Felt forming is the process of converting acoustic felt into automotive interior parts via 2D/3D hot or cold press forming. Headliners, door inner panels, parcel shelves, boot trims and engine-bay insulation parts — OEM and aftermarket series production. Combines lightness, acoustics and aesthetics in one part.
What is felt forming?
Felt forming is the process of pressing acoustic felt — typically PET, polyester or composite — into a mould under heat and pressure to give it the required 2D or 3D shape. The formed part provides acoustic absorption (NRC 0.40-0.75), impact-vibration damping and a finished interior surface. Primary use is automotive; also used in appliances and rail/aviation interiors.
Production technologies
- Hot-press forming: thermoset-resin felt with heated mould
- Cold-press forming: thermoplastic-bonded felt
- Vacuum forming: thin complex geometry
- Mould + blade combination: form + edge trim in one step
- Surface lamination: fabric, leather, vinyl finish
Material types
- PET / polyester felt: recycled, lightweight
- Bi-component (BiCo) fibre: thermoplastic binder
- Glass-wool composite: high temperature (engine bay)
- Natural fibre (hemp, jute): sustainable alternatives
- Barrier + felt sandwich: insulation + finish
Where it is used
- Automotive headliners
- Door inner panel insulation
- Parcel shelves and boot inner trim
- Under-bonnet engine-bay insulation
- Felt layer under floor carpet
- Appliance internal decorative insulation
- Train and rail-system interior trim
Performance
- NRC: 0.40-0.75 (thickness and density dependent)
- Surface weight: 800-2400 g/m²
- Thickness: 4-30 mm (after forming)
- Temperature resistance: 90 °C standard, 150 °C engine bay
- Fire class: FMVSS 302, UL 94 V-0 certified
OEM workflow
1) Drawing / 3D model + sample approval. 2) Mould manufacturing (CNC steel mould). 3) Pilot run and OEM quality testing. 4) Series production go-live. 5) JIT or stock-based supply model. 6) Lot reports and certificate traceability.
