Gate design and placement are key factors in mold design. In the third part of this lesson we will learn about ejector pin sub-gates as another design option.
The third part of this lesson covers when and why ejector pin sub-gates are used in mold design, different ejector pin styles and the advantages/disadvantages of each, and how different gate and pin sizes relate to injection pressures and clamp tonnages.

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 a molded part, so they should be understood for maximum benefit. Because gate placement options are often limited by design restrictions and other part-related constraints, understanding and utilizing industry best practices is useful in achieving optimal results.
This section covers explanations, simulations, cause-and-effect analyses, and the uses of various design features. Understanding these design features is important because they influence a part’s moldability, function, appearance, and quality.
