Lesson 3: 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 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.
