High Vacuum Single Chamber Tempering Furnace For Precision Metal Parts

This ultra-high vacuum temper furnace targets ultra-clean precision component production with strict surface & metallurgy standards. It equips three-stage vacuum unit (rotary vane pump + roots pump + diffusion pump) to reach ultimate vacuum up to 1×10⁻³ Pa, far higher than standard single chamber vacuum temper furnaces.

Full stainless steel hot zone without carbon pollution source, perfectly match medical implant parts, aerospace tiny alloy components and mirror stainless hardware which cannot accept any oxidation spot or carbon contamination. Independent inert nitrogen filling pipeline supports low-pressure protective atmosphere tempering for super precision thin-wall parts, no surface discoloration, zero post surface treatment required.

After placing micro precision parts inside all-stainless clean hot zone, three-stage vacuum pump continuously extracts air inside chamber to ultra-high vacuum state, removing all oxygen and impurity gas. Precision PID multi-zone heating maintains stable uniform temperature under oxygen-free environment, avoiding oxidation, decarburization and surface spots on ultra-precision thin components. Optional inert gas filling further reduces workpiece deformation risk during temper cooling stage.

Q1: What precision parts need ultra-high vacuum temper furnace instead of standard vacuum model?

A: Medical implants, aerospace alloy and mirror stainless parts with zero oxidation spot requirement; standard vacuum furnaces cannot reach enough clean vacuum to eliminate surface discoloration risk.

Q2: Is three-stage vacuum pump system complicated to maintain?

A: PLC automatic vacuum control with real-time pressure monitoring, one-button pump startup/shutdown, regular oil replacement only required for daily maintenance.
