Core Advantages of Single-Metal Dispensing Needles
In the dispensing needle market, besides single-metal materials, there are also plastic, metal-plastic composite, and other types. However, single-metal dispensing needles possess unique advantages that make them irreplaceable in precision applications:
Higher Dispensing Precision: The high rigidity of metal prevents tip deformation under pressure, maintaining a stable, preset aperture size. For instance, an ultra-fine 0.1mm needle tip will not “enlarge” over extended use, ensuring consistent adhesive volume and bead width with every dispense. This eliminates yield losses caused by tip deformation.
Enhanced Durability and Extended Lifespan: Unlike plastic needles prone to roughening from high-viscosity adhesives or composite needles susceptible to joint degradation, monolithic metal needles feature robust construction. Stainless steel variants, in particular, offer 3-5 times the lifespan of plastic counterparts, reducing long-term consumable replacement costs.
Wider Compatibility: Single-metal needles reliably dispense low-viscosity UV adhesives, high-viscosity epoxies, and even conductive adhesives containing fine particles. Their smooth metal interior prevents adhesive buildup and particle entrapment, while chemical resistance withstands adhesive corrosion—eliminating frequent needle changes for different materials.
Easier Cleaning: The seamless, single-metal construction requires only rinsing or soaking with compatible solvents (e.g., alcohol) to thoroughly remove adhesive residue. This design minimizes bacterial growth and impurity buildup, making it ideal for industries with stringent cleanliness requirements like medical and food packaging.
