Raw material handling: The raw materials for hot melt adhesive production are typically stored in silos or drums and are transferred to the production line through a conveying system.
Melting: The raw materials are melted in a large vessel or tank, where they are heated to a specific temperature and mixed together to form a homogeneous mixture.
Filtering: The melted adhesive mixture is then passed through a filter to remove any impurities or particles that may have been introduced during the melting process.
Addition of additives: Various additives such as colorants, tackifiers, and stabilizers are added to the melted adhesive mixture to improve its properties.
Homogenization: The mixture is then homogenized to ensure that all the ingredients are evenly distributed.
Application: The hot melt adhesive is applied to a substrate using a variety of application methods, such as spraying, extrusion, or roller coating.
Cooling: The substrate with the applied adhesive is then cooled to solidify the adhesive and ensure that it bonds properly with the substrate.
Cutting: The substrate is then cut into the desired shape or size, depending on the application.
Packaging: The final product is then packaged and labeled for shipping or storage.
Note that the specific process flow may vary depending on the type of hot melt adhesive being produced and the equipment used in the production line.
