There are many complete and huge automobile production bases in China. With the development of production technology, the production process is no longer mysterious. More efforts have been transferred from the customer's management and control of production quality to meet the demand of customers in the production process.
Let's talk about the advantages of complex plastic parts of automobiles
1. Plastic can be processed and molded at one time, with short processing time and guaranteed precision; under the condition of experiment permission and customer permission, it can be recycled for secondary molding, and the recycling of waste products is also very high.
2. Plastic products are light and have good elastic deformability. They can absorb a large amount of collision energy. Their buffering effect on strong impact is obviously better than other materials, which will play a better protective role for vehicles and passengers.
The front and rear bumpers of many cars are made of plastic materials to reduce the impact of external objects on the body. Plastic also has the function of absorbing and attenuating vibration and noise, which can improve the riding comfort. Many mold factories have already received bumper orders from Ford, GAC and even Land Rover, and their manufacturing technology is very mature.
3The plastic has strong corrosion resistance, local damage will not corrode. It is very difficult to find non plastic parts in the refrigeration system of automobile air conditioning.
4. The modified materials are made by adding different fillers, plasticizers, hardeners and elastomers to meet the use and requirements of different parts on the vehicle. As early as many years ago, the 18 business unit of BYD group has been able to transform the corresponding raw materials to fully meet its own product requirements. What's more convenient is that the color of plastic can be adjusted by color masterbatch and toner, which saves the trouble of painting. The electroplating performance of plastic is better than that of other materials.
How to achieve the technical requirements of customer requirements by means of management. As far as the production grass-roots units are concerned, it is impossible to achieve this kind of thing by means of management. I now use the complete process of a product to say my personal opinion
1, Project management of auto parts
1. Introduction of new products
The technology and management methods at this stage should be based on the explicit and implicit needs of customers. These requirements can be seen in the information of customers. The source of internal transmission is the project manager. The project manager can timely, effectively and accurately transfer the information and realize the information in the development process. This is the correct start of production.
Project introduction is not only a matter for project managers and project engineers, but also a case can be concluded only when effective logistics can be formed and recognized and paid back. So it takes a small core team and a lot of production resources to do it.
Let's briefly describe the basic project team members and responsibilities:
Project Manager (PM)
Receive, save, distribute and manage the customer's demand information; organize relevant personnel to review the customer's demand; communicate with customers in time for unclear or unclear customer information
Project Engineer (PE)
Ensure that customer requirements are effectively transformed into project development requirements, and timely communicated to relevant units to ensure that they are realized in the follow-up project development process
Quality Engineer
To review the quality aspects of customer requirements; to transform the customer's quality standards into internal quality requirements; to realize the customer's quality standards in the project development process, and to supervise and control them
The team of the new project is very small and simple. The biggest responsibility is to analyze the customer information and realize the explicit requirements in the data. Everyone hopes to have good results at the beginning of production, and any new product will produce good results only after detailed planning. So we say that the project is also technology, and how to play the technology is the sophistication of management means.
2. Technology in the process of the project
Many people think that this stage does not involve any technology, because they have ignored the key to the transformation of information into reality -- the realization of files. Many people think that files are just typing a few words in front of the computer. This idea just ignores that the basis of files comes from production reality, such as FMEA, APQP, etc
The main means of transforming information into production capacity is to control the process with the execution of various documents, so there is the so-called "five tools". The goal is to promote contact with everyone involved and ensure that the required steps are completed on time. It is impossible for one person or department to complete all the work, and it must be cross sectoral cooperation.
Make detailed planning in advance, identify the risks of human, machine, material, law, environment, measurement and other risks, and take corresponding measures. Even at the expense of short-term economic goals, we should try our best to ensure that the products are ready at one time. No matter how excellent the project manager is, it can only be completed by all departments with the assistance of professional technical personnel.
In the first stage of the project, from the establishment of the team to the establishment of the project, only a simple project manager can complete all the work. At this time, the main task is to receive and digest the information. After establishing a suitable team, the project manager needs to deliver the digested information to the relevant responsible engineers for classification and implementation.
