joints complete, requiring no post-mold assembly.
Traditionally, overmolding has required special injection presses designed to mold two incompatible materials. That guaranteed that no bond would form between the two halves of the joint.
Through a Milacron technique called ``ice-cold'' molding, overmolding can be accomplished with just one material on a standard Ferromatik Milacron press.
In ``ice-cold'' molding, a set of cooling inserts is placed inside the mold and held to about 32§ F, to mold the first half of the joint, or the parison.
``Though the second half of the part meets the parison at near-mold temperature, the resulting temperature at the point of contact never rises to the materials diffusion limit temperature, so no bond ever forms,'' said Bob Hare, general manager of Ferromatik Milacron USA.
Cincinnati Milacron is based in Batavia, Ohio.

New DuraFlight 2420 touted for long wear
New Castle Industries Inc. has introduced the DuraFlight 2420 Combination screw and barrel for extrusion.
Touted for its long wear, the 2420 has DuraFlight's CX-3 hardsurfacing applied to the primary flight lands. The barrel is centrifugally cast using the SR-2420 grade of high-tungsten carbide bimetallic liners from Bimex Industries of Wales, Wis., which was acquired recently by the New Castle, Pa., company. The screw and barrel is suited to running highly filled, abrasive resins and high-viscosity resins that cause a high level of adhesive wear.

Abramo says system cuts bottles' weight
R.J. Abramo Associates Inc. has teamed up with a consulting firm to offer new core rod technology that Abramo says can reduce the weight of injection blow molded bottles and jars by 10-15 percent.
Traditionally, injection blow molded bottles and jars have minimum weight limitations because of the thermal stability of the annular wall thicknesses of the preform. Abramo said the new core rod system can be retrofitted onto existing molds by replacing existing core rods.
Holliston, Mass.-based Abramo and its partner, Hart Systems of Stockport, England, said the core rods also can reduce weight in the shoulder and base areas by up to 5 percent, by a more-uniform material control and distribution to those areas.

XG Series blender aids metering range
Process Control Corp. has introduced a new XG Series of continuous gravimetric blenders.
A new drive control with closed-loop feedback increases the range of each ingredient feeder, meaning operators do not have to change auger sizes as feed rates change from recipe to recipe, the Atlanta firm said.
One innovation is hoppers located above the feed auger, resulting in a more consistent head pressure.
The XG blenders stand only 66 inches high, with a footprint measuring 58 inches by 391/2 inches.
Output from all feeders moves through a cascade mixer, which has no moving parts. The blend moves down to a plug-flow hopper.
