In the production process of spring products, what specific measures has Hangzhou Chaotuo Electric Automation Co., Ltd. taken to ensure the stability and reliability of product quality?

In the production process of spring products, Hangzhou Chaotuo Electric Automation Co., Ltd. has taken a series of specific measures to ensure the stability and reliability of product quality. These measures cover all aspects from raw material procurement, production process control, quality inspection to finished product packaging, forming a complete quality management system. The following is a detailed description of these measures:

1. Raw material procurement and inspection
Selection of high-quality raw materials: The company is well aware of the decisive influence of raw material quality on the performance of spring products. Therefore, when purchasing raw materials, the company strictly screens suppliers to ensure that all raw materials come from certified high-quality suppliers. At the same time, the company will regularly review suppliers to ensure that they continue to provide high-quality raw materials.
Strict raw material inspection: After the raw materials enter the factory, the company will conduct strict inspections on each batch of raw materials. This includes material, wire diameter, appearance, and RoHS (Restriction of the Use of Certain Hazardous Substances) testing and other aspects. The company is equipped with advanced testing instruments, such as micrometers, EDX-1800 detectors, etc., to ensure the accuracy and reliability of the inspection results.
2. Production process control
Advanced production equipment: The company has more than 70 hardware production equipment of various types, including special equipment and production lines for spring production. These equipment are not only high-precision and high-efficiency, but also can meet the production needs of springs of different types and specifications.
Standardized operation process: To ensure the stability and controllability of the production process, the company has formulated detailed operation instructions and operating specifications. Employees must undergo rigorous training before taking up their posts to ensure that they can master the operating skills and comply with production specifications.
Process quality monitoring: During the production process, the company will conduct real-time quality monitoring of each process. This includes key links such as spring forming, heat treatment, and force testing. The company has also set up a special quality inspection department to be responsible for regular sampling and evaluation of the production process to ensure that the product quality meets customer requirements.
3. Quality inspection and testing
Force test: After the spring is produced, the company will conduct force tests on each spring. This includes compression force tests and tensile force tests. During the test, the company will use a professional load machine and set the test parameters according to the requirements of the engineering drawings and engineering approval samples. Through testing, it can be ensured that the force value of the spring meets the design requirements.
Finished product inspection: In addition to force testing, the company will also conduct a comprehensive inspection of the finished product. This includes wire diameter, outer diameter, free length, force, number of turns, rotation direction and appearance. The company is equipped with a variety of testing tools, such as micrometers, calipers, load machines, etc., to ensure the accuracy and comprehensiveness of the inspection results.
IV. Finished product packaging and delivery
Packaging requirements: Before the finished product is packaged, the company will check the packaging materials to ensure that they meet customer requirements and industry standards. At the same time, the company will also strictly control the packaging process to prevent the occurrence of undesirable phenomena such as mixing and deformation.
Identification and traceability: Each packaged spring product will be accompanied by detailed identification information, including product model, specifications, production date, batch number, etc. This information not only helps customers identify and use the product, but also can be traced when needed.
Delivery and after-sales: When delivering the product, the company will ensure the integrity and safety of the product. At the same time, the company will also provide comprehensive after-sales service, including the handling of product quality issues, technical consultation, etc.
