| Precision injection molding machine refers to molding machinery equipment suitable for the production of precision plastic products. Usually the precision injection molding machine has two indexes: one is repeated deviations of product size, another is to repeat the weight deviation products. Because of the size and thickness of different and difficult to compare products. The latter represents the comprehensive level of injection molding machine, repeating weight error of ordinary injection molding machine at about 1%, the better machine can reach 0.8%, lower than 0.5% for precision machine, less than 0.3% for the ultra precision machine. As mentioned before, precision injection molding machine product size precision requirements within 0.01 ~ 0.001mm, many precision injection also requires the injection molding machine with high injection speed injection pressure, higher requirements; clamping system has enough rigidity and precision of mold locking, the locking precision is a clamping force uniformity, adjustable, stability and repeatability, the mold opening and closing position accuracy requirements are high; precise control to the corresponding accuracy of pressure, flow, temperature, measurement, the multi-stage injection, to ensure the reproduction and molding process of the repeat accuracy etc.. |
