Mini Full Automatic Jewelry Vacuum Casting Machine 1kg Gold Capacity For Small Jewelry Studio

1. Product Overview

SSM-MN1 mini fully automatic vacuum pressure casting machine is a compact tabletop casting device tailor-made for jewelry studios, small handmade workshops and laboratory sample testing. Supporting dual voltage of 220V/380V, only 8KW power consumption and 1kg single-batch gold melting capacity, this mini unit takes up tiny workshop space while realizing full automatic melting, degassing, magnetic stirring and pressure casting.

It reaches a max working temperature of 1500°C and completes one melting cycle within just 2–3 minutes. Equipped with 300KPa stable casting pressure and ultra-precise temperature control up to ±0°C, it perfectly fits small 4"×5" casting flasks (both flanged and non-flanged). Built-in powerful magnetic stirring and independent degassing system effectively eliminates air bubbles inside molten gold, silver, copper and precious metal alloys, delivering flawlessly filled delicate hollow and filigree jewelry blanks with high finished yield. Integrated with a complete vacuum pump and intelligent program storage function, this mini casting machine is the ideal entry-level automatic casting equipment for small-scale jewelry production.

2. Core Advantages

1. Ultra-Compact Mini Body & Light Weight, Space-Saving Design Overall dimension only 685×560×934mm with net weight around 100kg, far smaller than standard casting machines. It can be placed on a workbench, perfectly matching small studios, home jewelry workshops and testing labs with limited floor space.
2. Dual 220V/380V Voltage Compatibility for Global Use Supports both single-phase 220V and three-phase 380V power supply, easy to deploy in different countries without extra transformer modification, greatly lowering installation threshold for overseas small jewelry businesses.
3. Low 8KW Power Consumption, Energy Efficient Small Batch Casting Low power design cuts daily electricity cost, matched with 1kg small gold melting capacity, dedicated for sample trial, custom small orders and delicate filigree jewelry mass small-batch production.
4. Full Automatic Intelligent Control with Program Memory Function Adopts independent automatic control system, can store multiple sets of casting parameters. One-click automatic operation covers melting, stirring, degassing and casting; new operators can get familiar with operation in a short time.

Powerful Magnetic Stirring & Independent Degassing for Fine Jewelry Built-in magnetic stirring evenly homogenizes alloy liquid; special degassing structure thoroughly removes internal air bubbles. Molten metal fully fills ultra-fine filigree, hollow and complex jewelry patterns, reducing scrap rate significantly.

1. Wide Material & Flask Compatibility Works well for gold, silver, copper and all mainstream jewelry alloys; compatible with 4"×5" standard flasks with or without flanges, matching most small-size jewelry casting molds.

3. Working Flow

1. Put the flask preloaded with wax jewelry patterns into the machine, recall saved casting programs via control panel.
2. 8KW heating unit rapidly heats precious metal raw material to 1500°C within 2–3 minutes.
3. Magnetic stirring homogenizes molten alloy while built-in degassing eliminates air bubbles to avoid pore defects.
4. 300KPa vacuum pressure pushes smooth molten metal to fully fill tiny mold cavities of filigree jewelry.
5. Automatic casting finished, take out the flask for cooling and subsequent jewelry blank processing.
