Automation for the future


The Customer:

Ypsomed AG, Switzerland, with around 1,000 employees makes products and components for medical technology applications. Already one of the biggest plastics processors in Switzerland, Ypsomed AG has in recent months invested in a further expansion of production capacity at the Solothurn plant, which produces different types of injection pen.

The Task:

Install and commission a new work cell for production and quality control of ampoules for drug delivery.

The Challenge:

Insulin pens are a high-spec product and the customer needed a production system that would guarantee product quality and a high level of "lights out" operation.

The Solution:

Working in close collaboration with KM Automation, another company in the KMK Group, we planned and installed a work cell consisting of a KM 200-700 C2 with 2000 kN (200 t) clamp force and a fully automated parts handling system. The ampoules are injection moulded in an 8-cavity mould with a cycle time of 15 seconds. An LR150 linear robot demoulds the parts, which are placed via a transfer system in a rack on a conveyor belt. They then move through the optical and mechanical inspections.

The Outcome:

KraussMaffei supplied the whole work cell except for the mould and the temperature control units. We installed and commissioned the whole system on the customerís behalf. The work cell footprint was successfully limited to just 22m≤. The injection machine software coordinates operation of all components in the whole system. Each injection cycle produces eight parts, but the workpiece rack can accommodate 12 parts per row, so that it also functions as a buffer for the robot operation. The parallel 100% quality checks mean that only OK parts leave the work cell. This cuts the need for downstream quality inspections to a routine minimum. With this advanced technology up and running, Ypsomed can continue to expand its market position.
