Operation consisting in cutting and assembling materials.
The injection press is used to produce objects in very large quantity, extremely fast. This technique can produce finished, complex parts in one single operation, within a weight range of a few grams to several kilograms. The material is injected under pressure from a heated cylinder via a nozzle (channel, inlet), into the cavity of a closed mould.
Process via which heated or non-heated plastic is forced through a die in order to form long, continuous parts such as tubes, pipes or semi-finished products like formed sections or strips.
Consists in pressing the material directly into the recess of a hot mould.
Process for forming metal sheets or other thermoplastic sections, generally heated on a simple geometrical mould and then subjected to a cooling operation. This technique is used to produce all sorts of hollow objects.
Rotational moulding process designed to produce hollow sections of all dimensions. The mould, which is partially filled, spins around one or more axes, at a relatively slow speed, until the load is distributed, by gravity, against the wall of the mould and is solidified by appropriate means.
Assembly of parts surrounding a hollow cavity from which the moulded material takes its shape.
