View detailsBiomedical 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.
Frequently Asked Questions
Can the Biomedical blade etching machine manufacturing equipment be customised for our process?
Yes. Conveyor width, tooling, control options, and the surrounding handling can be adapted to your panel size, throughput target, and facility constraints. Share your specification and we will propose a configuration.
What level of automation does the Biomedical blade etching machine manufacturing equipment offer?
Operation is recipe-driven through an operator interface, with process values logged so that results stay repeatable across shifts and operators.
What facility connections does the Biomedical blade etching machine manufacturing equipment need?
Electrical, compressed-air, water, and exhaust requirements are confirmed in the installation drawing we issue before delivery, matched to your facility's available services.
What workpiece sizes does the Biomedical blade etching machine manufacturing equipment handle?
Working size depends on the configured tooling and conveyor width. Share your largest and smallest part dimensions and we will confirm the achievable window.
