Foundry Moulds TRIZ Cases
- Foamed Aluminum Special-Shaped Parts via Disposable Ceramic Shell Casting
Disposable ceramic shells eliminate metal mold wear during foamed aluminum casting, resolving the trade-off between process simplicity and tooling durability.
- Copper Alloy for Lost-Wax Casting Without Heat Treatment
Aluminum-manganese alloy formulation eliminates heat treatment steps, resolving toxicity risks from beryllium and cobalt while maintaining mechanical strength.
- Zircon-Silica Foundry Sand Blend for Casting
Blending zircon aggregate with silica sand reduces veining defects and improves dimensional accuracy by lowering the cristobalite phase transition temperature.
- Monoblock Aluminum Caliper Housing Manufacturing
A monoblock aluminum caliper housing manufacturing method uses a salt-coated middle core to facilitate easy removal and thorough cleaning.
- Foundry Core Deformation Method for Complex Geometries
Heated foundry cores undergo external deformation to form complex undercuts and helix shapes without multi-part core boxes.
- Coupler Knuckle Core Segmentation for Fatigue Resistance
Segmented core assembly creates internal cavities within coupler knuckles to manage force transmission.
- Mold Surface Treatment via Inclined Sliding Abrasive Blasting
Inclined sliding abrasives flatten mold surface peaks, preventing load concentration and rapid wear during demolding.
- Saltcore Composition for Aluminum Die-Casting Shrinkage Control
Composite saltcore with K+, Na+, and Mg2+ cations reduces shrinkage to less than 1.2% while maintaining strength above 15 MPa.
