Hot melt pressure sensitive adhesives (PSAs) play a vital role in various industries, offering a convenient and versatile bonding solution. These adhesives are characterized by their ability to form an instant and strong bond upon application of pressure, eliminating the need for solvent-based or water-based adhesives that require drying time. The manufacturing process of hot melt pressure sensitive adhesives (PSAs) involves several steps to create a formulation, mix the components, and ensure quality control.

An automatic hot melt extrusion feeding system is a specialized equipment used in hot melt pressure-sensitive adhesive (PSA) manufacturing to automate the feeding and dosing of materials into the extrusion process. This system ensures a continuous and precise supply of adhesive components to the extruder, improving efficiency and consistency.
A hot melt PSA vacuum system is a component used in the manufacturing process to create a vacuum or negative pressure environment. It is primarily employed for degassing purposes, removing air bubbles, and eliminating volatile components from the hot melt pressure-sensitive adhesive (PSA) formulation.
A hot melt PSA mold temperature machine, also known as a mold temperature controller or mold temperature control unit, is a specialized equipment used in the manufacturing process to regulate and maintain precise temperature control during the molding of hot melt pressure-sensitive adhesives (PSAs). It ensures consistent and controlled cooling of the adhesive in the mold, optimizing the molding process.
A hot melt PSA bag filter is a filtration system used in the manufacturing process of hot melt pressure-sensitive adhesives (PSAs). It is designed to remove impurities, contaminants, and particulate matter from the adhesive formulation, ensuring a clean and high-quality final product.
The hot melt PSA (pressure-sensitive adhesive) discharge/packaging system is a crucial component of the manufacturing process that facilitates the transfer of the adhesive from the production equipment to the final packaging containers. It ensures efficient, accurate, and controlled filling, sealing, and packaging of hot melt PSAs.
Textile: Block hot melt glue is also used in the textile industry for applications such as fabric bonding and hemming. It can be used to bond a variety of fabrics, including polyester, nylon, and cotton.
Automotive: Block hot melt adhesive is used in the automotive industry for a variety of applications, including interior trim bonding, headlamp assembly, and under-the-hood applications.
