FOAM MICROCELLULAR MOULDING®

Foam Microcellular Moulding (FMC) Process

More and more plastic components need mechanic resistance and weight reduction.  Using Negri Bossi’s experience in gas injection, we have developed a solution which reduces the component weight, increases the mechanical properties and enhances the chemical quality of the material.

This application produces moulded material in a microcellular form and is available for both thermoplastics and liquid silicon rubber (LSR).

FMC Idea

Simplicity

Simplicity is the key word. The primary goal was to find a solution where there were no major changes to the base components of the machine whilst simultaneously obtaining a microcellular result via a reliable and repeatable process, configurable to the product’s needs.

Another challenge was to apply this process to all Negri Bossi’s existing machines, not only the current series but to those already installed at our customers.

Advantages

  • Weight Reduction: less material used
  • Viscosity melt reduction during injection phase
  • Clamping force reduction for the piece production
  • Cycle time reduction
  • Improved dimensional moulding control

How FMC Works

How FMC Works

Foam Microcellular Moulding processNegri Bossi FMC® system doesn’t have dosing limits, the gas is injected directly into the screw which allows you to use the entire dosing stroke, so the user can use a standard chamber rather than be bound by the dose. This means a melt can be obtained with an external solid layer and an internal microcellular structure: this is achievable thanks to gas insertion in the screw during the moulding cycle. This technology is available for a wide range of materials.
