Online hot sale automotive parts custom car parts injection moulding

Injection moulding uses a ram or screw-type plunger to force molten plastic or rubber material into a mould

cavity; this solidifies into a shape that has conformed to the contour of the mould. It is most commonly used

to process both thermoplastic and thermosetting polymers, with the volume used of the former being

considerably higher.Thermoplastics are prevalent due to characteristics that make them highly suitable for

injection moulding, such as ease of recycling, versatility for a wide variety of applications,and ability to soften

and flow on heating. Thermoplastics also have an element of safety over thermosets; if a thermosetting

polymer is not ejected from the injection barrel in a timely manner, chemical crosslinking may occur causing

the screw and check valves to seize and potentially damaging the injection moulding machine.

Injection moulding consists of the high pressure injection of the raw material into a mould, which shapes the

polymer into the desired form. Moulds can be of a single cavity or multiple cavities. In multiple cavity moulds,

each cavity can be identical and form the same parts or can be unique and form multiple different geometries

during a single cycle. Moulds are generally made from tool steels, but stainless steels and aluminium moulds

are suitable for certain applications. Aluminium moulds are typically ill-suited for high volume production or

parts with narrow dimensional tolerances, as they have inferior mechanical properties and are more prone to

wear, damage, and deformation during the injection and clamping cycles; however, aluminium moulds are

cost-effective in low-volume applications, as mould fabrication costs and time are considerably reduced. Many

steel moulds are designed to process well over a million parts during their lifetime and can cost hundreds of

thousands of dollars to fabricate.

Applications

Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts

and components, toys, pocket combs, some musical instruments (and parts of them), one-piece chairs and

small tables, storage containers, mechanical parts (including gears), and most other plastic products available

today. Injection moulding is the most common modern method of manufacturing plastic parts; it is ideal for

producing high volumes of the same object.
