Additional Topics:
- How many slides are required to form the part?
- How is the surface finish created?
I have worked with a moulding and tooling company and will take a stab at this as well.
The first consideration will be the wall thickness of the cover and the ribs, I think the ribs need to be a third of the thickness of the wall of the part. There are some thumb rules for this. Doing this will avoid sink marks.
Second, we will ensure that we have a draft on all walls to ensure that the mold opens smoothly without the part getting stuck on the core or cavity
Next, we think about the parting lines, this looks straightforward we can use the edges around the part, and there will be one slider for the hole shown in the top view. There are also no ejection pin marks that are noticeable, maybe a stripper plate, blade ejectors or ejector sleeve is used. The gate point also is not clearly visible but having it on the B surface might be the way to go.
Coming to surface finish, the A surface will get a mirror finish on the mould, there are finishing standards (SPI-A/B) that are usually followed. The B surface can be left as an EDM finish or if the draft is very tight it can be polished to remove machining marks.
Let me know if there are any mistakes or if I have left out anything!
