HPM, rejuvenated as a division of Taylor's Industrial Services LLC, is back and the 126-year-old firm is offering something brand new - a rotating, movable platen that swings out 180 degrees.
Officials of HPM (Booth N5507) claim the two-platen Freedom Rotator 1100-WP is the world's first to use that design. They are pitching the technology for multicolor, coinjection, insert molding and other markets getting a lot of press these days.
``While there are other techniques for insert molding applications, no other machine uses a rotating, moveable platen like what the HPM Division has developed for the Freedom series,'' said Gerry Sposato, director of sales and marketing.
Global patents are pending.
In other NPE news, HPM announced it is offering an optional electric screw drive on the Freedom, rolling out a new line of toggle presses called the GP Plus and showcasing Prodex single-screw extruders. The HPM Division also announced it has signed a machine controls agreement with Siemens Energy & Automation for its machinery.
The Rotator is not just a rotating die, said Ken Eichhorn, engineering director. The actual platen turns.
``What makes the Rotator unique is that the moving platen rotates on its center,'' he said. The platen sits on a hydraulic-driven bearing system.
``This allows the platen's back side to be available so the cured part can be removed by a robot, and films and inserts can be inserted into the die while another part is being molded,'' Eichhorn said.
One key market is automotive, where HPM is promoting the rotating platen on large-ton presses. HPM developed the Rotator option for its Freedom series for an automotive customer molding bumper fascia. Sposato said the machinery maker also has received interest from nonautomotive customers, including housewares and appliance molders.
The Freedom hydromechanical presses are available in clamping forces of 360-5,000 tons.
HPM, which hit a low point when it closed down for several weeks in 2001, hopes to cement its comeback at NPE 2003.
Taylor's Industrial Services of Tinton Falls, N.J., bought the assets of HPM Corp. in mid-2001, just before HPM filed for liquidation under Chapter 7 bankruptcy. HPM brings Taylor's a strong heritage. It was founded in 1877 in Mount Gilead, Ohio, to make apple presses. HPM made some early injection molding machines in the 1930s.
Now the company employs 160. It continues to make the complete product range of injection presses, extruders and die-casting machines.
The Freedom series is a redesigned version of the old Next Wave presses. Those machines pioneered a retractable tie-bar system that pulls the tie bar back when the mold opens, allowing complete access to the mold for part removal. Now, that design also gets the tie bars out of the way so the platen can turn 180 degrees.
The Rotator can shorten cycle time by 30-35 percent and greatly improve productivity, HPM said.
HPM is calling the Freedom model with an electric screw drive the Freedom Hybrid. The company claims the press uses 30 percent less energy compared with the same size of a nonhybrid Freedom. The electric screw drive is available on any Freedom-series press, including the Rotator.
Also new from HPM is the GP Plus toggle press. Plus machines are a step up from HPM's GP series, first introduced in 1999 as the Universal. Under the new ownership, the company added the GP as a stripped-down, lower-price version of the Universal.
``The GP Plus is designed for molders who don't need a lot of bells and whistles, but still need a machine that offers flexibility and allows the molder to be price-competitive in their markets,'' said Gary Edington, sales manager for toggle machines.
GP Plus machines come in clamping forces of 90-900 tons. Standard features include two pumps for simultaneous functions, an improved toggle design, larger tie-bar spacing, better rigidity of the ejector cylinder support and platens and an improved controller, the company said. GP Plus machines come with a Barber-Colman Command 4000, a 10-stage, closed-loop injection speed control.
In extrusion, HPM will display a Prodex machine for running small tubing, profiles, pipe and compounding. It has a new Siemens Siject 16 touch-screen controller. The higher-end extruder, Prodex Plus, often is used in sheet lines.
HPM also will show a horizontal roll stack for sheet, called the HGL-2. It is designed for sheet with a high-quality surface, such as for glass replacement.
Turning back to injection molding, HPM gave more details about its relationship with Siemens, which developed the Total Command 2003 (TC03) exclusively for HPM. The controller is used on the company's Freedom hydromechanical presses and all Modular hydraulic machines.
Christopher Filos, president and chief executive officer of Taylor's Industrial, said that although HPM wanted a global control platform, ``we didn't want it so proprietary that a customer couldn't find a spare part anywhere in the world.''
Siemens began working with HPM and Filos in early 2002.
Features of the TC03 include flexible screen sets that can be customized to plant needs, easy integration into current information-management systems, the ability to connect with other third-party machines and robots, and built-in maintenance and troubleshooting. It has one of the industry's fastest processing speeds, the companies said.
In people news, HPM has hired Dean Francis for the newly created position of vice president of global development, initially focusing on HPM's die-casting machines. Before joining HPM, Francis was president of a consulting firm for small and midsize industrial businesses, as well as serving as chairman of Great Lakes Die Casting. Before that, he was president of IdraPrince, a major die-casting equipment maker, and worked for AlliedSignal Inc.'s Specialty Chemicals unit, Johnson & Johnson's Ethicon Endo-Surgery Division and GE Plastics.
Francis also will oversee global development of HPM's injection molding and extrusion machinery lines.
Customer service is a core value at the HPM Division, according to Filos and his brother Joe Filos, vice president of Taylor's Industrial.
``Joe and I have taken those after-hours calls and have driven parts to customers,'' Christopher Filos said. ``From the new hire on the floor to my office, every member of Taylor's HPM has one purpose: to be everything our customers need us to be.''
Taylor's Support Services is a stand-alone business unit within Taylor's, run by John Beary as general manager. Beary was vice president of manufacturing at the former HPM in the late 1990s and joined Taylor's to run TSS in February 2002.
