Low-cost formulas in the manufacturing of non-stick food molds

To date, this manufacturing was only done at specialized factories, equipped with huge presses and dies, that made these molds by means of deep drawing. Once shaped, the molds had to get their non-stick coating at a different site. This process is only cost-effective when thousands of identical molds are made, which makes it an insurmountable obstacle for small businesses.

Based on this casuistry, the University of Cordoba Manufacturing Department research group developed a new technique to manufacture these pieces at a machining center, thus completely changing the normal process. This alternative method makes molds from metal sheets covered with non-stick coating. Though this process is slower, it is more affordable and easy to use.

Formula - Sheet - Teflon - Plastic - Material

The new formula consists of simultaneously transforming a metal sheet covered in teflon (very resistant plastic material) and a PVC sheet. A punch with a rounded tip gradually shapes both sheets until the right shape is reached. The path of the punch is directed by a computer that determines the precise movements it makes.

This solution allows for shaping the metal sheet without damaging the non-stick coating at any point, since the non-stick coating is protected by the PVC sheet. In this way,...
