Custom foam inserts are widely used for tool cases, electronics packaging, medical equipment protection, and industrial products.
The biggest production challenges are usually not whether foam can be cut, but whether it can be cut consistently with low waste.
Common customer problems
- Too much foam wasted during layout
- Narrow walls between pockets breaking
- Manual cutting taking too much labor
- Prototype changes requiring repeated work
How CNC oscillating knife cutting helps
A CNC knife cutting machine allows manufacturers to create digital cutting files, optimize layouts, and repeat designs without making physical dies.
Key considerations:
- Foam type
- Thickness
- Density
- Pocket spacing
- Blade selection
- Vacuum holding
FAQ
Can CNC machines cut EVA foam inserts?
Yes. EVA, PE, EPE and many flexible foams can be processed after proper testing.
Is die cutting better than CNC cutting?
Die cutting is suitable for large fixed-volume production. CNC cutting is more flexible for custom and changing designs.
