Draft analysis testing

To ensure the components of the product can be created using industrial standard moulding methods a number of test needs to be carried out on the components. The first of these tests is a draft analysis, this tests ensures the components can be de-moulded easily. The draft analysis works by using colour indicators showing draft from negative to positive, this indicator can be found at the bottom right of each image.

Console front
Outside

To ensure this component can be de-moulded the outer face needs to have a positive draft. The original draft analysis presented several issues shown in red and blue. Also the lip that secures the cover will not allow de-moulding. The altered draft analysis shows the added draft to the inner wall, PCB supports and outside of the arms shown in orange. Also the lip was removed and stilts were added.
aInside
To ensure this component can be de-moulded the inner face needs to have a negative draft. The original draft analysis presented issues shown in yellow and red. The second draft analysis shown on the right shows the added draft to the internal support struts and port support shown in purple.
bConsole back
Outside
To ensure this component can be removed the outer face needs to have a negative draft. The original draft analysis presented issues shown in red. The second draft analysis shown on the right shows the added draft to the screw guides, air vent holes and port holes shown in purple
c
Inside
To ensure this component can be removed the inner face needs to have a positive draft. The original draft analysis presented several issues shown in red. The second draft analysis shown on the right shows the added draft to the support structures, screw holes and port support shown in orange/yellow. The air vent holes that show up in red here are due to them being drafted on the console back outside so the air vent will need to be accounted for by solely the back mould.

dConsole fingers
To ensure this component can be de-moulded the inside of the component shown on the left need to have a negative draft and the outside of the component shown on the right needs to have a positive draft.
eConsole hand inserts
To ensure this component can be de-moulded the top of the component shown on the left needs to have a positive draft and the bottom of the component shown on the right needs to have a negative draft.
fConsole feet
To ensure this component can be de-moulded the top of the component shown on the left needs to have a positive draft and the bottom of the component shown on the right needs to have a negative draft.
gConsole supporting bracket
To ensure this component can be de-moulded the shelf of the bracket needs to have a negative  draft. According to the first draft analysis on the left this is not the case. The second draft analysis on the right shows the bracket shelf with an added draft. A draft has also been added to the outer side to ensure easy de-moulding.
hCollectable RFID characters body
Due to the shapes of these components and the method of manufacture proposed they all need to have a positive front draft and a negative back draft. The images below show that the colletable small charcters have the correct draft for de-moulding

iCollectable RFID characters feet
To ensure this component can be de-moulded the top of the component shown on the left needs to have a positive draft and the bottom of the component shown on the right needs to have a negative draft. The orange sections are thin so a draft was applied here to ensure that during de-moulding the part would not break.
j
Collectable RFID characters belly piece
Due to the shapes of these components and the method of manufacture proposed they all need to have a positive front draft and a negative back draft. Due to the fit between the body and the beely piece these components cannot have the sides drafted for de-moulding therefore they will possibly need to be removed with the use of compressed air. The images below show that the colletable small charcters belly piece have the correct draft for de-moulding.
kWrist band controller
As both the adult and child wrist band controller are the same shape they were drafted together. To ensure this component can be de-moulded the top of the components shown on the left need to have a positive draft and the bottom of the components shown on the right need to have a negative draft. The internal section draft will have the solid components already inserted during moulding therefore will not cause any issues during de-moulding.
lWrist band controller technology housing
To ensure these components can be de-moulded the top component shown on the left needs to have a negative draft on the outside face and a positive draft on the inside face. The bottom components shown on the left needs to have a positive draft on the outer face and a negative draft on the inside.

The original image shows the draft state of the component, if the component is not suitable for de-moulding the altered image shows the changes made in order to ensure that the component can be successfully de-moulded. If the component does not need any changes then the component draft analysis is shown. Throughout this process it has been ensured that all components can be de-moulded and ensures that manufacture of both the components and moulds themselves will be efficient. The next stage is to explore the production, process and material selection for both the components and the components moulds.
