Manufacturing process explained on a demonstration marble run

The part shown in the upper left image was created for demonstrational purposes. It contains a 3.4m long channel (18x18mm) serving as a marble run as well as an embedded copper component which, by milled out openings, shows HERMLE's company logo.
Part dimensions: 520 x 520 x 140 mm, total weight approx. 270kg, of which about 40kg where applied with MPA technology.

The image sequence illustrates the main steps of the manufacturing process:

  1. Milling of the marble run channel into the prepared blank.
  2. Filling of the channel with a water-soluble filling material.
  3. Application of a layer of 1.2344 hot-working steel. Milling of the copper component contours.
  4. Application of pure copper onto the pre-milled surface and subsequent milling of the copper part's shape.
  5. Application of a second layer of 1.2344 steel. Milling of the copper inlay openings and dissolving of the remaining filling material in the channel.
