MIM sintering furnace

MIM (Metal Injection Molding) sintering furnace is a key equipment used in the metal injection molding process. It is mainly used to inject and degrease the mixture (feed) of metal powder and binder, and then perform high-temperature sintering to finally form high-density and high-precision metal parts.

Main features of MIM sintering furnace

High temperature sintering: MIM sintering furnaces typically require high temperatures ranging from 1300 ° C to 1600 ° C to meet the sintering needs of different metal materials.
Atmosphere control: During the sintering process, precise control of the furnace atmosphere (such as hydrogen, nitrogen, argon, or vacuum) is required to prevent metal oxidation and ensure sintering quality.
Temperature uniformity: The uniformity of temperature distribution inside the furnace is crucial for the performance of the parts, and it is usually required to control the temperature difference within ± 5 ° C.
Integration of debinding and sintering: Some MIM sintering furnaces support the integration of debinding and sintering processes, reducing production steps and improving efficiency.
Automation control: Modern MIM sintering furnaces are usually equipped with PLC or computer control systems to achieve automated management of temperature, atmosphere, and process parameters.

Components of MIM sintering furnace

Furnace body: including heating elements, insulation materials, and furnace structure to ensure stable high-temperature environment.
Heating system: Usually using resistance heating or induction heating methods.
Atmosphere control system: including gas supply, flow control, and exhaust system.
Cooling system: used for rapid cooling after sintering to improve production efficiency.
Control system: used to monitor and regulate temperature, atmosphere, and process parameters.

Application of MIM sintering furnace

MIM sintering furnaces are widely used in the following fields:

Automotive industry: Manufacturing complex shaped components such as turbocharger blades, gears, etc.
Medical industry: producing high-precision parts such as surgical instruments and dental implants.
Consumer electronics: used for manufacturing small precision components such as mobile phones and watches.
