Eliminate porosity, micro-bubbles, and incomplete fills in investment molds and resin pours with the Tabletop Vacuum Casting Machine XL Series (Models HH-CX01, HH-CX02, HH-CX03). Engineered for professional jewelry manufacturing studios, dental laboratories, modelmakers, and metalcraft artisans, this benchtop dual-function casting station integrates a spring-mounted investment vibrating pad with a dedicated negative-pressure perforated flask casting chamber.
Available in three motor configurations—2L / 375W (0.5 HP), 4L / 750W (1.0 HP), and 6L / 1000W (1.5 HP)—the XL series pulls deep vacuum through a high-displacement internal rotary vane pump, expelling trapped air pockets from thick gypsum slurries, RTV silicones, and polyurethane resins before pulling molten metals cleanly into perforated casting flasks. Each unit comes complete with an impact-resistant acrylic bell jar, heavy-duty perforated flask adapter gaskets, and sealing accessories ready for immediate bench integration.
Key Features & Benefits
-
Dual-Function Degassing Table & Casting Chamber: Combines an elevated 345 x 345 mm spring-cushioned degassing plate under a heavy-duty bell jar with an adjacent 140 x 190 mm vacuum casting well, handling both investment slurry bubble evacuation and molten metal pull-down on a single chassis.
-
High-Displacement Rotary Vane Vacuum System: Available in 0.5 HP (375W), 1.0 HP (750W), and 1.5 HP (1000W) configurations, pulling vacuum quickly to boil off trapped air before investment mixtures or rapid-cure resins begin setting.
-
Clear Acrylic Bell Jar with Dual Grab Handles: Features a high-tensile, transparent acrylic dome (325 mm diameter x 260 mm height) with side-mounted handles, giving technicians a full 360° view to monitor bubbling and boiling levels safely during degassing.
-
Multi-Port Directional Vacuum Control: Front-mounted directional selector valve routes vacuum draw directly between the investment table (“TABLE”) and the casting chamber (“CHAMBER”), with a dedicated quick-release valve (“RELEASE”) for immediate pressure neutralization.
-
Analog Vacuum Pressure Monitoring: An oil-filled, shock-resistant negative pressure gauge provides immediate visual verification of vacuum draw in both MPa and inHg.
-
Front-Accessible Dual Filtration Canisters: External clear filter housings trap gypsum dust, airborne investment powder, and moisture before they can enter and contaminate the internal pump oil, extending pump life and simplifying maintenance.
-
Spring-Suspended Vibration Damping Table: Heavy steel coil springs support the top plate to absorb vibration, isolate table wobble, and settle wet investment plaster evenly around delicate wax patterns.
