1. Former Design Draft Angle Flat sides Rounded Corners
2 matching formers can be made so that a 2 part casing can be formed in 3 halves.
Rounded Corners
There must be enough room for the PCB, Battery holder, inputs and outputs within the casing
Ventilation hole drilled to enable all spaces to be formed correctly
Vacuum Former Design – Key Points
Draft angle: To enable the former to removed from the casing
Flat sides on the bottom mm: To enable the base/other half to be slotted in securely
Rounded Edges: to prevent weak points and cracks in the casing caused by sharp edges on the former
Ventilation holes: to enable any spaces or holes to be formed correctly by allowing the air to be sucked out
NB: The bottom of each former should be left sharp and not rounded or else the former will be stuck in the casing.
