The PVC free foam board production line is a combination of equipment specifically designed for producing PVC free foam boards. The following is a detailed introduction to the PVC free foam board production line:

1、 Composition of production line
The PVC free foam board production line mainly consists of the following parts:

Conical twin-screw extruder: As the core equipment of the production line, it is used to heat, plasticize, and extrude PVC raw materials. The extruder uses specially designed screws to ensure sufficient plasticization and uniform foaming of the material.
Sheet metal mold: The material extruded by the extruder is molded into the initial shape of a sheet metal.
Forming table and cooling bracket: used for shaping and cooling extruded sheets to ensure their dimensional stability and surface flatness.
Tractor: Traction the sheet metal through the production line to ensure its smooth movement.
Cutting machine: Cut the shaped and cooled sheet into the required specifications.
Mechanical arm: Automatically picks up materials and neatly stacks cut boards, improving production efficiency.
In addition, the production line may also be equipped with other auxiliary equipment, such as mixers, storage hoppers, vacuum pumps, etc., to meet different needs during the production process.

2、 Production process flow
The production process of PVC free foam board is roughly as follows:

Raw material preparation: Mix PVC resin, foaming agent, stabilizer, lubricant and other raw materials evenly in a certain proportion.
Extrusion plasticization: The mixed raw materials are fed into a conical twin-screw extruder for heating and plasticization.
Mold extrusion: The plasticized material is extruded into the initial shape of a sheet through a sheet mold.
Shaping and cooling: The extruded sheet is shaped and cooled through a shaping table and cooling bracket.
Traction cutting: The traction machine pulls the sheet forward, and the cutting machine cuts it into the required specifications.
Stacking and packaging: The robotic arm automatically picks up the materials and neatly stacks the cut boards, then packages and stores them.
3、 Product Features and Applications
PVC free foam board has the following characteristics:

Lightweight and low density: Due to the use of foaming technology, the density of the board is low and the weight is light.
Poor hardness and good flexibility: The surface hardness is relatively low, but the flexibility is good, making it easy to process and shape.
Cheap price: Compared to other types of PVC boards, the price of free foam boards is more affordable.
PVC free foam board is widely used in the following fields:

Architectural decoration: such as ceiling, wall decoration, partitions, etc.
Advertising signs: such as promotional display boards, light boxes, signs, etc.
Furniture manufacturing: Furniture components such as cabinets and tabletops that require certain flexibility and lightweight requirements.
4、 Advantages of production line
High degree of automation: By adopting advanced automation equipment and control systems, the entire process of automated production from raw material input to finished product output has been achieved.
High production efficiency: The production line has high production efficiency and can meet the needs of large-scale production.
Stable product quality: By precisely controlling various parameters in the production process, the stability and consistency of product quality are ensured.
Energy saving and environmental protection: The production line adopts energy-saving equipment and technology, which reduces energy consumption and emissions and meets environmental protection requirements.
In summary, the PVC free foam board production line has the advantages of high automation, high production efficiency, stable product quality, energy conservation and environmental protection, which can meet the widespread demand for PVC free foam board in the market.
