1. Working principle

Defatting stage:

In a vacuum or specific atmosphere environment, the adhesive in the workpiece is gradually softened and decomposed by heating, and then discharged from the furnace through a vacuum system.

During the degreasing process, precise control of parameters such as temperature, vacuum degree, and time is required to ensure that the adhesive can be completely and uniformly removed, while avoiding deformation or cracking of the workpiece.

Sintering stage:

After degreasing is completed, continue to raise the temperature to the sintering temperature, allowing the metal or ceramic particles in the workpiece to diffuse and combine at high temperatures, forming a dense solid structure.

Accurate control of temperature, vacuum degree, and holding time is also required during the sintering process to achieve the desired sintering effect.

2. Structural characteristics

Double or single room design:

The degreasing and sintering integrated vacuum furnace usually adopts a dual chamber design, that is, the degreasing chamber and the sintering chamber are separated to avoid the gas generated during the degreasing process from contaminating the sintering process.

Some equipment also adopts a single chamber design, but special process control is required to ensure the smooth progress of degreasing and sintering processes.

Vacuum system:

Equipped with high-performance vacuum pump units, it can quickly extract air and maintain a high vacuum environment inside the furnace.

Vacuum systems typically include mechanical pumps, Roots pumps, and diffusion pumps to meet the vacuum requirements of different process stages.

heating system

By using resistance heating method, the temperature distribution inside the furnace can be precisely controlled.

Heating elements are usually arranged around or at the bottom of the furnace to ensure uniform heating of the workpiece.

Control system:

Equipped with advanced control system, it can achieve precise control and automatic recording of temperature, vacuum degree, time and other parameters.

Control systems typically have user-friendly interfaces and easy operation, making it convenient for operators to monitor and adjust process parameters.

3. Application advantages

Improve production efficiency:

The degreasing and sintering processes are completed in the same equipment, avoiding the transfer and waiting time of workpieces between different devices and improving production efficiency.

Ensure product quality:

The degreasing and sintering processes are carried out in a vacuum environment, avoiding reactions between the workpiece and oxygen, nitrogen, etc. in the air, ensuring the quality and performance of the product.

Accurate process control can ensure that the workpiece does not undergo defects such as deformation or cracking during the degreasing and sintering processes.

Reduce production costs:

The degreasing sintering integrated vacuum furnace usually has a high degree of automation, reducing manual operation and intervention, and lowering production costs.

At the same time, due to the efficiency and stability of the equipment, the maintenance and repair costs of the equipment are also reduced.

4. Selection suggestions

When choosing a vacuum furnace that integrates degreasing and sintering, the following factors need to be considered:

Process requirements:

Select appropriate equipment models and specifications based on specific process requirements, including furnace size, heating temperature range, vacuum degree range, etc.

Productivity

Consider factors such as heating speed, cooling speed, and automation level of the equipment to improve production efficiency.

Product quality requirements:

Select appropriate process control precision and stability according to product quality requirements to ensure product consistency and reliability.

After sales service and technical support:

Choose a manufacturer with good after-sales service and technical support to obtain timely technical support and maintenance services during use.
