Production of film hinges: the basics

The production of film hinges involves many steps. The injection molding process is very important. It makes it possible to produce precise and versatile film hinges.

Process sequence in injection molding

Injection molding begins with the choice of material and mold. Here are the most important steps:

  1. Material selection: The right plastic material is selected.
  2. Heating: The material is heated to make it malleable.
  3. Injection: The liquid material is injected into a mold.
  4. Cooling: The mold is cooled so that the material becomes solid.
  5. Removal: The finished film hinge is removed from the mold.

Important technologies

Special technologies are required for the production of film hinges. They improve efficiency and functionality:

  • Injection molding: A popular technique for complex designs.
  • Multi-component injection molding: Allows different materials to be combined.
  • Overmolding technology: Adds additional components or materials.

Design and customization of film hinges
