The purchase of an extruder for the production of hollow core slabs is a serious investment that requires careful analysis. The efficiency and quality of future production directly depend on the correct choice of equipment. Let's take a look at the key aspects to consider when buying an extruder.

The principle of extruder operation

Extruders form hollow core slabs using a formless molding method. Concrete mixture is fed into the machine's hopper, where augers under high pressure compact it and form a product of the desired shape and size. The process takes place directly on the production track, eliminating the need for formwork and speeding up production.

Important characteristics when selecting

1. Range of sizes of slabs to be produced: Make sure the extruder is capable of producing slabs of the required height and width. Modern models can produce products from 120mm to 600mm high and 600mm to 2400mm wide.

2. Productivity: The molding speed affects the volume of output. Some extruders are capable of forming plates at speeds of up to 3 meters per minute, which improves overall production efficiency.

3. Reliable and easy to maintain: Choose equipment with a robust design and accessible maintenance components. This will reduce downtime and repair costs. Compatibility with other elements of the production

4. line: The extruder should integrate with existing concrete distribution, rebar tensioning and slab cutting systems. An integrated approach will ensure the smooth running of the entire production process.

Additional functions and technologies

Modern extruders are equipped with advanced technologies:

  • Independent screw drives: ensure that the concrete compaction process is fine-tuned, adapting to the properties of the concrete.
  • High-frequency vibrating rails: promote uniform compaction of the mix, improving the surface quality of the slabs.
  • Intuitive control interface: simplifies the operator's work and allows him to react quickly to changes in the production process.

The TDM-1200, TDM-1500 and TDM-2400 extruder models stand out on the market. The first one is suitable for the production of plates up to 1200 mm wide and has high productivity with compact dimensions. The second model - TDM-1500 - is oriented for large-scale production with maximum slab width up to 1500 mm and advanced vibration compaction system, the third for slab width up to 2400 mm.

The models are characterized by a modular design, which facilitates maintenance and adaptation to different applications. They are equipped with an intelligent control system that allows precise regulation of the molding process. Thanks to their high quality and stable operation, TDM extruders have proven themselves on modern production lines.

Choosing a hollow core extruder is an important task, and the success of your production depends on it. Take into account technical features, compatibility with other systems and the availability of state-of-the-art technology. Careful analysis and expert advice will help you make the right choice, ensuring high product quality and efficient operation.
