Watch Connector Parts

Core advantage

Xincheng is a professional CNC machining factory and also a manufacturer and supplier of processed parts in China. Watch Connector Parts customization is the extreme requirement of the watch industry for the miniaturization, high precision and stability of parts. As a key component for transmitting power and connecting components in the watch movement 苾, the dimensional accuracy and assembly compatibility of the connector first determine the timekeeping accuracy and service life. The Watch Connector Parts feature "small size, high precision requirements, and sensitive material properties". Our customization service precisely matches the demands through three core advantages:

Precision forming of micro-structures: For common micro-structures such as pinholes, clamps, and thin arms in watch connectors, a combined process of precision milling and electrical discharge machining is adopted. The minimum processing size can reach 0.1mm, and the key dimensional error is controlled within ±0.002mm. It perfectly reproduces the details of the drawing and solves the problems of "processing deformation" and "dimensional deviation" of micro-parts.

Material and working condition compatibility: Customized material solutions are provided based on the functional requirements of the connector (conductivity, wear resistance, and lightweight). For instance, brass material ensures electrical conductivity, stainless steel enhances durability, and titanium alloy achieves lightweight. All materials undergo anti-corrosion treatment, making them suitable for scenarios where watches are worn for a long time and come into contact with moisture and sweat. The assembly structure such as the gap ensures that the assembly tolerance with components like gears and dials is less than 0.005mm, reducing the subsequent adjustment time of the movement.

Assembly compatibility optimization: Based on the movement assembly drawings provided by the customer, optimize the chamfering of the connectors and enhance the assembly efficiency.

Watch Connector Parts customization process

1. Demand Matching and solution design (response within 24 hours): You provide 2D/3D drawings of the connector and assembly requirements for the movement. A dedicated engineer for the watch industry will communicate with you one-on-one about the functional requirements (conductivity, fixation, transmission), and provide material selection, process route and quotation plan.

2. Prototype Prototyping and Confirmation (3-5 working days): 1-3 prototype samples will be produced using rapid prototyping technology. After full-size inspection by a 2D image measuring instrument, the samples will be sent. We will assist you in completing assembly tests and optimize process parameters based on feedback.

3. Precision mass production and full inspection (5-10 working days): Mass production is carried out using automated micro-processing equipment. Each product is fully scanned by a CCD vision inspection system, and key dimensions are calibrated with a three-coordinate measuring instrument to ensure consistent batch accuracy.

4. Finished product delivery and Traceability: Material certificates and precision inspection reports are provided along with the goods. A unique number is laser-engraved for quality traceability. On-site technical guidance for assembly is supported.
