Hamer designs and manufactures moulds and tooling sets for production equipment of containers and packaging. We apply our knowledge to conceive and design the tooling, although we can also import designs to our system of CAD files supplied by the client.

We have several CNC machining centers, we work materials such as aluminum, steel or technical polymers for the manufacture of moulds. We take care of critical aspects such as refrigeration and vacuum circuits that will allow the proper control of the moulding process.
The final assembly and finishing of the moulds is done in our facilities, working the finishes by hand in order to guarantee a superior finish in the pieces.
