Main Product Description

Used 2007 BOY Model 55A hydraulic plastic injection molding machine manufactured by Dr. Boy GmbH & Co. KG, Germany, previously operated in an ISO 13485-certified medical device manufacturing facility. This compact four-tie-bar injection molding press provides 550 kN of clamping force (approximately 55 metric tons or 60.6 US tons), with 360 x 335 mm tie-bar spacing and 565 x 540 mm platens. Manufacturer specifications indicate a maximum mold opening stroke of 400 mm, minimum mold height of 250 mm, maximum daylight opening of 650 mm, and standard ejector stroke of 80 mm. The machine features an enclosed molding area, safety guarding, operator control panel with display and keypad, top-mounted stainless steel material hopper, hydraulic drive system, and integrated electrical cabinet. Nameplate electrical requirements are 230V, 60 Hz, three-phase, 61.9 amps, with maximum hydraulic pressure of 180 bar. Manufacturer injection unit options include 28, 32, 38, and 42 mm screw diameters, with theoretical shot capacities of 73.9–166.3 cm³ and maximum polystyrene shot weights of 67–150 grams, depending on screw configuration; the installed screw size has not been confirmed. Serial number 59383. Suitable for precision thermoplastic molding, prototype development, medical device components, and small- to medium-volume plastics production.
