Automatic description (AI-Generated)

This listing is for a Weber DS-85 twin-screw extruder, designed for processing PVC-hard profiles. Manufactured in 1979, the machine features parallel twin screws with a diameter of 85 mm each. The extruder has a screw length of approximately 17 times the diameter, optimized for effective extrusion. It offers a maximum screw speed of around 30 rpm and a screw torque of 10,000 Nm. The motor power ranges between 3.8 and 23.0 kW, driven by a commutator motor from Elektra Faurndau.

The extruder is equipped with four heating and two cooling zones in the cylinder, using air cooling with a fan, plus eight heating zones for the tool. Temperature control is managed by 12 digital PMA KS40 controllers. Additional accessories include a mass pressure sensor and a mass temperature sensor. The connected load is approximately 60 kW without the tool.

It has an extrusion height of 1100 mm and an output capacity of about 150 kg/h, suitable for PVC-hard profiles. The machine comes with a material hopper and connection flange, as well as a vacuum pump rated at 1.1 kW, including a material separator. Its dimensions are 4500 mm in length, 1200 mm in width, and 2100 mm in height, with a total weight of around 4000 kg.

The electrical control cabinet was completely renewed approximately three years ago, with the extruder having operated for only 216 hours since then. The machine was repainted in light gray (RAL 7035) and has been checked for functionality.

From the images, this twin-screw extruder is in good physical condition, appearing clean and well-maintained with no visible damage or rust. It features a large material hopper on top for feeding, a side-mounted control panel with multiple digital displays, analog meters, and labeled switches, offering comprehensive operational control. Emergency stop buttons and ventilation grilles are visible on the side panels. The rear view shows intact and clean mechanical components and motor assemblies, with exposed motor and piping beneath the machine frame.
