the installation place ofcell phone jammer

Amorphous substances increase the temperature to see added to the heat, but increasingly presented as the liquid. Before the rise in temperature to the melting point, crystalline plastic material can maintain the strength and hardness unchanged. The small-power cell phone jammer needs to be installed with directional antenna in some situations.
The additional heat required to heat of fusion when melting destruction of the crystal structure, while the temperature remains constant until the melting end. With the plastic in the mold cooling, heat of fusion released from the mold out to be dissipated. However, as the temperature decreases, the molding stability and hardness, to quickly improve, the workpiece can be quickly removed from the mold. Therefore, crystalline plastic is more suitable for short-cycle molding. Compact structure means that a larger volume change from the melt to the solid crystalline plastics. Therefore, crystalline plastic amorphous plastic molding shrinkage usually the former is greater than one per cent, while the latter is about 0.5%. The testing method of cell phone jammer is as follows.
The high crystalline plastic shrinkage makes it to estimate the complexity of the cavity size, but the benefits also contribute to the stripping of the workpiece. The typical mold shrinkage are listed in Table 2. When the melting of crystalline plastic, they tend to become highly liquid technology. Nylon resins because of their good flow characteristics known so slender and thin cross-section requirements of the application. On the other hand, people also know that they are more prone than the high viscosity of the amorphous resin flash. Some of the plastic is not subject to the influence of moisture, especially those hydrocarbons (in addition to carbon and hydrogen there is no other element) plastic such as polyethylene, polypropylene and polystyrene. Other plastic to absorb the different water, even at room temperature for absorption. The applicable location of cell phone jammer  contains the school and jail/work camp. cell phone jammer can stop the mobile communication in the specific range, Forming the workpiece in the absorption of water will lead to size changes, so the water can also be seen as a plasticizer or toughening agent. The absorption of water may be evaporated in the injection molding process, resulting in waterlines and bubbles. Some resin may be in the melting temperature and water react. This reaction is called hydrolysis, which is a form of degradation. It makes the molecular weight decrease, leading to the melt viscosity decreases, the loss of impact strength. The sensitivity of the hydrolysis does not depend on how much of the water absorption of the plastic resin. In fact, when the nylon resin to achieve a relative humidity of 100% saturation, they can absorb up to 8% or more moisture. Nylon slow hydrolysis in the melting temperature than polyester or polycarbonate, polyester or polycarbonate water absorption is much less than it.
