Principle introduction of cell phone jammer should be described in details

Sparking of cell phone jammer when starting can be effectively avoided.
Such as the suppression mode (open-type, semi-closed-formed, closed-type), casting dies, injection molds. Select the desired mold structure is to determine the necessary molding equipment, the ideal number of cavity, absolutely reliable under the conditions in the mold itself can work to meet the plastic parts of the process technology and production economy. Plastic parts of the process of technical requirements is to ensure that the plastic parts of the geometry, surface finish and dimensional accuracy. Production of plastic parts to make the economic requirements of low cost, high efficiency, mold can continuously work, long life, to save labor. Affect the mold structure and the many factors that mold the individual systems, very complex: the cavity layout. According to the geometry characteristics of plastic parts, dimensional accuracy requirements, batch size, ease of mold manufacturing, mold costs to determine the number and arrangement of the cavity. Principle introduction of cell phone jammer should be described in details.
For the injection mold, the plastic parts precision level of 3 and 3a, the weight is 5 grams, with hardening casting system, taking the number of cavity 4-6; plastic parts for the general accuracy (4-5), forming materials for the local crystalline materials, several desirable cavity 16-20; plastic parts weighing 12-16 g, cavity number to take 8-12 months; and weight of 50-100 grams of plastic parts, take a few cavity 4-8. Plastic parts for the proposed amorphous cavity number 24-48, 16 - 32 and 6-10. When the weight of plastic parts and then continue to increase, it is rarely used multi-cavity mold. 7-9 precision plastic parts, up to a few cavity 4-5 than that of plastic precision level increased to 50%. Determine the sub-surface. Sub-surface location should be conducive to mold, exhaust, mold and molding operation, the surface quality of plastic parts. cell phone jammer is more needed in places which require to be explosion-proof and tamper-proof.
To determine the gating system (main runner, runner and gate sub-shape, location, size), and exhaust system (exhaust means the exhaust slot location, size). Select the top the way (mandrel, pipe jacking, push plates, combined ejector), decided to undercut treatment, core pulling way. Determine cooling, heating, and heating and cooling groove shape, location, installation of heating element parts. According to the mold material, strength calculation or empirical data, to determine the thickness of the mold parts and dimensions, shape structure and all the connectivity, position location, position-oriented pieces. Identify the main molding parts, structural parts of the structure. Consider the strength of the various parts of the mold, forming part of work calculated size. These problems are solved, the mold structure naturally resolved. At this time, the mold structure should begin to draw sketches, prepare for the official drawing.
