1、 Overview of Production Line
The semi skinning foam board production line combines the advantages of free foaming process and skinning foaming process, and has the characteristics of simple equipment and tooling, simple formula, and low difficulty in process operation. This production line melts and extrudes raw materials through an extruder, and then undergoes a series of processing techniques to finally obtain semi laminated foam boards with low density, high surface hardness, and good flatness.

2、 Composition of production line
The semi laminated foam board production line mainly consists of the following parts:

Extruder: responsible for melting and extruding raw materials into shapes. Extruders usually use parallel twin-screw structures in opposite directions, which can provide good mixing effects and extrusion stability.
Mold: The design of the mold is crucial for the molding quality of the semi laminated foam board. It determines the shape, size, and surface quality of the board.
Shaping device: The shaping device is used to cool and shape the extruded sheet, ensuring its dimensional stability and physical properties. The shaping device usually includes a vacuum shaping table and a shaping plate, etc.
Traction device: The traction device is used to pull the cooled and shaped board out of the production line and perform winding or cutting.
Cutting device: Cut the board according to the required length and width to meet the needs of different customers.
Control system: The control system is responsible for the automation control of the entire production line, including temperature control, speed control of the extruder, tension control of the traction device, etc.
3、 Product Features
Half crust foam board has the following characteristics:

Low density: The semi laminated foam board has a low density, is lightweight, and is easy to process.
High surface hardness: Using Celuka technology for foaming, the surface layer is smooth and flat, with a high degree of skin hardness and stiffness.
Good flatness: By precise mold design and control of the shaping device, high flatness sheets can be obtained.
Waterproof and flame retardant: Semi laminated foam board has good waterproof and flame retardant properties, suitable for applications in various humid and high-temperature environments.
Acid and alkali resistant and anti moth: It can resist the erosion of chemical substances such as acid and alkali, and has excellent anti moth performance.
