As a qualified structural engineer, you need to know the following knowledge:

Proficient in a three-dimensional software and a plane CAD software; Mold knowledge (plastic mold and metal mold); Understand the material characteristics; Knowledge of surface technology; Mechanical knowledge and mechanical drawing; Production and assembly technology; Knowledge of quality and safety regulations.

First of all, software familiarity

Familiar with 3D design software (pro/E, UG, solidworks, etc.). ) directly determines the speed at which you make a product. For example, some people make a product for half a month, and some people make the same product for only one to four to five days, although it is not absolutely related to the proficiency of software use.

The use of old software still occupies a large share, so in addition to the use of software, there is another key point that it is also closely related to your familiarity with the product structure.

Second, the mold structure

The degree of understanding of the mold structure determines the difficulty of manufacturing the products you design. In severe cases, it may be impossible to mold or it may be a very complicated mold structure. For example, a structure that can be inserted without affecting the appearance will not be made into a row structure, and the required product functions will be realized with the simplest mold structure.

Third, understand the properties of materials.

Your understanding of the properties of plastics determines the reasonable degree of materials (including plasticity, hardness, transparency, high temperature resistance, fire prevention, ultrasonic wave, etc.). When you design a product. If you don't understand this aspect, the products you design may misuse expensive materials, or the strength of the products is not enough, and there are some other problems. Therefore, when designing the structure, you should consider the price of plastic on the premise of meeting the demand of the product, because the material cost of the product is directly related to the price of the product.
