Abstract
A method of forming a thermoplastic article, comprises steps of a) positioning at least one preheated first component being hollow and having at least one open end in two co-operating first mould halves; b) extruding a blow-mouldable thermoplastic material into the first component and closing the mould halves; and c) blowing the blow-moldable thermoplastic material inside the mould halves to form an article on which the first component is fixedly engaged. The method is simple in implementation, low in cost and easy in modification, and by which a thermoplastic article of varied colors, patterns, materials, and/or functional components being fixedly mounted on its outer surface could be realized.

A method for forming a thermoplastic article of various colors, patterns, materials and/or components, comprising steps of:
- a) plastic moulding a first component being hollow and having at least one open end and heating the first component at a required temperature;
- b) positioning the first component in two co-operating first mould halves;
- c) positioning a blow head with a heated pre-blow plastic part in the first component inside the two co-operating first mould halves and closing them, and then making a stretch rod to contact inner mould bottom;
- and
- d) blowing the first component and pre-blow plastic part in the mould halves through the blow head to form an article on which the first component is fixedly engaged.

A method for forming a thermoplastic article of various colors, patterns, materials, and/or components, comprising steps of:
- a) plastic moulding a first component being hollow and having at least one open end into which a moulded pre-blow plastic part is inserted;
- b) heating the first component and the pre-blow plastic part at a required temperature and mounting them on a blow head;
- c) positioning the blow head with the first component and pre-blow plastic part in two co-operating first mould halves and closing them, and then making a stretch rod to contact inner mould bottom;
- and
- d) blowing the first component and pre-blow plastic part in the mould halves through the blow head to form an article on which the first component is fixedly engaged.
