Foundry Moulds TRIZ Cases

Steel composition with controlled Ti-containing oxides balances fracture toughness across welded metal, heat-affected zone, and base metal.

Segmented runner branches with distributed gates mix melt flows to prevent blowholes and hot cracks in complex AlCu castings.

Segmented cooler assembly isolates from tank vibrations to prevent fatigue cracks and sand infiltration.

Exterior cavities in the riser sleeve create air gaps that insulate molten metal, preventing premature solidification and shrinkage defects during casting.

Merging pivot pin and kidney cores into one unit stabilizes the mold, while a single solid rib replaces thin ribs to ensure consistent wall thickness.

An adhesive bonding layer between the ceramic article and fixture prevents surface chipping while ensuring high repeatability in positioning accuracy.

A ratchet wrench body uses a horizontal slot chamber and plug to maintain structural strength while enabling uniform force exertion.

Segmented cope and drag mold halves eliminate draft angle requirements, resolving dimensional inconsistency while maintaining flat surface finishes.

Gas vents with permeable covers channel hot gas through thin-walled molds, resolving temperature uniformity issues in investment casting.

A disposable ceramic mold surrounds a leachable core body to form an internal cavity for precise ceramic core deposition.

Casting liquid over magnetic fluid templates creates high aspect ratio structures, avoiding expensive lithographic equipment costs.

Graft polymerization bonds hydrophobic polymers to cellulose nanofibers, preventing hydrogen bond aggregation and enabling dry pellet handling.

Compensating for manufacturing defects by recalibrating core positions through 3D scanning, ensuring uniform wall thickness in turbine blades.

Inclined groove walls in the casting mold prevent undercut formation and allow demolding up to 90 degrees parallel to the surface texture.

Fluid ablation decomposes aggregate molds to enable direct metal cooling, resolving slow heat extraction and porosity in aluminum casting.

An expansion portion widens downward to guide molten metal flow, forming a weak junction that absorbs stress and prevents airbag module deformation.

A flexible elastomeric mold captures complex ceramic cores for gas turbine blade production.

Yellow iron oxide additives suppress smoke generation from decomposing organic binders while maintaining tensile strength and extending work time.

Interference fit holding device secures casting cores in molds, eliminating holes and reducing finishing work.
