Moulding & Casting
Moulding is usually an intermediate step on the way to casting. The shape of an object, whether it is from nature, a sculpture, an object of daily use or, for example, the human body, is taken from the original, the master model, with the help of a material that is often liquid at first and then hardens and becomes elastic and dimensionally stable. In order to be able to cast without changing the mould, it is often necessary to build a support mould.
Through moulding and casting, objects can be developed, objects, sculptures, models, body parts or surface structures can be duplicated, moulds can be produced in larger numbers and objects can be translated into another material.
Which impression material and casting compound is best suited for which impression depends entirely on the nature of the project, but also on the working situation. Casting involves pouring a liquid mass into a previously made mould or casting form, which hardens due to different chemical processes.
The temperatures and the temperature of the mould or casting form can vary.
The temperatures and humidity in the workspace, for example, can strongly influence the setting time and curing behaviour of the individual materials. Silicones and synthetic resins are usually two-component systems that cure through a chemical reaction.> read more
