Integrated machinery capacity & dimensional envelopes
Core Precision Investment Casting Equipment
In investment casting raw blank production, VastCasting operates automated shell lines and temperature-controlled melting equipment to ensure dense internal structures. Our comprehensive facility equipment enables a seamless workflow from wax pattern formation to high-purity alloy melting and uniform thermal processing for overseas engineering audits.
Automated Wax & Shell Production
Utilizing high-precision dual-station wax injectors and robotic automated shell-making cells, our mold production process reduces dimensional tolerances, maintains slurry consistency, and stabilizes ceramic shell strength across all production runs for industrial components, including specialized valve body fittings.
Melting & Thermal Processing
Engineered with medium-frequency induction melting furnaces and advanced vacuum induction melting (VIM) furnaces, our system delivers exact alloy stoichiometry, minimizes porosity, and guarantees uniform microstructure through controlled heat treatment for high-spec superalloy high temp castings.
