Modern construction requires high-tech solutions for the production of reinforced concrete structures. Finnish manufacturers, such as TDM Engineering, offer innovative technologies for the production of prestressed hollow core floor slabs, ensuring their strength, durability and cost-effectiveness.

Extrusion technology for the production of hollow core slabs

Finnish companies use the extrusion method, which makes it possible to produce prestressed hollow core floor slabs without the use of traditional formwork systems. An extruder compacts the concrete mixture and deposits it on a molding track, creating strong and lightweight structures

The main advantages of the extrusion method are:

  • High productivity - molding speeds up to 3.5 m/minute
  • Uniform distribution of the material, which increases the mechanical properties of the slabs
  • Possibility to create slabs with different parameters - height from 60 to 600 mm and width up to 2.4 meters.

Key equipment for the production of prestressed hollow core floor slabs

Finnish technology offers complete production equipment, including not only extruders but also auxiliary machinery.

1. Extruder for hollow core slabs - TDM Engineering extruders are equipped with independent screw drives, which allows for precise control of the compaction process. Modern models also include vibrating rails, improving the quality of the slabs

2. Slab cutting saws - Cutting equipment allows for precise longitudinal and transverse cuts. Some models feature automatic speed control, as well as built-in memory to store cutting parameters

3. Automatic concrete delivery systems - Modern targeted concrete delivery systems automate the process of transporting the mix, reducing losses and increasing efficiency.

4. Forming tracks - Metal walkways with a heating system ensure reliable forming of slabs and accelerate the curing process of concrete

Innovations in the production of hollow core slabs

Finnish manufacturers are actively introducing the latest technologies to improve quality and reduce the cost of production.

  • Automation - Modern production lines include computerized control systems that monitor extrusion parameters and minimize the risk of errors.
  • Use of composite materials - In addition to traditional concrete, composite materials such as fiberglass reinforced polymers are increasingly being used. These make the slabs lighter but still maintain their strength
  • Adjustable voids - Modern extruders make it possible to change the shape and size of the voids, adapting the boards to specific building applications.

Advantages of Finnish technology in the production of hollow core slabs

  • Resource saving - reduced concrete costs due to efficient compaction of the mixture.
  • Production speed - automated lines allow to produce slabs faster.
  • Flexible production - slabs of different heights, widths and void structures can be produced.
  • Load resistance - innovative reinforcement methods increase the durability of the products

Finnish technology in the production of hollow core slabs allows construction companies to create strong, reliable and economical structures that meet modern requirements for quality and durability.
