This Sandretto KN 35000 is a large-format injection moulding machine — also referred to as an injection moulding press — built for the high-volume production of plastic components. Injection moulding machines of this class are used across a wide range of industries, including automotive, packaging, consumer goods, and industrial components, where molten plastic is injected under high pressure into a closed mould to produce parts with consistent geometry and surface quality. Sandretto is a well-established Italian manufacturer with a long history of producing industrial injection moulding equipment, and this machine was built in 2010 and is offered used from Portugal.
At the heart of the machine's capability is its closing force of 35,000 kN, which places it firmly in the heavy-duty large-tonnage category. The platens measure 3,360 mm × 3,060 mm, with a daylight passage between the tie bars of 2,230 mm × 2,930 mm and a tie-bar diameter of 470 mm. Mould height can be accommodated in the range of 1,000 mm to 2,200 mm, and the opening stroke extends to 2,300 mm. The machine is equipped with an ejection system delivering 550 kN of extraction force over a stroke of 600 mm. Mould weight capacity is substantial: up to 35 tonnes for fixed elements, 44,400 kg for mobile elements, and 66,600 kg total mould weight.
The injection unit is equally substantial. The screw diameter is 200 mm with an L/D ratio of 20, and the theoretical injection volume ranges from 18,000 to 36,110 cm³. The injection rate reaches 3,147 cm³/s, and maximum injection pressure is 1,670 bar. Plasticising capacity for HDPE is rated at 280 g/s, with screw speed ranging from 0 to 110 rpm and simultaneous plasticising speed up to 55 rpm. Maximum screw torque is 43,000 Nm. The barrel features six heating zones plus a nozzle, with a total heating power of 174 kW and an injection stroke of 1,600 mm.
The hydraulic system operates at 195 bar with an oil tank capacity of 8,000 litres. The machine is powered by four electric motors totalling 528 kW (4 × 132 kW), and total installed power stands at 721 kW. The no-load cycle time per the Euromap classification 54250 standard is 3.6 seconds. The machine's overall footprint is 19,135 mm × 5,550 mm × 4,440 mm, and machine weight is approximately 276 tonnes for the closing unit and 70 tonnes for the injection unit.
The listing includes a Master Mattic RB 500CN robot and an SEF 2000 control panel. The machine is located in Portugal and is available in used condition.
