Instructions | Working with the Medium Machinery Injection Molder

1

Step 1

Packages had been severely 'munged' during shipping, but nearly everything survived, a testament to the machine! The acrylic "Guard" had broken... I wish I didn't fix it, cause it just gets in the way

Step 3

Additions to the Machine:
I penciled in the line-up point of my mold, to the faceplate of the bottom bracket. I may make a laser cut tool for it later.
I created a set of rulers on the side of the machine to gauge the shot size/volume/weights that I will be using...

Step 4

Assembling the Machine:
Be sure to follow the directions carefully... also make sure you insert ALL the wires into their ports...

Step 5

Awesome, thanks for the write up. Can you provide more information on making a mold and the resulting plastic part quality?
