This listing is for a used injection moulding machine — sometimes referred to as an injection moulding press — manufactured by Sandretto, a long-established Italian builder of plastics processing equipment widely used in automotive, packaging, consumer goods, and industrial component manufacturing. The machine is a Sandretto 612-150 Serie, dating from 1991, and is currently located in Portugal.
Injection moulding machines of this type work by melting thermoplastic material and injecting it under high pressure into a closed mould, where it cools and solidifies into the finished part. The key performance parameters are well documented for this unit. Clamping force is rated at 150 metric tons, with a tie-bar spacing of 470 × 470 mm and a column spacing of 460 × 460 mm. The platen accepts moulds between 155 mm and 560 mm in thickness, with a minimum mould height of 275 mm, and the opening stroke is 575 mm. The stage dimensions measure 690 × 690 mm.
On the injection side, the screw diameter is 35 mm — with some units available in 40 mm or 50 mm — and the screw length-to-diameter ratio is 21:1. Injection volume is 139 cm³ per shot, and shot weight is given as 117 to 166 g for polystyrene. Injection pressure reaches up to 2,500 bar, and estimated barrel capacity is approximately 6,220 cm³. The control system is Sandretto's own SeLogica CNC platform, which provides programmable process control for injection speed, pressure, and mould parameters.
Power is provided by a pump motor rated at 48 kW, with a total installed power figure of 158 kW. The machine's overall footprint is approximately 6.36 × 2.08 × 1.50 metres, and weight is listed at approximately 7,000 kg, though a separate figure of 4,500 kg also appears in the seller's notes and should be verified on inspection.
The machine is equipped with a Euromap 12 interface for robot integration, and a Euromap 32 robotic interface is also referenced; additional options noted include hot-runner compatibility and further automation connectivity. As is standard practice with used machinery of this age, all specifications should be confirmed by physical inspection of the equipment prior to purchase.
