How can a novice design a complete set of plastic molds from scratch? I've talked about it here

The term DFM! Many students may not understand what it means. For mold designers or product designers, of course, they must understand and be proficient. Is this really difficult? In fact, this name may be called differently in each place; it is estimated that it is called DFM in East China and Central China. In South China, some of them are called Dahe. Therefore, no matter how it is called, everyone is relatively understandable and can Communication is OK.

In fact, this function is mainly for the exchange of information with customers. The information is classified as shown in the figure below;

How can a novice design a complete set of plastic molds from scratch?  I've talked about it here

This is the prototype of the product

The above information is what you must accurately understand and master before the mold designer receives the customer’s product and starts designing. If you don’t get the information first, you can design directly, then cut the material and send it to the workshop for processing. Then the trouble is a bit big, you may have to pay for it yourself!

After the demolding analysis of the product, as long as the mold-opening conditions are available, a mold-opening plan is required. Even if the mold-opening conditions are not available, a product modification proposal must be made to prepare for the customer's confirmation and design for us. The strength of the teacher is recognized, so the designer must not think that the customer’s things cannot be changed, and can only be done according to it! In fact, many product designers of customers are some top dishes, because they have not made molds at all, and they are very laymen in the manufacturing and processing technology or molding process of molds. Therefore, what about the products they make? So there may be no problem at all. Whether it is product structure, product assembly, plastic part appearance, or buckle and related functions, there may be major structural or functional problems. Therefore, at this time, Our designers, as mold experts, need to show our strength to customers. We must be guided and suggested thinking, from the customer’s point of view, and make feasible modification proposals for unreasonable places. Of course, the customer accepts If you don't accept it, then we don't care.

first of all! First determine the tolerance of the customer's product, whether we can meet it! And also make a tolerance pre-adjustment plan for the customer to determine. As shown below;

Tolerance is a very important part. Designers must pay attention to the details of each position, especially to distinguish clearly which are the tolerances for adding glue and which are the tolerances for reducing glue. After the tolerances are completed, they must confirm the way and the way of plastic products. Position and mold ranking method. As shown below;

After all the above is completed, start to perform a simple parting of the mold to determine the appearance of the product, the clamping line, the mosaic position, the core pulling method and structure, etc., as shown in the following figure;

Through the display of so many details, each step has a process, and each step requires software skills, mold technology, experience and cooperation in processing technology to complete the DFM mold design pre-analysis link. The designer can only go out if he knows this. , The salary is also more than 10K a month, so if you learn mold designers, you must first know your own learning method, learning process, and whether the courses you learn are all the designer processes that professional factories really need. There are many people After learning, I found that it is still zero foundation, which may be more messy than I did not learn. I don't know how to really use the technology I have learned to make money or make a fortune! Come on! classmates,
