What is Precast Boundary Wall Making Machine？
The precast boundary wall making machine is a specialized piece of equipment designed for producing lightweight, non-load-bearing concrete wall panels — including hollow core and solid types. This machine uses an extrusion process to compress and shape concrete materials within a mold, forming uniform and durable boundary wall panels.
Kelai’s high-frequency extruder model features semi-automatic or fully hydraulic lifting systems, enabling continuous production speeds of 2 to 3.5 meters per minute, with a daily output of up to 500 square meters. The resulting wall panels offer excellent thermal insulation, sound insulation, and seismic resistance, making them ideal for modern construction needs.
These precast panels are widely used as external boundary walls and partition walls in various structural systems, including steel-concrete frames and steel structures. They are especially suitable for residential buildings, office complexes, commercial facilities, and other urban development projects that demand fast, clean, and energy-efficient construction methods.
Precast Boundary Wall Making Machine Main Features:
Efficient production: The extruded wall panel machine can efficiently mix and extrude lightweight concrete raw materials evenly, and the production speed is greatly improved compared with the traditional method.
Combination of light weight and high strength: The wall panels produced are not only light in weight, easy to transport and install, but also have high strength to meet the safety requirements of the building.
Energy saving and environmental protection: The machine uses lightweight concrete, and the finished wall panels have good thermal insulation, which can effectively improve the energy efficiency of the building and reduce the energy consumption of air conditioning and heating.
High precision: The equipment can accurately control the density of the concrete and the thickness of the wall panels to ensure that the size and quality of each precast wall panel are consistent.
High degree of automation: The precast lightweight concrete wall panel machine has automatic unloading, vibration, extrusion and demoulding functions, reducing labor costs and improving production efficienc
Precast Concrete wall panel machine Forming principle
This lightweight precast concrete wall panel 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 precast wall panels will be very smooth and compact.

Precast wall panel extruder structure
This machine integrates multiple processes—including feeding, vibration, forming, and demolding—for lightweight partition panel production into a single unit. The main motor transmits power to the gearbox via a pulley system, and the gearbox’s output shaft drives the augers to rotate within the forming cavity, which is formed by the machine frame (wall plates), vibrator (vibrating body), and casting bed.
The lightweight mixture from the hopper is continuously conveyed into the forming cavity. Here, under the dual action of auger extrusion and continuous compaction from the vibrator, the mixture reaches resonance, becoming thoroughly compacted and shaped to the required dimensions and density. Simultaneously, the compacted panel exerts a reactive force against the rotating augers, pushing the extruder continuously forward to achieve seamless, ongoing panel production. Finally, a forming scraper at the rear of the machine smoothes and finishes the top surface of the board.

Raw Materials and formula for Finished 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+normal 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.
