Key criteria
Metallurgy: nitrided or bimetallic barrel; wear class and hardness.
Drive/gearbox: low vibration, easy maintenance.
Thermal control: zoned PID, proper TC placement, air/water cooling.
Automation: recipe management, trend logging, secure remote access.
Energy: VFDs, insulation, optimized zone layout.
After-sales: commissioning, operator training, spare parts.
