Concrete Extruder Machine
A concrete extruder, or extrusion press, is a machine that uses extrusion technology to create hollow core slabs.
The powerful screw system and the right combination of rotation, thrust and vibration of our extruder mechanism allows for greater compaction of concrete than in a casting machine.
Advantages
Manufacture of hollow core slabs with larger holes and lighter weights
Savings in the manufacture of concrete as well as in the logistical costs of transportation and on-site casting.
The high density of the concrete reduces the amount of cement and water used, thereby increasing the strength of the concrete while reducing setting time.
Extrusion technology
Extrusion technology is a way to achieve higher quality in the manufacture of hollow core slabs. This technology is used in concrete extruders to obtain lighter slabs and better water/cement ratios.
In addition, hollow core slabs manufactured with extruders are more durable.
Another quality of precast products manufactured using extrusion technology and concrete extruders is their faster setting. By using less water, the setting time is shorter.
