摘　　要：将理论的最小冷却时间（ＴＭＣＴ）用于塑料异型材挤出定型模长度设计，能反映各种因素的影响，可作为开发高速挤出的依据。本文给出了该理论在挤出定型模长度设计中的计算公式及其推导过程，并用两个实例说明其具体应用。AbstractThe theoretical minimum cooling time (TMCT) used in the design of the length of the calibrating tool for plastic profile extrution can reflect the effects of various factors, and it is regarded as the basis for developing high speed extrution. The formulas for the design of the length of the calibrating tool and their deduced processes are given in this peper on the basis of TMCT theory. In addition, two applicable examples are introduced.
