In view of the actual operating mode,analyzed the correct meshing condition to the compound gear and the pin-track,in order to realize the high production and highly effective has laid the f.

The conditions of the scale-up with the method of thermal transmission,compounding and Maddock to the melted resin in the intermeshing corotating twin-extruder were analyzed with the method of equivalent diameter and three groups of mathematical relationships about the main parameters were obtained.

Solid particulate conveying characteristic is given by backwards leakage flow rate through intermeshing region and formulated as a conveying efficiency d.

The mathematical models of the cross section,the 3-D figure and the curve of form cutter of the extrusion press which is corotating intermeshing,conjugation and twinscrew are proposed,and the equation of parameter cueves family is derived that is suitable for the design of the cross section of screw.
