This Sandretto 515-135 Serie is a used injection moulding machine — sometimes referred to as an injection moulding press — dating from 1985 and currently located in Portugal. Injection moulding machines are used to manufacture plastic parts by injecting molten material under high pressure into a mould, and they are fundamental to industries ranging from automotive and consumer goods to packaging and electronics. Sandretto is a well-established Italian manufacturer with a long history of producing injection moulding equipment, and the brand is widely recognised across the plastics processing industry.
The machine operates with a clamping force of 135 tonnes, delivered through a toggle clamping system — a lever-type closure arrangement valued for its speed and energy efficiency during the clamping phase. The tie-bar spacing measures 470 × 470 mm, with a column spacing of 1,120 × 1,120 mm, and the minimum mould height is 275 mm. The opening stroke is 575 mm, giving a practical indication of the mould sizes and part geometries this machine can accommodate.
On the injection side, the screw diameter is 35 mm as standard, with 40 mm and 50 mm alternatives also available. Shot volume is 139 cm³, with a shot weight of 117–166 g measured in polystyrene depending on configuration. The estimated injection volume of the plasticising unit is stated at approximately 6,220 cm³ (around 6.2 litres), and injection pressure reaches up to 2,500 bar — a high-pressure capability suited to demanding moulding applications requiring fine detail or difficult materials.
Power is provided by a pump motor rated at 48 kW, within a total installed power of 158 kW. The machine is equipped with a SELEC 90 CNC control system, which handles process management and cycle control. A Euromap-12 interface is available, enabling connection to robotic handling systems, and the seller notes compatibility with additional options including hot-runner systems and further automation equipment. The machine weighs approximately 4,500 kg.
This is a used machine from 1985, and the seller advises that the specifications presented may differ from actual values; physical inspection of the equipment is recommended to verify all characteristics.
