Vacuum investing casting machine for jewellery

The VEVOR vacuum investing casting machine combines a 290W motor with a 3 CFM pump and an 11 x 11 in bell jar to remove air bubbles from dies and flasks. It is built for jewellers, dental labs and small foundries that need reliable degassing before pouring metal or resin. The cold-rolled steel frame weighs 59.08 lbs and measures 19.3 x 10.8 x 15.8 in, so it sits on a bench without special mounting.

Sustained vacuum performance

The 3 CFM pump maintains continuous suction during long casting cycles, while the thickened hood holds vacuum evenly across the 280 x 280 mm platform. A top-mounted oil filling port accepts 46# vacuum oil up to 400 ml without removing the rear panel, and the heat-dissipating back panel keeps the motor cool during repeated runs. The precision gauge lets the operator watch pressure drop in real time and stop exactly when bubbles are gone.

Platform size and flask compatibility set

The 11 x 11 in workbench fits the included perforated flask with a 3.5 in hole section and the three stainless rings sized at 18 mm, 89 mm and 110 mm inner diameter. Larger flasks or taller moulds will not seal under the bell jar, so production runs are limited to pieces that sit inside the 280 x 280 mm footprint. Oil is not supplied, and the single-phase 290W motor requires a standard mains supply.

Questions about this item

How hot or noisy does the 290 W motor get during a full day of casting?

The machine uses a cold-rolled steel frame with a heat-dissipating back panel to manage the 290 W draw, but the supplier gives no decibel or surface-temperature figures.

Which vacuum oil must I supply before the first run?

You need 400 ml of 46# vacuum oil; the top-mounted filling port makes topping up simple, but the oil is not included in the box.

Will my existing 3.5-inch flasks seal correctly on the 11 × 11 in platform?

Yes — the kit includes a 3.5 in perforated flask with sleeve, a matching pouring-base gasket and three stainless steel rings (18 mm, 89 mm, 110 mm ID) that all seat on the 280 × 280 mm hood.
