case study

Marking pacemakers using laser annealing technology

The client is a medical device manufacturer looking to integrate a marking system into its high-speed production line, while producing a mark that does not damage the product’s corrosion protection.

Operation of the machine:

The cobot automatically loads and unloads the parts to perform laser marking.
A sensor detects the presence of a part, the laser marks it, then a camera reads the Data Matrix code and the alphanumeric characters.

The challenge

A rotating plate loader combined with a cobot enables the cycle time of less than 60s required by the client to be achieved.

The use of several loading pallets and a rotating plate facilitates continuous working to increase productivity.
Checking the presence of parts and the reading of marking enables the quality of markings to be guaranteed.
As a result, the marking content, in particular the serial number and the 2D code, can be tracked throughout the product’s life.

The SIC MARKING
solution

SIC MARKING provided the client with the laser marking station for the pacemaker with high-end laser marking equipment.
The aim is to perform high-contrast marking, while respecting the surface finish of the pacemaker’s titanium alloy housing.

This marking, known as annealing, enables high-contrast black marking to be produced on the grey titanium alloy surface without damaging or weakening the material.
As a result, corrosion protection is preserved for the product’s future life.
