How to improve quality and improve yield rate

1. Improve production quality

As we all know, "quality is the life of an enterprise." Only with first-class quality can there be a broad market. How companies can improve product quality will be an eternal topic for every company.

First of all, raw materials must be checked to strictly prevent defective products from entering the warehouse and entering the production line. So how can we handle this first hurdle? (Responsible department: procurement, quality control)

Purchasing personnel need to select qualified suppliers to ensure that the quality of purchased materials meets the requirements. Quality control personnel assist procurement and urge suppliers to improve quality. After the materials arrive, quality control must be strictly controlled. Only qualified products can be put into storage.

Second level: Storage of materials (responsible department: warehousing department)

Storage of materials is also very important in quality management. Improper handling and storage may cause defective materials. has happened. All warehouse management personnel must follow the principle of focusing on the bottom and taking care of the top, and pay attention to handling and handling. You also need to do some "dust-proof, moisture-proof, sun-proof, rust-proof, etc." work. Check materials from time to time. Ensure the quality of material storage.

Third level: Manufacturing and production (Responsible department: Manufacturing and production department)

After materials enter the production line, they must first avoid poor material operation due to improper operation or use. Self-inspection, mutual inspection and random inspection are required for each work section and each other. Finished products need to be inspected by quality control, and only qualified products can be put into storage and sold.

Level 4: Product Transportation (Responsible Department: Logistics)

Why is product transportation also included in quality management? Improper transportation can also cause damage to the product. Therefore, the logistics department must choose a qualified and reputable logistics company for transportation.

(In addition, some companies also put after-sales service within the scope of quality management).

In fact, as long as the departments within the company perform their duties, supervise each other, and everyone participates in quality management, I believe that the quality of the products will be greatly improved, and the company will prosper

II ·Improving production efficiency

For enterprises, committing to improving productivity can reduce costs, withstand the pressure of price competition, and thereby gain more market share. If prices remain unchanged, an increase in corporate productivity means an increase in profits. Only with higher productivity can enterprises be truly competitive and avoid being replaced by foreign competitors. The productivity of domestic printing and packaging companies is relatively low. They should focus on improving productivity and not invest all their attention and funds in the market. Production is the foundation of business. If there is no guarantee of higher productivity, a larger market share does not mean higher profits, which is not conducive to the long-term development of the enterprise. Productivity is generally used to reflect the relationship between output and input in the production process. It is only a relative measurement index. General productivity is often expressed by the following formula: Productivity = total amount of products and services produced/total amount of resources consumed.

To consider the influence of multiple factors, total factor productivity (TFP model) must be used to calculate productivity: Total factor productivity (TFP): (sales revenue + inventory change + increase in the original value of the enterprise and equipment Value)/[(Return on assets in the base period) Get a valid TFP value. Since all productivity calculations have flaws, the TFP model also has shortcomings and must be used with caution in practical applications. In the TFP model, if inventory increases rapidly, the TFP value will increase accordingly, but the company may be facing the problem of product backlog. At this time, just looking at the TFP value can easily lead to misunderstanding. Productivity is of great significance to any business organization. For profit-oriented enterprises, the improvement of productivity means that the effective utilization of resources can be improved. A decrease in productivity means that there is a problem in production. The operations department can determine the cause of the decrease in productivity by examining the factors that affect productivity, and make corresponding improvements to improve productivity. There are many factors that affect productivity, generally including capital, methods, technology, quality, employee performance, and corporate culture.

Among them, the main reason why capital investment affects productivity is the investment in equipment and the utilization of equipment. Technical factors mainly refer to the application of technology. Only when technology is fully applied can the advantages of technology be brought into play. Employee work performance mainly refers to employees' work ability and work motivation. Corporate culture affects an organization's productivity all the time.

Other factors that affect productivity include:

1. The working environment includes materials, operation planning and design, machinery and equipment, lighting, temperature and humidity, environmental color, etc.

2. The higher the degree of standardization of the process flow, the higher the quality of the product and the higher the productivity.

3. Quality Differences Quality differences create distortions in productivity comparisons.

4. Scrap rate The scrap rate indicates the effectiveness of resource utilization. Obviously, an excessively high scrap rate means a waste of resources. Rework of product can also impact productivity.

5. Employee mobility Frequent employee turnover is not conducive to cultivating employee loyalty and cohesion to the company. Newly recruited employees must go through a period of time to adapt to the needs of the company. Moreover, the flow of employees may also cause the leakage of technology and business conditions, which is not conducive to maintaining and improving the productivity of the enterprise.

6. The employee incentive system directly affects productivity.

7. Training of employees Employee training is an effective way to continuously improve productivity.

8. Equipment Failure In the manufacturing industry, if equipment failure cannot be repaired in time, productivity will be seriously affected.

9． Application of the Internet The application of the Internet can reduce costs and improve productivity. The above are just common factors that affect productivity. There are many more factors related to specific industries. There are many ways for enterprises to improve productivity, but they must grasp key factors to improve productivity based on the specific conditions of the industry and the enterprise.

1. Investing in the most appropriate equipment and technology can effectively improve productivity. New equipment and technology are one of the most effective ways to increase productivity. A large U.S. insurance company invests 10% to 15% in improving its information technology and can achieve an annual productivity increase of 5%. For example, when a flexible packaging printing factory adopts Zhongshan Songde's shaftless gravure printing machine, the production speed can be increased to 350m/min, which is 75% faster than the 200m/min of a general gravure printing machine, significantly improving productivity.

2. Eliminate bottlenecks The production system is a whole, and the overall productivity is often determined by the bottleneck productivity. Increasing the productivity of any non-bottleneck cannot improve the overall productivity of the system. Only increasing the productivity of the bottleneck can improve the overall productivity. A system is most efficient only when the output rate of a bottleneck is equal to the sum of the output rates of all inputs to it.

3. Quality Control The key to quality control is to implement source quality control, which requires that the work must be done right the first time. If an error occurs, the production of the process must be stopped immediately. Front-line employees are not only producers, but also play the role of quality supervisors. Since employees only pay attention to this part, it is easy to find quality problems, which is conducive to improving the quality. When a printing and packaging company produces packaging boxes, if the printing quality is not up to standard and the front-line employees do not pull out the unqualified sheets in time, it is very difficult to inspect the printed sheets and they may not be able to detect them. After delivery, it is detected when the customer uses it, which affects the relationship between the company and the customer and causes large economic losses.

4． Adopting JIT production JIT (Just-in-Time) production is a combination of a series of production activities. Its purpose is to achieve mass production of raw materials, work-in-progress, and finished products while keeping inventory to a minimum. In this process, the parts arrive at the next process on time, are quickly processed in this process, and then transferred to the next process. The concept of JIT production is: only produce when needed and never overproduce. Anything above the minimum required quantity is waste.

5. The work of design employees is relatively monotonous because the work on the production line is relatively boring, and employees are generally not very motivated to produce, especially in assembly line work. Even when wages are higher, higher productivity cannot be guaranteed. Methods such as job enlargement, job deepening, job rotation and team production can be used to increase employees' production enthusiasm and improve productivity.

6. Improve work methods Increase productivity by increasing the throughput of an operation or group of operations, reducing costs and improving quality. Employees have a habitual movement pattern when using machines, tools, materials and work methods, which directly affects productivity. All employee actions must be reanalyzed, unnecessary actions removed, and erroneous actions corrected. When necessary, adopt new and more efficient action modes to greatly improve production efficiency.

7. Employee training: Increase employee training, change employees' misunderstandings, reduce the probability of making mistakes, improve employees' awareness and technical capabilities, and effectively improve productivity. Employee training costs are relatively low, but it can increase productivity by about 6% every year.

8. Motivating employees Companies can use team-oriented incentive compensation mechanisms to effectively increase productivity. This mechanism emphasizes team work, through careful evaluation, and rewards according to the individual contributions of individuals in the team to the team goals. Managers must clearly encourage productivity improvements and provide incentives to employees who contribute, including financial incentives and non-financial incentives.

9． Manage employees' daily work Enterprises must manage daily production, arrange production reasonably, reduce time waste, improve the effective utilization of working time, reduce equipment failure time, reduce idle assets, and maximize the efficiency of employees and capital.

10. Corporate Culture Advocate the concept of improving productivity in the corporate culture, so that all employees can form a strong awareness that improving productivity is an outstanding employee, and work together to form an environment for improving productivity. Improving productivity is of great significance to printing and packaging companies whose profits are shrinking. For the same product, whoever has the lowest price will have a competitive advantage and can win orders. In price competition, productivity is its basis. It can be said that whoever improves productivity will have the ultimate advantage in price competition.
