The process of forming a material by forcing it, under pressure, from a heated cylinder through a sprue (runner, gate) into the cavity of a closed mold. Fittings are usually made by this process.

A step in the CD replication process where melted plastic is injected into a mold (which contains the 'stamper') under pressure, cooled and removed as a solid, clear plastic disc. The formation that was on the stamper has now been transferred to the plastic disc.

A process that involves transmitting melted resin into a mold's cavity; the molten resin then cools and solidifies, and the finished piece is ejected from the mold. (Modern Plastics Encyclopedia 1995). Glossary - L

Process of injecting melted materials into a mold.

A method of manufacture (typically involving wood heads and face inserts) in which the material (ABS, epoxy, graphite, etc.) comprising the head is heated to a liquid state and injected under pressure into a mold. When the material hardens, it takes the shape of the mold into which it was injected.

A manufacturing technique used during replication of compact discs. Molten plastic is injected into a mold and cooled to produce the disc. A stamper embeds the data pattern onto the disc surface as a part of this process.

The process of heating and melting polymer plastic and injecting it under pressure into a mold

The process used to inject molten polymer into a mold. Connector backshells are often injection molded.

The process of forming a material by forcing it from a heated cylinder, under pressure, through a sprue into a cavity of a confined mold.

In CD replication, it is the process where molten plastic (polycarbonate) is injected into the cavity of a mold under pressure, cooled and then removed as a solid clear plastic replicated disc.

A process for curing or molding parts by injection of rubber into a cavity.

Is the process where molten resin is forced through a gate into the space between the cavity and the core-pin.

A process in which melted plastic is forced into a relatively cool mold cavity which forms the plastic into the desired shape.

A molding process whereby a heat-softened polymer is injected from a Plastifier into a relatively cool cavity, which gives the article the desired shape.

A method frequently utilized in the manufacture of polyurethane screen segments. While this method is extremely cost effective when producing sizable quantities of a given aperture specification, the properties of the injection molded polymers (thermoplastics) do not offer the superior characteristics of "open cast" (thermoset) polyurethane's. (empty)(empty)

A molding procedure where heat softened plastic is forced into a relatively cool cavity, giving it the desired shape

The injection of a molten substance, usually metal, under substantial pressure into a mold.

The process for manufacturing plastic lenses whereby hot liquid plastic is injected into a lens mold of the desired shape and size.

Replication involving injection under pressure of molten plastic into the cavity of a mold followed by cooling and removal of the solidified part that retains a replica of the mold.

A process whereby molten material is forced through a gate, under conditions of heat and pressure, into a closed mold cavity.

A process by which a plasticized material is forced into a mold.

a process in which compound is heated in a separate device mounted on the mold, then forced to rapidly flow from there through passages (sprues and runners) into the mold cavity

The process used to form a shape by forcing a heated plastic, in a fluid state and under pressure, into the cavity of a closed mold.

Method of forming a plastic to the desired shape by forcibly injecting the polymer into the mold.

Injection molding is a repetitive process in which plastic is melted or plasticated and injected into a mold containing a cavity in the shape of the desired article. In thermoplastics, the mold is kept at a temperature below the solidifying point of the plastic, causing the injected polymer to “freeze,” thus forming the article. When processing thermosets, the material is kept below the temperature at which it would cause solidification due to its exothermic reaction until it enters the cavity. In turn, the cavity temperature is kept high to cause the melt to solidify.

Process in which molten metal or plastic is injected into the cavity of a carved die.

A molding procedure whereby a heat-softened plastic material is forced from a cylinder into a relatively cool cavity which gives the article the desired shape.

A method of forming articles (such as plastic) by heating the molding material until it can flow and injecting it into a mold

The most common method of making plastic models. Liquid polystyrene is injected into metal molds and allowed to cool, forming the parts. Most store-bought (i.e. non-specialty) models are made this way.

method of forming plastic to the desired shape by forcing heat-softened plastic into a relatively cool cavity where it rapidly solidifies (freezes).

A hydrostatic forming technique for shaping powders using plastic binders and relatively low temperatures and pressures.

Process of turning plastic resin into parts that range from very simple to highly complex in shape. The molten resin is fed under pressure into a mold where it solidifies into shape when it comes into contact with the cold wall of the mold and then is removed.

Manufacturing process where plastic is forced into a mold cavity under pressure.

Injection molding takes molten resin and squeezes it through a mold into a cavity which then producess a finished plastic part. See our page on the process of injection molding.

A molding process in which, under pressure, melted or liquefied plastic is forced from a cylinder into a cooled mold cavity to form a desired shape.

A process that utilizes melted plastics injected into steel or aluminum molds which ultimately result in finished production parts.

(extended definition) Method of forming objects from granular or powdered plastics, most often of the thermoplastic type, in which the material is fed from a hopper to a heated chamber in which it is softened, after which a ram or screw forces the material into a mold. Pressure is maintained until the mass has hardened sufficiently for removal from the mold. After the part cools and solidifies, the mold is opened and the part is ejected. No chemical reaction occurs during the molding process.

Method of forming a plastic to the desired shape by forcing the heat softened plastic into a relatively cool cavity under pressure.
