tightly as the mold cavity may flex or distort. A cup or sprue is usually placed at the gate of the mold
as a receptacle for pouring or injecting the casting material.
Preparation and dispensing of the casting materials varies. Two-part urethanes are typically
packaged in cartridges and dispensed through a handheld pneumatic static mixer for smaller scale
applications. Automated meter mix dispense equipment is usually used by small production facilities.
The use of hand pumping static mix dispensers is not recommended, as they tend to produce off ratio
mixtures.
Placing the mold in pressure pot after material has been cast into it to minimize any bubbles present
is a common practice. This will reduce the effects trapped air will have on the final part.
Follow the cure cycle of the cast material before attempting to de-mold the cast part.
Conclusion
RTV molding is an extremely efficient method of generating multiple parts with thermoplastic
properties. There is no faster method of generating the master pattern than with a Z Corp. 3D
Printer, which will reduce the overall time it takes to get your final cast part. Whether a Z Corp. 3D
Printer is your complete prototyping solution or just a piece of it, there is no tool more valuable at
saving the things most valuable, your time and money.
