0 a process used for making plastic objects, in which melted plastic is forced into metal shapes and left until it is hard -- 注塑成型法
The consequences of this include a dearer mould cost, longer injection moulding time and thus longer production runs.
Such systems occur in injection moulding processes for short fibre-reinforced composites.
The main operations are the injection moulding by means of a machine, the control of the quality of the product, and the packaging of the final product.
In the case of injection moulding we may be studying the forcing of molten polymer into a mould of a certain shape which is then let solidify.
The dispute referred to concerned only the injection moulding department of the factory in question.
The injection moulding process works better by flowing around high points rather than into pits on the metal surface.
In the early 1950s, as with many manufacturers, the company abandoned the use of lithographed tinplate for trains in favor of plastic injection moulding.
Injection moulding can be performed with a host of materials, including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.
