This digital display derma pen casing is a high-precision swiss machined solid 6061-T6 aluminum component specially designed for electric micro needling mesotherapy beauty devices. The integral pen shell blank is finished through sophisticated swiss machining process to form accurate ergonomic curved contours, tapered head and waist retraction structure. Secondary CNC milling process is adopted to complete irregular slots, digital display windows and key sinking platforms that cannot be achieved by single swiss machining.
As a professional custom CNC machining manufacturer, we support full OEM and custom service for all beauty pen hardware accessories. Multiple premium surface treatments are available, including mirror polishing, fine wire drawing, dual-color hard anodizing and sealing. All internal mounting holes, threaded structures, DC charging ports and component assembly cavities are precisely pre-machined to ensure perfect fitting of internal motors, batteries and circuit systems. Ideal for customizing handheld skincare and portable aesthetic device housings for beauty brand manufacturers.

We are a professional CNC custom manufacturer specializing in swiss machining and CNC milling custom parts, providing one-stop OEM custom service for beauty equipment aluminum housings. We fully support customized production according to customers’ technical CAD drawings or physical samples. All structural parameters can be customized, including overall dimensions, internal cavity layout, window size, hole position and thread specifications. We offer diversified custom surface finishes such as personalized polishing, wire drawing and multi-color anodizing. In addition, we provide custom logo engraving, small-batch prototype trial production and large-scale mass production services to meet different customer project demands.

1. Solve Assembly Tolerance Mismatch Points

   Adopting high-precision swiss machining and CNC composite processing, the product achieves ±0.02mm ultra-high tolerance accuracy, effectively avoiding loosening, jamming and poor fitting problems of internal electronic components during assembly.

2. Eliminate Poor Surface Durability Issues

   Standardized dual surface finishing and professional anodizing sealing treatment solve common points of ordinary casings such as easy scratching, fading and corrosion, greatly improving product service life and texture.

3. Avoid Multi-Procedure Processing Errors

   Integrated swiss machining and CNC milling one-stop manufacturing replaces separate processing, effectively reducing cumulative errors and ensuring consistent product batch stability.

4. Upgrade Product Ergonomic Experience

   Integrally swiss machined ergonomic contour without secondary splicing eliminates gaps and burrs, delivering smooth hand feel and high-end product appearance.

5. Accelerate Customer New Product Launch

   Flexible OEM custom service supports rapid prototype iteration and personalized structural adjustment, helping beauty equipment brands shorten R&D cycles and seize market opportunities.

We implement strict full-process quality control for all custom swiss machined aluminum derma pen housings. First, complete incoming material inspection is conducted to verify 6061-T6 aluminum material qualification and ensure raw material purity and performance. After swiss machining forming and CNC milling finishing, first article inspection and batch sampling dimensional testing are carried out with high-precision measuring instruments to guarantee tolerance compliance. Comprehensive appearance inspection is performed for polishing, wire drawing and anodizing surfaces to remove defective products. Thread matching and real assembly tests are implemented for each batch. Final full inspection before shipment ensures all OEM custom products meet international quality standards.
