1. Hollow Core Slab Production Line
Key Steps:
Raw Material Preparation: Cement, aggregates, water, and admixtures are batched and mixed to a specific design.
Concrete Feeding: The wet concrete mix is fed into a long steel bed.
Extrusion / Slip Forming: Concrete is extruded continuously, forming hollow channels inside the slab by a hollow-core former.
Vibration & Compaction: External and internal vibrators compact the concrete to remove air voids.
Initial Curing: Slabs are left on the bed to gain initial strength; often steam curing is applied.
Cutting: The long slab is cut into required lengths using diamond wire saws.
Demolding & Stacking: Slabs are demolded or lifted off the bed and stacked for further curing.
Final Curing: Slabs cure fully in a controlled environment before delivery.
2. Concrete Block Production Line
Key Steps:
Mixing: Dry concrete mix with low water content is prepared.
Concrete Feeding: The mix is transported to the block machine hopper.
Molding & Vibration Pressing: The mix is placed into steel molds on pallets and compacted by high-frequency vibration and pressure.
Demolding: Blocks are ejected from molds onto curing pallets.
Curing: Blocks undergo steam or ambient curing for several hours to days.
Stacking & Packaging: Blocks are stacked and prepared for shipment.
3. Precast Wall Panel Production Line (Tilting Table)
Key Steps:
Mold Preparation: Large tilting tables with mold surfaces are cleaned and treated with release agents.
Concrete Pouring: Wet concrete mix is poured into the mold.
Vibration: Tables vibrate to compact the concrete.
Casting Inserts: Embedded items like rebar, conduits, or insulation are positioned.
Initial Curing: Panels remain on the table for initial set.
Tilting & Demolding: Table tilts hydraulically, and the panel is demolded.
Final Curing: Panels cure fully in storage racks.
Finishing: Surface treatments, coatings, or openings are prepared.
4. Concrete Pipe Production Line (RCC Pipe Machine)
Key Steps:
Mix Preparation: High-strength mix designed for pipe durability.
Mold Setup: Steel pipe molds are fixed vertically or horizontally.
Concrete Pouring: Concrete is fed into the mold.
Vibration / Centrifugal Casting: Mold vibrates or spins to consolidate concrete and achieve uniform density.
Initial Curing: Pipes remain in molds for initial set.
Demolding: Pipes are removed carefully to avoid damage.
Final Curing: Pipes cure fully on racks.
Quality Testing: Pipes undergo strength, dimension, and leak tests.
5. Prestressed Beam Production Line
Key Steps:
Prestressing Steel Installation: High-strength steel tendons or cables are tensioned on casting beds.
Formwork & Mold Setup: Molds are positioned on the bed with necessary supports.
Concrete Pouring: Concrete mix is poured into molds.
Vibration & Compaction: Concrete is vibrated for consolidation.
Curing: Accelerated curing methods (steam) help achieve early strength.
De-tensioning: Tendons are gradually released to impart compressive prestress to the beam.
Demolding & Storage: Beams are removed and stored for final curing.
Finishing & Quality Inspection: Beams are checked for strength and dimensional accuracy.
6. Manhole and Concrete Ring Production Line
Key Steps:
Mold Preparation: Vertical molds for rings and covers are cleaned and greased.
Concrete Feeding: Concrete mix is fed into the mold.
Vibration: Vertical core vibrators compact the concrete.
Initial Setting: Rings remain in molds until concrete sets sufficiently.
Demolding: Rings and covers are demolded.
Curing: Products cure in racks under ambient or controlled conditions.
Inspection: Dimensional checks and strength tests are performed.
