Plastics processing is the set of techniques used by the plastics industry for the transformation of plastic materials (polymers). The term is derived from the word "plastic", associated with the suffix "-urgie" (from the Greek -ourgos, from ergon: work, production): literally, plastics is the work of plastic.
3d printing
noun
3D printing or additive manufacturing brings together the manufacturing processes that make it possible to create parts in volume by adding material in successive layers
fr: impression 3D
composite
noun
The composite material is an assembly of at least two immiscible materials (but having a high adhesion capacity)
fr: Composite
Compression molding
adjective
Compression molding is a method of shaping by molding parts made of plastic or composite materials. These materials can be based on thermoplastics and especially thermosets.
fr: Moulage par compression
extrusion
Noun
Definition of plastic extrusion Plastic extrusion is a thermomechanical industrial process of continuous transformation. It makes it possible, in fact, to transform the raw material, like plastic, with a machine called an extruder into a long or flat profiled product.
fr: extrusion
Feed hopper
noun
A feed hopper also called a buffer or feed hopper conveyor, allows the intermediate storage of a product to generate a controlled flow or to ensure batch production or recycling
fr: Trémie d'alimentation
injection
Noun
Plastic injection is a forming process using moulds. A material, such as synthetic resin (plastic), is heated and melted, then transferred to a mold where it is cooled to the desired shape.
fr: injection
mold
noun
The mold is an essential element in the manufacture of finished objects by plastic injection. Also called tooling, it is what allows the plastic to be shaped to give it its final shape. A tool can weigh from a few hundred kg to several tons, and is made up of a frame and cavities.
fr: Moule
mold closing
noun
fermeture du moule ; verrouillage du moule (la force de verrouillage permet de maintenir le moule fermé pendant l'injection) ; dosage : la matière est acheminée à l'avant de la vis de plastification (par rotation de la vis), donnant ainsi une réserve de matière prête à être injectée ;
fr: fermeture du moule
mold cooling
adjective
The plastic is injected into the injection mold, and the heat is transferred to the injection mold to be cooled; ②The plastic in the mold cavity is in close contact with the mold cavity and will not be separated due to cooling shrinkage
fr: Refroidissement du moule
plastic dosing
noun
The weight feeder or gravimetric feeder is used to dose and then mix plastic raw materials in the form of granules, grains or powder
fr: dosage plastique
Polyamide
noun
Polyamide is a chemical plastic material which by its weaving has many properties. Polyamide has the ability to absorb moisture, to dry quickly, to be almost dimensionally stable, to be able to stretch and to be very resistant.
fr: Polyamide
polyester
noun
polyester is a polymer primarily composed of compounds within the ester functional group. Most synthetic and some plant-based polyester fibers are made from ethylene, which is a constituent of petroleum that can also be derived from other sources.
fr: polyester
polymer
noun
Organic or mineral macromolecular compound resulting from the combination of several molecules from a single monomer or from different monomers.
fr: polymere
polymerization
noun
Polymerization is a process through which a large number of monomer molecules react together to form a polymer
fr: polymerisation
pultrusion
noun
Pultrusion is a composite synthesis process where a constant cross-section and production rate is obtained. In this process the fibers are pulled through a heated die. While passing through the die, a constant pressure is applied, resulting in the resin melting and its impregnation into the fibrous reinforcement.
fr: pultrusion
recycling
noun
Recycling is the recovery of plastics (in the form of polymer, monomer or chemical building blocks) in such a way that they replace raw or primary materials used as chemical building blocks in the production of plastics and plastic products and packaging. plastic
fr: Recyclage
rotomolding
noun
otational molding is a technique that uses plastic powders. The main successive stages of rotational molding are as follows: coloring of the plastic powder by adding dyes and dosing of the colored material (according to the final weight desired for the part)
fr: rotomoulage
Thermoforming
noun
Thermoforming: definition. Thermoforming is a manufacturing technique that consists of taking a plastic material in the form of a plate or coil, heating it to soften it and then taking advantage of its deformation capacity to shape it using a mould.
fr: Thermoformage
thermoplastic
adjective
A thermoplastic material is a material having the property of softening (sometimes a frank melting is observed) when it is heated sufficiently, but which, cooling down, becomes hard again.
fr: thermoplastique
thermosetting
adjective
thermosetting (technical) which hardens irreversibly above a certain temperature (for a plastic material).
