Based on these designs, precision metal tooling is manufactured for wax pattern injection.
Proper tooling design is essential because it determines casting accuracy, dimensional repeatability, and production efficiency throughout the product lifecycle.
Vaska modeļa ražošana
Molten wax is injected into the tooling to produce an accurate replica of the final nozzle.
Multiple wax patterns are assembled onto a central runner system to form a casting tree, allowing numerous components to be produced in a single casting cycle.
The high dimensional consistency of wax patterns ensures uniformity between production batches and minimizes variation during subsequent processing.
Keramikas apvalka ēka
The wax assembly is repeatedly coated with refractory slurry and fine ceramic sand.
Each coating layer is dried before the next is applied until a strong ceramic shell of sufficient thickness is formed.
The ceramic shell must withstand molten stainless steel temperatures exceeding 1,600°C while maintaining dimensional stability throughout pouring and solidification.
Atkāpšanās un čaumalas šaušana
After shell preparation, the wax is removed using high-pressure steam or autoclave dewaxing, leaving a hollow ceramic mold.
