Nordson® Series AD-31 handguns combine efficient design and reliable performance for manually dispensing hot melt adhesives, sealants and other thermoplastic materials. The wide selection of models satisfies a full range of applications, including packaging, assembly and sealing operations.
The series consists of various models for producing solid or foamed extrusion beads, spray patterns and swirl spray. For handling high-viscosity or filled materials, AD-31 LBS Extrusion handguns incorporate a large ball-and-seat and larger flow paths.
Designed with the operator in mind, lightweight AD-31 Extrusion and Swirl handguns weigh less than two pounds. A distinctive “ever-cool” handle contains no heated components or adhesive-flow paths that could cause discomfort to the operator. Heated gun components are totally enclosed within the exterior gun shell, helping to reduce the risk of burns.
Capable of standing up to the most demanding applications, AD-31 handguns feature an impact-resistant molded shell for extended service life. To eliminate hose twisting, AD-31 Extrusion and Swirl models feature a 360-degree swivel connector.
