How Are Nickel Alloy Casting Manufactured?
Mold Development
We utilize advanced spectrometers to verify the precise mechanical properties of metal alloys, ensuring optimal performance in every casting.
Wax Pattern Production
Specialized wax injection machines extrude medium-temperature wax into precision molds, forming high-quality wax replicas of the final product.
De-burring the Wax Pattern
Each wax model undergoes meticulous inspection and precision trimming to guarantee flawless dimensional accuracy before further processing.
Pattern Assembly
Following engineered casting designs, individual wax patterns are carefully welded onto central wax runners to create complete casting clusters.
Shell Formation
A multi-layer ceramic coating process builds a heat-resistant shell around each wax assembly through successive dipping and stuccoing applications.
Shell Curing
The ceramic-coated clusters undergo controlled heating in industrial furnaces to achieve optimal strength and thermal stability.
Pouring
Molten steel is precision-poured into the preheated ceramic molds under carefully controlled conditions to ensure complete cavity filling.
Casting Extraction
After solidification, the cast components are separated from the shell structure and prepared for final finishing operations.
