For specific applications, other coatings like copper plating or vinyl coating may be applied.
3. Adhesive Application: Several strands of the treated wire (typically 50-200 depending on packaging) are laid parallel and coated with a specialized thermoplastic adhesive. This adhesive is crucial for binding the individual staples into coherent strips, which are essential for smooth feeding in pneumatic tools. The adhesive is designed to activate upon impact or friction during firing, ensuring the staples separate cleanly.
4. Forming and Cutting: The adhesive-bound wire strip is then fed into a high-speed forming machine. Here, specialized dies bend the wire into the distinctive U-shape of the 90 series staples, creating the crown and legs. Simultaneously, a cutting mechanism precisely severs the formed staples to the desired leg length (e.g., 18ga narrow crown staples 10 38mm). Precision in this stage ensures uniform dimensions and optimal performance.
5. Curing and Packaging: After forming and cutting, the staple strips undergo a curing process, often involving heat, to fully set the adhesive. This strengthens the bond within the strip while allowing individual staples to detach cleanly during application. Once cured, the strips are carefully inspected, counted, and packaged into boxes or larger cartons, ready for distribution.
6. Quality Control and Testing Standards: Throughout the entire manufacturing process, stringent quality control measures are implemented. This includes:
   • Material Analysis: Verification of raw wire composition and tensile strength (e.g., ASTM A510).
   • Dimensional Accuracy: Regular checks of wire gauge, crown width, and leg length using precision calipers and optical measurement systems. Compliance with ISO 9001:2015 standards for quality management.
   • Adhesion Strength: Testing the integrity of the staple strips to ensure they do not break prematurely during handling or shipping, but also separate cleanly during firing.
   • Corrosion Resistance: Salt spray tests (e.g., ASTM B117) for galvanized staples to ensure coating efficacy and predicted service life.
   • Performance Testing: Random samples are tested in various pneumatic tools to confirm smooth feeding, jam-free operation, and consistent penetration.

This rigorous process ensures that each batch of 90 series staples meets the highest industry standards, delivering exceptional performance, extended service life, and reliable operation in demanding B2B environments.
