DUSSELDORF, GERMANY-Improved clamping and injection units were shown by Dr. Boy GmbH, which makes small injection molding machines. The Boy 25 features a canti-levered injection unit. On the clamping end, the moving platen is carried by four piston rods that double as tie bars. Regular lubrication of the tie bar bearings is not necessary because they are located within the hydraulic cylinder. The press also boasts good access for parts removal.
The Boy 25 also can use the smaller injection unit for the Boy 22, giving the molder greater flexibility, the company said.
The clamping system on the Boy 50 machine has been improved, to be quicker in travel movements, pressure buildup and reduction.
Boy said it is making its machines smaller and quieter.
At its booth, Boy also demonstrated two-component molding by linking two standard machines to a robot.
Boy Machines, the company's North American headquarters, is based in Exton, Pa.
