MIM vacuum sintering furnace is a kind of equipment used in metal injection molding (MIM) process. It injects metal powder into the mold and then sinter it in a vacuum environment to form the desired shape and structure.
The core working principle of MIM vacuum sintering furnace is to heat the contact interface between powder particles under vacuum state to cause atomic migration, so as to realize the transformation of powder body into dense body. The whole process mainly includes steps such as blank preparation, debinding, vacuum sintering, cooling and post-processing.
Integrated process flow: degreasing and sintering processes are integrated into one furnace body, which can realize continuous production and improve efficiency.
High temperature control accuracy: multiple temperature zones with independent temperature control (±1℃ accuracy), temperature can reach 1600℃ (optionally higher).
Advanced degreasing system: adopts staged heating degreasing process, equipped with efficient exhaust gas treatment device.
Excellent vacuum system: the ultimate vacuum degree can reach 10^-3Pa, and a molecular pump can be optionally equipped to increase the pumping speed.
Flexible atmosphere control: supports multiple atmospheres such as vacuum, inert gas (N2, Ar), and can introduce reducing gas (H2).
Intelligent control system: PLC+touch screen control, can store multiple sets of process curves. With remote monitoring function.
Safety protection system: multiple protections such as overtemperature, overpressure, leakage, etc., emergency cooling system
Improve product quality: Through high-temperature sintering under a vacuum environment, impurities and gases in the material can be effectively removed, the density and purity of the material can be improved, and thus the mechanical properties and corrosion resistance of the product can be improved.
Save resources and energy: Adopt optimized heating elements and thermal insulation structures to reduce heat loss and reduce power consumption. At the same time, through a precise gas control system, the use of process gas can be saved.
Reducing production costs: The integration of degreasing and sintering processes has been realized, which reduces the production links and equipment footprint and improves production efficiency. In addition, the intelligent control system of the equipment helps to reduce labor costs and operating error rates.
Adapt to a variety of materials and processes: It is suitable for a variety of metal powders and binder systems, and can meet the manufacturing needs of metal parts of different shapes and sizes. By adjusting the process parameters, different sintering effects can be achieved, such as densification, precipitation strengthening, etc.
Good environmental performance: Equipped with an efficient waste gas treatment device, it can effectively treat the organic waste gas generated during the degreasing process and reduce pollution to the environment. At the same time, the equipment has good sealing performance to avoid the leakage of harmful gases.
