Gravity Casting Machines

Gravity casting (also called permanent-mould casting) pours molten metal into a reusable metal mould under gravity alone — no pressure injection (like HPDC) and no gas pressure assist (like LPDC). It produces dense, fine-grain aluminium castings with excellent mechanical properties — better than sand moulding for thin sections, less capital-intensive than LPDC for medium-volume production. Best fit: aluminium cylinder heads, wheels, brake components and manifolds in the 1,000 to 100,000 parts-per-year range.

FMU1 for general aluminium parts where automated tilting reduces operator fatigue. FMU2 for static (un-tilted) gravity casting — simpler, lower capex, suited to low-volume or prototype runs. FMU/R 4-column servo rotary for complex parts where the tilt profile matters (multi-point pour, controlled fill velocity) — cylinder heads, complex impellers. FCL gantry-robot line for high-volume cylinder head production with integrated core inserting and cooling. Our engineering team scopes the platform to your part and annual volume.

Hydraulic tilting (FMU1) is simpler, lower capex, and adequate for parts with forgiving fill characteristics — typical aluminium gravity casting work. Servo tilting (FMU/R) gives programmable tilt-profile control — accuracy ±0.05°, up to 40 programmable pour points, repeatable fill velocity. Servo is preferred where mould fill behaviour materially affects scrap rate, typically on cylinder heads, complex pump bodies and thin-section castings.

Standard machines use independent heating zones for cope, drag and core — typically 250 to 400°C, with internal resistance heaters or oil-based circulation. The PLC holds each zone at a set-point and modulates heating during the cool-down portion of each cycle. The optional multi-zone oil-based mould-temperature controller (up to ≤350°C) gives finer control where critical-zone temperature stability affects fatigue properties or surface finish.

The platform spans the full production matrix — hydraulic single-station to fully automated cylinder-head islands — on a unified PLC control architecture, so operators trained on one machine transfer directly to the next. Critical components — servo motors, bearings, PLC, hydraulic valves, linear guides — are built around internationally proven names in Japan, Germany and Europe (Yaskawa, NSK, OMRON, Rexroth) for sustained accuracy and long service life. Cell integration with core making, melting and downstream fettling makes Stallion a single-source engineering partner for the complete gravity-casting line.
