Construction & infrastructure
Between concrete elements, on bridges and in tunnels, heavy rubber profiles do the sealing. Their large cross-sections must be cured right through to the core.
Typical materials
- EPDM
- CR
The product
Profiles for civil engineering are large, heavy and must stay elastic for decades. The production challenge: getting heat evenly into the core without overheating the surface.
Typical products
- Joint and expansion joint profiles in concrete construction
- Profiles for bridge expansion joints
- Seals for precast concrete elements and shafts
- Tunnel segment gaskets as closed frames
What matters
- 01
Cured to the core
Large cross-sections need energy from the inside and sufficient dwell time.
- 02
Permanently elastic
Resistant to ageing and weather for the life of the structure.
- 03
Strong joints
Frames and rings whose joint is as robust as the profile.
The line
These TSM systems are typically used – in production order:
- 01
ExtrudersExtruders up to 120 mm screw diameter and 650 kg/h for large cross-sections. - 02
Microwave SystemsUHF brings heat directly into the core of the profile. - 03
Hot Air SystemsLong hot air sections for the required dwell time. - 04
Cooling LinesControlled cooling of heavy profiles. - 05
Splicing PressesJoins profiles into frames and rings. - 06
