Gate placement is an important aspect of mold design in order to achieve optimal part quality. In this lesson we will focus on edge gates, specifically standard, lapped, and chisel styles.
This lesson covers three different types of edge gate systems, including standard, lapped and chisel edge gates. The advantage and disadvantage of each system are discussed as well as how they impact injection pressures, shear rates, pack 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.
