Understand various indicators in cable production

Mechanical work comes into contact with many indicators every day, especially in the production of cables, which require rigorous quality control at all levels to deliver high-quality products to consumers. Therefore, the requirements for indicators will naturally be higher. At the same time, consumers can also learn relevant information through these indicators. Below, let's take a look at several production indicators that are closely related to consumers~
1. Scrap rate
Definition: This percentage is obtained by dividing the cost of waste materials by the total production cost or by dividing the total amount of waste generated by the total amount of products.
Purpose: Used as a result measure to determine whether the production process is being carried out in accordance with standardization.
2. Rework rate
Definition: Refers to the proportion of time spent on rework, obtained by dividing the rework hours by the production labor hours or the total number of reworked (repaired) products by the total production quantity.
Purpose: Used for measuring results, it can improve workstations with operational issues.
3. Product inbound inspection pass rate
Definition: This indicator is obtained by dividing the qualified quantity of product incoming inspection by the total quantity of incoming inspection.
Purpose: It can be used to measure the quality level of the entire production process.
4. Number of non-conforming products (or product defect rate)
Definition: The ratio of the number of customer returns/rejections or non-conforming products per million products to the total number of partial shipments or total production.
Purpose: To be used as a result measure to comprehensively display the impact of product dissatisfaction, enabling focused efforts to solve problems.
5. Customer inspection pass rate once
Definition: Refers to the quantity of products delivered, divided by the total quantity of products delivered, which are accepted after passing the customer's inspection.
Purpose: To be used as a result measurement to assess the quality level of finished products being shipped out.
6. Batch non conformance rate
Definition: Refers to the proportion of batches that need to be reworked (repaired or scrapped) due to unqualified inspection judgments among all inspection batches within a certain period of time, compared to the total number of inspection batches.
Purpose: To be used as a result measure to monitor the overall quality level of the process.
Production batch: refers to a certain quantity of products that are put into production according to the production plan.
What is directly related to consumers is the batch failure rate, which is most commonly used in the inspection reports of State Grid. The batch failure rate is used, and consumers can judge whether it is produced in the same batch as the unqualified products based on the batch information on the product. In addition, they can also judge the process and equipment situation based on other indicators provided by major wire and cable manufacturers before making a purchase.
