Abstract: This article explores the characteristics of various mold structures in extruders through tread
extrusion experiments, and meticulously analyzes the profound impact of these different mold types on the
overall performance of extruded products. By comparing and analyzing experimental data, the performance
metrics of conventional die molds and thickened die molds in extrusion operations are examined. Based on
this, a systematic evaluation is conducted on the control of porosity, enhancement of composite viscosity,
optimization of thickness uniformity, improvement of surface adhesion, and promotion of overall production
efficiency achieved by these two types of molds. The research results show that when the tread structure form
is well matched with the selection and design of die molds, it can significantly improve the qualification rate
and production rate of extruded products, thereby comprehensively upgrading product performance while
generating profits for enterprises.
Key words: thickened mold; compactness; adhesive force; quality uniformity; efficiency
