Injection molding requires the use of plastic as raw material to make product parts with a certain shape.
In the manufacture of connectors, the plastics used are often engineering plastics with high strength, high toughness and temperature resistance such as PC, PA, PBT, etc. It is crucial to choose the right plastic, which is related to the stability of product performance, the aesthetic quality of appearance and the control of manufacturing costs. During the injection molding process, it is necessary to pay attention to controlling parameters such as injection pressure, temperature and speed to ensure the quality and stability of connector molding.
1. Equipment
Injection molding equipment consists of injection molding machine, mold, heater, cooler, etc.
2. Process flow
(1) Put the pre-processed plastic particles into the hopper of the injection molding machine and enter the heating cylinder through the screw for melting treatment.
(2) The molten plastic is pumped into the mold through the heating pump to fill the entire mold.
(3) The molten plastic injected into the mold is cooled and the finished parts are pulled out of the mold.
(4) Check the quality of finished parts and components. If there are any unqualified products, they need to be classified and processed.
3. Quality control
During the injection molding process, it is necessary to manage and control factors such as the ratio of raw materials, the control of the molding process, the use and maintenance of the mold. At the same time, the quality of the finished parts and components needs to be inspected and evaluated during the production process, and a series of scientific quality management methods are used to ensure the stability, reliability and comprehensive performance of the products.
The above is a detailed introduction to the process production injection molding of connectors. The injection molding process has become the main process in connector manufacturing due to its advantages of high production efficiency, short production cycle and stable product quality. During the production process, attention should be paid to material and process control to ensure the performance and quality of the product.
