Cooling tanks made for medical tubing
Conair Group Inc. designed its MedVac flood-cooling tanks especially for medical-tubing extruders.
Available in five models, the tanks can be used to make any size or configuration of tubing, from multilumen microbore heart and brain catheters to large-gauge commodity medical tubing.
Precision vacuum control, a standard feature on MedVac tanks, combines the accuracy of digital control with the convenience of a potentiometer. Operators simply turn a knob until they reach the ideal setting, the firm said.
Other features include a cleaner interior design for more sanitary extrusion conditions, the availability of medical-grade filtration and a design that is easy to set up and operate.
The MedVac tank is part of a family of Conair downstream extrusion equipment that also includes the Medline puller/cutter. Conair also offers a microscale planetary cutter that can precision-cut rigid and semi-rigid medical tubing.
Conair is based in Cranberry Township, Pa., near Pittsburgh.

MHC Hycon debuts blow molding unit
MHC Hycon Inc. of Manchester, N.H., which has built reciprocating-screw blow molding machines since 1980, has introduced machines with 5-pound shot capacities for making industrial parts and 5-gallon containers.
Specially designed dieheads allow a range of materials to be processed, from polycarbonate to commodity resins. A clamp design allows automation for part takeout. A hydraulically powered extruder retract feature allows for quick, safe mold changes, the firm said.
MHC Hycon's standard horizontal clamp machine also is offered with a hydraulically powered extruder height feature.
Process Pilot system targets blow molding
Agr International Inc.'s Process Pilot brings closed-loop control to blow molding, with a cost-effective solution that is not specific to any brand of blow molding machine, according to the company in Butler, Pa.
Robert Cowden, Agr's chief operating officer, and Fabio Chimetto, application group manager of Nestlé Waters Europe, discussed Process Pilot during Nova-Pack earlier this year.
Agr has installed Process Pilot systems on Sidel, Krones and KHS platforms. Used with Agr's PETWall Profiler, the Process Pilot continuously monitors bottle-material-distribution and automatically adjusts machine settings.
The system can make multiple parameter adjustments to a blow molding machine simultaneously Cowden said. It can pay for itself in about a year or less, he said.
Nestlé Waters uses Process Pilot in conjunction with the PETWall Profiler system on a KHS Combi machine making 43,500 1.5-liter San Pellegrino water bottles per hour. The system was installed in October.
Nestlé Waters has realized savings in a number of areas, including scrap reduction, operator training, quality-control costs and machine maintenance. Nestlé is using Process Pilot to keep tight control of the process window as part of a major lightweighting project for San Pellegrino.
Nestlé Waters North America Inc. is in Greenwich, Conn.

American Leistriz lab adds extrusion lines
American Leistritz Extruder Corp. has installed two ZSE Maxx twin-screw extrusion lines for dryerless PET sheet production in its process laboratory in Somerville, N.J.
The extruders are tied into direct sheet extrusion. Un-dried PET pellets or regrind is metered into a co-rotating twin-screw extruder that is equipped with multistage vacuum venting. A pump, screen changer and flexible-lip sheeting die are attached to the extruder before a three-roll stack that cools and forms the PET sheet.
