The two sides fit together to produce a mould cavity.

A mould cavity is essentially a negative of the part being produced.

It is used in the process of sand casting for preparing the mould cavity.

After cooling, the solid metal surface has the shape of the mould cavity.

Essentially the mould cavity is the negative of the plastic component being moulded.

The laser-operated process can be used to create mould cavities or finished components.

A blend of hard metal powders is then packed inside the mould cavity, together with a steel core.

The moulds are baked and molten metal is poured into the mould cavity.

In addition, devices for ejecting the part from the mould cavity are usually attached to the moveable platen.

The upper mould is installed and vacuum is applied to the mould cavity.

The cycle begins when the mould closes, followed by the injection of the polymer into the mould cavity.

Most metal processing operations require the mould cavity to be preheated prior to placement of the metal.

The lost-wax process can be used with any material that can burn, melt, or evaporate to leave a mould cavity.

Despite this, the reaction mixture must enter the mould cavity in a laminar flow, not in a turbulent condition.

Aided by a built-in injection system, the operator removes the finished cushion from the mould cavity where it has been allowed to fully expand.

Cold shuts occur when two fronts of liquid metal do not fuse properly in the mould cavity, leaving a weak spot.

For mass production, the model within ArtCAM is mirrored to produce a mould cavity surface.

Injection moulding is a manufacturing process whereby a measured amount of heated, molten plastic is forced under pressure into a mould cavity.

The new injection blow moulding (or injection vacuum forming) technique involves changing the mould cavity around a moulded preform, which remains on the core.

The system establishes a 'fingerprint' reference curve of the mould cavity pressure which describes the optimum process and therefore the optimum quality of the moulding.

Resin transfer moulding includes numerous varieties which differ in the mechanics of how the resin is introduced to the reinforcement in the mould cavity.

FLASH The excess material on a rubber part resulting from rubber being forced out of the mould cavity during the moulding operation.

The matrix material can be introduced to the reinforcement before or after the reinforcement material is placed into the mould cavity or onto the mould surface.

In compression molding, a "preform" or "charge", of SMC, BMC is placed into mould cavity.

This requires the mold cavity size to be smaller than the final part.

Here, the metal is introduced under slight pressure into the closed mold cavity.

The pattern is lifted from the sand, leaving a molding cavity.

Then the pattern is removed along with the channel plug, leaving the mold cavity.

Another possible cause is back pressure from improperly vented mold cavities.

They are also not needed for casting processes that utilized pressure to fill the mold cavity.

The dies are prepared by spraying the mold cavity with lubricant.

Plastic work tray with molded cavities for glass substrate and tools.

With both methods, the sand mixture is packed around a pattern, forming a mold cavity.

Pattern: An approximate duplicate of the final casting used to form the mold cavity.

Gates: The controlled entrances from the runners into the mold cavities.

The connection of the riser to the molding cavity can be an issue for side risers.

This can be overcome by designing the mold cavity to slope the leg inward to begin with.

The casting liquid (typically molten metal) is then poured into the mold cavity.

Once the mold cavity is filled, the pressure is maintained until the casting solidifies.

Finally, any cores are automatically set into the mold cavity while the next mold is being prepared.

Molding flash can be caused from old or worn mold cavities that no longer fit tightly together.

Internal chills are pieces of metal that are placed inside the molding cavity.

It is also used as a mold wash (a coating applied to the molding cavity) to improve surface finish.

All clay is carefully removed and the prosthetic material is cast into the mold cavity.

The metal will flow down the sprue, into the mold cavity, and back up the riser (of which there may be several).

Mold cavity: The combined open area of the molding material and core, where the metal is poured to produce the casting.

The geometrical shape of the mold cavity has direct effect on progressive and directional solidification.

Fill the mold cavity with molten metal.
