Controller upgrade offered for HT press
Eurotherm Inc. is offering a retrofit Maco controller package for Van Dorn HT toggle-clamp injection presses, which no longer are being made.
Demag Plastics Group began phasing out the HT in late 2006, and stopped producing them, in Strongsville, Ohio, in 2007.
The HT has an installed base of about 8,000 presses in North America.
Eurotherm of Leesburg, Va., said the package is compatible with the HT operating system, but offers an upgrade to deliver more precise and consistent temperature control.

New trench welder comes in 3 models
Georg Fischer Piping Systems Ltd. has developed a butt fusion machine for use in the field, called TM for trench machine.
Extra features on the three new models include knurled handles, a flange-adapter clamping unit, angled upper clamps and a set of reduction clamp inserts.
The top line of the welders includes a hydraulic power unit. The Eco line features a lightweight, open hydraulic unit. WR models come equipped with a date-recording device.
Georg Fischer is based in Schaffhausen, Switzerland.

St.-Gobain provides SIP testing for hoses
Saint-Gobain Performance Plastics Corp. in Aurora, Ohio, has introduced a steam-in-place testing service for its hose assemblies.
The company manufactures a full line of hose assemblies for silicone- and fluoropolymer-lined hoses for pharmaceutical and biotech uses.
During SIP sterilization, hoses are exposed to severe conditions that can adversely affect the product's service life. Now Saint-Gobain Performance Plastics can run those tests on automated equipment, reproducing methods that customers use on their production lines.

R&B integrates PLCs with motion control
R&B Plastics Machinery LLC of Saline, Mich., has integrated the motion controls for its blow molding machines, including parison control, into off-the-shelf Siemens programmable logic controllers.
R&B had been using closed-loop hydraulic motions with dedicated-motion control cards, which Atlanta-based Siemens Energy and Automation Inc. said are expensive and somewhat difficult to coordinate with programming.
A standard Siemens S-7 PLC controls the motion control function, which handles the positioning of hydraulically actuated components. For example, one R&B machine has nine axes of servohydraulics three for parison control and six for motion control. The machine has two shuttles, two molds and two blow pins.
The first of the motions that R&D tried to manage through the plc was the parison. Normally, blow molding machines are controlled by a machine controller with a separate, dedicated independent parison programming unit with a dedicated-motion control card; or by personal-computer-based automation using proprietary code to handle motion control.
But R&B wanted to integrate parison programming in the main machine controller, which was possible using the PLC.
Next, R&B integrated the rest of the servohydraulic axes into the PLC. Another function the PLC runs is camming of the blow pins with the carriages.
The PLC also is managing more than 30 zones of heat control from the hopper to the extruders, and through to the parison head, the company said.

Rampf to produce PU gaskets in US
Rampf Group Inc., which has handled sales and distribution of its German parent's polyurethane mixing and dispensing equipment, is producing liquid materials for foam gaskets in Wixom, Mich.
Wixon-based Rampf is the U.S. subsidiary of Rampf Group of Grafenberg, Germany. The firm has invested $1 million to build a 30,000-square-foot plant in Wixom to make PU foam gaskets. The materials mainly are used by the auto industry for sealing doors.
Also, Rampf is offering a new two-component mix head, called MS-C, featuring a patented, servo-driven ceramic valve system. The valve disk has no dynamic seals, so valves do not require frequent cleaning and rebuilding.
Valve and mixing sections are separate, so the mixing chamber and mixer can drop down with a quick coupler for a rapid change.

Cheaper Magic line assembled in Europe
Magic MP SpA of Monza, Italy, introduced the UE hybrid series of economical continuous extrusion blow molding machines.
Magic said UE is designed to counter the high cost of the euro, yet still offer a blow molding machine made entirely in Europe. The line uses the same components as Magic's IB hybrid line, at a significantly lower price.
The firm is offering five UE models, in both single- and double-station setups, to make containers from 15 ounces to 1.3 gallons. Magic also is selling a long-stroke model, the XL.
The UE has a Siemens controller, with a color monitor.
Ferruccio Giacobbe, Magic's owner and general manager, said firm decided to look for production savings inside Europe, rather than move production offshore and risk losing control over proprietary designs, such as its mechanism for electrically driven linear-movement mold transfer.
The solution, Giacobbe said, was to subcontract out some of the machine parts and subassemblies to smaller, trusted machinery firms in Europe. Magic does final assembly and testing of the UE machines at its factory.
Magic continues to produce all of its IB line and its fully electric EP and ME machines, in Monza.
Magic's U.S. sales office is in Ellwood, N.J.
