Metal Casting Simulation: Live Ingate Exit Velocity Tracking

June 23, 2010 - 2:44 am No Comments

Simulation of setup per Figure 6 from the paper entitled “A multiple-gate runner system for gravity casting”

I was curious to see the system in action; so modelled the exact geometry per figure 6. The paper was authored by:
Fu-Yuan Hsu, Mark R. Jolly, John Campbell

Ingate Velocity Graphs in order:
Scale:
Top: 3.5 m/s
Bottom: 0 m/s

Metal Casting Simulation: Feeder Design Analysis

May 19, 2010 - 2:34 pm No Comments

A simulation comparing the assigned feeder parameters per Table 2. design 16 of the paper entitled “Tapered Riser Design Optimization” by Creese/ Xia

Plate casting moduls = 2 in. (plate thickness/2)
Plate casting volume = 1024 in3
Cylindrical feeder volume = 679 in3
Tapered feeder volume = 525 in3

The simulations were performed using an 18Cr-8Ni stainless steel in resin bonded sand molds.

I have run several simulations using the design parameters per table 2 (all with stainless steel) and have found that in all situations the tapered top feeder performed inadequately.

Metal Casting Simulation: Recipe for Disaster “Textbook” 1-4-4 Ratio Based Fill System

April 23, 2010 - 6:28 pm No Comments

As a matter of comparison; here is a modelled “textbook” AFS 1-4-4 fill system.
The temperature colour gradient =
Top:1600C
Bottom:1550C
Alloy: 1026 Carbon Steel

DO NOT USE THESE ANTIQUATED, ARBITRARY METAL DELIVERY SYSTEMS. THEY ARE INADEQUATE AND CANNOT PRODUCE WORLD-CLASS CASTINGS.

Metal Casting Simulation: Disamatic Bearing Cap Fill, Vertically Parted Mold

April 14, 2010 - 6:08 pm No Comments

The waterfall action of the metal entering each cavity is a nightmare and needs to be eliminated. You are certain to find that the first “dribbles” of metal entering the cavity will end up as an “inclusion” in the casting. In all situations it is important to prevent the metal from free-falling.

Metal Casting Simulation – Vertically Parted Mold

April 11, 2010 - 3:33 pm 2 Comments

The fill and feed system for this 30 lb. stainless steel casting was simulated at Alloy Casting Industries in New Hamburg, Ontario Canada. The window on the left shows the temperature profile during the pour. Top of the scale is 1600F, bottom of the scale is 1500F.

The window on the top right shows the liquid fraction – liquid metal in the mold.

The window on the bottom right shows shrinkage porosity.

Metal Casting Technology: Naturally Pressurized Disamatic Fill System (alloy=gray iron)

March 21, 2010 - 4:43 pm No Comments

The use of some very specific design parameters can result in a beautifully balanced metal delivery system sure to produce great castings. Note: this design is iteration one and the precise balance is easily adjustable for the final production design. The pouring basin and feeder designs are not shown in this video. This simulation was performed at Alloy Casting Industries in New Hamburg, Ontario Canada.
