13. Molding¶
Overview¶
This weeks goal was to create a mold with out any production signs and use it to cast parts. I decided to use a 3D printed gear I created as the model that I will create the mold off of. I decided to work with my group mate Andrew Puky as he had create a slightly different but still similar gear. I decided to crate a soft mold using a silicone mixture of part A and Part B. This way I could create many hard casts that could be very useful for a future project.
Molding Process¶
I used Mold Star Series Platinum Silicone Rubber Part A and B with a 1 to 1 ratio to create the mold for this project.
a. We removed the Lids from both buckets and stirred the mixture thoroughly
b. I poured part A and part B into separate smaller red cups with the exact same volume
c. I hot glued my part down into a clean popcorn where I would later add both substances
d. I took each red cup and poured it into the popcorn bucket at the same time.
Casting Process¶
Next I used a hard resin as the casting material where I would pour it into my silicon mold of my gear
