• Wire Drawing: Raw steel rod is drawn through a series of dies, progressively reducing its diameter to the desired wire gauge while simultaneously increasing its tensile strength. This ensures the staple possesses the necessary rigidity to penetrate carton material effectively.
• Cleaning and Coating: The drawn wire is thoroughly cleaned to remove impurities. It then undergoes a coating process, such as galvanization for general corrosion resistance or copper-plating for enhanced lubricity, rust prevention, and visual distinction, as seen in the 3215 Copper Pneumatic Carton Closing Staples.
• Forming and Cutting: Coated wire is fed into high-speed forming machines that precisely bend it into the staple's U-shape (crown and legs) and cut it to the exact leg length. The precision of this step is critical for consistent performance in pneumatic staplers.
• Adhesive Application: A specialized adhesive is applied to the formed staples, binding them together in a coherent strip or stick. This adhesive is designed to hold the staples together during handling and loading, yet easily break apart upon firing by the stapler, ensuring smooth operation.
• Quality Inspection: Throughout the entire manufacturing process, stringent quality checks are implemented. This includes visual inspection, dimensional measurement (crown width, leg length, wire gauge), and functional testing for tensile strength, shear strength, and penetration capability. Adherence to standards such as ISO 9001:2015 ensures consistent product quality and reliability. The typical lifespan of a staple, once applied, is dictated by the durability of the carton itself, often exceeding the required transit time due to its inherent anti-corrosion properties and secure hold.
