Company Profile

Shenzhen Xinhaisen Technology Limited is a professional manufacturer specializing in the precision etching of metal parts. We are dedicated to the production of high-precision metal parts, leveraging unparalleled speed and high-quality standards in raw material procurement and manufacturing.Our technology is widely applied across the Communications, Acoustics, Optics, Medical, Aerospace, Automotive, and Home Appliance sectors. While we are renowned for products such as speaker meshes, grilles, and filters, our precision etching process is also the ideal solution for manufacturing Beauty Microneedles. We handle various metal materials with thicknesses ranging from 0.02mm to 1.5mm , achieving industry-leading precision with micro-holes as small as 0.03mm and line widths down to 0.015mm.

We pride ourselves on high precision, fast turnaround times, and product variety, which has earned us a strong reputation among clients worldwide.

What is Etching?

Etching, also known as photochemical machining or metal photochemical etching, is a precision manufacturing process used to create complex metal components.

• Cleaning & Lamination: The metal coil is thoroughly cleaned and laminated with a light-sensitive photoresist on both sides.

• Exposure & Development: A photographic tool with the microneedle design is placed on the metal. UV light hardens the photoresist in the shape of the needles. The unexposed areas remain soft and are washed away during development, leaving the bare metal exposed.

• Etching: The metal is sprayed with an etchant solution that dissolves the exposed areas, forming the sharp, precise microneedle structures from the bottom up.

• Stripping: The hardened photoresist is stripped away, revealing the finished, burr-free microneedle array.

This process is perfect for microneedles because it creates burr-free, sharp points without mechanical stress or heat-affected zones, preserving the material's integrity.

Product Features

Our precision-etched Beauty Microneedles offer superior performance for modern skincare devices:

• Ultra-Sharp Precision: Achieves incredibly sharp tips for painless penetration of the skin's outer layer, enhancing the absorption of serums and active ingredients.

• Burr-Free & Clean: The chemical etching process ensures absolutely no burrs or mechanical stress on the metal, guaranteeing safety and comfort for the user.

• Consistent Array Pattern: High uniformity of needle height and spacing, ensuring controlled and even microneedling results across the treatment area.

• Material Versatility: Available in various biocompatible metals, including Stainless Steel (SUS304, SUS316L) and other medical-grade alloys.

• Customizable Geometry: We can produce various needle shapes, heights, and array densities to suit different derma roller, stamp, or pen applicator designs.

• Thin Material Expertise: Expertly processes thin materials to create fine needle structures.

Product Applications

Our etched microneedles are essential components in modern aesthetic and medical devices. They are used for:

• Derma Rollers & Derma Stamps: To create micro-injuries that stimulate collagen production and enhance topical product penetration.

• Microneedling Pens: As disposable or reusable needle cartridges for professional skincare treatments.

• Transdermal Delivery: In patch form for painless delivery of vaccines, insulin,or others.

• Cosmetic Patches: For dissolving or coated microneedle patches that deliver anti-wrinkle or brightening serums directly into the skin.

• Electroporation Devices: As conductive electrodes to enhance skin permeability.

Why Choose Xinhaisen Beauty Microneedles?

• High Precision: Our ability to etch features as small as 0.015mm ensures that every needle point is sharp and uniform, critical for effective and painless treatment.

• Unmatched Speed: Whether it is a prototype sample or a massive commercial order, our efficient production line ensures we meet tight deadlines.

• No Burrs, No Stress: Unlike stamping or laser cutting, our etching process guarantees perfectly smooth edges with no mechanical burrs or heat damage, ensuring medical-grade safety.

• Scalability for Large Orders: We are fully equipped to handle sudden, high-volume demands without compromising on the meticulous quality control.

• Cost-Effective Tooling: Compared to progressive die stamping, the tooling cost for etching is significantly lower, making it ideal for custom designs and iterative prototyping.

FAQ

Q: What materials can you use for microneedles?
A: We primarily use high-grade Stainless Steel such as SUS304 and SUS316L due to their strength, biocompatibility, and corrosion resistance. We can also discuss other materials based on your project requirements.

Q: How sharp can the needles be?
A: Our photochemical etching process can produce needle tips with a radius of less than 0.01mm. This level of sharpness allows for clean skin penetration with minimal discomfort.

Q: Do you offer custom shapes and sizes?
A: Yes, absolutely. Etching is a flexible process. We can create microneedle arrays in various shapes, heights, and patterns based on your CAD design or drawing.

Q: Is there a minimum order quantity (MOQ)?
A: We cater to both R&D and mass production. While we are capable of handling massive orders, we also welcome smaller, custom orders for prototyping and testing.

Q: Are the microneedles burr-free?
A: Yes. One of the main advantages of chemical etching over mechanical cutting is that it produces completely burr-free components. There are no secondary finishing processes required, and the product is safe for skin contact.

Q: What is the typical lead time?
A: Lead times vary depending on order complexity and volume. However, due to our efficient processes, we are known for our speed. Please contact us with your specific requirements for an accurate quote and delivery schedule.
