Nine major properties of polyimide (PI) Thermal stability: decomposition temperature from 500 ° C to 600 ° C Mechanical properties: The tensile strength is generally 100MPa
plastic gears and electrical shells are products that are widely used in our lives, and they also carry forward the benefits of being very stressful in our lives. For example, many plastic products used in our lives are required for plastic processing in Changzhou, and injection molded parts widely used in the machinery industry will also need to be processed for injection molded parts. Friends may encounter deformation when processing injection molded parts, so this time I will briefly talk to my friends about this question.
Injection molding processing from plastic particles to molding injection molding products needs to go through a series of rigorous processes, and the lack of mastery of any process in the middle will lead to product quality problems, which are shared as follows.
Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature of the first two passes mainly affects the plasticization and activity of the plastic, while the latter temperature mainly affects the activity and cooling of the plastic. Each kind of plastic has a different activity temperature, the uniform plastic, because of the source or grade difference, its activity temperature and differentiation temperature are different, this is because of the equilibrium molecular weight and molecular weight dispersion difference, the plasticization process of the plastic in the injection machine of the different example is also different, so the temperature of the selected barrel is not similar.
Objects created during the molding process are known as moulded parts. This method involves injecting molten material into a cavity or mold, allowing it to cool, harden, and take on the desired shape.
It is possible to CNC mill plastic. Actually, one common method for producing plastic parts fast, precisely, and with a high level of precision is CNC machining.
