S650 Knife Mold Etching Machine
Compact, plug-and-play all-in-one knife and mold etching machine for professional blade and small-mold customization. Designed to install on a single bench, power on, and run — no auxiliary utilities beyond standard 3-phase power and rinse water. Also available as a small-format nameplate etching machine for shop-floor customization and signage.
Why This Equipment
- Single-bench all-in-one — no separate developer, etcher, and rinse stations to coordinate.
- Plug-and-play installation — most customers are running production within hours of delivery.
- Built for short runs and customization — ideal for knife shops, custom-mold work, and shop-floor signage.
- Low operating cost — small bath volume keeps chemistry consumption predictable.
- Easy chemistry change-over for shops running multiple metals on the same equipment.

Design Priorities & Process Discipline
The platform is engineered to four priorities: bath chemistry stability, conveyor uniformity, spray-pressure uniformity, and rinse cascade discipline. In practice it is the temperature loop and the spray nozzles that move output yield from 95% to 98%; everything else is supporting infrastructure.
- Closed-loop bath chemistry — SG and pH sensors feed a replenishment manifold.
- Dual-bank nozzles — independent top and bottom spray for double-sided etching uniformity.
- Conveyor traceability — sheet-by-sheet ID logged with bath conditions for QA.
- Acid-resistant wetted parts — PVC, PVDF, or Hastelloy C-276 depending on chemistry.
- Energy recovery — heat exchanger between hot rinse exit and cold feed water reduces line steam demand.

Frequently Asked Questions
Can the machine be retrofitted later?
Yes — wetted-parts upgrades (e.g. FeCl₃ → HF-compatible) and additional stages are planned-shutdown retrofits.
Is the machine customized to my production line?
Yes. Every system is built around your panel size, throughput target, available utilities, and downstream process integration — not sold as a fixed SKU.
Where are these machines manufactured?
Equipment is manufactured by Xinxin Precision, who is also a working metal etching factory — meaning every chemistry and process shipped has been validated on our own production line first.
What is the typical lead time from order?
Production lead time is typically 8 – 14 weeks depending on configuration. Plug-and-play bench units are usually available faster.
