The main points of designing precision mold factory products

With the rapid development of electronics, telecommunications, medical, automotive and other industries, the precision and performance requirements of plastic parts are getting higher and higher. Precision injection molding requires plastic parts not only to have higher dimensional accuracy, lower warpage, And also have excellent optical properties. Injection molding is one of the most important plastic molding methods. How to improve the level of injection molding technology, produce high-precision plastic parts, and create high value-added products, mold design is an important link. In the design of precision injection molding molds, in addition to general mold design items, the following items should also be considered.

2 Proper mold dimensional accuracy

2.1 The relationship between the dimensional accuracy of the plastic part and the dimensional accuracy of the mold Consider the mold design, mold making and plastic part forming process according to the plastic part drawing. First, obtain the mold drawing size from the drawing size of the plastic part, then make the mold according to the drawing size of the mold to obtain the actual size of the mold, and then obtain the molded plastic part from the mold. But the problem is how to ensure that the actual size of the plastic part is within the dimensional tolerance required by the drawing.
