Blow molding machinery manufacturer Graham Engineering Corp. has entered a new business — running a pultrusion operation at its York factory.
Graham Engineering has started by pultruding glass-fiber-reinforced window profiles for Graham Architectural Products, a sister company in York that makes commercial and architectural windows. Both companies are owned by Graham Group.
Graham Architectural Products markets the pultruded windows as GThurm, touting what it said is its superior strength and energy efficiency because of good insulating properties. The window company said the manufacturing process, dubbed G2RP, features 80 percent continuous-strand glass reinforcement with 20 percent polyurethane, a much-higher content of glass than traditional pultrusions.
Graham Engineering President Wolfgang Liebertz said the machinery firm is capable of building the pultrusion equipment, but in this case it did not.
He declined to say how many pultrusion lines are running in York or to give details about the equipment.
During a June 15 interview at Graham Engineering's York headquarters, Liebertz said Graham Engineering wants to become a broad-line pultruder, serving more than the window market.
“We are pultruding here,” he said. “We are producing lineals for the window industry now, but overall we are going to be producing for other markets.”
Graham Engineering has taken out help-wanted ads seeking a sales manager and a machinery processing technician for its new pultrusion operation.
According to literature marketing GThurm windows, Graham Architectural Products worked with Graham Engineering and Bayer MaterialScience LLC to develop the manufacturing process.
