Mold Making Review | How To.. Contents | ||||||||
 We have covered a lot of information
about mold making and casting, but have offered relatively few of
the many techniques available for making molds and castings.1. The first rule of mold making: You will make mistakes. Be patient with yourself and be willing to learn. Professional mold makers will tell you that they did not learn moldmaking overnight and are still refining their craft. Also, you can call on us anytime for assistance. 2. Remember, there are different ways to make a mold of any original model. Study your model and develop a strategy or “plan of attack” for applying the mold rubber and support shell (if necessary). Design the support shell so that it does not mechanically lock on to the model. “Map out” the sections of the support shell to avoid potential problems. 3. Read the technical bulletin for each product that you are using. Know the mix ratio, working time, demold time, etc. for the rubber or plastic product you are using. 4. Use only recommended release agents and sealers for mold making and casting. 5. Mix thoroughly, not fast--scrape sides and bottom of the mixing container several times before applying rubber or plastic.
