The choice of material for the jaws had to be suitable for a small production run without causing excessive wear above 500 cycles.

SAPRENA provided Lynxter with the desired hardnesses and STL files of the jaws. Lynxter choose a RTV2 40Sh industrial grade silicone to print the new jaws. This silicone has good strength and durability while providing the required hardness demand.

The parts were rushed to the site to be set up and tested directly on the production line.

After its installation on the line, the result was very conclusive, and SAPRENA was able to proceed with the validation of the new jaws.

Lynxter enabled SAPRENA to maintain production by printing non-slip silicone grips in less than 72 hours.

By using 3D printing, SAPRENA has been very reactive and has avoided delivery delays and production overruns by quickly replacing worn parts using 3D printing.

Completed in June 2022, the parts are still in place on the production line and have been used to produce the packaging of more than 20,000 containers to date.

This experience has also enabled SAPRENA to see the qualities of industrial silicone (resistance, hardness, durability) and its benefits to minimize the wear and tear of certain production tools. 3D silicone printing is a long-lasting solution that increases the lifespan of wear parts.

This case perfectly illustrates how adopting 3D printing offers a new autonomy, increases quality, saves time and consequently brings an economic gain in the replacement of parts and in the production of functional rapid prototypes.
