Lesson 6: Clamp Tonnage

Optimizing fill speed, switch-over points, and packing pressure profiles are all essential to producing high quality molded parts. These factors also influence clamp tonnage requirements during the filling and packing phases, which is our focus in this lesson.

Topics covered in this lesson include: what influences clamp tonnage requirements, how changes in fill speed and injection pressure affect clamp tonnages, the impact of packing pressure profiles on clamp tonnages, and the risks of reducing packing pressure at switch-over to lower clamp tonnages.

Goals of Processing: Filling Phase (Level 1): 

  • Learn the fundamentals of process optimizing by analyzing the filling phase of molding a part
  • Gain an understanding of how part design, mold design, and process are connected and interdependent
  • Analyze real-life molded parts and learn the cause and effect behaviors of design and process

Section Description: 

Molding high-quality parts is dependent on many factors, including skillful part and mold design, an understanding of polymer material behavior, and an optimized process. It is important for injection molding processing engineers to follow key steps to ensure consistently high-quality molded parts.

Explanations, simulations, cause and effect analyses, and various filling phase variables are covered in this section.
