The process flow of a pillow hot melt adhesive production line typically includes the following steps:
Raw Material Preparation: The first step involves the preparation of the raw materials such as resins, waxes, and additives, which are used in the production of hot melt adhesives.
Mixing: In this step, the raw materials are blended in a mixer to ensure that they are thoroughly mixed and homogeneous.
Heating: The mixed materials are then heated to a high temperature until they melt and become fluid. The temperature and heating time vary depending on the specific formulation.
Filtering: The molten adhesive is then filtered to remove any impurities or foreign particles.
Coating: The filtered adhesive is then applied onto a substrate, such as a non-woven fabric, using a coating machine.
Cooling: The coated substrate is then cooled to solidify the adhesive and ensure that it adheres properly to the substrate.
Cutting and Shaping: The cooled substrate is then cut and shaped according to the required specifications of the final product.
Packaging: The final step involves packaging the hot melt adhesive pillows, which are ready for shipment and use.
Throughout the production process, strict quality control measures are implemented to ensure that the hot melt adhesive meets the required standards and specifications.
