Fully Open Source Manufacturing – Injection Molding of Wio Terminal

Hi our lovely seeeders, this is the first post of Open Source Manufacturing – Wio Terminal series. As we mentioned in the announcement of Wio Terminal, we will publicize every phrase of the development and introduce some basic knowledge of electronics manufacturing. By allowing people to follow us at each stage, including software updates and manufacturing, we hope to engage the community in a new era of development with increased practical knowledge and capabilities. Attention: It is fully open source!

“The biggest hustle on DIY is always enclosure.”, We have heard many customers complained about that. Laser cutting or 3D printing might be good choices, but it is oblivious that not everyone is capable of such complicated skills or has access to the equipment, not to mention the hardness of finding a cost-competitive custom service.

That’s why we especially design this compact enclosure for Wio Terminal to meet the needs of people who want to build a perfect physical interaction project with a well-designed and stylish case providing basic protection for your board.

Today we had a tour of the case manufacturing facility and were amazed by the manufacturing process. We made a vlog with detailed instructions on the injection molding of Wio Terminal. Let’ have a look!

There are also some pictures we would like to share with you. Let’s take a close look at the mold!

We made a few demo cases in order to test the mold. Wondering why the demo case is black while the pictures of the Wio Terminal you have seen before are white? During testing, the black color helps us find out any scratches or dents on the surface so that further adjustments could be made accordingly.

We welcome everyone to custom his/her own Wio Terminal and will be glad to share the case specs and 3D files of the enclosure later. Don’t be hesitated to contact us if you need more information for customization!

Stay tuned with us and let us know what you want to see in the next week’s post!
