These high-precision stainless steel needles undergo advanced processing—including precision internal and external polishing and multiple ultrasonic cleaning cycles—to completely eliminate burrs and ensure a pristine interior that will not contaminate the adhesive. The needle-to-hub junction utilizes an advanced bonding process combined with high-strength UV adhesive, guaranteeing a secure connection that will not fail.
The hub features a wide, flat screw-on design that mates precisely with the syringe barrel, ensuring a smooth, rapid dispensing process and absolute safety at pressures up to 12 kg. The specialized hub material blocks UV light, preventing the waste of expensive UV adhesive within the needle during production.
