Gate design and placement are key factors in mold design. In the first part of this lesson we will learn about sub-gates, also called tunnel gate systems, specifically round and oval sub-gates.
The first part of this lesson covers when and why sub-gates are used in mold design, how different gate designs and sizes impact injection pressures, and how to evaluate shear rates using different gate styles.

Goals of Mold Design: Gates (Level 1):
Section Description:
Gate design and placement are key factors in mold design. Types of gates, placement, and size significantly affect the outcome of molded part so should be understood for maximum benefit. Placement options for gates are often limited by design restrictions and other part-related constraints, understanding and utilizing industry best practices are useful in achieving optimal results.
Explanations, simulations, cause and effect analyses, and the uses of various design features are covered in this section. Understanding these design features is important because they influence the moldability, function, appearance, and quality of a part.
