 | Introduction of Mat Forming Machine Line |
Mat forming machine is one important equipment for making OSB(Oriented Strand Board), MDF (Medium Density Fiberboard), and Particleboard /chipboard, its function for laying the glued wood shavings and strands and fibers on the continuous conveyor belt.
Now in the market, the mainly mat forming machine is mechanical mat forming machine and air mat forming machine or combination type
So do you know the Difference between Mechanical type and Air-flow type forming line?
★ Mechanical Mat Forming Machine
√ Working Principle
The raw materials are suspended and conveyed to the paving belt by air flow (positive pressure or negative pressure), and the uniformity of raw material drop is controlled by the distribution of air flow
Particleboard: Different particle sizes of particleboard are separated by air flow, achieving a gradient laying of fine materials on the surface layer and coarse materials on the core layer.
MDF: Negative pressure adsorbs fibers to form a highly uniform and non-directional fiber layer
√ Typic Structure
○ Roller type: Multiple sets of high-speed rotating rollers are arranged horizontally. After the wood shavings are scattered, they fall freely.
○ Sweeping arm type: The reciprocating sweeping arm evenly spreads the fibers (commonly seen in early MDF production lines).
○ Directional roller (OSB dedicated) : A roller with grooves enables the directional arrangement of long wood shavings.
√ Advantages
○ It has a simple structure and low maintenance cost.
○ Low energy consumption (no need for a complex air flow system).
○ Suitable for coarse wood shavings (such as the core layer material of OSB)
〤Disadvantages
○ Poor uniformity: Local accumulation or voids are prone to occur, affecting the consistency of the board density.
○ Weak layering control: It is difficult to achieve a fine surface-core layering structure of particleboard.
○ The orientation accuracy is limited (multiple calibrations are required in OSB production)
√ Application
○ suitable for Low-density particleboard, OSB core layer laying, early MDF production line
★ Air flow Forming machine
√ Working Principle
The raw materials are suspended and conveyed to the paving belt by air flow (positive pressure or negative pressure), and the uniformity of raw material drop is controlled by the distribution of air flow.
○ Particleboard: Different particle sizes of particleboard are separated by air flow, achieving a gradient laying of fine materials on the surface layer and coarse materials on the core layer.
○ MDF: Negative pressure adsorbs fibers to form a highly uniform and non-directional fiber layer
√ Typic Structure
○ Negative pressure adsorption type (mainstream MDF) : Vacuum boxes are set under the paving tape, and the fibers are adsorbed onto the surface of the tape.
○ Positive pressure jet type: The air flow blows the raw materials towards the paving tape, and the thickness is adjusted in combination with the baffle.
○ Layered air flow system (particleboard) : Multiple air flow channels separate coarse and fine wood chips
√ Advantages
○ Excellent uniformity of laying: The dispersion of air flow makes the distribution of raw materials more continuous, and the density deviation of the board can be controlled within ±2%.
○ Precise layering: Air flow screening achieves a gradient structure of particleboard (fine surface layer and loose core layer).
○ Suitable for fine materials: Especially suitable for MDF fibers or fine particles on the surface of particleboard
〤Disadvantages
○ High energy consumption: Large fans and dust removal systems need to be equipped, resulting in significant power consumption.
○ Complex maintenance: The air flow ducts are prone to clogging and need to be cleaned regularly.
○ Raw material limitations: Poor adaptability to overly coarse or overly wet raw materials (for example, OSB long wood shavings may tangle)
√ Application
○ High-precision MDF, high-end particleboard (especially furniture boards that require fine surfaces)
★ Key Comparison of Both Mat Forming Machine
| Items | Mechanical Mat Forming | Air-Flow Mat Forming |
| Medium (Rely on mechanical dispersion accuracy) | Forced dispersion of air flow | |
| Energy consumption | Low (mechanical power) | High (The air flow system consumes a large amount of electricity) |
| Layering | Weak (requires additional screening equipment) | Strong (built-in airflow stratification. |
| Raw material adaptability | Suitable for coarse materials (such as OSB core layers) | Suitable for fine materials (MDF fibers, surface wood shavings) |
| Maintenance cost | Low (mechanical parts are easy to replace) | High (The air flow system is clean and complex |
| Application | Ordinary particleboard, OSB directional laying | High-end particleboard, homogeneous MDF |
★ Electric system for our Continuous Press
Siemens brand PLC
Siemens electric control cabinet
Our continuous press with Siemens brand PLC and electric parts, ensure it works very well.
★ Advisement
○ Give priority to the mechanical type:
The production of OSB or low-density particleboard involves coarse raw materials and is cost-sensitive.
The power capacity of the factory building is limited and energy consumption needs to be reduced.
○ Give priority to the air flow type:
Produce particleboard or homogeneous MDF with high surface quality.
The raw materials are fine fibers or micro-fine wood shavings, and extreme uniformity is required
