This Sumitomo SHI Demag Systec SP 350 is a hydraulic injection moulding machine — sometimes referred to as an injection molding press — used for the precision processing of plastic components by injecting molten material into a mould under controlled pressure. Sumitomo SHI Demag is a well-established manufacturer of injection moulding machinery, supplying equipment to industries including automotive, packaging, medical, and consumer goods. This machine was built in 2015, is offered in used condition, and is currently located in Germany.
The machine is equipped with a 45 mm screw diameter and accepts moulds with a minimum height of 350 mm and a maximum height of 745 mm. The mould connection dimensions follow the EUROMAP March 1996 standard, with a centring diameter of 160 mm on both the fixed and moving platens. The moving mould mounting platen is supported via linear guides, and position measurement throughout the machine — covering injection, mould, and ejector movement — is handled by a digital, wear-free system using ultrasound and high-resolution rotary encoders. Electrical supply is three-phase 400 V ±10% at 50 Hz, with separate mains connections for the drive and heating circuits. The pump drive delivers 59.0 kW, and a reinforced oil cooler accommodates cooling water supply temperatures up to 35 °C. Mould cooling water and machine cooling water connections are kept separate.
The clamping unit features a four-stage mould closing and four-stage mould opening sequence, toggle lever oil lubrication, and an ejector with position control that allows pressure, force, and velocity to be programmed independently and operated in parallel with mould movement. Active mould protection via sensor during closing is included, along with clamping force control and a manually adjustable monitoring switch for the mould open position. A central grease lubrication system is fitted.
Among the optional equipment installed, the machine includes a speed-controlled servo pump drive (activeDrive), a separate ultra-fine bypass filter unit (activeCool&Clean), and an individual axis movement optimisation system (activeAdjust). Hot runner control is integrated for 12 zones at 2.75 kW, with an additional pneumatic hot runner nozzle control via a 5/2-way valve. Pneumatic equipment includes 6 programmable 5/2-way valves on the movable tool plate and 6 on the fixed tool plate, served by a central maintenance unit. A core pull 1-circuit is fitted with proportional valve control, non-return valves, and a manual pressure relief. Holding pressure switchover operates dependent on hydraulic pressure with pressure recording, and nozzle contact pressure when the mould is open is programmable. Nozzle movement can run parallel to the closing movement.
A cooling water manifold with 2 × 8-way distribution is mounted on both the fixed and movable platens, using G1/2" internal thread ball valve connections and rated for a maximum flow rate of 17 m³/h at 60 °C and 8 bar. Additional installed equipment includes a material hopper with automatic filling and a hopper shut-off with emptying option, two freely programmable operator screens, a flashing light, an emergency stop switch on the operator side, and a Schuko socket (230 V / 10 A) as well as an IECEE three-phase 400 V / 16 A socket, both switchable via the main switch. A Fanuc robot is included with the machine. The paint finish is deep black (RAL 9005) on the machine bed and lower switch cabinet, with signal white (RAL 9003) on the clamping unit, injection unit, safety doors, fixed safety devices, and upper switch cabinet.
