Injection Moulding Tool is Ready!


Original Post Date 19 June 2012


Finally, it looks as though the ModMyPi Raspberry Pi case is going into production! We've got a couple of minor tweaks to the mould, and final texture to add, but we're basically there. It's worth spending the time getting it right now so we're looking at starting production towards the end of the week. Thanks for sticking with us!


Now that's a lot of hardened steel! The mould block is formed from two pieces which are clamped together at a high pressure. Molten plastic is then injected into the mould at high pressure and rapidly cooled to create the part. 


Some pictures of the injection moulding mould:

A short video showing the injection moulding machine clamping the mould and creating the first T1 sample:



These T1 samples are from the first run of the mould. These samples are used to check the function of the case, making sure the two parts fit together well and the clipping function is stable. Function feedback for the T1's was good, there's a couple of small gaps which need to be tweaked out, there's some mild flash around the GPIO ports and LED holes, and the outside finish needs texturing and polishing, so we've got a couple of days more testing and tweaking but we're getting there!

Some pictures of the T1 Sample:

Exciting stuff! We're looking to get out all our back-orders by the end of the month. So check that letter box, as a case will be heading your way very soon :D

  3. Thanks for the update. Do you produce and ship directly from the UK? My 3D printed case does its job but can't wait to get my "real" deal :D

  6. Well done on the constant updates - even though I'm keen to get hold of the case, it makes the wait a little better :)

  9. Looking good, but I wish you didnt put "ModMyPi" on the case like that, wouldnt have minded on the inside or bottom, but on the top makes it look like the product is called "modmypi" when its really a rasbperrypi.

    1. I agree - the product name is too prominent

    2. +1 about the brand name. It just doesn't belong there. Maybe it could be placed on the inside or underneath if it's not too late. Aside from that, it looks cool.

    3. As much as we wanted to put 'Raspberry Pi' or the Raspberry Pi logo on the case, we are not affiliated with them. So it is out of respect of their trademark wishes that we have not put their brand name or their branding on the case.

      Sorry about that, it's a little too late to change as we don't want anyone waiting longer than they have to. Maybe we will change it in the future, and those first buyers will have the first edition ModMyPi branded cases. . . .

    4. I find it a perfect balance of their logo on the case, but still plenty of room for my own customization. Looks great, and looking forward to delivery of my Pi and the case! :)

  10. There's nothing to stop you putting a "Rasperry Pi Inside" logo on it, or even a custom version of Tux.

  11. Like Nike write 'foot inside' on their shoes? :)

    The case looks great, stop nitpicking or else they'll change their mind cause more delays!!

  12. Looks good and I like the name where it is

  13. It's been a week since the last update, any news? I am not in a great rush to get the case I ordered as my Raspberry Pi still has not arrived but it would be nice to have the case before the Pi arrives so I have something besides an old cigarette pack to put it in. :)

    1. Production was running yesterday and today, so distribution should start on Wednesday. I would estimate that you'll receive it next week at some point :)

  17. I am eagerly waiting for mine. One question remained open though. I saw it asked in other forums but there were no clear answers: what about ESD?

    1. I don't think there's ESD schielding since it's only a plastic case. Maybe painting it on the inside with copper paint is an option.

  21. The microinjection molding process is not just a scaling down of the conventional injection process; it requires a rethinking of each part of the process. Laser Welding

  24. Well explained, Mould is the main part of injection moulding process. Cavity helps to fill the plastic resin in the mould and help to eject the part.
