Plastic Injection Moulding for our new ‘Oyster’ GPS tracking device

I’m an electronics engineer yet I am often amazed at the work that our injection moulding partners do to get our ideas for a housing into reality. They start with a chunk of steel and then carve it out with CNC machines and various other techniques to create the 2 halves of the mould that is used to shape molten plastic into a housing.

Once the mould is complete they ‘inject’ the molten plastic into the mould where it cools (the steel often has water channels cut into it to help cool the steel). Once the the plastic hardens the two halves of the mould separate and the plastic piece is ejected.

Sounds simple enough, but the finer points take a lot of knowledge and experience to get right.

At the end of the day this is what we are after. The Oyster is an IP67 rated battery powered GPS tracking device that can send its data via Sigfox for the 1st version. We are also busy with designs for LoraWan, 2G/3G/4G cellular and possibly other communications.
