Conforma launches inspection service
Conforma Clad Inc. of New Albany, Ind., has launched its full-service extruder barrel inspection and refurbishment program, nationwide.
Dan Ludwig, director of sales, said Conforma Clad has always offered recladding and refurbishiing of barrels and liners that contain its tungsten carbide wear protection. But customers said they wanted a one-stop shop to refurbish any make and model of co-rotating, segmented twin-screw extruder barrels
The service extends the life of worn extruder barrels. Inspection services, including cleaning and pressure and flow testing, are performed at no charge. After completing the inspection, Conforma Clad recommends any repairs required to restore the barrel to a like-new condition.
The company's barrel liners consist of tungsten carbide material that is bonded to a 4140 steel substrate. The combination provides added ductility, virtually eliminating failures associated with rigid liners such as weld separation of the collapse of sleeves, according to Conforma Clad.

Engelhard offers pigment alternative
Engelhard Corp. debuted a cost-effective pigment alternative to molybdate orange.
Synergy Orange 6113 is a mid-shade orange with enough heat and weather stability for most exterior plastic applications, such as wire and cable, construction fencing and tool housings.
The Iselin, N.J., firm said regulations mean handling molybdate orange adds cost to using the pigment but conventional alternatives have tended to be expensive. Engelhard claims its new product delivers performance at less expense than other substitutes.

Evalco improves on EVOH series polymers
Eval Co. of America introduced a new line of ethylene/vinyl alcohol polymers with enhanced properties.
The 7 series of Eval products show improved thermal stability, better processing and more adhesion without sacrificing barrier or mechanical properties, according to the Houston firm.
Grades are available for film extrusion, blow molding, injection molding and thermoforming. Improved processability means less die lip buildup and stable viscosity over long extrusion times, Evalco said.

Dynamic introduces conveyor features
Dynamic Conveyor Corp. has introduced a metal-detection feature for its conveyors, for inspecting plastic scrap for metal contaminants as the scrap is conveyed to grinders for reuse.
The company in Muskegon, Mich., also said its Tote Stacking System allows the desired number of parts into each bin before another bin is automatically dispensed. It can run unattended.
Dynacon also said it has added optional heavy-duty motors and take-up modules. Also, a new leg set design automatically levels the conveyor while being easy to set up.
