Product Overview
One-piece dispensing needles are integrated precision dispensing tips manufactured as a single solid unit. With seamless construction between the needle base and tube, they eliminate gaps and dead zones where glue may accumulate or cure. They deliver stable micro-dispensing performance, no leakage, and excellent repeatability for automated dispensing processes. Widely compatible with mainstream dispensers and syringe barrels in electronics, semiconductor packaging and optoelectronic industries.
Key Features
- Integrated one-piece structure: No assembly seam, no glue accumulation, effectively reduce clogging risk
- Smooth inner bore: Precision polishing, consistent flow rate, less glue stringing and dripping
- High concentricity & tight tolerance: Stable micro dot size for mass production
- Various tip options: Flat, tapered, angled and bevel tips available
- Multiple material choices: SUS304 / SUS316L stainless steel, tungsten carbide or ceramic tip for heavy wear applications
- Wide compatibility: Works with automatic dispensing valves, syringe barrels and Musashi dispensing systems

One-piece vs Split Type Dispensing Needle
表格
| Item | One-piece Dispensing Needle | Split Type Dispensing Needle |
|---|---|---|
| Structure | Integrated single piece | Detachable base + replaceable tip |
| Glue dead zone | Almost none, low clog risk | Minor gap at joint, higher clog risk |
| Maintenance | Replace entire needle once worn | Only replace tip, lower running cost |
| Cleaning | Harder for deep disassembly | Easy to take apart and clean |
| Precision & stability | Best for high-stable micro dispensing | Excellent for regular precision tasks |
| Best For | High cleanliness, high-volume micro-dot production | Frequent tip replacement scenarios |
