Most buyers arrive already knowing they want vacuum and pressure in one melting cycle; the harder question is which capacity class fits the bench. This guide lines up the TAKJ-VC, VC05 and VC2 so you can compare vacuum pressure casting machine machines by gold capacity, voltage and flask size instead of by brochure wording, and it shows what to settle with a vacuum pressure casting machine manufacturer before a custom build is confirmed.
01 / Compare the models
Capacity and electrical supply separate these models faster than any other column. Read across the row for your target gold weight, then check the voltage you actually have on site.
| Model | Capacity (gold) | Voltage / phase | Power | Max temperature | Temp accuracy | Pressure | Max flask size | Metals |
|---|---|---|---|---|---|---|---|---|
| VC05 | 500 g | 220 V, 50/60 Hz, single phase | 5 kW | 1500 °C | ±1 °C | 0–3 bar casting pressure (adjustable) | 4" x 10" inch | Gold, silver, copper, alloys |
| VC2 | 2 kg | 380 V, 50/60 Hz, 3 phases | 8 kW | 1500 °C | ±1 °C | 0–3 bar casting pressure (adjustable) | 4" x 10" inch | Gold, silver, copper, alloys |
| TAKJ-VC | 500 g – 4 kg optional | 380 V three phase, 50/60 Hz | 30 kW max | 1500 °C | ±1 °C | 10–120 kPa adjustable pressurising pressure | Not stated — confirm on quote | Platinum, gold, silver, copper, alloy |
| TAKJ-VC-W | Configured to order (narrative mentions 1–5 kg) | 110 V / 220 V / 380 V options mentioned | Confirm on quote | Confirm on quote | ±1 °C (PID control panel) | Confirm on quote | Confirm on quote | Precious metals per configuration |
Note: the VC05 and VC2 are bench and shop production class machines with POKA YOKE foolproof operation; the TAKJ-VC and TAKJ-VC-W are built to order and their notes are confirmed on the quotation.
Ask for the written specification sheet for your exact configuration before an order is placed, so the temperature ceiling, capacity and pressure range on the quotation match what you will run.
02 / Route by scenario
Each scenario below maps to a concrete configuration and to the one value you should confirm before you commit.
Scenario 01
A single bench running short gold and silver runs fits the VC05 class: 500 g gold capacity, 220 V single-phase supply and 5 kW power in a compact enclosure.
Scenario 02
When daily output sits in the 2 kg band and you already run three-phase power, the VC2 class doubles the gold capacity of the bench unit at 8 kW.
Scenario 03
The feature description states a 2100 °C setting for platinum, palladium and rhodium, with 1600 °C kept for gold, silver and lower-temperature metals.
Scenario 04
The TAKJ-VC-W build is configured to order, with capacity options across the range plus voltage adjustment, interface language and OEM casing discussed at quotation.
03 / Feature to defect
Casting problems are rarely a single failure. The useful way to read a machine's feature list is to ask which defect each item removes from your finished piece, and then decide whether that defect costs you more than the step up in specification.
Melting and casting chambers are completely independent, and the pressure difference controls injection of the metal into the mould during pouring.
Incomplete fill and misruns on thin sections
A high-vacuum environment is held under 10–120 kPa pressurising pressure, so the metal does not meet air during the pour.
Oxidation loss, bubbles and porosity
The page states vibration reduces losses, optimises quality and delivers what it describes as the most perfect product surface with the least processing.
Trapped gas and heavy post-cast finishing
The PID panel holds the temperature difference to ±1 °C, and the Mitsubishi human-machine interface supports a one-click casting cycle.
Temperature drift between one cast and the next
Induction coils and intelligent heating logic are described as using less electricity than traditional resistance systems, inside a sealed system.
Metal loss and energy waste on every melt
The machine is described as a compact, fully enclosed unit intended for jewelry workshops and small laboratories.
Uncontrolled shop dust and open-flame handling around the melt
04 / Metal and temperature
The page describes two temperature settings rather than one fixed ceiling. Which one applies to you depends entirely on the metal group in your flask, so decide the metal first and the machine specification second.
| Metal group | Setting described | What to confirm |
|---|---|---|
| Gold, silver | 1600 °C setting for low-temperature metals | Specification tables list 1500 °C as the maximum |
| Copper, alloys | Listed among melting metals for the parameter block | Casting pressure range for the alloy you use |
| Platinum, palladium, rhodium | 2100 °C setting per the feature description | Written confirmation of the rated maximum |
| Atmosphere | Argon or nitrogen listed for VC05 and VC2 | Gas supply and regulator sizing on site |
The two temperature figures on the product page do not agree. Treat 2100 °C as a setting that must be confirmed for your configuration, and do not plan platinum-group production on the assumption that every model in the range carries the same ceiling.
05 / Capacity and floor planning
Gold capacity tells you how much metal one cycle can handle. Throughput comes from the melt time you repeat, and floor planning comes from the footprint and weight of the cabinet. Plan all three together before you pick a class.
06 / Built to order
The page describes custom-built options rather than a single fixed export version. If your workshop runs on 110 V, needs a specific interface language, or wants an OEM casing, those details are settled at quotation stage — which means the quote request should carry them from the start.
07 / After the order
A casting machine is a long-running bench asset, so the questions worth asking are about what happens in year two, not only what the cabinet does on day one.
Send the metal you cast, the gold weight per flask, your voltage and phase, the flask size you buy and the interface language you need. Those five details are what turn a general quotation into a machine specification you can compare line by line.
