Development of injection molding technology for plastic products

In recent years, with the increasing use of plastic products, in order to continuously meet the requirements for the development of highly integrated, highly precise, high-yield injection products, and to achieve the aggregate state, phase morphology, and organizational morphology of product materials, etc. In terms of control, to achieve the composite of heterogeneous materials on the product, to maximize the characteristics of the polymer, to achieve the purpose of high performance of the product, injection molding technology has been greatly developed.

In terms of injection molding technology, gas-assisted injection molding, structural foam molding, reaction injection molding, co-injection molding, push-pull molding, injection-compression molding, low-pressure injection molding, alternating injection molding, melt core injection molding, and dynamic packing Key technologies such as in-mold reaction, foaming, vibration, and gas assist are introduced in injection molding, which greatly enriches the content of traditional injection molding processes, so that the flow characteristics of plastics, mechanical properties of products, and appearance quality are all effectively controlled.

In terms of injection molding equipment, in addition to the improvement or improvement of traditional injection molding equipment in order to adapt to the new injection molding process, it has also greatly improved the automation of injection molding auxiliary machinery, energy-saving injection molding machine technology and mold technology, and the development of special injection molding machines. For example, the all-electric injection molding machine is a very functional injection molding machine, which is gradually being promoted at this stage.

In addition, the computer technology that supports injection molding has also made great progress. Such as the use of computer-aided engineering technology for injection molding flow state analysis, temperature field analysis, product residual stress analysis, product warpage and shrinkage deformation analysis.
