Foundry Moulds TRIZ Cases

A feeder insert pool collects excess liquid metal through a cover recess, preventing escape damage.

Independent vertical and horizontal drives position sand and steam supply heads, resolving die complexity trade-offs while shortening fabrication time.

Separate ceramic core pieces join via thermal deformation to produce intricate cooling channels.

Superimposing mold layers with dissolvable patterns and induction heating to create precise 3D metal castings.

A casting method controls temperature and plastic deformation energy to prevent recrystallized grain formation in metal workpieces.

A unitary neck-down feeder integrates a tapered base with predetermined fracture zones to detach cleanly from the body portion during casting.

A fluoride-free mold flux composition reduces inclusions and pollution while maintaining thermal stability.

A parallel linkage mechanism maintains storage unit posture during vessel rotation, ensuring feed port sealing without uncoupling.

Fastening recesses with additional cutouts capture excess adhesive, preventing defects on inner surfaces.

Lubricating die-release agent with solid particles protects inner surfaces of casting dies.

Thermoforming a plastic sheet forms a negative mould for metal casting, bypassing wax handling damage and burnout expansion issues.

A single-piece feeder body uses a segmented guide part to enable smooth telescoping movement in metal casting applications.

A molding apparatus uses a concavo-convex flow channel to guide gas from an annular cavity to a central discharge hole.

Specific sodium silicate and aluminosilicate ratios eliminate hazardous emissions while providing extended storage stability for foundry moulds.
