Lesson 6: Film Gates

Gate style, size, and placement are important aspects of mold design. In this lesson we will learn about film gates how they are used with various parts.

This lesson covers when and why to use film gates in mold designs, how to evaluate filling behavior using film gates of different sizes, and how film gates of various shapes and sizes impact injection pressures, packing and cooling behaviors, and clamp tonnages.

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.
