Many silicone molds look similar at first glance. However, the differences quickly become apparent in everyday use - especially when filling, carrying, and portioning. This is precisely where a metal frame makes a bigger difference than many might initially think.

In short

A metal frame is not a design detail, but a true functional element: It transforms a flexible mold into a much more practical solution for everyday use.

The typical disadvantage of many standard molds

Standard silicone molds are often soft and flexible, but also unstable. As soon as there is content in the mold, carrying becomes less secure. Liquid foods, small casseroles, or prepared portions can then quickly feel wobbly.

What Swiss sources contribute

The FOPH defines the frame for dishes and kitchen utensils as food contact materials. The practicality then results from the specific construction - how well a product is made for its purpose.

Why FRiBA has a clear advantage here

FRiBA's silicone molds do not just use the metal frame as an addition, but as a central functional element. Together with the lid, ml scale, and suitability for freezer and oven, a mold is created that can do significantly more than standard silicone: more stable, more precise, and more practical.

In brief
  • The metal frame stabilizes the most stressed upper rim.
  • This leads to: safer carrying, less bending, cleaner filling.
  • Everyday usability results from the construction (FOPH).
  • With a lid, ml scale, and oven/freezer suitability, FRiBA can do more.
