Generally to build composite molds to build parts out of you need a plug.  Plugs can be from a variety of materials. In this demo we’ll show you some examples and go over what to look for in a good plug. Then we’ll dive into mold making techniques and types of molds for different production processes.

April 16th- Vacuum Infusion. In this demo we’ll introduce you to vacuum infusion, a closed mold process where the reinforcements are placed in the mold or on the part dry and then resin is introduced using the difference in atomspheric pressure.  This is a neat way to build parts and can provide better laminates than open molding methods.  We’ll build some parts and show you how to set up test panels for switching your parts over to resin infusion.
