Lesson 9: Cashew Gates

Injection molded part quality is highly dependent on gate designs, sizes, and location. Because cashew gates, also called banana gates, can be placed in areas that are not visible, they are an option for molded parts that require perfect surface quality.

Topics in this lesson include: what cashew gates are and when they should be used, why polymer materials are an important factor in determining the viability of using cashew gates, and how different gate designs affect injection pressure requirements, packing pressure, clamp tonnage, and gate cooling behavior.

Goals of Mold Design: Gates (Level 1): 

  • Learn the basics of mold design and how various design elements impact a molded part
  • Gain an understanding of various gate styles and how they influence the molding process
  • Analyze real-life simulations and learn to determine optimal outcomes

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.
