Chinese watch manufacturers are the OEM industry base for global brand watches, and Shenzhen is the largest watch production city in China. What is the production process of Chinese watch manufacturers?

1. Standardized production process of watch customization for Chinese watch manufacturers

In the early stage of watch customization, the customer needs to determine the style he wants, etc., and the watch factory needs to determine all aspects before production. One is to smooth subsequent production, and the other is to save time and cost. Determine all the parameters before production, give the customer a transparent quotation, and after paying a certain deposit, start the formal production, from material procurement to QC, parts production, pre-shipment to customer confirmation, follow-up, etc. After the assembly of the bulk goods is completed, pay the remaining balance after the inspection, and then you can pick up the goods or deliver them to your home.

2. Standardized watch dial production process of Chinese watch manufacturers

The degree of rigor required in the production process of the dial is quite high. A finished dial requires the cooperation of several factories to complete, from the embryo factory, copper plate (or special material), abrasive factory (logo mold and letter nail mold), paint, UP factory, luminous, packaging, etc. Still taking Elsie watch manufacturer as an example, it is divided into five processes;

The first step of hardware processing: first cut the material, open the mold for stamping, press the shape, and then punch, the middle hole, the letter hole, and the logo hole. Hood corners.

The second step of shading treatment: perform texture treatment on the polished copper plate, and perform different shading effects according to different processes of the literal. Commonly used shading processes include sweeping and sandblasting.

The third step of electroplating: is the process of coloring the copper sheet. Before electroplating, the copper sheet is cleaned with ultrasonic equipment, and different colors are electroplated according to the literal color of the cost.

The third step of oil injection: oil injection is generally a process of oil injection if there are special requirements or the color of the electroplating cannot be met, and the dark color is mostly.

The fourth step is silk screen and pad printing: silk screen and pad printing are both ways of printing scales or logos.
The fifth step is qc+packaging: all process inspections are ok, and the package is shipped.

3. Standardized watch case prototype processing process of Chinese watch manufacturers

(1) Programming: Write the program to control the processing machine according to the 3D drawing provided by the customer.

(2) CNC processing: According to the written program, the knife is run on the aluminum alloy material to obtain the prototype of the watch case.

(3) Manual grinding: the surface of the hand plate just out of the machine will have a lot of knife marks, ridges, etc., which need to be polished smooth with sandpaper.

(4) Quality inspection: After the watch shell prototype passes the inspection of the QC department and there is no problem, it can go to the next assembly process.

4. Standardized watch assembly process requirements for Chinese watch manufacturers

(1) The original power part of the watch spring that drives the entire movement to run continuously needs to be made of stainless, not easy-to-break, high-strength, and high-elastic materials;

(2) The assembly of the watch is very strict, and it is carried out in the 100,000-class clean, dust-free constant temperature workshop with air-conditioning equipment invested by the Elsie watch manufacturer. After the assembly of a watch is completed, it will go through a comprehensive verification for more than ten days, after simulation, actual running seconds, amplitude measurement, electronic meter test, appearance, and other assessments.

(3) The tolerance of watch parts is only allowed to be 0.005 mm. After passing the inspection with forty microscopes, it is riveted with the balance wheel.

(4) There are strict requirements on the performance, surface condition, and dimensional accuracy of the raw materials of the watch. For example, the material for making the hairspring requires high strength, and anti-magnetic properties, and is less affected by temperature changes. It can only be made of a special stainless and constant elastic alloy material.
