High-Tech Precast Concrete Hollow Core Extruder: Modernizing Your Production

For manufacturers of reinforced concrete structures, it is critically important to implement solutions capable of reducing costs and improving the quality of finished slabs. Outdated lines require enormous maintenance costs, regularly stand idle, and do not always provide the required geometry or pouring density. The ideal way out of this situation is modern Finnish equipment from TDM Engineering Oy, designed specifically for the needs of advanced enterprises. Professional concrete slab manufacturing equipment allows precast plants to reach a fundamentally new level of profitability by accelerating workflows and completely eliminating production defects.

The Essence of the Technology: Uncompromising Reliability and Perfect Mixture Compaction

The production principle of TDM brand machines is based on the extrusion method—forcing a rigid mass through void formers under extremely high pressure. A powerful precast concrete hollow core extruder is equipped with a reliable power unit, a reciprocating compaction module, and a high-capacity concrete hopper, the volume of which can be increased from the standard 1.5 to 3.0 cubic meters. The installation moves along the rails of the casting bed, which act as chamfer formers, while the track of the machine is only 90 millimeters wider than the slab itself.

The compacting group of the UniMould platform is based on a solid wheel frame and uses from two to eight electric motors. Independent drives rotate the augers, and electronic gearbox control allows you to monitor the process with absolute precision. As a result, the mixture is perfectly compacted and laid on the casting bed at a speed of 1.4 to 2.5 meters per minute, forming a flawless structure of the reinforced concrete product.

Practical Application in Modern Precast Plants to Expand the Assortment

The versatile panel production machine from the Finnish brand easily adapts to the individual needs of the enterprise and is used to implement the following technological scenarios:

• Mass production of classic floor slabs with a height of 120 to 600 millimeters on casting beds 1200, 1500, or 2400 millimeters wide.
• Molding of thin wall panels and partitions with a minimum height of 80 millimeters using the specialized flexible L-series.
• Pouring reinforced concrete over an insulation layer with convenient height adjustment to ensure the required fire resistance classes of the finished products.
• Continuous casting of ultra-stiff mixtures thanks to the automatic adaptation of compaction intensity to the specific properties of the used concrete.
• Organization of a safe maintenance process directly above the slab due to the built-in service platform with footboards and ladders on three sides.

Key Advantages and Economic Benefits for Your Business

Independent auger drives guarantee exceptional compaction even when working with the most rigid building mixtures. Thanks to the complete absence of complex gearboxes and cardan shafts, the enterprise permanently gets rid of the risk of expensive sudden repairs.

The newly designed high-frequency vibrating screed ensures uniform vibration transfer with a minimum level of operational noise in the workshop. The use of special wear-resistant materials in the design of the high-capacity concrete hopper and forming wear plates significantly extends machines for the production of floor slabs the uninterrupted service life of the unit.

The innovative S-series precast concrete hollow core extruder is additionally equipped with an intelligent touch interface featuring machine learning functions. The launch of all critical production processes is carried out by pressing a single button, which radically reduces the daily workload on the operator.

Equipment Lineup: From Basic Tasks to Full Process Automation

When choosing a suitable precast concrete hollow core extruder, the customer can select the optimal modification for the planned production volumes. The flagship S-series is the most advanced modular unit with an 11-inch color monitor and a maximum casting speed of up to 3.0 meters per minute. The N-series is a powerful workhorse with an 8-inch screen and separate drives for intensive daily production. If a plant requires a compact solution for the flexible and economical production of wall partitions up to 220 millimeters high, engineers offer the L-series.

In all presented models, an improved system for adjusting the side forming plates in three planes is implemented. External access to the bolts allows maintenance personnel to quickly reconfigure the line without prolonged downtime. Furthermore, the hermetically sealed upper part of the front module reliably protects the pre-stressed concrete machinery mechanisms from dust and dirt.
