Casting of Hollow-core with extruder is changing the hollow core slab market
In modern construction, hollow core slabs play a key role in ensuring the reliability and durability of buildings and structures. However, traditional methods of production require the use of formwork, which increases the cost of materials, labor, and production time.
With the development of technology, an innovative method has emerged – formwork-free slab molding, which significantly changes the approach to the production of hollow core slabs. This method is characterized by high efficiency, significant resource savings and improved product quality. Thanks to the introduction of modern equipment, such as extruders for the production of hollow core slabs, hollow core molding is becoming increasingly popular among construction companies and manufacturers of reinforced concrete structures.
Advantages of casting of Hollow-core with extruder
Casting of Hollow-core with extruder is an advanced method of producing prestressed reinforced concrete slabs that does not require the use of metal or wood forms. This approach offers many advantages:
- Reduced consumable costs since there is no need for formwork.
- Reduced production cycles due to the automated process.
- High geometric accuracy of the slabs, which reduces the need for additional processing.
- Improved working conditions, as the amount of manual labor is reduced.
- Space saving in production, as there is no need to store and maintain formwork structures.
- Increased strength of products due to uniform compaction of concrete.
- Reduced production waste, which makes the process more environmentally friendly.
In addition, due to the absence of formwork, the costs of its manufacture, installation and dismantling are significantly reduced, which is especially important in the mass production of floor slabs.
Casting process of Hollow-core with extruder is changing the market for hollow core slabs.
The hollow core casting process consists of several sequential steps:
- Steel strands preparation: tensioning of reinforcement strands or wires.
- Forming: using modern equipment such as extruders, the concrete mixture is placed, compacted and formed without the use of formwork.
- Compaction process: a special vibrating or extrusion mechanism ensures uniform distribution of the mix.
- Cutting and finishing: once the slabs have gained strength, they are cut to the specified dimensions and given a final finish.
Modern extruders, such as the equipment from TDM company, allow to produce slabs from 120 to 600 mm in height with high speed and minimal costs. Thanks to the automation of the process, stable product quality is achieved.
Application and prospects
Slabs made by the method of casting of hollow-core with extruder is changing the market of hollow core slabs, widely used in construction:
- Residential apartment buildings and private cottages.
- Public buildings (schools, hospitals, shopping centers).
- Industrial facilities (factories, warehouses, logistics centers).
- Infrastructure facilities (bridges, tunnels, parking lots).
Due to their high load-bearing capacity and precise geometry, such slabs allow to significantly reduce construction time and installation costs. In addition, their use makes buildings more energy efficient due to improved heat and noise insulation. With the development of technology and the emergence of more productive machines such as TDM extruders, formless molding is becoming more and more popular in the market. It opens up new opportunities for producers of reinforced concrete products, increasing competitiveness and setting new quality standards in the construction industry.
Casting of Hollow-core with extruder is changing the hollow core slab market – it is a breakthrough in the production of hollow core floor slabs. It reduces costs, increases productivity and ensures consistent quality of reinforced concrete products. The introduction of advanced extruders enables construction companies and reinforced concrete plants to respond faster to market demands, minimize costs, and improve product performance. As a result, this technology is changing the market, making it more efficient, environmentally friendly and technologically advanced.
