A mold is a negative impression of the object you want to mold. Capture every detail of the object’s surface down to the smallest cut or gouge. It’s not just about inanimate objects either, it’s even possible to capture a negative of a living person breathing before using the body cast to reproduce an impressive life cast.
1. How to make a mold? – Mold making is an intricate art unto itself. There are many techniques such as block molds, blanket molds, glove molds, casting molds, and more. Manufacturing ranges from simple to intricate and some can be time consuming. Similarly, you can make the mold as a single piece or in two or more multiple parts depending on the shape and complexity of the object. The choice of the type of mold depends as much on the object as on your own skill and comfort level.
2. What do you need? – You have to stock up on various materials, supplies, tools, and equipment to make molds. There is a wide selection of materials for mold making, such as clay, plaster, alginate, moulage, polyurethane resin, latex rubber, silicone rubber, thermoset mold rubber, etc. Each of them has specific characteristics, functions and suitability. You will also need gloves, bowls, spatulas, mixer, brushes, knives, rasps, and sometimes even a vibrating table or vacuum chamber. You must source all your art supplies and tools from a reputable brand and supplier to ensure good quality and value.
3. How to do it? – Once you’ve decided on the most suitable mold making material and method, get started with actual mold making. You will need a mold box to hold the item and seal the item first. It is better to apply a release agent on the model. Then you need to apply or pour the mold-making material all over the object. Technical aspects such as openings and keys must be taken into account. The mold must set properly before carefully removing it from the object.
4. How to use the mold? – Once the mold has properly cured, it is ready for use. Clean and finish properly before emptying. You should carefully choose a complementary casting material, as the latter should not react or interfere with the mold in any way. This is followed by sealing and coating with a release agent before pouring the casting material.
5. Do you need help? – Mold making is interesting, enjoyable, and even becomes a lucrative profession. You can learn how to make a mold by learning from an expert, watching videos, reading how-to books, or even experimenting on your own. Or you can choose to join a workshop led by an experienced professional for valuable hands-on learning.
