Foundry Moulds TRIZ Cases

A refractory netlike fabric spans the feeder opening to create a predetermined breaking point on the casting surface.

A flexible protective element absorbs compression forces on brittle feeder sleeves.

Pinene oxide and decene-1 oxide replace epoxy resin in binder systems to minimize residue buildup and improve pattern reusability.

A core sand filling method fluidizes granular material using aeration air before compressed air injection to fill the mold cavity.

A green sand mold applies a low-viscosity thermosetting resin to mating surfaces before heat-hardening to form a cured layer.

A mold locking device uses a gas pressure spring to maintain closing pressure between mold plates.

Single-operation low-pressure molding reproduces fine radial grooves within tight tolerances, avoiding pattern filling from paint layers.

Controlled water content in water glass coated foundry sand eliminates immediate use requirements while preserving casting quality.

Aluminum carriers embedded in sand web cores prevent breakage from molten metal pressure, enabling stable coolant channels between closely spaced cylinders.

Blending zircon aggregate with silica sand eliminates refractory coatings by suppressing thermal expansion and preventing veining.

Multi-path spot cooling eliminates spoke quality issues in large wheel hubs by integrating backwater management into the bottom mold.

Adjustable gas supply nozzles maintain constant distance to the mold during directional solidification, stabilizing cooling performance despite mold movement.

A shell mold support uses high thermal conductivity stucco to increase heat extraction rates during directional solidification.
