On the process of injection molding

Release date:2018-07-05 00:00 Source:http://www。dljinghe。com Views:

In the injection mold, the design of cooling system is very important. This is because molded plastic products can only be cooled to a certain degree of rigidity. After being demolded, plastic products can be prevented from deformation due to external forces. As the cooling time accounts for about 70% ~ 80% of the whole molding cycle, a well designed cooling system can greatly shorten the molding time, improve the injection productivity and reduce the cost.


In the injection process, the pressure at the nozzle of the injection molding machine is the highest to overcome the flow resistance in the whole process. After that, the pressure is gradually reduced along the flow length to the front of the melt, and the final pressure in the front of the melt is the atmospheric pressure if the exhaust is good inside the cavity.


For an injection factory, the energy consumption occupies about 60% of the injection molding process, so it is an important way to effectively reduce the energy consumption of the injection molding machine. With the continuous improvement of the energy saving technology of the injection molding machine, the reduction of the overall energy consumption of the injection plant needs to be considered from the aspects of production management, processing technology and materials, and the production workshop.


Injection molding in Dalian is a highly specialized molding process by injecting hot and thermoplastic thermoplastic or thermosetting materials into a relatively cold mold cavity. Selecting suitable die steel is very important for mold performance and overall production benefit. Injection molding is a kind of production behavior that plastic particles are molded into predetermined shapes by heating and melting. In this process, there are many production factors that have an important impact on the quality and efficiency of the final plastic products.
