The Weibulen 5L Atmosphere Protection Internal Mixer is primarily used for the mixing and dispersion of materials such as titanium alloys, copper alloys, aluminum alloys, and tungsten alloys. It employs imported oxygen content detection instruments to ensure accurate readings; the entire machine adopts multiple sealing devices to ensure no air leakage, enabling experiments to be completed with minimal gas consumption. Since its launch, the Weibulen 5L Atmosphere Protection Experimental Internal Mixer has gained widespread recognition from numerous MIM manufacturers.

I: Features of the Weibulen 5L Atmosphere Protection Internal Mixer
1: The mixing chamber and rotors are made of new alloy steel material, undergoing special vacuum heat treatment, CNC machining, and surface mirror polishing, ultimately achieving overall steel wear resistance and corrosion resistance (salt corrosion, acid corrosion, alkali corrosion, hydrogen sulfide corrosion, and various other types of corrosion).
2: Servo coaxial separation technology, easy cleaning and material change
Utilizing advanced servo coaxial separation technology, the rotor can be separated with one end face as the axis, breaking through the bottleneck of traditional internal mixers. The open-close internal mixer effectively controls unnecessary economic losses caused by material contamination. While the mixing chamber opens and closes, the rotor remains suspended in the middle, facilitating easy cleaning and material change. The rotor is detachable, allowing staff to clean any part, with an all-around, dead-angle-free design.
3: The industry-first vacuum extraction + atmosphere protection mode significantly reduces gas filling time
A: Vacuum extraction
Most of the air can be extracted in a short time, greatly reducing gas filling time.
B: Inert gas introduction (nitrogen or argon)
Users can set the upper and lower limits of oxygen content, and the equipment automatically starts and stops the inert gas switch, significantly saving gas consumption.
C: Oxygen content detection
A: Equipped with upper computer software, it can connect to a computer for real-time monitoring, recording, saving, and data export.
B: Original imported sensor, automatic temperature, zero point, and full-scale drift compensation.
C: Protection against high-concentration gas impact and self-diagnosis function for sensor faults, ensuring safety and reliability.
D: Detection accuracy: ≤±3% (F.S)
E: Zero drift: ≤±1% (F.S/year)
F: Linearity error: ≤±1%

4: PLC system automatic gas replenishment
The equipment adopts a PLC control system, which combines preset values and real-time detection to intelligently operate positive pressure to expel oxygen content during operation and automatically replenish inert gas. This ensures that the entire working process meets the requirements of material mixing, thereby achieving better mixing results.
