Sterile needle ZPT-MNWNG-002

intradermalultra-fine25G

Product Overview
ZorayPT’s non-nickel gold-plated microneedle (Model ZPT-MNWNG-002) is a hypoallergenic precision device designed for safe and effective transdermal delivery in aesthetic and cosmetic applications. Engineered to eliminate nickel entirely, the product addresses skin-allergy and toxicity concerns in markets with strict nickel regulations. The variant uses a direct three-valent gold undercoating followed by 24K gold plating on a medical-grade stainless steel 304 or 316L (SUS304/SUS316L, customizable) base to provide a biocompatible, low-irritation surface suitable for sensitive skin treatments.

Design and Manufacturing
The design focuses on a nickel-free undercoating with three-valent gold and 24K gold plating to create a continuous conductive layer that enhances electrical properties for electro-microneedling while minimizing risk of nickel-induced reactions. The gold layer also contributes to antimicrobial properties and a premium finish that supports faster healing and improved serum penetration. Tip shapes (tapered, flat, round) and microneedle configurations (solid or hollow) are customizable to match treatment goals. The production process employs automatic cutting, automatic grinding, laser welding, acid cleaning, deactivation, and electrochemical polishing to achieve burr-free, polished inner and outer surfaces, ensuring smooth insertion and low resistance for patient comfort.

Quality Control and Packaging
Full magnification microscope inspections verify each needle for defects to meet rigorous skin-contact device standards. Microneedles are packaged in individual sterile blister packs (customizable to bulk packaging) to ensure sterility and readiness for clinical use. Lightweight and ergonomic integration reduces practitioner fatigue and allows precise control during extended sessions.
