Today we would like to tell you a bit about how we make our thermoforming moulds at D.F.: the moulds are made of steel, they are in two parts and are used to hot mould acetate temples or temple tips which have already been cut with a punch. Punching gives us a semi-finished product which is then moulded to define the camber and the edges of the acetate part. At the same time, these moulds enable us to insert the core in the temple or make a hole on the temple tip using a core pusher or punches which we manufacture ourselves.
How do we manage your project? To produce your part, you can send us a two-dimensional drawing with all the sections and measurements on it or a 3D drawing of the finished part: in the first case, the project is examined by our Technical Department which creates the 3D drawing, whereas in the second, the drawing is checked and altered if necessary before it is processed and loaded into the machine. According to your needs, we can produce either traditional closed moulds or moulds that can be opened.
Depending on the geometries of your part, we can make the mould using a CNC milling machine or by electro-erosion if there are very small details on the temple or tip which we cannot obtain with the milling machine. At the end of these stages, we manually polish and control the male/female coupling.
Thanks to the professional expertise of our team and our state-of-the-art machinery, we are able to handle any project.
