Case Study: Metal Head Processing for High-End Skincare Brand Beauty Devices from Europe and America: Solving the "Compliance + Experience + Timeliness" Triple Pain Points through Precise Manufacturing

I. Client Background and Core Pain Points
The client is an upscale skincare brand. When launching its first home-use beauty device in 2025, the client encountered three major challenges in the processing of the metal head component, which hindered the product launch and user feedback:·Compliance Issues: The head needed to comply with EU REACH and US FDA biocompatibility certifications. The original partner used ordinary 304 stainless steel for processing and lacked material traceability, failing the entry review;

·Skin Sensitivity: The head needed to be "smooth, edge rounded, and have uniform heat conduction", but the original process could not meet the requirements for skin sensitivity details. User tests reported poor results;
·Long Delivery Cycle: Traditional processing required 6 steps and a 28-day cycle. The client needed to deliver 5,000 units within 18 days to support global pre-orders, resulting in high risk of delays.

II. Client's Selection Logic: Precise Matching of Capability and Demand
·Compliance Qualifications Coverage: Deeply specializing in the processing of skin-contact hardware components, the factory has an exclusive purchasing channel for medical-grade 316L stainless steel and has obtained ISO medical device quality management system certification, directly adapting to the European market entry standards;
· Skin Sensitivity Technology Guarantee: Equipped with 8 five-axis CNC finishing machines and 2 automated precision polishing lines, it can precisely control the surface accuracy and roundness of the head;
·Efficiency Capacity Adaptation: Independently integrating "rough processing → fine processing → surface treatment → finished product inspection", without external collaboration turnover, supporting small-batch rapid replenishment orders.

III. Targeted Solutions
1. Breakthrough Skin Sensitivity Experience: Precision Processing + Detail Polishing
Five-axis CNC Integrated Processing: Completing the processing of the head's spherical surface, edges, and rounded corners in one go, avoiding clamping errors, with the error in the contact area between the head and the skin less than 5%;
Automated Mirror Polishing: Through the "rough polishing → fine polishing → mirror polishing" three-level process, the surface roughness was reduced from Ra 0.1μm to Ra 0.05μm, meeting the skin sensitivity requirements.

2. Compression Delivery Cycle: Line Integration + Flexible Scheduling
Process Optimization: Establishing a continuous production line to eliminate the time for external collaboration;
Capacity Scheduling: Allocating 3 five-axis CNC dedicated machines to operate 24 hours a day, with the daily production capacity per machine increasing from 80 pieces to 120 pieces; Preparing medical-grade 316L raw materials in advance to eliminate procurement waiting time.

IV. Case Summary
In this case, the factory targeted the client's core pain points of "compliance, experience, and efficiency" with "medical-grade materials + precision processing + onestop process": Through compliant material selection and certification to break through the market entry requirements of Europe and the United States, with high-precision equipment to guarantee skin sensitivity experience, and through line integration and inventory preparation to shorten the delivery cycle, ultimately solving the processing problems and adapting to its high-end product positioning and launch requirements.
