Moulding and Casting

• Group assignment

  • Review the safety data sheets for each of your molding and casting materials
  • Make and compare test casts with each of them

• Individual assignment

  • Design a 3D mould around the stock and tooling that you'll be using, mill it (rough cut + (at least) three-axis finish cut), and use it to cast parts.

I decided to make an umbrella handle(final project) on Moulding and Casting Week.

When molding and casting, we should know that the work is done in positive, negative, and positive order.







Create a Positive Mold Model

I decided to use Fusion360 to make the Positive Mold Model.

First, I measured the size of wax to be used in the Positive Mold Model.











Based on the measured wax size, the frame was made and the handle design was added.











I made hole for the material and air hole.







made a sphere that could hold the frame and made a mold design on the opposite side.











The simulation and tool pass were set using the manufacture function in Fusion360.







Use setup function to set the x,y,x axis and stock.



















Axis position is set by the stock point function.















stock size is set to the size of the wax used







The adaptive cleaning function was used to set the end mill and cut.







The size of the end mill to be used was measured and a new end mill setting was created.



















finished setting and did simulation.

In the simulation, we found a problem of ignoring the handle and proceeding with the cutting.







The model that was ignored in the simulation was selected in setup and the problem was solved.
