Precast Concrete Wall Panel Extruder Machine

About the JQT series precast wall panel extruder

The precast concrete wall panel extruder machine is specially designed to manufacture the non-bear loading concrete hollwo core or soild lightweight wall panels . The wall panels are mainly used as the partition wall in any frame construction buildings such as common steel-concrete structures and steel structures.

This concrete wall panel extrusion machine integrates the multi-processes of feeding materials, vibration, forming, extrusion, and demolding produced by lightweight concrete wall panels. The main motor transmits the power to the reduction box through the pulley, and the output shaft of the reduction box drives the screwing augers to rotate in the forming cavity consisting of machine frame, vibrator and pedestal constitute. The concrete materials from the hopper are continuously conveyed to the forming cavity, and the materials are extruded by the screw augers in the forming cavity and are vibrated by the vibrator. With the continuous dual force action, it produces resonance. The concrete component reaches the required shape, size, and degree of compaction. At the same time, the vibrated and compacted wall panels produce a reaction force against the rotating screw augers, forcing the wall panel extruder to continuously move forward to realize a continuous wall panels production. The surface top of the wall panel is polished through the forming scraper at the end of the machine. The final wall panels will be very smooth and compact.

Raw Materials and formula for manufacturing wall panels 

• Cement+ sand/fly ash + lightweight concrete aggregate.The common lightweight aggregate is the slag, Leca， Volcanic ash(stone), pumice stone, expanded perlite, etc
• Cement+ sand/fly ash+Recycled Concrete Aggregates and other waste materials. 
• Cement+sand+nomral aggregate (broken stone)

The governance features of the mix for the lightweight wall panel machine are that it must be earth dry, zero slump concrete with a set particle-size distribution for aggregate. The weight of wall panels made with lightweight aggregate is half of that of ordinary aggregate wall panels.

Precast partition panels produced via precast concrete wall panel extruder machine represent the fastest method currently available for constructing non-load-bearing partition walls, offering exceptional fire resistance and noise reduction performance. Their ease of installation delivers additional benefits. The key advantages and benefits include: 

1. Enhanced Productivity
Traditional on-site construction methods (e.g., bricklaying or blockwork) often prove inefficient. As demand for rapid construction projects grows, reliance on these conventional approaches may significantly escalate labor costs or result in lost opportunities. These panels enable wall installation six times faster than traditional brick walls and twice as fast as block walls, with two workers capable of installing up to 10 square meters per hour.

2. No Specialized Labor Required
Installation of prefabricated partitions is straightforward with proper guidance. There is no need to employ highly skilled workers (e.g., bricklayers or masons) for installation. Since general construction workers can perform the work, labor costs for projects utilizing these panels are substantially lower.

3. Plastering-Free Installation
The prefabricated wall panels are manufactured from cement and lightweight aggregates. The incorporated solid stone composition enhances property value. Factory-finished with superior surface quality, the panels only require a surface coating, eliminating extensive plastering and finishing expenses.

4. Hollow-Core Structure Provides Natural Conduits
The hollow-core construction technology creates natural channels within the panels for plumbing, electrical wiring, HVAC systems, and water installations. No chasing or grooving is required. Modifications can be easily executed through cutting or drilling, further reducing labor and associated costs.

5. Fire Resistance
The materials used in panel production endow the finished product with inherent fire-resistant properties. Suitable for diverse applications ranging from residential to commercial buildings, fire performance improves with panel thickness. The thickest panels achieve up to a 120-minute fire resistance rating, particularly critical in facilities such as nursing homes and hospitals where evacuation times may be prolonged.

6. Superior Acoustic Insulation
The panels deliver exceptional sound insulation performance, achieving up to 48 dB Rw (weighted sound insulation index). This acoustic capability enhances residential living quality and makes them ideal for partition walls in hotels, hospitals, schools, office buildings, and industrial spaces housing noisy equipment.

7. Moisture Resistance
The prefabricated walls exhibit strong moisture resistance due to their material composition. As a stone-based product, they resist rot, mold, and degradation—common issues with wood and drywall—making them suitable for humid environments. Additionally, they provide inherent rodent resistance.
