=====Making a Resin Mold for the Injection Molder=====
The Mold:
* Find/make a 3D model of the object you want to mold.
* Follow the instructions in the linked video to turn the object into a 3d model on SolidWorks:
{{#evu:https://youtu.be/jm9b_8kYKuQ}}
* Save the SolidWorks file as an STL file.
* Then follow the steps in the maker-hub wiki to print this STL file on the Formlabs resin 3D printer. Make sure to use the HIGH TEMP RESIN in the Formlabs and not another type of resin as this kind is the best for injection molding.
** TIP: Curve the edges of the mold to better fit inside the mold casing
The Aluminum Casing (x2):
* Find a piece of aluminum stock that is larger than one-half of your mold in every dimension.
* Next, cut down the piece using the mill until the aluminum block is somewhere between 1/8”-1/4” larger than the piece of your mold. This will allow a wall of that thickness around your mold.
* Then mill out a cavity in the block of aluminum that is around the size of your mold. This cavity will be for press fitting half of the mold into, but it shouldn’t be too tight or else the mold might break. The depth of this cavity should be the same distance as the thickness of the mold piece, so when press fitted the casing and mold faces are flush.
* Then, drill out a hole at the top of the mold for the spout where the plastic will be injected into.
* The printed mold will then be press fitted into the cavity but be careful not to crack the mold when press fitting.
