3D-Printed Mold Insert for CVM Technology
X2F sells patented injection molding machines that enable users from a wide variety of
industries to efficiently produce highly integrated, protected, and functional components.

The CVM process allows for the processing of a wide range of
materials through a precisely controlled, volumetric material feed. This creates new
degrees of freedom in product design, as well as robust and scalable manufacturing processes.

Advantages:
- Low shear stress
- Constant material viscosity
- Uniform cavity filling
- Minimized internal stress
- Processing of sensitive materials
- Flexibility for thin-walled parts or long flow paths

Applications:
- Printed circuit board protection
- Motors
- Housings and covers
- Connectors
- Optical components
- Batteries

Process Flow:
- Material viscosity is continuously monitored and controlled
- Sensors for temperature, pressure, and torque continuously collect data
- Based on this data, the screw rotation is dynamically adjusted -> viscosity remains consistently within the operating window
- The cavity is filled evenly and in a controlled manner
- This is followed by a pulse packing phase, which
is continuously monitored -> Material distribution and solidification can be reproducibly adjusted
