Contents And Methods Of Wire And Cable Inspection

Wire and cable inspection implements the policy of combining "checking" and "prevention first".

The content of wire and cable product quality inspection is not only limited to product quality inspection, but also includes quality inspection of various factors that affect product production quality in each production link during the entire production process from raw materials entering the factory to finished products leaving the factory. Therefore, product quality inspection The scope and content are relatively wide. Specifically, the content of wire and cable product quality inspection can include the following aspects:

1. Quality inspection of raw materials, auxiliary materials, purchased and product-related parts and components used in the manufacture of wires and cables;

2. Inspection of machinery and equipment for the manufacture of wires and cables;

3. Inspection of fixtures, molds and process equipment used in the manufacture of wires and cables;

4. Supervision and inspection of the process structure cards of each process in the manufacture of wires and cables;

5. Inspection of various formulas used in the manufacture of wires and cables;

6. Factory inspection of wires and cables after completion;

7. Inspection of the production environment for manufacturing wires and cables;

8. Inspection of measuring tools, weighing instruments and instruments used in the manufacture of wires and cables.

There are various inspection methods for wire and cable products. According to the different inspection methods and functions, they can be divided into the following categories:
