Ooo! Ooo! Ooo!
I'm really excited about this project. I read an article in Model Engineers Workshop about this but dismissed it because of a lack of detail. Then I came across the book that the article was based on, Plastic Injection Molding Machine.
This is going to be such a cool project; it has everything!
- Metal cutting and welding to build the frame.
- Precision turning to make the injector mechanism, and the molds.
- High voltages and high temperatures, just to make it a little dangerous.
- A micro controller controlled electronic temperature controller - I can use more of the 8x5x5 LED displays. And do PID stuff.
- Sheet metal work to make the coverings.
Like most projects, it can be a pain to locate the core components. In this project it is the cartridge heaters and thermostat controller. After a bit of internet searching I discovered RS Components carry a range of cartridge heaters. They also sell industrial thermocouples. And they also have an affordable (to me) digital temperature controller (~$150), but this is only as a fallback as I plan to build my own, using a thermocouple and a ADS1240 A/D converter. There is an application note the shows how to read a thermocouple directly using the chip and a microcontroller.
Cool. I can't wait. But I'll have to finish the other projects first.
