The area along pointing direction of directional antenna of cell phone jammer

Make sure the entire production process, testing methods, to ensure product reliability. A plastic material selection of ways to understand the performance of plastic engineering plastics molding sometimes appeared very strange. The area along pointing direction of directional antenna of cell phone jammer  will be the area where the shielding signal will transmit farthest.
The answer to a molding problem may be completely different from another molding. This may be because of these examples involve two essentially incompatible with the plastic resin. This paper will these materials the nature of the differences between the various materials to be discussed, in order to enhance the understanding of the mechanism of the injection molding process. Measurement and control of the injection in the injection molding is very important. Although these measurements are relatively simple, but the majority of injection molding machines are not enough temperature sampling point or line. In most injection molding machine, the temperature by the thermocouple sensor. A thermocouple is basically composed of two different wire tail phase. If one end than the other end of the heat, will produce a tiny telecommunications; more heated, the stronger the signal. Use many cell phones of various frequency channels to test shielding effect of cell phone jammer  at site.
Temperature control thermocouple is also widely used as sensors for temperature control system. In the control apparatus, set the desired temperature, the sensor and the set point temperature is compared. In this simple system, when the temperature reaches the set point, it will turn off power after the temperature dropped again to open. This system, known as the opening and closing control, because it is either on or off. ? molten plastic temperature of the melt temperature is very important, the use of radio material cylinder temperature is only guidance. Melt temperature can shoot the mouth at the measure or the use of air injection method to measure the The injection cylinder temperature setting depends on the melt temperature, screw speed, back pressure, shoot feeding quantity and injection cycle. According to this, the position of cell phone jammer  can be predicted when doing the honeycomb position arrangement in the large area.
If you are not processing a particular level of plastic experience, please start from the lowest setting. In order to facilitate control, shooting material cylinder sub-district, but not all are set to the same temperature. If the operation time is long or operating at high temperatures, set the temperature set to a lower value, which will prevent plastic premature melting and diversion. Before the start of injection, to ensure that the hydraulic oil, closed hopper, mold and shoot material cylinder in the correct temperature?
