CDMA signal can be shielded by cell phone jammer .
PC + ABS: fluidity, strength, good, moderate price. For the vast majority of mobile phone shell, as long as the more optimal structural design, strength is guaranteed. More commonly used GE CYCOLOY C1200HF. PC: high strength, expensive, poor liquidity. Suitable for higher intensity housing (such as the clamshell phones and the shaft with two shells, with no standard slide rail module and slide rail unit has two shells, at present, must be specified with PC material). More commonly used GE LEXAN EXL1414 and Samsung HF1023IM. The application of the material to note the following points: avoid blindly reduce the intensity of risk, and what parts are a result of molding material with PC problems and increased costs; not fully grasp the intensity in the case of mold assessment Tooling Review should clearly tell the mold suppliers, may be produced using T1 PC + ABS products, but does not rule out the time when the strength is not enough follow-up will be the possibility of switching to PC material.
Cell phone molds copy number: 8 to 12 sets, depending on the specific circumstances of specific products, and another button silicone mold; mold core material: NAK80, S136H, imported 738 + heat. Components: two parts connected by rail Slider. There are two ways you can slide the rails, one is in the slide part and host part of the two shells were made on the rails and slide the two shells through the track with each other, in between the shell preload on the spring to enhance the sliding handle. cell phone jammer can control the range of about 40m (diameter).
This slide method for the manufacture of the shell mold need to increase the slider, and the manufacture of high precision track, but the phone can be designed to be thin.Another way is to slide the slide using standard modules, the slide and slide in the slide were fixed part and host part of the two housing. Movement between the two parts and fixed entirely on rails module to complete. Advantage of the manufacturing of the shell does not require the disadvantage of mobile phones will increase the thickness of about 2.7mm or so. cell phone jammer can be installed on various places according to the installation specification needs, including the wall, ceiling and so on.

The agent has purchased several new types of cell phone jammer
The agent has purchased several new types of cell phone jammer .
Authoritative statistics show that the global mobile phone users to replace the cycle average of 2 years or so, and in some economically more developed countries, mobile phone users to replace a shorter period. For example, in Japan, although many mobile phones have signed six-year service contract, but a number of mobile users in the use of a cell phone for six months or a year later will be replaced with a new feature phone. DoCoMo, for example in 2002, sold 25.3 million of its handsets, approximately 15.2 million (60%) has been replaced in 2003 by the user. Another survey shows that mobile phone penetration rate in Beijing has reached 81%, and 60% of the users of mobile phones replaced, the replacement cycle of approximately 1 year. Ministry of Information Industry forecasts, given China's mobile phone market is in a period of rapid development, the current national phase-out old phone is estimated at more than 20 million per year. As the Internet age high-tech garbage, used cell phone and cell phone batteries caused a great deal with the crisis. The cell phone jammer has the cooling function.
Mobile phone battery and other accessories, such as containing arsenic, mercury, antimony, nickel, tin, gold, lithium, cobalt and some other toxic metals. The main cause of nickel poisoning respiratory system damage, severe blurred consciousness and even coma, complicated by myocardial infarction. Elements of the body not cadmium is harmful environmental laws strictly control the metal, it will make people's intake of emphysema, bone changes and anemia. Japan has found that certain areas due to long-term consumption of contaminated high nickel content of rice and water, pandemic disease, bone pain occurred. If the phone and its battery was abandoned after no treatment, or a buried it, it will seriously pollute the soil and groundwater resources, easy to make people, especially children suffering from cancer and neurological disorders. If you choose to burn, it will cause air pollution, and ultimately the formation of acid rain into the soil. Pollution and waste battery treatment is most concerned about the social focus of environmental protection, so from an environmental point of view, the implementation of used mobile phone battery recycling green science is very necessary. Although the old mobile phones and batteries will give the environment pollution, but through the implementation of a responsible recycling program can make it into a valuable resource. Through careful processing, mobile phones and batteries can be used to extract gold, silver, copper, cobalt, lithium and other precious metals, re-used for industrial production. More fans will be added to the cell phone jammer .
