What are the problems that need to be paid attention to in injection mold processing when designing flange shaping molds?

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.

The production of injection molding products, need to use injection molding molds, generally under normal circumstances, plastic products produced by this injection molding method, the surface has a better gloss and color, but sometimes it is inevitable that there will be some shortcomings, in addition to the material problems of the plastic itself, colorants and the gloss of the mold surface, what are the reasons for injection molding processing to cause such an impact?

The injection molding process of injection mold can be roughly divided into three steps, first, temperature mastery; Second, pressure mastery; Third, the cycle of molding.

PSU has a wide range of applications. In the field of electronics and electricity, PSU can be used to make various electrical parts such as contactors, connectors, transformer insulators, thyristor caps, insulating sleeves, coil bobbins, terminals and slip rings, and printing Circuit boards, bushings, covers, TV system parts, capacitor films, brush holders[1], alkaline battery boxes, etc.; in the automotive and aerospace fields, PSU can be used to make protective cover components, electric gears, battery covers, detonators, Electronic ignition device components, lighting components, aircraft interior parts and aircraft exterior parts, outer protective covers of aerospace vehicles, etc. It can also be used for PSU to make luminaire baffles, electric transmissions, sensors, etc. The demand for polysulfone polymers used to make cabin parts in the world market continues to grow.

Turn-milling composite machining is a way of mechanical processing, turn-milling composite machining is not simply the two processing means of turning and milling into a machine tool, but the use of turn-milling synthetic motion to complete all kinds of surface processing, is a new cutting theory and cutting technology produced under the condition of the greater development of numerical control technology;
