Injection molding engineering is a complex project, which involves injection molding raw materials, injection molding machinery and peripheral equipment, injection molds, product quality, injection molding materials and product performance testing, etc. Therefore, it requires injection molding engineers to have a wealth of professional theoretical knowledge And skills in order to be competent for the job.
As an injection molding engineer, you should master the following professional theoretical knowledge and skills:
1. Knowledge of mechanical drawing
Can understand product drawings, can check product size and appearance against drawing requirements, and can use CAD, UG, PRO-E and other drawing software proficiently.
2. Have a very rich knowledge of raw materials
Familiar with the physical and mechanical properties, chemical properties, electrical properties, thermal properties, processing methods and processing characteristics of various injection molding materials. You should be familiar with the various injection molding materials used in the production of the company, and you can also have a preliminary understanding of the injection molding materials that have not been used by the company for the time being. Be able to understand the raw material property table, understand the meaning of the values ??in the property table and the corresponding test methods, and be able to make simple comparisons of different properties and different grades of raw materials.
3. Familiar with the composition, structure principle and operation method of injection molding machinery and peripheral equipment
Understand the meaning of the technical parameters of the injection molding machine and peripheral equipment, and be able to select the injection molding machine and peripheral equipment according to the technical parameters. It should be very clear about the key structural parts (such as the clamping system of the injection molding machine, the injection molding system, the operating system) and the key components (such as the oil cylinder, machine hinge, screw, barrel, etc.).
As an injection molding engineer, it is not enough to be familiar with the structure and use characteristics of various types of injection molding machines, but also to be able to manipulate and use them proficiently. This is an essential basic skill for every injection molding engineer. An injection molding engineer who does not know how to adjust injection molding machines is just a theorist, and it is impossible to master the essence of the injection molding process.
As an injection molding engineer, you must also understand the meaning of the technical parameters of the injection molding equipment. According to the technical parameters of the injection molding equipment, compare and judge different manufacturers and different types of injection molding equipment, and assist the enterprise in the selection and purchase of injection molding equipment. It is not only the responsibility of an injection molding engineer, but also the professional knowledge and abilities that an injection molding engineer should possess.
4. Familiar with the structure of the injection mold and the working principle of each part, familiar with the correct use of the mold
And maintenance methods, the structure design of injection products and the knowledge of mold design should also have a certain understanding. As an injection molding engineer, it is necessary to understand the knowledge of injection product design and mold design, because many product defects in injection molding production are caused by the unreasonable product design or mold design. If the injection molding engineer does not have this The knowledge and experience in this field cannot analyze the causes of defects, and cannot make reasonable suggestions. The problem cannot be solved by blindly trying to improve through the adjustment of the injection molding process.
As an injection molding engineer, you should be familiar with the structure of the mold and the use and maintenance methods, so that it is possible to use it correctly in production, and the injection foreman or technician should give guidance. And a mature injection engineer, his understanding of the mold gating system, the knowledge and experience of the injection method, the size of the runner, the size, quantity and location of the gate, and the setting of the cold well are more than that of the mold. Designer's.
5. Possess rich theoretical knowledge and practical experience of injection molding process
Understand the molecular structure, chemical, physical and mechanical properties and processing characteristics of injection molding materials, understand the principle of polymer processing, understand the impact and interaction of the five process parameters of temperature, pressure, speed, time, and position on the injection molding process, and be able to correct according to the injection molding practice. Judge the process factors that lead to injection defects and improve them.
6. Familiar with various quality defects of injection products, their causes and solutions.
Compared with quality engineers, injection molding engineers must not only be familiar with the various quality defects of the product, but also must know the reasons for the defects and find solutions. The work of quality engineers focuses on the discovery and control of quality problems.
7. Familiar with injection molding raw materials and product performance testing methods
Be proficient in using relevant test tools, test instruments or equipment. As an injection molding engineer, being able to skillfully use vernier calipers, micrometers, analytical balances, plug gauges, etc. are all basic skills that must be mastered. And for some important experiments and testing equipment, testing equipment should be able to operate and use. Such as plastic tensile, compression, bending, impact, hot melt index, combustion, hardness, wear resistance, adhesion and other classic tests, not only must be familiar with the test method, but also be able to operate the test instrument, if necessary, you need to do it yourself Experiment to obtain more accurate test data.
8. Have strong learning ability and adaptability, and can continuously sum up experience, form written process documents for production guidance.
People who are not born with knowledge, can there be no confusion? The same is true for injection molding engineers, and there will be some things they don’t understand, when they have relevant experience. However, as an injection molding engineer, you must have strong learning and adaptability, and must master the correct learning and working methods in order to master relevant knowledge and skills in a short period of time to provide guidance and support for production. Of course, this is also the quality that any engineer should possess.
9. Other knowledge and skills.
As an injection molding engineer, you must have strong professional knowledge and rich practical experience to solve injection molding problems that occur in production, but also have a certain degree of management ability to assist injection molding supervisors or managers, and to injection molding technicians and foremen And employees for technical management. Of course, nowadays companies are facing the world, and good foreign language skills will surely make injection molding engineers' communication skills and work abilities even better.
Due to the complexity of injection molding engineering, injection molding engineers must have good professional theoretical knowledge and rich practical experience to be competent. Modern enterprises need cross-type talents who understand both technology and management. Only managers who understand technology and understand the objective laws of the business they are engaged in can they follow the objective laws of the development of things to manage, avoid detours, and manage better. .
