Precision injection molding technology of progress
Abstract:
The polymer precision injection molding technology, impact on precision injection molding of factors, including the precision molds, injection molding machine control accuracy, precision injection process control and puter control technology. These factors were discussed, and give the relevant solutions, finally introduces some advanced molding technology.
Key words:
precision injection; injection molding machine precision injection technology; Precision Injection Mold
In recent years, as electronics, munications, medical, automotive, and other industries of the rapid development of the high-precision plastic products, and high-performance requirements of growing precision molding technology to continue to progress, new technologies continue to emerge. Precision injection molding products not only require high dimensional accuracy, and low warpage, to write good, but there should also be excellent optical properties. Injection molding is the most important one of the plastic molding methods, including plastics plastics, injection, packing, cooling, and some of the basic process, thus affecting the precision injection molding of many factors.
1 precision molds
To produce sophisticated products, precision molds is essential. Die Die in general, the accuracy of the temperature control, mold and die design precision manufacturing, use of plastic shrinkage rate impacts.
Precision Mold temperature control
In general precision injection molding of parts, control mold temperature is to increase productivity. However mold temperature control for precision injection molding of great impact, it affects parts of the contraction, shape, crystallization, such as stress, hot and cold circuit design mold temperature distribution at the request reasonable, precise control accuracy, a die temperature of t
