Transitioning to modern manufacturing methods for reinforced concrete products is a mandatory step for any plant striving to increase profitability. Process automation not only minimizes the human factor but also ensures consistently high quality of the finished product. The Finnish company TDM Engineering Oy offers solutions that optimize production cycles through the use of high-performance extruders. This equipment provides perfect geometry and high concrete density, which is critical for meeting modern construction standards.

Operating Principle and Key Technology Features

The equipment operates on the extrusion principle, where the concrete mix is forced through a forming group under high pressure. The main working elements are the screws, which compact the material and form longitudinal voids. The casting process occurs continuously on long production beds. A modern Hollow-core slab casting machine automatically adjusts the intensity of the reciprocating compaction based on the concrete characteristics, guaranteeing structural uniformity throughout the entire length of the product.

The equipment is built on a modular principle, allowing for flexible configuration to meet specific production tasks. Independent screw drives simplify operation and provide exceptional compaction even when working with stiff mixes. A control system featuring a touchscreen and machine learning capabilities monitors all critical parameters in real-time. This minimizes the risk of errors and increases the stability of finished product output on lines dedicated to hollow-core slab production.

Industrial Application and Model Range Capabilities

The primary area of equipment operation is the industrial manufacturing of hollow-core slabs of various heights and configurations. The Hollow-core slab casting machine is actively used in precast plants to create structural elements for residential, commercial, and industrial buildings. Depending on the chosen series (S, N, or L), an enterprise can produce items with a cross-section height ranging from 80 mm to 600 mm. This versatility covers the needs for both standard floor slabs and specialized structures with high load-bearing requirements.

Standard lines are designed for 1200 mm wide beds; however, the design allows for the manufacturing of units for 600, 900, 1000, 1500 mm and 2400 mm tracks. A reliable Hollow-core slab casting machine is capable of operating at speeds up to 2.5 meters per minute, ensuring fast turnover of the casting beds. This directly impacts the economic efficiency of the enterprise, allowing for a higher output of square meters per shift. The adjustment of side-forming shields in three planes provides easy access to settings and ensures the precision of every slab's parameters.

Technical Advantages and Business Benefits

Professional equipment for hollow-core slab production from TDM Engineering Oy is designed for harsh operating conditions and component longevity. Key advantages of the system include:

  • High Reliability and Maintainability: The design lacks complex gearboxes and cardan shafts. This eliminates the need for frequent maintenance and significantly reduces the risk of costly downtime and sudden breakdowns.
  • Wear-Resistant Working Parts: All components in contact with abrasive concrete, including the concrete hopper, void formers, and vibrating beams, are made of high-strength materials with an extended service life.
  • Resource Optimization: Precise mix dosing and the ability to adjust the casting height allow for a reduction in cement and aggregate consumption while maintaining the rated strength characteristics of the products.
  • Low Noise Impact: The newly designed high-frequency vibrating beam provides effective compaction with a minimal acoustic background, improving working conditions for floor staff.
  • Intelligent Interface: The intuitive control system allows for the activation of all extruder systems with a single button, while all casting process data is easily readable on a color monitor.
