Principle Of PVC Edge Banding

The principle of PVC edge banding mainly includes the following steps:

Raw material preparation and mixing: First, according to the product performance requirements, select and prepare the appropriate amount of raw materials such as PVC resin, plasticizer, stabilizer and filler. After these raw materials are inspected for quality, they are evenly mixed in the mixer according to the formula ratio. During the mixing process, temperature control is crucial to prevent the raw materials from chemically reacting or decomposing at high temperatures.

Extrusion molding: The mixed PVC material is fed into the extruder, heated and pressurized, and melted and plasticized to form a continuous molten material. The molten material is extruded into edge banding of a specific shape and size through the screw of the extruder.

Cooling and trimming: The extruded edge banding then enters the cooling zone and is quickly cooled by the cooling device to solidify it and keep its shape stable. The cooled edge banding will undergo a trimming process to remove excess corners and uneven parts to ensure the appearance quality of the edge banding.

Quality inspection and packaging: PVC edge banding that has passed the quality inspection will be packaged for storage and transportation. The entire production line achieves coordinated work in all links through an automated control system to ensure the continuity and stability of the production process.
