double injection mold:
Injection molding is a molding method of injection and molding, also known as injection molding. The general injection molding method is to put the pellets or powder of the polymer component into the barrel of the injection molding machine, and after heating, compression, shearing, mixing and conveying, the material is homogenized and melted. This process is also called plasticizing.
Then apply pressure to the melted polymer melt by means of a plunger or screw, and the high-temperature melt will be injected into the pre-closed low-temperature mold cavity through the nozzle in front of the barrel and the runner system of the mold, and then After cooling and shaping, the mold can be opened, and the product can be ejected to obtain a plastic product with a certain geometric shape and precision. Due to the strong adaptability of injection molding process, short molding cycle and high production efficiency, injection molding products have been widely used in various industries such as automobile manufacturing, electronics, medical treatment, and daily necessities.
2. Injection molding machine and its working process
The injection molding machine is mainly composed of mold clamping system, injection system, heating and cooling system, hydraulic system, lubrication system, electric control system, safety protection and monitoring system. The injection molding cycle is mainly composed of procedures such as mold closing, injection seat moving forward, injection holding pressure, pre-molding metering, cooling, mold opening, and product ejection.
The injection molding process is a complex process involving many factors such as materials, molds, injection machines, and molding processes. The appearance of defects in injection molding products is inevitable, so it is particularly important to seek the internal mechanism of defects and predict the location and type of defects that may occur in products, and use them to guide mold design and formulate more reasonable process operating conditions.
3. Typical defects of injection molding
Generally speaking, there are three main aspects to evaluate the performance of plastic products:
The first is appearance quality, including integrity, color, gloss, etc.;
The second is the accuracy between size and relative position, that is, dimensional accuracy and position accuracy;
The third is the mechanical properties, chemical properties, electrical properties, etc. corresponding to the application, that is, functionality.
Therefore, if there is a problem in any of the above three aspects, it will lead to the generation and expansion of product defects
