Gating & Riser Design


Basics of Fluid Dynamics for Metalcasting Gating Systems

This module examines the basics of fluid dynamics for metalcasting gating systems and defines fluid flow in gating systems. This module also defines the laws of fluid dynamics and the effects of momentum and turbulence on gating systems. By the end of this module, you will be able to describe the basics of fluid dynamic principles related to gravity fed metalcasting gating design. (0.1 CEU)

Basics of Heat Transfer Principles for Riser Design

This module explores the influence of heat flow, identifies the two types of solidification and explain how shrinkage occurs. This module also looks at how shrinkage occurs differently in various metalcasting alloys. By the end of this module, you will be able to explain the influence of heat flow and identify the effects of different alloys on risers. (0.1 CEU)

Functions and Features of a Rigging System

Riser function, riser types and their features, gating system functions and features, and riser sleeves and chills are explored in this module. This module also covers basic riser and gating system terminology. By the end of this module, you will be able to describe the functions of risers; list the types of risers and their features; describe the function and features of a gating system; and describe the use of sleeves and chills. (0.1 CEU)

Risering Iron Castings

This module identifies the uniqueness of feeding graphitic cast iron alloys. The three ways that risers should be designed for cast iron are explained along with the factors that affect volume change. By the end of this module, you will be able to list unique riser considerations for iron castings. (0.1 CEU)
