AUTOMOTIVE SEATING TECHNOLOGY
Advanced Mold-In Fastening Systems for Automotive Seating
Secure, consistent attachment between polyurethane seat foam and automotive trim covers.

MOLD-IN HOOK
PU FOAM
BUILT FOR SEAT ASSEMBLY
From the foam mold to the finished trim.
ELCRO develops automotive hook-and-loop components around the complete seat-assembly process. The backing integrates with expanding PU foam while the hook face creates a repeatable connection to loop material sewn into the seat cover.
Reliable performance
Automotive material construction engineered for secure foam integration.
Consistent attachment
Controlled dimensions and repeatable engagement for trim-cover assembly.
Custom geometry
Straight, curved and die-cut formats developed from customer drawings.
How it works
- 01Position in mold
- 02Inject PU foam
- 03Cure & integrate
- 04Attach trim loop
PRODUCT PLATFORM
Fastening components engineered around the seat.
Standard constructions and custom converting options support cushion, seat-back and trim applications.
01SEAT FOAM
Non-Cover Mold-In Hook
Flexible mushroom-hook strip with PET film, iron powder and mesh backing for direct integration into PU seat foam.
- 4.5 ± 0.1 mm
- ±0.1 mm L/W tolerance
- Custom die-cut shapes
02PROTECTED HOOK
Cover Mold-In Hook
Protected engagement surface and reinforced backing designed for controlled foaming and clean trim assembly.
- 4.5 ± 0.1 mm
- Paper protective layer
- Fe-powder backing
03SEAT COVER
Automotive Loop
Flame-retardant polyester loop sewn into the trim cover to mate with the mold-in hook.
- 3.2 ± 0.1 mm
- 36 / 38 / 40 mm

ENGINEERING EVIDENCE
Designed to become part of the foam.
ELCRO’s rear structure gives expanding foam more area to penetrate and anchor. Internal comparison images indicate deeper integration and reduced incomplete formation around the fastening channel.
