Do You Understand Precast Concrete Wall Panel Machines?

Extrusion Type of Precast Lightweight Concrete Wall Panel Machines

In the modern construction industry, precast concrete wall panel machines are revolutionizing how buildings are designed and built. Among them, concrete wall panel extrusion machines are leading the innovation due to their superior performance, production efficiency, and ability to produce high-quality, lightweight panels for internal and external use.

At Henan Kelai Industrial Co., Ltd., we were among the first in China to develop, design, and manufacture extrusion-type precast lightweight concrete wall panel machines. These advanced machines operate on a completely different principle than traditional pulling mold machines, pushing systems, or vertical casting machines.

What Makes Concrete Wall Panel Extrusion Machines Different?

Unlike traditional systems that rely on pulling or molding, concrete wall panel extrusion machines utilize a forward-extrusion method to shape the panel while maintaining consistent density and surface smoothness. This extrusion method ensures that every panel produced has:

A smooth, wrinkle-free surface
A compact and dense core
High compressive strength
Minimal material waste during production

These machines are especially suitable for companies aiming for high-volume, standardized production in prefabricated housing, commercial buildings, or modular construction.

Working Principle of the Extrusion-Type Wall Panel Machine

The structure of the precast concrete wall panel extrusion machine is straightforward yet highly efficient. It is composed of three main systems:

Power System:
Powered by a 5.5 to 11 kW motor, which drives the machine via a durable gearbox.
Extrusion System:
Consists of multiple high-speed augers (3–20 depending on the panel size and cavity type). These augers compact and transport the concrete mixture into the forming mold with precision and consistency.
Vibration System:
Located above the mold cavity, the high-frequency vibration motor ensures complete compaction through repeated tamping, removing air pockets and improving panel strength.

As the machine moves forward, the combination of extrusion and vibration continuously forms panels behind it—an automated process ideal for uninterrupted production lines.

Compatible Raw Materials for Lightweight Panel Production

One of the advantages of Kelai’s concrete wall panel extrusion machines is their flexibility in raw material use. They support both ordinary concrete and lightweight concrete—without the need for foamed agents—making the machines highly adaptable across different regions and material supply chains.

Common raw materials include:

Ordinary Concrete: Cement, sand, fly ash, crushed stone
Lightweight Concrete Aggregates:
- Industrial waste (slag, recycled concrete)
- Volcanic rocks
- Ceramsite
- Shale
- Expanded perlite
- Pumice

It’s important to note that panels made with ordinary concrete are typically 30–40% heavier than those made with lightweight aggregates. Depending on the local availability and building requirements, customers can select the most economical and suitable mix design.

Types and Applications of Finished Wall Panels

Wall panels produced by our precast lightweight concrete wall panel machines can be:

Hollow or solid in structure
Non-load-bearing, ideal for partition walls in frame structures

Common application scenarios:

Residential buildings (apartments, villas)
Commercial buildings (shopping centers, office spaces)
Hospitals and schools
Industrial workshops
Precast boundary walls
Foundation formwork or fencing systems

Available dimensions (customizable):

Width: Standard 600 mm
Thickness: 60 mm to 200 mm (common sizes: 60, 75, 90, 100, 120, 150, 200 mm)
Length: Can be cut to meet building height requirements

We also support fully customized concrete wall panel extrusion machines to produce different panel widths or thicknesses according to specific project requirements.

What About the Price of Concrete Wall Panel Machines?

Pricing is one of the most common concerns. The price of a precast concrete wall panel machine varies depending on:

The type of machine (extrusion, vertical mold, pushing system)
Desired panel thickness and output capacity
Automation level
Auxiliary equipment and customization level

We offer flexible, scalable solutions with full customization options. Whether you’re starting a small precast production plant or expanding a large prefab facility, we can tailor a production line that matches your goals and budget.
