Frequently Asked Questions

Q1: Are these dispensing needles compatible with main brand dispensers?

Yes, our dispensing needles feature universal Luer slip/lock fittings (ISO 594) and are fully compatible with industry-standard dispensers such as Nordson, EFD, and Musashi systems.

Q2: What material options do you offer for abrasive materials?

For highly abrasive fillers, we recommend our Tungsten Carbide tips, which provide 5X the wear resistance of standard steel. We also offer PTFE-coated needles for non-stick UV-curable adhesive applications.

Q3: Do you provide needles for static-sensitive electronics assembly?

Yes, we provide ESD-safe and anti-static needles specifically designed for conductive adhesives and components sensitive to static electricity.

Q4: What is the minimum internal diameter (ID) you support?

Our Ultra-Fine Series (34G-27G) offers inner diameters ranging from 0.1mm to 0.3mm, ideal for micro-dot dispensing and high-precision chip bonding under microscopy.

Q5: Can these needles operate under high temperatures?

Yes, we offer specialized heatable needles capable of maintaining temperatures between 80°C and 200°C (with peak resistance up to 250°C for PTFE-coated variants), which are ideal for hot-melt dispensing.

Q6: What precision tolerances do your dispensing tips maintain?

Our needles feature an inner diameter tolerance of ±0.01mm for sizes 18G-34G, a tip concentricity runout of less than 0.05mm, and a mirror-finish surface roughness of Ra 0.1μm to ensure smooth fluid flow.
