Working Principle For Precast Concrete Slab Making Machine
- Raw materials (cement, sand, aggregates) are mixed
- Concrete is fed into the extrusion hopper
- Screw augers push the material through the mold
- Vibration compacts and shapes the hollow core or solid slab
- Continuous extrusion forms slabs with uniform thickness and hollow cores
- Slabs are cut, cured, and ready for installation
This integrated process ensures continuous, high-speed, and precise production.
Our Concrete Hollow Core Slab Machine (also known as the Hollow Core Extruder) is engineered for high-speed production of prestressed concrete slabs. These slabs are widely used for flooring, roofing, and fencing due to their lightweight nature and high load-bearing capacity.
🧱 Raw Materials
- Cement
- Sand / Fly Ash
- Aggregates (natural or lightweight)
- Water
