Let's look at the mechanical sequence of a side-action slider system. Phase one is mold opening: the heavy clamping wedge backs off immediately, freeing the slider. Phase two is extraction: the stationary angle pin forces the slider to slide laterally along the wear plates, clearing the plastic undercut. Phase three is retention: the pin leaves the slider housing completely, and internal spring plungers hold the slider steady so it doesn't drift. During mold closing, this entire cycle reverses smoothly to seal the cavity for the next shot."
Course Description
This master course is designed to provide practical and industry-oriented knowledge of plastic injection mold design. The course covers complete mold fundamentals, real mold assembly, defect analysis, and manufacturing workflow using simple explanations and real examples.
You will learn how molds are designed, assembled, disassembled, and tested in actual mold shops. The course includes hands-on role-play concepts, real mold components, CAD understanding, and common molding defects with remedies.
This course focuses on practical skills, not just theory, making it ideal for engineers who want to work confidently in mold design and manufacturing environments.
Learn to design mold core and cavity split by defining parting surfaces and direction, manage drafts, shrinkage, undercuts, and wall thickness to prevent flashes, leaks, and ejector issues.
Explore the three-stage slider ejector system in plastic mold design, including cavity and core sides, undercuts, and the role of angle pins for part release, cooling, and mold opening.
Explore common molding defects and how to fix flash, sink marks, and short shots. Learn gate and venting, cooling, uniform wall thickness, melt temperature, and injection speed.
Mold Design has been one of the most demanding for career avenues in the Mechanical Engineering field. Blood and sweat have been poured in for the creation of this course. Mold design comprehensible to the students, corporate professionals as well as beginners and stalwarts in the plastic products manufacturing Industry.
Theoretical knowledge of the Injection Molding process is readily available in this course. Self-evaluation and review tests will examine the knowledge gained. Lecture duration has been kept short to help students not to lose interest.
Overall, it is a complete package starting from the basics to the documentation or 2D drawing process, not to forget the discussion pertaining to mold defects, their causes, and remedies.
As a topping on the cake, the instructor has come up with a PROJECT which will commence its journey from mold base, up until the creation of Feed System, Ejection and Cooling systems.
