Process	Multicolour injection moulding
	Plastic parts with different separated colours or materials are produced using this process. The basic process is injection moulding. First one element of the part is moulded. A section of the tool is replaced leaving a new cavity and the next colour or component can be moulded embedding the first one. By using non-compatible plastic materials, flexible joints can be produced, e.g. arms and legs of a toy monkey.
