Precision earphone shell accessories

Our Manufacturing Strength & Core Equipment

We boast a modern production base equipped with more than 30 high-speed and high-precision CNC machining centers and 2 advanced 5-axis CNC milling centers, covering a wide range of machining platform sizes to accommodate diverse earphone shell specifications. Beyond 5-axis CNC machining, our comprehensive production processes include 3-axis CNC milling, turning, grinding, polishing, anodizing, and injection molding (for plastic components), enabling us to realize one-stop service from raw material processing to finished product assembly, greatly improving production efficiency and product consistency.

Precision Earphone Shell Accessories: Advantages, Application Scenarios & Customer Cases

Our 5-axis CNC machined earphone shell accessories are designed for ultra-precision, excellent surface finish, and perfect structural fit. The 5-axis CNC machining technology allows for complex contour processing (such as curved earphone shells, hollow structures) in a single clamping, minimizing cumulative errors and ensuring consistent precision across large-batch production. These accessories are widely applied in the consumer electronics industry, including high-end wired earphones, wireless Bluetooth earphones, gaming earphones, professional monitoring earphones, and smart wearable audio devices, providing reliable structural support and aesthetic value for audio products.

Typical Customer Cases

Case 1: European High-End Wireless Earphone Brand - We collaborated with a well-known European audio brand specializing in high-end TWS earphones. The client required earphone shells with a curved ergonomic design, ultra-high precision (±0.003mm) for component fitting, and a matte anodized surface. Leveraging our 5-axis CNC machining centers, we completed the customized production of 200,000 sets of earphone shells within 25 working days. The product qualification rate reached 99.9%, and the client's product received positive market feedback for its perfect fit and premium appearance. We have maintained long-term cooperative relations, providing annual supply support of 500,000+ sets.

Case 2: Japanese Gaming Earphone Manufacturer - For a Japanese gaming equipment manufacturer, we produced aluminum alloy earphone shells and microphone mounts for their professional gaming earphones. The key requirements included high strength (using 7075 aluminum alloy), wear-resistant surface treatment, and precise dimensional control for waterproof assembly. Our professional technical team optimized the machining process, reducing the production cycle by 15% compared to the client's previous supplier. The products passed the client's strict waterproof and durability tests, and we successfully entered their global supply chain, supporting the production of their flagship gaming earphone series.

Visualized Production Process

We adhere to a strict and transparent production process to ensure product quality and on-time delivery. Each precision earphone shell undergoes the following standardized procedures:

• Raw Material Selection & Inspection: Sourcing high-quality metal (aluminum, stainless steel, titanium alloy) and plastic (ABS, PC) materials from certified suppliers. Conducting strict incoming inspections (chemical composition analysis, hardness testing, surface defect detection) to ensure raw material qualification.

• Design Optimization & Programming: Our professional engineering team optimizes client drawings (or provides custom design services) and compiles precise CNC machining programs, optimizing cutting paths to improve machining efficiency and surface quality.

• 5-Axis CNC Machining: Utilizing 5-axis CNC machining centers to perform high-precision cutting of earphone shell blanks, realizing complex shape processing in one step without repeated clamping.

• Secondary Processing: Conducting grinding, deburring, and polishing processes to refine the product surface and edges, ensuring a smooth touch and consistent dimensions.

• Surface Treatment: Implementing customized surface treatment processes according to client requirements to enhance corrosion resistance, wear resistance, and aesthetic appeal.

• Strict Quality Inspection: Using high-precision testing equipment (Coordinate Measuring Machine, CMM; Optical Measuring Instrument) to conduct full-dimensional inspection of products. Sampling inspection for batch products to ensure compliance with drawings and quality standards.

• Packaging & Shipping: Adopting anti-scratch, anti-collision packaging materials to protect products during transportation. Cooperating with professional logistics partners to provide global shipping services.
