Precast Concrete Panel Machine: Working Principle and Manufacturing Process Explained
As construction projects around the world demand faster delivery, better quality, and lower costs, precast concrete panels have become a preferred building solution. But how exactly are these panels made? And what role does the precast concrete panel machine play in the production process?Precast concrete panel machine working principle will tell you ！
At Henan Kelai Industrial Co., Ltd., we’ve been manufacturing advanced precast concrete panel machines for over 20 years. In this article, we explain the working principle, machine components, and panel production process so you can better understand how to invest in and operate these powerful machines.
🔧 What Is a Precast Concrete Panel Machine?
A precast concrete panel machine is industrial equipment used to produce concrete wall panels in a controlled environment. These panels are cast, cured, and prepared off-site (in a factory), and then transported to the construction site for fast assembly.
Kelai’s panel machines are designed to produce:
- Solid wall panels
- Hollow core panels
- Lightweight sandwich panels
- Composite Acotec panels
- Partition or load-bearing walls
Each type of machine is built to match specific panel thickness, material mix, and output capacity.
⚙️ Working Principle of Precast Concrete Panel Machines
Though panel machines can differ by type, the core working principle follows this sequence:
1. Material Preparation and Feeding
The process starts with raw materials such as cement, sand, stone, lightweight aggregates (e.g., EPS or ceramsite), and water. These materials are automatically batched, mixed, and delivered to the machine’s hopper.
2. Panel Forming and Shaping
Once the mixture enters the mold chamber, the machine uses high-frequency vibration, hydraulic compaction, or screw extrusion (depending on model) to shape the material into panel form.
Kelai’s extrusion-type machines are ideal for producing long continuous panels on a steel platform, which are later cut into specified lengths.
3. Panel Cutting
Once formed, the panels are automatically or manually cut to the desired length using a cutting system integrated with the machine or placed alongside.
4. Demolding and Stacking
After initial curing or setting, panels are carefully demolded and stacked using lifting equipment or conveyors. Some machines offer auto-stackers to increase efficiency.
5. Curing
Panels are moved to a curing area or curing room where they gain strength over 8–24 hours. Accelerated curing using heat or steam is optional, depending on the project.
🏭 Machine Components Overview
A complete precast concrete panel production line includes:
- Material batching and mixing system
- Conveying system (screw or belt type)
- Forming/extrusion machine
- Hydraulic or mechanical mold press (if applicable)
- Cutting device
- Mold platform or forming table
- Curing rack or room
- Control panel / PLC system
All components work together to ensure continuous, precise, and scalable panel production.
