Future Construction Technologies: Equipment for Producing Precast Concrete Slabs — How Finnish Innovation Is Changing the Precast Market
In modern construction, speed and profitability decide everything. To stay competitive, companies must adopt technologies that cut costs without sacrificing quality. That is why professional equipment for producing precast concrete slabs has become a key asset for any precast plant. TDM Engineering Oy delivers solutions that turn precast production into a high‑precision, fully automated process.
The core of formwork‑free casting technology
Long‑line extrusion of slabs is fundamentally different from outdated battery‑mould methods. There is no need for bulky moulds or long waiting times for demoulding. The heart of the line is the extruder — a powerful screw‑type machine with a flexible, dynamic drive.
The process works as follows: the machine moves on rails along the casting bed, continuously placing the concrete mix. Inside the extruder, the augers rotate and perform reciprocating movements. This delivers ultra‑high concrete compaction — far higher than conventional vibration.
High‑quality equipment for producing precast concrete slabs from TDM Engineering typically covers the full production cycle, including:
- An extruder for shaping the product.
- An addressable concrete delivery system (rail tracks and a self‑propelled bucket).
- Casting bed cleaning machines.
- Equipment for prestressing steel strands.
- High‑precision saws for cutting hardened concrete at any angle.
Such production lines enable nonstop output while minimizing workshop downtime.
Where next‑generation products are used
Hollow‑core floor slabs produced by extrusion are in demand across the board. Thanks to prestressed reinforcement, they withstand enormous loads with lower self‑weight. This makes them an ideal solution for:
- Multi‑storey residential construction.
- Industrial buildings with large spans.
- Shopping centres and parking structures.
- Infrastructure projects.
Universal equipment for producing precast concrete slabs allows flexible changes in the product range. For example, one line can manufacture slabs of different heights (from 160 mm to 500 mm) and widths by simply re‑configuring the extruder — opening the door to even the most complex architectural projects.
Why market leaders choose extrusion
Switching to modern formwork‑free casting machines brings clear economic benefits.
First, it reduces unit cost. The technology allows the use of low water‑to‑cement ratios, saving cement and shortening drying time.
Second, it improves geometry and quality. Slabs come out with a perfectly smooth surface that requires no additional finishing, and with precise dimensions. Automatic saws of the L, S, or SU series handle any cutting task — longitudinal, cross, and angled.
Third, it increases automation. Reliable slab‑production equipment requires minimal operating staff, reducing the human factor and labour costs.
