Conductive Heating for Fast Eutectic Joining
Eutectic Furnace is a vacuum heating system with a pit-type structure designed for rapid welding and eutectic joining of workpieces.
The furnace uses metal heating tubes to generate heat. A heat-conducting plate is installed inside the working area, and the workpieces are placed directly on this plate.
Heat is transferred from the heating system through the plate to the workpiece and joining position.
Compared with a structure that depends mainly on slower air heating or radiation heating inside the chamber, the heat-conducting plate configuration is more suitable for processes requiring faster heating and localized joining.
The equipment can therefore be used for precision component welding, packaging, and related heat treatment.
550°C Working Temperature with Five Chamber Options
The furnace liner is made from 304 stainless steel.
Ceramic fiber cotton is used as the insulation layer, while the outer structure is carbon steel. Circulating water cooling is arranged between the inner and outer layers.
The working temperature is 550°C.
Rated voltage is 380 V, and metal heating tubes are used as the heating elements.
The listed heating rate is 1–10°C/min.
The vacuum range is from -0.1 MPa to 6.67 × 10⁻⁴ Pa.
Five chamber sizes are available: 300 × 200 × 200 mm, 500 × 400 × 400 mm, 600 × 300 × 300 mm, 600 × 400 × 400 mm, and 800 × 500 × 500 mm.
Their corresponding power ratings are 4 kW, 8 kW, 10 kW, 14 kW, and 25 kW.
Selection Based on Conductive Plate and Workpiece Layout
The supplied information lists applications in laser devices, aerospace, and electric vehicles.
For an Eutectic Furnace, buyers should consider the workpiece contact area with the conductive plate, fixture height, batch quantity, required vacuum level, and welding temperature curve.
The chamber size should therefore be selected together with the required conductive plate area and workpiece arrangement.
This purchasing approach is different from choosing a standard furnace only by maximum temperature.
The ceramic fiber cotton insulation is used to reduce heat transfer toward the outside of the furnace, while the circulating cooling system helps control furnace body temperature during operation.
OEM Parts, Inspection and Transportation Handling
Nengcheng Crystal can supply ceramic fiber cotton, insulation covers, and vacuum-formed insulation components used with this type of furnace.
The company has 11 years of factory operating experience and a team of 45 employees, including R&D and dedicated inspection personnel.
OEM and ODM processing can be discussed according to technical drawings or physical prototypes.
Orders can start from one unit, and samples or components can be confirmed before larger-volume production.
Products are normally inspected before packaging, and third-party inspection is accepted.
Wooden cases or wooden pallets can be used for equipment shipment. If transportation damage is found, buyers can retain photos and videos so replacement parts can first be discussed before the cause is investigated further.
