This Arburg 420C is a used injection molding machine — sometimes referred to as a plastic injection press — built in 2003 and currently held in a warehouse in Hannover, Germany. Injection molding machines are used to manufacture plastic parts by injecting molten material into a mold under high pressure, and Arburg is one of the most well-established names in this field, producing precision injection molding equipment for industries ranging from automotive and medical technology to consumer goods and electronics.
What distinguishes this particular machine is its three-component (3K) configuration, making it capable of processing up to three different materials or colours in a single production cycle. The three injection units are arranged in a combination of orientations: one horizontal, one vertical, and one in an L-position, the latter fitted with a protective housing. The machine can also be operated as a standard two-component (2K) machine, with the third injection unit deactivated as needed. It does not include a turntable. The control system is Arburg's Selogica, and the machine has logged 21,200 operating hours.
The clamping unit delivers a clamping force of 1,000 kN. The tie bar distance is 420 × 420 mm, with a platen size of 795 × 795 mm. Maximum distance between platens is 950 mm, minimum tool height is 300 mm, and the ejector stroke is 225 mm with a force of 66 kN.
The first injection unit (150 unit) features a 15 mm screw in a high wear-resistant design with a fixed shut-off, an injection volume of 17 cc, a shot weight of 15 g, and a maximum injection pressure of 2,750 bar. The second injection unit (also a 150 unit) shares the same screw diameter, injection volume, shot weight, and maximum injection pressure of 2,750 bar. The third injection unit (60 unit), mounted in the L-position for horizontal injection into the mold parting line, likewise uses a 15 mm screw and delivers 17 cc injection volume and 15 g shot weight, but operates at a maximum injection pressure of 2,080 bar.
The machine is equipped with Technology Level 2, which provides a servo-controlled hydraulic system with two control pumps. This enables path-dependent, controlled target ramps, programmable and servo-controlled mold clamping force build-up via a second pump, programmable nozzle contact force, and simultaneous movements of the nozzle, ejector, and optional core pullers, including an extended travel movements package. Technology Level 3 is also fitted, adding a third control pump for simultaneous movement of the main axes and faster movement of the secondary axes — a prerequisite for the hydraulic system serving the second injection unit.
Additional equipment includes a vertical injection unit mounted on carriers in place of clamping tie bars for the second injection component, with a manually operated working position adjustable between 70 and 250 mm; position-controlled screws with control valves and controlled back pressure for both the first and second injection units; a position-controlled screw for the third injection unit; a 15 mm plasticizing barrel set in highly wear-resistant design with advanced feed and pressure-reducing valve; open nozzles for both the primary and L-position units; a nozzle tip with 15 mm radius for the L-position; heating tapes for the open nozzles; and two core pulls. The machine runs on 400 V / 50 Hz and is available immediately from the seller's warehouse in Hannover.
