Product Overview

Xinhaisen specializes in manufacturing high-precision beauty needles microneedles using advanced chemical etching technology. These ultra-fine metal parts are essential for modern aesthetic treatments including microneedling, mesotherapy, and cosmetic tattooing.Our precision etching process produces needles with exceptional sharpness and dimensional accuracy, ensuring minimal patient discomfort and optimal treatment results. Trusted by medical device manufacturers and aesthetic clinics worldwide, Xinhaisen delivers the precision required for professional dermatological and cosmetic applications.

What is Chemical Etching?

Chemical etching, also known as photo chemical machining or acid etching, is a precision manufacturing process that uses chemical reactions to create complex metal parts without mechanical force or heat.

The process involves:

• A high-grade metal sheet is coated with a light-sensitive photoresist material

• A precisely designed tooling film with the needle pattern is applied

• UV light exposure hardens the photoresist in the desired pattern

• Specialized chemicals dissolve the unprotected metal areas

• The remaining photoresist is removed, leaving burr-free precision needles

This method allows us to achieve tolerances and complexities impossible with conventional machining, making it ideal for the micro-sized features required in beauty and medical devices.

Product Features

• Ultra-Precision Tips
  Our etching process creates tips with micron-level sharpness, ensuring smooth skin penetration and minimal tissue trauma compared to stamped or laser-cut alternatives.
• Burr-Free and Stress-Free
  Because the metal is chemically dissolved rather than mechanically cut, the needles have no burrs, micro-cracks, or residual stresses. This eliminates the risk of skin damage and ensures structural integrity during use.
• High Consistency and Uniformity
  The photochemical process guarantees every needle in a batch is identical. This uniformity ensures predictable penetration depth and consistent treatment results for end users.
• Material Versatility
  We process various high-grade biocompatible metals, allowing customization based on strength, flexibility, and corrosion resistance requirements.
• Customizable Geometries
  Specific tip angles, unique array layouts for roller devices, or specific lengths are available through our flexible tooling process without the high cost of physical molds.
• Smooth Surface Finish
  Post-etching treatment options such as electropolishing provide an ultra-smooth surface that reduces skin drag and is ready for sterilization.

Frequently Asked Questions

• What materials do you use for beauty needles?
  We primarily use medical-grade stainless steel 316L and titanium Grade 2 or Grade 5. Both materials are highly biocompatible, corrosion-resistant, and suitable for repeated sterilization processes.
• Can you customize the needle array pattern for my device?
  Yes. Our photo chemical etching process is extremely flexible. We can produce custom layouts, needle densities, and specific shapes based on your two-dimensional CAD drawings or design requirements for any device type.
• What is the minimum order quantity?
  We cater to all scales of production. We support low-volume prototyping for research and product testing as well as mass production for large-scale commercial launches. Please contact us with your specific volume for a detailed quote.
• Are the needles ready for sterilization?
  Our needles are manufactured in a controlled environment and can be finished with an electropolished surface. They are compatible with standard sterilization methods including autoclave, gamma radiation, and ethylene oxide.
• How do you ensure quality and consistency in large orders?
  Our automated etching process combined with rigorous in-line inspection and statistical process control ensures that every batch meets exact dimensional specifications and quality standards.
• Can you help with regulatory documentation?
  As a professional manufacturer, we can provide material test certificates, dimensional inspection reports, and process validation documentation to support your medical device regulatory submissions.
