Case Study NETCore® – Flange

From Production Manager Thomas Zander, GSF FOUNDRY STASSFURT | March 12, 2020

Customer opinion

Problem: Due to the size of the pendulum, knocking off the risers with a 150-mm feeder neck is hardly possible. In addition, there is the risk of breaking into the casting when knocking off. The foundry must remove the part from the regular process and remove the feeder mechanically in an additional step.

Challange: Removal from the feeder neck in the regular process without transferring the part to an additional workstation.

Customer

GSF foundry Staßfurt

Cast part

Flange

Material

EN-GJS 500-7

Weight

7.900 kg

Moulding method

hand moulded

Power supply technology

ZXF 15 B250N

Solution

Integrate NETCore® technology B 550-250 N80 in the riser neck

Result

By using NETCore® technology, the casting can be produced in the regular process and enables the foundry to reduce the machining time by 300 minutes per casting. The contact residue can be removed by mechanical means (light grinding). In addition, the risk of rejects due to break-in is eliminated.
