Vertical machines

Number one for ergonomic efficiency

Ergonomic efficiency is a top priority with our vertical ALLROUNDER injection moulding machines. You can use these machines for the efficient overmoulding of inserts. Our videos show the broad range, from automated machine concepts through to customer-specific special solutions.

Dilatator

Automated production of medical parts
The turnkey solution for the automated overmoulding of medical components satisfies Class 8 clean room conditions (ISO 14644). The use of the production cell has enabled significantly increased unit volumes and lower reject numbers.

The system is centred around a vertical ALLROUNDER 275 V. A six-axis robotic system handles the operations that were previously performed manually: monitored by a camera, it places four dilator tubes on each mould insert, positions the latter in a 4-cavity mould, removes the parts once they have been overmoulded with PE, separates the sprue and sets down the finished tubes on a conveyor belt. A complete cycle takes 15 s.

A synchronised trio

Turnkey solution for automatic Start/Stop system in cars
In the automated production of automotive parts, all handling is performed by three six-axis robotic systems. An “event-driven rotation” function replaces a rotary unit for part orientation. The robots move in synchronisation with the machine in the working area.

At the heart of the production cell is a vertical ALLROUNDER 375 V with 4-cavity mould, with the three robots integrated in its SELOGICA control system. The component – a connector carrier for the automatic Stop/Start system in cars – comprises a metal insert and two pin contacts, which are overmoulded with fibre-glass reinforced PBT. The inserts are supplied by a tray feed and a feeder cell featuring a Scara robot. The robots are responsible for aligning and inserting the components in the mould, removing the finished parts and performing a 100% camera inspection. In this way, around 3,000 complete components are produced in just one shift.

Overmoulding of cables

High flexibility in the most confined of spaces
For the automatic overmoulding of inserts, a compact production cell around a vertical ALLROUNDER 375 V is used. Handling of the flexible cables is performed by a six-axis robotic system. Manual preparation and insertion are rendered superfluous.

On the system, cables of differing lengths are inserted and overmoulded fully-automatically in several cavities, at different positions on a 4-cavity mould. The system is characterised by great flexibility, short cycle times and a high level of availability. Highlights of this application include the versatile handling of flexible parts and the six-axis robotic system featuring the SELOGICA user interface and direct connection to the machine control system.

Reel-to-reel

Reel-to-reel process
Leadframes can be overmoulded with plastic using the reel-to-reel process. For the production of clips, a vertical injection moulding machine is equipped with a combination mould, which separates the finished parts from the carrier strip. The process impresses with short cycle times of 30 s and continuously high quality.

The incorporation of several processing steps, the automated production system built around a vertical ALLROUNDER 275 V is extremely cost-efficient. The stamped parts are unwound from the reel by a horizontal pay-off mechanism. The pre-stamped strip with the clip blanks is fed into the injection moulding machine and overmoulded with plastic. In the second step, the finished clip is separated while the next clip is being overmoulded. The finished parts fall onto a conveyor belt via a chute.
