What is the profession of mold?

Question 1: What is the specialty of mold? Mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts.

In industrial production, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping, stretching and other methods. In short, it mainly achieves the processing of the shape of the object through changes in the physical state of the molded material.

According to the different materials being formed, molds can be divided into metal molds and non-metal molds. Metal molds are further divided into: casting molds (non-ferrous metal die-casting, steel casting), and forging molds, etc.; non-metal molds are also divided into: plastic molds and inorganic non-metal molds. According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold, etc. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds, etc.

Main courses:

Question 2: What are the majors in molds? First of all, you need to position yourself which type of molds to learn, such as plastic molds, stamping molds, die-casting molds, automobile covering molds, etc. According to the types of these molds, there are Whether you are an ordinary employee or a mold apprentice in a factory of this type of mold, you can understand the structure and principles of the mold, and then collect books and information about this type of mold (there are many in online forums), study in detail, and learn from the masters. Of course, you can also choose to study based on the types of molds you currently have access to.

The suggestion is to learn on the job and apply what you have learned to get half the result with half the effort. While practicing, you should choose computer software according to the type of mold you have learned to lay the foundation for future design work. Plastic molds, die-casting molds, and automobile covering molds generally use UG, pro/e. Stamping molds generally use CAD. You also need to choose a 3D software, such as UG, pro/e, or SOLIDWORKS. Also, don’t think or believe that you can do mold design as long as you learn software well (there are many training courses that advertise mold design, but in fact they only train software. Software is only a small part of mold design. There were no computers before. When using software, the mold teacher still makes the mold through manual drawing).

Question 3: What is the major of mold manufacturing? It is a branch of mechanical manufacturing. It belongs to the category of tooling and fixtures. It is not taken seriously in state-owned heavy industries. In the coastal Yangtze River Delta, mold design and manufacturing refers to mastering mold design and manufacturing. Basic professional knowledge and strong practical work ability

Question 4: What major does mold manufacturing and design belong to? It belongs to mechanical engineering. This major has developed well in the machinery industry recently, because I am in this field. If you are working in the industry and will develop well in the future, it is recommended to learn automotive molds, which is better.

Question 5: What is the most important thing about the mold professional course? Based on the actual situation, here I would like to try to provide some suggestions for your reference.

1) Engineering drawing is the foundation of this major and an indispensable "language" for technical communication at work. As a mold designer, you must use the most concise view to accurately and clearly express the structure of each part. As a mold master, you must accurately understand every information conveyed in the drawings. The foundation must be laid firmly.

2) Computer-aided design and processing (CAD/CAM) is a tool for mold design and processing. Currently, the more popular CAD software in the industry include Pro-E, UG, Solidworks, AutoCAD, MasterCAM, etc. It is best to be proficient in one, and have a deeper understanding of the others.

3) Metal materials and heat treatment are very useful in practical work. It can give us insight into the various properties of mold materials and tell us why we choose this material over another. Of course, there may be some differences between the metal materials that can be learned in school and those actually used in the industry. But the things in the course are always basic.

4) Tolerance fitting and technical measurement must be learned well.

5) Plastic/stamping molding process and equipment. Mold engineers must have a deep understanding of both metal materials and engineering plastics. In addition, it is necessary to have an in-depth understanding of the molding process and its equipment.

6) Mold manufacturing process and equipment, if you don’t understand the process and equipment, talking about design will be like a castle in the air. Of course, the best way to learn this kind of professional course is to practice while learning. Professional mold manufacturing equipment includes Lathe, Drilling, Grinding, CNC, EDM, Wire-Cut, Jig-Grinding, etc.

7) Moldflow analysis (Moldflow).

8) Industry trends. Must understand before graduation.

9) Foreign language. With the continuous development of the industry, many companies are gradually going international, and many large companies themselves are multinational groups. If you are not proficient in a foreign language, especially English, it will be difficult for you to get ahead.

I wish you good luck in the Year of the Ox and good academic progress!

Question 6: What major should I study in college that is related to molds? There is no undergraduate program for mold design. This category is too small, so he agreed to call it the Department of Mechanical Engineering, which is usually offered by vocational colleges. Of course the good ones are, the mechanical majors at Tsinghua University, Huazhong University of Science and Technology, and Jiaotong University are all good. If you major in mold and die, you will learn the same things there. The key depends on your own understanding and future internships. There is also the application of 3D software.

Question 7: Employment prospects of the mold major. The mold major has good prospects. Although there are many people studying this field in recent years, the market is still short of talents. It is necessary to be better than others and learn well. This is a good iron rice bowl. You just have to be willing to endure hardships. I also study mold... Hehe, let’s talk together when we have time

Question 8: What certificates are required for the mold major? During the mold manufacturing, assembly and debugging process, the mold designer needs to participate in discussing partial or overall modification plans until the mold can produce qualified products and the mold acceptance is completed. 2. Mold simulation analysis: When designing molds, based on experience and general principles, the mold designer has one or several basic assumptions about the mold structure. Can such a mold successfully produce qualified products? In actual production, countless factories have encountered failures of varying forms and degrees. In serious cases, the mold cannot produce qualified products at all. Even if a lot of manpower and outsourcing costs are invested, or even new molds are redesigned and manufactured, qualified products still cannot be produced, and the project completely fails. When encountering a more difficult mold, CAE, an effective weapon, should be used to analyze and verify the various possibilities of the mold and find the most reasonable mold structure and process plan. This step is to optimize the mold and verify the mold design. For example, for stamping molds, we use Stamp Engineer to analyze (we have also used Pam-Stamp for a long time in the past), analyze and compare possible solution variants, and finally find the most reasonable mold design solution. The mold design scheme that has been optimized and verified in this way greatly improves the success rate. The mold debugging time is greatly shortened, which not only saves time, but also saves a lot of unnecessary mold trial and mold repair costs. 3. Mold CNC processing programming: Except for individual companies, general stamping mold designers only design molds and do not perform CNC programming. There are many examples of injection mold designers who also perform CNC programming while designing molds. In general, mold designers do not do CNC programming. The programming task is performed by CNC programmers who specialize in programming. Programmers analyze the tasks that require CNC machine tools for processing, write appropriate programs based on the factory's conditions, and hand them over to the processing workshop for use. Usually, the program is sent to a designated folder on the computer in the mold manufacturing workshop through the network. 4. Mold manufacturing and product technology: Various problems are often encountered during the mold manufacturing process and when using molds to manufacture products. This is especially true when starting a new process.

Selection of machine tools, selection of cutting tools, selection of cutting parameters, selection of coolant, tool feed speed, allowance, tool setting, how to position, how to detect, when to perform heat treatment, etc. are issues that often require process engineers in mold manufacturing. A matter of making up your mind. In terms of product technology, process engineers have more headaches. When choosing process parameters, we often focus on one thing but not the other, and cannot find a set of optimized parameter values. The method of simply fixing other parameters and changing only one parameter to find the optimal value loses its effect when 3 or 4 parameters (such as the injection molding process) are interdependent. After the first parameter finds the best value when it changes independently, when the second parameter changes independently and finds the best value, the previous best value of the first parameter is no longer effective and must be found again. There are also principles that can be followed for this kind of multi-parameter optimization, such as the Taguchi method. These are the weapons that a good process engineer often uses. 2. Mold designer level You can check the mold designer professional standards according to your own situation. The minimum is Level 3 (some places have Level 4, Shanghai has Level 3), and the highest is Level 1. Students who have just graduated basically correspond to level 4 or level 3. After training, they basically correspond to level 3. Level 2 and above require work experience. 3. Learning software The most popular software in the mold industry include AutoCAD, Pro/E, and UG. It cannot be denied that other software is also more common. However, there is no way to compare with these 3. (1) AutoCAD is a software that is relatively easy to learn and can be used as the basis of CAD. This is a software that almost everyone in the industrial field can master. This is a 2D software. There is no need to learn its so-called 3D functions because it is basically not used for 3D purposes. After learning this software, you can stay at this stage, or you can learn one of the following two 3D software. (2) Pro/E (the design function is stronger, but the programming function is relatively weak) (3) UG (the design function is not as good as Pro/E, but the programming function is relatively strong) You can learn either of these two 3D software. 4. Improvement If you want to improve your mold design capabilities, you may consider participating in a training. After training, you can get a truly corresponding position.

Question 9: Introduction to Mold Design and Manufacturing Major The mold design and manufacturing major mainly focuses on learning the design of plastic injection molds, stamping molds and die-casting molds, as well as mold fitter, lathe, and CNC milling. The basics are taught Subjects also need to learn the basics of mechanical drawing, materials, engineering mechanics, and mechanical design; the software involved includes CAD, PROE, MASTERCAM, UG, and CIRMATON

Question 10: Employment prospects of the mold major. According to Zhitong talent market statistics, The demand for mechanical and electronic talents by recruiting companies has always been high, and mold and mold positions are among the best. The personnel managers of many companies have shown great enthusiasm for mold design talents and CNC numerical control processing talents. Mold design talents who understand drawing software, can read drawings, can use AUTOCAD, PRO/E, etc. to draw mold drawings and processing drawings, have certain work experience, and understand processing technology, can use MASTERCAM or UG to write tool paths, and have certain CNC experience CNC processing talents are the most urgently needed talents in society at present. The future is bright for CNC mold technicians.
