Plastic parts are widely used as shell and internal components of electronic products, which are a large category of plastic parts.

Electronic products cover a wide range, it has been deeply applied to all walks of life and our daily life. It mainly includes:

A. Computer and communication products — mobile phone, computer, telephone, headset, smart watch;

B. Digital electronic products —- audio, camera, DVD, power supply;

C. Office products — printers, scanners, projectors, videophones, attendance machines;

D. Home electronics – doorbell, TV, smart door lock, electronic scale;

E. Medical care – sphygmomanometer, thermometer, monitor;

F automobile electronics and peripheral products — automobile charger, emergency starting power supply, rear-view mirror;

G. Industrial Electronics – monitor, thermometer, hygrometer, pressure gauge.

H. Others such as electronic toys, environmental protection equipment, solar energy, sports fitness equipment, etc.

Tips of injection molding process for the plastic parts used in electronic products: 1. Mold making A. Select the right steel to make the mold: For high gloss surface and corrosive plastics, steel with high chromium content should be selected as the core, such as S136. For common surface parts, p20718 and other steels are generally selected as die cores. B. The position of the glue inlet should be selected reasonably, and the exhaust of the mould cavity should be reasonable and sufficient. C. For parts requiring post-treatment such as silk screen printing, electroplating or pressing copper nuts, the reserved clamping position shall be considered. D. Select the correct mold processing technology: for the parts with high size or surface requirements, the mold cavity should be finished, using high-precision CNC, slow wire cutting and mirror EDM to finish machining the cavity. 2. The precautions on electronic product plastic parts injection molding A. The barrel of injection molding machine shall be clean. Especially for appearance parts, there shall be no color mixing, speckles and materials. B. For high gloss parts or parts that need to be electroplated, there must be no scratch, and the surface shall be protected by film. C. For the parts with sealing requirements, the parts shall be free from deformation, and the sealing surface shall be clean without more or less glue on the edge. D. Parts working in high-pressure environment shall be free of edge, sharp angle, bubble and crack. E. For parts with large output, automatic production line of manipulator should be considered.
