Line of Products Compacted using the CNC Press

Using the CNC press, near-net or net shape compacting of products with complex shapes, which had been difficult to compact with conventional presses, has become possible.
In conventional compacting, ingenuity had been applied to die operation using tool set. However, with CNC technology, die operation is controlled by a computer, simplifying powder transfer in the die.
Because it is possible to compact parts with complex shapes in a form closer to the finished product with CNC press, machining can be reduced. Considering this and other benefits, increased application of the CNC press is expected in the future.
