There are many reasons for the sticking and poor demoulding of injection molding products, and mold failure is one of the main reasons. The causes and treatment methods are as follows:

In the production process of plastic products, injection molds can be described as an extremely important component. The quality of injection molds is not only directly related to the integrity of plastic products and the accuracy of dimensions, but also determines the production cost and economic benefits of enterprises, so the use of sophisticated modern technology to produce high-quality molds is particularly critical.

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.

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.

The lightweight performance of PEEK materials and the comprehensive performance potential behind them are exciting. PEEK offers some representative products for the aviation industry, such as the PEEK polymer injection molded parts used to replace the expensive production of aluminum brackets.

Injection molding factories often encounter products with insufficient gloss when processing injection molded parts. Low gloss means the surface is dark and dull, and the transparency of transparent products is low. There are many reasons for poor gloss. General product surface gloss defects can be divided into the following three types: mold failure, improper molding conditions, improper use of raw materials.
