The simple art of mold making takes a complicated twist when complex models and multi-part molds enter the picture. But help is always at hand that will enable you to master this technique as well.

Making a mold is quite a simple and straightforward process. All you have to do is coat the model with the mold making material to capture a negative impression of the same. Depending on the model and technique, you can even brush or pour the material to form a mold.

How to make Molds

How to make molds does require care and caution over the technical details like making a mold box, applying a release agent, avoiding air bubbles, creating a shell mold (if needed), allowing proper set and cure, etc. Yet, the block and blanket molds can still be made quickly and easily as long as the model is simple or has a flat base on one side.

Things get more complicated when the model turns complex – like a statuette that has crevices and undercuts on all sides. A mold obviously cannot capture the entire shape and details in one go itself.

And there lies the answer to every novice moldmaker’s predicament. The solution is to make the mold in parts – two or even more depending on the intricacy of the model.

Two part molds open the door to a whole new set of complications in their making. It is not limited to just make a parting line to delineate which part of the mold you are covering first and what will be remaining. You even have to work out how the mold parts will fit together later to form a complete mold. This requires making spues on the different parts that make it easier to match them up.

However, you needn’t stress yourself out over the elaborate and intricate steps of two part molds.
