The Precast concrete curb extruder machine work on the principle of extrusion to produce the concrete curbs. The curb extruder is equipped with extrusion shaft screws in its body. By the rotation of the screws (augers), the concrete curbs is extruded and then are molded to the specified shape and sizes such as the concrete curbs. Compared to the curb slip form machine, the machine produces the curbs in the means of precast methods. It can manufacture the specified size and shape of curbs in the precast factory and in the cast site. And then, according to the actual needs, the curbs can be cut into the required length.
The following are the advantages and characteristics of using the concrete kerb extrusion machine to produce concrete curbs
1. Fast forming speed 2-3 meter/ minute
2. Perfect surface finishes. The curbs surface is without any wrinkles and folds.
3. Easy operation and Low maintenance cost
4. The machine allow to add the prestressed steel wires in the concrete kerbs
5. The machine is compact and easy to move
