Real moulds, real specifications.

Slider and ejector-plate structure

A large base-station shell with undercuts on several faces. Sliders release the side features, and a dedicated ejector-plate layout pushes the deep shell evenly off the core.

Designed for Volkswagen

A ribbed frame with openings and clips on every side. Sliders on several faces, some driven by hydraulic cylinders, form the side openings and clips.

A round part with an internal thread. A motor drives a gear train that rotates the threaded core, so the thread is released without stripping.

A tall, curved panel with long openings. The mould has to keep a long cosmetic surface smooth and evenly cooled from end to end.

A spiral feature sits inside a side slider. A rifle bar (a helical screw) turns the core as the slider moves, so the spiral unwinds instead of being torn off.

Slider with motor-driven unscrewing

The internal thread sits on a side feature, so the unscrewing core rides inside a slider. A motor turns the core out of the thread before the slider retracts.

A filler housing with a deep funnel and clips around its edge. Several sliders work around the funnel to release the undercuts on each side.

A curved pipe cannot be cored with a straight pull. An arc core-pull swings the core out along the radius of the bend.

A curved, narrow front bumper with a window for the sensor. The parting line and sliders follow the arc so the visible face stays clean.

Six rear-mould stations sit on one rotary table, which indexes the parts from station to station during the moulding sequence.

Reverse (inverted) mould

In an inverted mould the core and cavity sides are swapped and ejection works from the fixed half. This keeps gates and ejector marks off the cosmetic face.

Angled teeth lock the gear into the cavity, so it cannot be pushed straight out. The gear is released with a rotating motion that follows the helix angle.

A long base chassis with ribs, bosses and mounting features. Sliders release the side openings while ejection is balanced along the full length.

A deep, double-curved shell with vents and openings on several sides. Large sliders form the side openings and are laid out to protect the visible outer surface.

A large crate with ventilated walls on all four sides. Sliders on each side form the vent pattern, and the core cooling helps the deep box release square.

A deep, thin-walled round container. The mould is laid out so the long core cools evenly and the bucket releases cleanly from the deep draw.

An open mesh basket with tapered walls. Sliders on each side form the mesh walls, and the cooling layout helps the long, thin ribs fill evenly.
