A brief review on the history and present of mold making techniques
Molding has been a very old form of making sculptors. Liquid raw materials are filled in a mold frame and after drying they were polished and painted to give the final structure. Molding traditionally has been done using china clay, Plaster of Paris and clay mixed with various chemicals to some extent as well. For a successful sculpture the mould itself has to be sculpted in detail. It is basically a hollow block which is filled with the liquid material with which the sculpture is to be made of. Materials used to fill in the block are either, plastic, glass or metal or can even be some ceramic raw material. Once the liquid inside the mold gets hardened it takes the final shape of the subject.
Normally the common process of molding uses a two mold process where it is proportionately cut in between two half’s. For more larger and valuable objects, piece molds are used where a number of different molds are used and this is considered to be a complicated process. The substance which is used to release the hardened subject from the mold is called the release agent. Moulded plastics are typically used for furniture, household goods, and other structured materials. There are various types of molding which are used worldwide and they can be blow molding, compression molding, foam molding, injection molding, matrix molding, plastic molding, transfer molding and extrusion molding.
These days’ cheap tactics are also very much in trend, where the raw material can be sourced from local market and you can prepare your own substance with the cheap mold making process. The substances which you want to make at home through these cheap molding techniques are very well explained all over the internet. Like for example these days silicon molding ways and techniques are explained all through the internet and the process explains in detail how one can shop for the materials required through local market and can make their own attractive moulds at home. They can be of various sizes and shape and you can run your own imagination all through it also. There are various companies working on these molding methods and they have incurred good amount of expenses in infrastructure and equipments to develop machines which can exactly work on the cheap molding practices but can deliver high class results. China is one country where these techniques are used in wide ways. The types of molding explained above, are all used in their manufacturing process but are done with very advanced tooling services. The cost factor is also very limited but the output is absolutely extraordinary. The quality is also very much international and the delivery time is less too. The companies are professional in plastic injection molding, rapid prototype mold making as china mold makers.
