The importance of temperature for injection molded parts
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.
It is to the injection mold cavity injection mold injection injection accurate measurement of plastic melt, in the special nozzle to the melt injection of compressed gas, gas in the Rong body less ductility direction forward, push the melt to fill the cavity and the melt to maintain pressure, when the pressure of the gas, injection time is appropriate, the plastic will be pressed by the pressure gas on the cavity wall, forming a hollow, complete plastic parts, after the plastic melt cools and solidifies to discharge the gas in the melt, open the mold to exit the product.
The temperature control of injection molding processing is also very strict, which is an important and difficult step, so special attention is required. Now let's take a look at the temperature control of injection molding processing.
1. The mold filling process adopts one-dimensional heat conduction, and the corresponding cooling is also one-dimensional cooling.
2. After the high-temperature fluid enters, the specific heat capacity and its own thermal conductivity of the molded product remain unchanged.
3. In the process of product molding, abrasives and plastic parts are in a constant temperature field.
4. In a constant temperature field, when the core temperature is equal to the temperature at the time of thermal deformation of the plastic, the entire cooling cycle ends. This also shows that the upper and lower limit points have two functions. According to different injection molding requirements, the temperature of its upper and lower limits is also different, so in many cases it is necessary to analyze specific problems.
The above is the relevant introduction to the temperature control of injection molding processing. In the injection molding process, the temperature control is crucial, if the temperature control is not good, it will directly affect the quality of the product. Here you can do a simple understanding of injection molding, because many injection molded parts are very important in our lives, but to ensure the quality of the product, it is very important to control the processing, so I hope these can help everyone.
