Introduction ：

Vacuum dewaxing furnace is a specialized heat treatment equipment used in the field of material preparation to remove wax and organic binders from wax-containing green bodies (or green bodies with organic binders). Its core function is to volatilize wax, decompose binders, and thoroughly discharge them through precise temperature control in a vacuum or inert gas protective environment, providing a clean green body foundation for subsequent processes such as sintering and smelting.It is widely applied in industries such as powder metallurgy, ceramic manufacturing, and precision casting.

Main Advantage

1.Superior Material Protection: The vacuum or inert atmosphere prevents oxidation or contamination of the green body, making it particularly suitable for oxidation-prone materials such as titanium alloys and aluminum alloys.

2.Higher Green Body Stability: Stepwise temperature control and low-stress dewaxing reduce the risk of cracking and deformation, adapting to complex-shaped and thin-walled green bodies.

3.Higher Dewaxing Cleanliness: Minimal residual wax provides high-quality green bodies for subsequent processes, reducing the defect rate of finished products.

4.Safe and Controllable Operation: Fully automated processes combined with multiple safety protections meet the needs of large-scale production. Meanwhile, it enables wax recycling to reduce costs.

5.Improved Processing Efficiency: The required heating time is shorter, which can enhance production efficiency.

Related Configuration

1.Heating Chamber

Heating Chamber : Circular/ Square

The heating chamber consists of a stainless steel frame, heat insulation layer, heating elements, insulation components, and a furnace bed. According to customer requirements, heating elements of different materials are selected for various scenarios to ensure furnace temperature uniformity, heat insulation performance, and sustainable use of the heating elements.

2.Vacuum system

Well-known domestic and foreign vacuum pump brands, such as EVP, Leybold, etc., are matched according to customer needs.

3.Control system

The operation control of this equipment is performed by the Siemens S7-1200 programmable logic controller. Interlock protection control is adopted for the equipment’s vacuum pump, valves, heating power supply, cooling fan, and other components. The system can judge and alarm abnormalities occurring during equipment operation, enabling fully automatic control. The network system supports remote network control and data transmission functions. All low-voltage components use international brands such as Siemens, Schneider, and Phoenix, which are highly reliable in terms of quality, performance, and craftsmanship, reducing the failure rate of the control system.

The network system supports remote network control and data transmission functions.

Remote fault diagnosis, remote process debugging, etc.

Supports software upgrade and update.

4.Other System

Our temperature measurement system adopts a nine-point temperature measurement method to monitor product temperatures in real-time and accurately, ensuring the uniformity of furnace temperature is maintained within the range of ±3℃ – ±5℃; the pneumatic system supports automated control via a touchscreen, enabling pneumatic control of the entire gas circuit; the inflation system can be set up once with no need for further adjustments, as on-off control is achieved through solenoid valves, making it simple, convenient, and easy to adjust; an independent water cooling system is equipped, mainly used to control the temperature of the furnace body, vacuum pump, and heating electrodes to maintain the normal operation of the vacuum furnace.
