8. Moulding and casting¶
This week I worked on defining my final project idea and started to getting used to the documentation process.
Task¶
Design a 3D mould around the stock and tooling that you’ll be using, mill it (rough cut + (at least) three-axis finish cut), and use it to cast parts.

Milling the wax¶
two sided tape is used on the undersid eof the wax to make sure it doesn’t move inside the machine
the milling pin should be adjusted to be right above th ewax and centereed in the middle

Moulding¶
the wax is cleaned and placed on a scale and the weight is zeroed to measure the amount of mold needed
the negative space is filled with water and measured.
the mold consists of two materials, a base and a hardener.
the amount measured before is split in half for the base and hardener of the mold. the amounts have been increased for incase more is needed.
the hardner is poured in the base and mixed then the mix is poured in the hardener cup to make sure the mixture is well combined together.
keep mixing for a full minute.
pour the mixture in the negative space, start from a corner and keep pouring slowly and steadily.
use a stick or a toothpick to pop the small bubbles and make sure the crevices are fully covered.
the finished mold had imprefections due to some temperature irregulations in the area it was stored in, and therefore, another will was made.
Moulding [second attempt]¶
water was filled in the negative space again.
the water was measured.
the weight of the base.
the weight of the hardener.
the base and hardener are mixed throughly from one cup to the other.
the mixture is poured in the negative space.
use a stick to pop the bubbles.
the mold after a few days.
