Lesson 3b: Round and Oval Six-Gate Sub-Gates

In the second part of this lesson, we will continue to learn about round and oval sub-gates, focusing more specifically on six-gate systems and how they compare to the dual-gate systems from the first part of this lesson.

The second part of this lesson covers round and oval sub-gates and how they impact injection pressures, how to evaluate shear rates using different gate styles, and a comparison of injection pressures between dual gate and six gate set-ups.

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.
