Lectro's MTM boasts fast take-away system
MTM Systems, a division of St. Louis-based Lectro Engineering Co., said its MTM 2006 high-speed servodriven take-away system is designed for Aoki and Nissei ASB blow molding machines.
The 2006 is capable of nine-second cycles for dual-row cavitation setups. The servodrive provides accurate drops, reducing downtime and improving productivity, MTM said.
An ionization blower, for eliminating static buildup, comes standard. The vacuum conveyor will run in reserve. A blow-off station clears preforms, allowing for quick startups.
The portable equipment can be moved from one blow molding machine to another.

N.J. extruder maker touts compact unit
Officials at Boston Matthews Inc. boast that their new extruders are compact and easy to position.
The multilayer extruder line, called Jockey, can be used in any extrusion environment.
Norwood, N.J.-based Boston Matthews used computer design software to create Jockey. It can accommodate up to five extruders and additional production equipment. A smaller cluster of extruders allows the other equipment to integrate easily into the total line with little disruption and loss of floor space.
Standard features include an alternating-current motor with encoder feedback and a flux vector drive with forced ventilation, which cuts energy costs. It can shut down some features, such as the ventilation fans, when they are not required.
Extruder maker Boston Matthews said it has provided several turnkey Jockey lines for applications such as cross-linked polyethylene pipe and automotive and cosmetic tubing.
All electrical components are fitted with plugs and sockets, so the operator can quickly change thermocouples, heaters and fans without having to call in an electrician.

Cincinnati Extrusion offers giant extruder
Cincinnati Extrusion GmbH of Vienna, Austria, has shipped what it claims is the largest parallel counter-rotating, twin-screw extruder ever built for an American customer that makes PVC sheet.
The giant machine, an Argos 173, can turn out 4,400 pounds of material an hour. Cincinnati Extrusion said the machine is more than one-third bigger than what had been its largest parallel twin-screw extruder, the Argos 135. The unit measures 31 feet long.
The Argos 173 can make PVC foam sheet up to 1.22 inches thick.
In other news, about 200 people from 35 countries attended a conference on hot-water pipe manufacturing, held at Cincinnati Extrusion headquarters in December. The company has four pipe extrusion lines in its technical laboratory in Vienna.
Cincinnati Extrusion also announced it has blocked an extruder technology patent by competitor Milacron Inc. Cincinnati Extrusion filed formal opposition against the European patent of Milacron Inc., which sought a patent for what the Austrian company claims is an already-existing extruder technology.
The European patent office revoked Milacron's patent, according to Cincinnati Extrusion.
Officials of Milacron did not respond to a request for comment.
Cincinnati Extrusion's U.S. unit is in Erlanger, Ky.

Corelco corrugators target auto tubing
French extrusion equipment supplier Corelco has developed a range of vacuum corrugators for making automotive lines for carrying fuel, oil, air and water.
The corrugators can produce automotive tubing, up to 2 inches in diameter, in three ways: a sequential mode for running different thicknesses, variable length, and vacuum forming extrusion.
In sequential mode, mold-block speed is increased or decreased according to diameter, to match the required thickness. This process can produce complex pipes, with different patterns or diameters, and either constant or variable thickness.
Corelco is based in Manziat, France.

Side-fed die handles specialty materials
A side-fed, multilayer die from Battenfeld Extrusionstechnik GmbH allows the extrusion of materials with high residence time and temperatures, even at low-mass flow rates, and ensures accurate wall-thickness distribution.
Materials with special barrier, optical, mechanical or thermal properties are in demand for plastic pipes. But often, those types of materials are highly sensitive to thermal and mechanical stress. Battenfeld said with conventional dies, such as spiral mandrel dies, these materials cannot be processed.
Battenfeld's side-fed die allows an optimal melt distribution into a circular ring geometry, for further distribution in a short period of time. A coat-hanger manifold, followed by a geometry of twin center sleeves, ensures symmetrical distribution of pressure inside the die, for automatic centering of the mandrel.
Battenfeld Extrusionstechnik is based in Bad Oeynhausen, Germany.
