Either chemical or physical foaming agents are used in the production of structured foam parts. Chemical foaming agents are added to the plastics granulate in the form of master batches, powders or liquids. Gases or liquids are used as physical foaming agents, which are injected into the barrel. The foaming agent used in the Cellmould process is nitrogen. This technology is ideally suited for manufacturing light, structured components.
Cellmould ligthweight technology enables the production of foamed, highly rigid parts without sink marks. The aim of the Cellmould lightweight technology is to produce both thick-walled and thin-walled structural foam parts with a fine and even foam structure with reduced weight.
Advantages of the Cellmould application
- Weight reduction
- Plastic material savings
- Reduced component costs
- Prevention of sink marks
- Reduction of warpage
- Narrower tolerances
- Higher rigidity with the same weight
- Longer maximum flow paths due to reduced viscosity
- New scope for design
- Reduction of cycle time
- Lower clamping forces
