Chemical Etched Beauty Micro-Needles for US Aesthetic & Medical Markets

Beauty Needle Overview
Xinhaisen Technology is a leading manufacturer of precision metal parts for the medical and aesthetic industries. We produce ultra-fine beauty needles and microneedling parts using advanced chemical etching technology. This process guarantees exceptional sharpness, perfect consistency, and absolute safety for professional skincare and therapeutic applications. Our parts are known for their reliability and performance.

Manufacturing Process

Our beauty needles are fabricated using advanced photochemical etching (PCE), a subtractive manufacturing process ideal for delicate, high-tolerance metal parts.

• Material Selection & Cleaning: We start with premium surgical-grade stainless steel or other specified alloys, thoroughly cleaned to ensure perfect adhesion of the photoresist.

• Photoresist Lamination: A light-sensitive polymer film is laminated onto the metal sheet.

• Precision Exposure: The sheet is exposed to UV light through a high-precision photographic tool, transferring the complex needle array design onto the material.

• Development & Etching: The unexposed photoresist is washed away, and the unprotected metal is precisely etched away using a controlled chemical bath. This process creates perfectly smooth, sharp edges without mechanical stress or burrs.

• Stripping & Finishing: The remaining photoresist is removed. Components undergo stringent quality control, including precision cleaning, optional electropolishing for enhanced smoothness, and sterilization-ready packaging.

FAQ

Q: What are the benefits of etched needles over traditionally stamped or ground needles?
A: Etched needles are inherently burr-free, have superior dimensional consistency, and allow for more complex geometries without tooling wear, resulting in a safer, more comfortable patient experience.

Q: Can you handle specialized materials for biocompatibility?
A: Yes. We routinely work with ASTM-grade stainless steels (like 316L), titanium, and other alloys. We can advise on material selection for your specific certification needs.

Q: What is your lead time for prototypes and mass production?
A: Prototype lead times are typically very short (days/weeks). For mass production, we are renowned for our speed and flexibility to handle both standard and large-volume orders efficiently.

Q: Do you offer custom design services?
A: Absolutely. Our engineering team can collaborate with you to optimize your design for manufacturability, performance, and cost from the initial concept stage.

Q: How do you ensure quality control?
A: We employ rigorous in-process inspections using optical measurement systems and coordinate measuring machines (CMM) to ensure every batch meets our strict tolerance standards.
