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 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.
