Injection molding is an important way of plastic products, suitable for mass production of complex shapes, precise size requirements of plastic products. With the change of the application range of plastic injection molding products, the requirements for product quality are becoming higher and higher. In molding, the process parameters directly affect the flow state of the melt in the mold and the quality of the final product, so obtaining and maintaining the optimal process parameters is the premise of forming high-quality products.
The complete injection process includes four main stages: plasticizing, filling, pressure holding, and cooling. When the mold is closed, the raw plastic material is plasticized and injected into the cavity. When the plastic is filled with the cavity, a certain pressure is maintained, and appropriate plastic is continued to be injected into the cavity. After the pressure is maintained, the mold is cooled for some time, and then the product is pushed out from the mold and enters the next molding cycle.
They are becoming higher and higher to the requirement of the mold; the traditional mold design method has been unable to adapt to today’s requirements.
Injection molding has become the most plastic product used in molding technology. With the application of plastics in People’s Daily life and industrial production, as well as various advanced fields, the requirements for the quality of parts are getting higher and higher, and the efficiency of the whole molding process is also required to be improved. Therefore, it is more urgent to obtain the best conditions for the molding process in a shorter time.
To ensure the quality of injection molding parts, Aria has introduced advanced gas-assisted injection molding technology. Visit Aria’s website to get an injection molding quote online.
The benefits of gas-assisted injection molding technology are mainly reflected in the following categories of products:
- Tubular and rod parts
it is such as door handle, swivel chair support, hook, armrest, guide rail, clothes hanger, etc. This is because the tubular design makes the existing thick section suitable for generating gas piping, which uses the gas penetration to create a hollow, thereby eliminating surface defects, saving material, and shortening the molding cycle.
- Large flat parts
such as car door panel, copier casing, instrument panel, etc. The stiffener is used as the air passage to eliminate the surface defects such as warping deformation and collapse of melt accumulation caused by the stiffener and residual stress inside the parts and increase the ratio of strength/stiffness to mass.
At the same time, the tonnage of the injection machine can be reduced greatly due to the reduction of mold locking force. For complex parts with complex shapes, uneven thickness, and defects such as shrinkage marks and stains caused by traditional injection molding techniques, such as bumpers, home appliance shells, car bodies, etc.
In the production of these products, through the use of gas-assisted injection technology and clever arrangement of the airway, appropriately increase the number of reinforcing bars while using gas pressure to overcome the possible defects so that the parts of molding not only simplify the process but also reduce the production cost.
