CHICAGO—Injection press builder Engel North America (Booth S2382) is showing its big, 2,000-ton Duo two-platen injection molding machine, a new clamp linkage for tie-barless machines with no moving parts and a new side-entry robot. Engel has sold more than 6,000 tie-barless machines since it introduced tie-barless technology in 1989. Engel has now expanded the range of clamping force on its tie-barless machines, to 40, 60, 100, 150 and 200 tons.
Engel's new patented clamp linkage for tie-barless presses will be standard on its newly produced machines. It also makes the ejector system more accessible and compatible with standards set by the Society of the Plastics Industry Inc., Engel said.
Engel's new side-entry robot, the ERSE, is compact, for handling small to medium-sized parts where no vertical stroke is required. The robot can handle payloads weighing as much as 10 pounds.
Engel has sold 100 of its Duo two-platen machines since introducing them in 1994. The space-saving machines come in clamping forces of 1,250-4,000 tons. Engel is building them in York, Pa. Duo machines have a hydromechanical clamping system.
Engel recently sold its 100th two-platen press to a General Motors Corp. factory in Brazil molding car bumpers. The 2,300-ton machine was shipped with an Engel ERC robot to the General Motors do Brasil in São José Dos Campos, Brazil, according to Engel's sales representative for Brazil, Herbert Buschle. The machine was made at Engel's factory in St. Valentin, Austria.
Engel North America also announced it has extended its Duo line to 6,000 tons, from a previous high of 5,000 tons. The first 6,000-ton Duo ever built was sold recently, to CAPP-Plast in Florence, Italy. CAPP-Plast will begin molding large industrial and agricultural containers in June 1998.
The popularity of two-platen presses is evident this week in McCormick Place. At least four machinery makers — Husky Injection Molding Systems Ltd., Cincinnati Milacron Inc., HPM Corp. and Van Dorn Demag Corp. — are showing two-platen machines for the first time.
