Micro Molding

 Advantages of Micro Molding

 

  • Due to small dimentions, the number of cavities reduced, is conducive to improving the mold balance, improve product appearance size accuracy
  • Control mold temperature stability, in line with precision molding requirements, but also saves the mold heating / cooling required energy
  • Wide range applicated to small electronics

Feature of Micro Molding

 

The main features of micro-injection molding products are small size, special shape, complex functional area. In general, the size of the order of several microns to several centimeters, aspect ratio between 1 to 100, the individual functional areas require high strength, high brightness, high transparency and so on. In order for these features to be able to reproduce with high reproducibility, the process must meet some special requirements. Specifically, in order to ensure proper filling, high injection rates and high injection pressures (in the hundreds to thousands of kg / cm2) are required. The temperature of the material is as high as possible within the allowable range. Should be controlled at high end. In order to obtain a sufficiently large amount of injection, it is necessary to use a large runner and a large gate, which ensures that the polymer is reliably controlled and switched during the flow process to avoid material degradation. The mold requires a special split heating and cooling system to dynamically control the mold temperature.
