FACTORY-DIRECT · ISO 13485 MANUFACTURER
Your Brand. Our Factory. Custom Tattoo Cartridges.
Build your own cartridge line on ISO 13485 certified production lines — without building a factory.
R&G Bio is an integrated manufacturer in Guangzhou, China. We run needle processing, injection molding, assembly, and sterile packing under one roof. For brand owners, that means one thing: you decide the specs, the look, and the packaging — we engineer and produce it. Custom needle groupings, gauges, membranes, housings, and full private label packaging, all EO gas sterilized and traceable by batch. Our in-house design and engineering team supports you from first sketch to repeat orders.
WHAT YOU CAN CUSTOMIZE
Every Part of the Cartridge, Open for Your Specs
From the needle tips to the retail box. Check what you need — we confirm feasibility and tooling cost in your quote.

PMU vs. Tattoo, Different Crafts
PMU and tattooing serve different purposes. PMU work calls for a softer, gentler needle action on delicate skin, while tattooing demands faster, more decisive color deposit. Same cartridge, different craft — needle tuning, taper, and membrane tension are all built to match the goal.
e.g. soft-tuned build for PMU, fast-saturation setup for tattoo work
💉
Needle Grouping
Any configuration: RL, RS, M1, M2, CM, RM, Bugpin, Hollow, Tight, Textured — plus custom needle counts.
e.g. custom 9RM arc, 19M1 stack
📏
Needle Diameter & Taper
Gauges from #04 to #12 (0.18–0.35mm), with long, medium, or short tapers to match your brand’s feel.
e.g. #10 with 3.5mm medium taper
🛡️
Membrane Structure
Membrane type, elasticity, and rebound tension tuned to your machines — soft for PMU pens, firm for rotary work.
e.g. high-elasticity silicone cone
🎨
Housing Color & Material
Shell and tip colors matched to your brand palette. Medical-grade polymer, translucent or opaque finish.
e.g. brand-color shell, clear tip
📦
Packaging
Custom blister cards, retail boxes, and master cartons. Our design team prepares print proofs for approval.
e.g. 10-pc box + 500-pc carton
💉
Logo Printing
Your logo on the cartridge shell, blister card, and box. Consistent brand mark across every unit.
e.g. 1-color logo on shell
🧫
Sterilization Labeling
EO gas sterilization for every unit, with sterilization indicator, batch number, and expiry date printed under your brand. Labels can carry your logo, your product codes, and your market’s required symbols — ready for import and retail checks.
