The perspective in this note explores rationally defined scaling parameters for injection molding to account for the length and thickness of parts, the melt temperature, the injection pressure, and the injection speed: Injection‐molding parameters, first empirically established for 4‐ to 5‐mm‐thick parts, were later experimentally optimized for 2‐ to 3‐mm thick parts. The push for even thinner parts required major adjustments in molding technology, including the use of lower‐viscosity materials. This shift from thicker to thinner parts was arbitrarily characterized by the length‐to‐thickness ratio of the part, which is shown to be incorrect.

薄壁成型的缩放比例考虑

本说明中的透视图探讨了为注塑成型合理定义的缩放参数，以考虑零件的长度和厚度，熔体温度，注塑压力和注塑速度：注塑成型参数，首先根据经验确定为4-5毫米厚的零件，后来经过实验优化为2至3毫米厚的零件。为了生产更薄的零件，需要对成型技术进行重大调整，包括使用低粘度材料。从较厚的零件到较薄的零件的这种变化是通过零件的长厚比任意确定的，这是不正确的。
