Selective Wave Soldering Nozzle H47 For Ersa, ZSW, AST Machine

SMT Selective Soldering Nozzle | SMT Spare Part Compatible with Ersa, ZSW, AST Selective Wave Soldering Machines

Our precision selective soldering nozzles are essential consumable components for selective wave soldering production lines, perfectly interchangeable with Ersa, Zhishengwei (ZSW), AST and other mainstream selective soldering equipment brands.
We stock a full lineup of standard sizes: 3–6-H47, 4–8-H47, 5–9-H47, 8–12-H47, 10–14-H47, 12–16-H47, 16–20-H47 to satisfy diverse PCB through-hole soldering demands. Beyond standard sizes, we offer professional NON-STANDARD CUSTOMIZATION service. Our engineering team can fabricate custom nozzles according to your technical drawings, samples or special production parameters, covering customized inner diameter, outer diameter, length, taper shape and surface coating requirements.

Each nozzle undergoes precise CNC machining and is treated with a high-performance special anti-tin coating. The advanced coating features strong adhesion and excellent durability, effectively resisting peeling or flaking under prolonged high-temperature operating cycles.
This premium surface treatment delivers multiple core production benefits:
✅ Superior corrosion resistance against molten solder, flux and high-temperature oxidation
✅ Ultra-smooth inner surface enables consistent, smooth tin flow during selective soldering
✅ Stable solder stream, minimizing deflection, offset flow and tin splashing
✅ Greatly reduces common defects such as bridging, cold joints and pinholes on PCBs

Constructed from high-temperature resistant alloy substrate, our nozzles maintain stable mechanical performance under continuous long-run production conditions, resisting deformation, abrasion and premature aging. Strict dimensional tolerance control ensures seamless fitting with your selective soldering machine heads, eliminating leakage and inconsistent soldering results.

These nozzles are widely adopted in SMT electronics assembly, automotive control PCBs, consumer electronics, medical device circuit boards, industrial automation modules and aerospace small-batch precision soldering applications.
All standard models are kept in sufficient inventory for quick shipment. Every product passes rigorous dimensional, surface and coating inspection before delivery to guarantee uniform quality. For bulk orders or customized non-standard nozzles, we provide competitive volume pricing, dedicated technical consultation and fast sample development support to shorten your lead time.
