High-quality pin headers are manufactured through a variety of processes. Each pin header is subjected to a process called injection molding. The temperature effect is most important during the injection molding process. High and low will directly affect the quality of the entire product. This article mainly explains the four effects of high temperature during the injection molding process of the pin header connector. I hope everyone can have a better understanding of the processing technology of the pin header.
I. Affecting the thermal deformation of the machine. When the temperature of the pin header connector is too high, the moving parts with different thermal expansion coefficients in the hydraulic component are stuck due to the smaller clearance of the matching gap, causing malfunction and affecting the transmission of the hydraulic system. Accuracy, which leads to factors such as poor working quality of components.
II. The effect of the deformation of the rubber seals Shenzhen Zhengling Sunshine Technology experts found in the actual test of the temperature of the injection molding process of the pin header connector, the temperature rise of the injection molding machine will cause the rubber seal to deform and accelerate the aging failure. , to reduce sealing performance and service life, and cause adverse consequences of leakage.
Third, the effect of accelerating oil oxidation and deterioration The high temperature rise of the injection molding machine during the processing of the pin connector will accelerate the oxidation and deterioration of the oil, precipitate the asphalt material, and reduce the service life of the hydraulic oil. The precipitates block the damper orifice and the slit valve port, causing the pressure valve to be stuck and unable to move, the metal pipe being elongated and bent, or even broken.
4. The effect of the viscosity reduction of the oil The excessive temperature rise of the injection molding machine during the processing of the pin connector will result in a decrease in the viscosity of the oil, an increase in leakage, a significant decrease in the volumetric efficiency of the pump and the efficiency of the entire system. As the viscosity of the oil is lowered, the oil film of the moving parts such as the spool is thinned and cut, and the frictional resistance is increased, resulting in an increase in wear.
Four effects on the temperature of the pin header connector during the injection molding process are introduced here.
