Insulation

Both Version 2 of the injection and extrusion machine are not insulated by default with the heating elements placed directly on the barrel without any coverage.

The machines work good but as you can imagine they have a few drawback:
1. they are less energy efficient as more heat exchange happens between the metal and cold air
2. they are more more sensitive to windy/cold
3. they are more dangerous people can inadvertently touch the hot heating elements

However, this is an easy fix. In this upgrade we will show you how to insulate the barrels using some insulation wool and a perforated sheet. This keeps the heating inside a thick case that reduces heat exchange between the heating elements and the air as we as preventing the hot metal to get in contact with human flesh :)
