The Customer:

LEONHARD KURZ Stiftung & Co. KG in Fürth, Germany, is a global supplier of hot stamping foils and foil-based products.

The Task:

Manufacturing display lenses for mobile phones

The Problem:

In-mould decoration in a very small cleanroom

The Solution:

The IR 30 I, the smallest KraussMaffei industrial robot, is integrated inside the injection moulding machine's safety housing. This keeps the cleanroom small enough to be implemented using only one laminar-flow box above the machine.

The Outcome:

Mechanically integrated the IR 30 I unloads the IMD parts from a KM 80-180 CX. The in-mould decorating (IMD) process uses a film that is unwound through the mould. It is back injected in the mould. Also integrated in the housing is a conveyor belt on which the moulded part is deposited and conveyed out of the machine area. The objective of this new development was to design a compact production cell. The robot and the handling system are factory tested and shipped together with the machine. Due to this, the installation of the whole production cell at the customer can be realized very quickly. The effective mechanical integration makes the production cell extremely cost-competitive. Programming the KraussMaffei operator interface is simple, because the robot function buttons can be integrated in the machine operator panel.
