T/SDWJ 004-2022 Heat-sealing gun

Scope

Scope: This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage of glue guns. This standard applies to various components packaged in hard tubes with an outer diameter ≤50mm, an inner diameter ≥40mm, a length ≤220mm, a capacity of 330ml, and a maximum diameter of the glue nozzle ≤28mm, used for low-viscosity glue dispensing. Main technical contents: 3. Requirements 3.1 Appearance quality 3.1.1 The surface of sheet metal parts and stamped parts shall be free from heavy skin, obvious mechanical damage, and unevenness. 3.1.2 The plating and coating shall be uniform in color, without obvious peeling, bubbling, or scratches. 3.1.3 Welded parts shall be uniform, without cracks, burn marks, or undercuts; the welded surface between the fixed screw and the handle shall be smooth. 3.1.4 Forged and cast parts shall be free from flow marks, missing materials, cracks, bubbling, or peeling. 3.2 Performance requirements 3.2.1 Operational performance: The glue gun should be able to dispense glue smoothly during normal use. 3.2.2 Drop test performance: After the drop test, the glue gun should still be able to dispense glue normally. 3.2.3 Punching force during glue dispensing: The punching force during glue dispensing should be between 800N and 1200N. For aluminum tube-type glue guns, the punching force should be 1500N. 3.2.4 Centering: The glue gun's push rod should be able to insert and withdraw smoothly. The push rod should be parallel to the left and right ribs, and the head of the push rod should not tilt during the pushing process. Before the push rod reaches the top ring, the pushing plate should not deviate by ±3mm. 3.2.5 Impact resistance of the handle: After the impact test, the handle should not suffer from mechanical damage or breakage. 3.2.6 The number of pushing steps should not exceed 27 times.
