Applications and implications

Frequently Asked Questions and Answers

What will it do?

A small DIY Rotational Casting Machine. Compared to the centrifugal casting is distinguished by the use of liquid resins with respect to molten materials, rotational molding retrieves the handling mode of the mold.

Who's done what beforehand?

The machine is the scaled-down replay of molding machines in centrifugal casting and rotational molding. Compared to the centrifugal casting is distinguished by the use of liquid resins with respect to molten materials, rotational molding retrieves the handling mode of the mold. The process was applied to plastics in the 1940s but in the early years was little used because it was a slow process restricted to a small number of plastics. Over the past two decades, improvements in process control and developments with plastic powders have resulted in a significant increase in usage.

What materials and components will be required?

After a first prototype in wood, I thought of cambaire materials to realize my rotocaster, to make it more stable'll use aluminum profiles that are linked together with joints designed and printed in 3D. Other materials that will be used screws and bolts are tight to keep the molded parts in 3d.        Then I need to Plexiglas to create an empty corner where from time to time insert in weight to rotate the rotomolding, another Plexiglas will be used to create the central collector which contains the mold by spin.

Where will they come from?

The machine is designed to be played in two versions, a wooden version and a version in aluminum and aluminum, each I will have bought in the shops that are around my laboratory, and other material will be created using 3D printing.

How much will it cost?

The cost of the machine produced wood is around 50 €, the aluminum version Opinions more than less 100 €.

What parts and systems will be made?

Will be implemented for the joints hold together the rotacaster, the dials for changing speed of the machinery, the electronic board that will operate and turn off the machine, the parts cut by laser with Plexiglas to contain molds me three revolve.

What processes will be used?

Computer-aided design Computer-controlled machining 3D printing Molding and Casting Electronics design

What tasks need to be completed?

Fortunately I already tested the operation of my project, so I have the right size, and I started modeling the pieces to replicate later with the resin. Right now I need to concentrate on the implementation of the control board and the whole part about the power of the device.

What questions need to be answered?

It 'better to have two engines instead of one?
What is the best solution to fit the molds between the frames?
In the electronic control board is no need to insert different speeds?

What is the schedule?

This week will end 3D modeling, print and assemble the pieces to the aluminum structure.
Next week I will study the electronic and and power.
Then comes the time to assemble the project and operate it for operation.

How will it be evaluated?

projects can be separate or joint, but need to show individual mastery of all of the skills where possible, you should make rather than buy the parts of your project
