A mold is a negative impression of the object you want to cast. Capture all the details of the surface of the object to the smallest scour or indentation. Nor are they only inanimate objects: it is even possible to capture a negative of a living person who breathes before using the body mold to reproduce a surprising life model.
1. How to make a mold? – The manufacture of molds is an intricate art in itself. There are many techniques, such as block molds, blanket molds, glove molds, pouring molds and more. Manufacturing varies from simple to intricate and some can take a long time. Similarly, you can make the mold as a single piece or in two or more multiple pieces depending on the shape and complexity of the object. The choice of type of mold depends both on the object and on your own dexterity and level of comfort.
2. What do you need? – You have to stock up on various materials, supplies, tools and equipment to make molds. There is a varied selection of materials for the manufacture of molds, such as clay, gypsum, alginate, moulage, polyurethane resin, latex rubber, silicone rubber, thermosetting mold rubber, etc. Each one of them has specific characteristics, functions and convenience. You will also need gloves, containers, spatulas, blenders, brushes, knives, scrapers and, sometimes, even a vibrating table or a vacuum chamber. You must obtain all your materials and art tools from a trusted brand and supplier to ensure good quality and value.
3. How to do it? – Once you have chosen the most suitable material and mold making method, start with the actual mold making. You will need a box of molds to contain the object and seal it first. It is better to apply a release agent on the model. Then you have to apply or pour the mold making material throughout the object. Technical aspects such as spikes and keys will have to be considered. The mold must be placed correctly before unmolding it carefully from the object.
4. How to use the mold? – Once the mold has been properly cured, it is ready for use. Clean and finish properly before casting. You must carefully choose a complementary casting material, since the latter should not react or interfere with the mold in any way. Sealing and coating with release agent follow again before pouring the casting material.
5. If you need help? – The manufacture of molds is interesting, pleasant and even makes it a profitable profession. You can learn to make a mold by learning with an expert, watching videos, reading instruction books or even experimenting on your own. Or you can choose to join a workshop led by an experienced professional to obtain valuable hands-on learning.
