From A Two-Piece Silicone Mold! Part 2

It’s easy to make clean resin castings when you have a perfect silicone rubber mold. This video is part 2 of this earlier video:    • Silicone Mold Making: When To Use A Two-Pi...   SKIP AHEAD TO THE GOOD PARTS: 00:00 Casting a resin part in a 2-part silicone rubber mold. 00:21 Orienting the mold in space so that it will fill properly. 00:58 Why not inject the resin into the mold? 03:12 Trimming the mold to avoid slight deformation by the mold case. 04:19 Building the mold cradle. 06:22 Cutting the cradle parts on the tablesaw. 08:32 Some bandsaw cuts and assembling the cradle. 10:21 Fitting the rubber bands. 11:50 Trimming the rubber mold so that it fits easily into the pressure pot. 14:55 How much resin will I need to make the casting? Weighing the model. 16:00 Weighing out the urethane resin. Mixing the A and B sides. 18:21 Pouring the resin into the mold. 18:53 Dropping the mold into the pressure pot. 19:55 Taking the mold out of the tank. A little bit spilled but it’s OK. 21:00 Remember, you can check your witness cup to see if the resin is cured. 21:13 Time to open the mold. 21:57 A slight problem: I failed to cut completely through the rubber bridge in the spout. 23:00 Problem solved; the casting comes out and it’s perfect! 24:29 Trimming the sprue and vent on the bandsaw. 25:14 It’s easy if you trim your sprues immediately after the parties demolded. 25:53 Very little flash for a 2-piece mold. Super clean parting lines! 26:15 Great result, I couldn’t be happier! Thanks for watching!
