Biomedical Blade Etching Machine
Wet chemical etching machine engineered specifically for surgical-grade blade and micro-needle production. Built on the same platform as our general wet etching lines, but with tighter temperature control, cleanroom-compatible wetted parts, and a process library tuned to medical-grade stainless steel, titanium, and nickel-based alloys. Manufactured by Xinxin Precision — an equipment manufacturer that is also a working etching factory, so every recipe shipped has been validated on our own production line.

Why This Equipment
- Built by people who run blade production every day — Xinxin Precision is an equipment maker AND a metal etching factory.
- Tighter temperature loop (±0.5 °C) than general-purpose etching machines, because medical-grade edge uniformity demands it.
- Cleanroom-compatible wetted parts and surfaces for downstream sterile assembly.
- Burr-free, stress-free, no recast layer — the as-etched edge is already at surgical quality.
- End-to-end blade manufacturing available as a service if you need finished blades rather than equipment.

What “Surgical-Grade” Means for the Equipment Design
Calling a machine “medical-grade” is meaningless without specifying what is different from a general-purpose etching line. On the Biomedical Blade Etching Machine, three things are tightened:
- Temperature control ±0.5 °C (vs. ±1.5 °C on a general line) — because surgical edge sharpness uniformity depends on the etch rate being constant within a single panel.
- Wetted parts polished and crevice-free — no biofilm-prone seams in the bath path.
- Filtered, deionized rinse water with conductivity logging — final rinse residue is a regulated parameter on medical device parts.
- Class-7 cleanroom integration option — so the equipment fits directly into an existing medical device cleanroom floor plan.

Frequently Asked Questions
What is the typical footprint?
Footprint ranges from a single-bench all-in-one unit up to 12 – 25 m floor length for a full production line. Layout drawings are part of the proposal package.
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.
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.
