Single-Chamber Vacuum Tempering Furnace for Bright Stress Relief

Single-Chamber Vacuum Tempering Furnace is an integrated single-chamber heat treatment equipment. All processes including heating, soaking and gas cooling are finished inside one sealed vacuum vessel without separate transfer or cooling chamber. Compact footprint & easy operation make it ideal batch production furnace for bright tempering, stress relieving and aging annealing after quenching.

Working under high vacuum or inert protective atmosphere, it completely avoids oxidation & decarburization of metal parts. Workpieces stay bright metallic surface without post polishing. Equipped with forced convection heating & high-pressure gas cooling system, it delivers uniform temperature field, eliminates internal quenching stress and prevents temper brittleness. Widely applied for die steel, HSS, stainless steel, bearing steel and non-ferrous precision components.

1.Bright Oxidation-Free Workpiece Surface High vacuum sealing structure cuts off air contact, no oxide scale or discoloration after tempering, save post-processing cost of sandblasting & pickling.

2.Uniform Temperature Field, Stable Heat Treatment Quality Forced circulation convection fan ensures tiny temperature difference inside chamber, consistent hardness & toughness for mass production, meet high-standard precision part manufacturing demand.

3.Compact Single Chamber Design, Space Saving All processes finished in one vessel, floor area only half of double-chamber furnace, perfect for small & medium heat treatment factories.

4.Fully Automatic Intelligent Control, Labor Saving PLC touch screen control system, store dozens of heat treatment recipes, auto run full cycle without manual operation. Support real-time curve recording & data export for quality traceability.

5.Energy Saving & Low Maintenance Cost Multi-layer metal heat shielding structure reduces heat loss by 20%, heating elements and vacuum spare parts are easy to replace for overseas after-sales service.

6.Full Safety Interlock System, CE Certified Door lock interlock, over-temperature power cut, water shortage protection, over-pressure relief and fault alarm system, comply with EU industrial safety standards.

Q1: Single chamber vs double chamber furnace, which one to choose?

A1: Single chamber is more cost-effective for small & medium batch production, limited factory space and tight budget. Double chamber fits mass 24h continuous production and ultra-high anti-oxidation requirement.

Q2: Do workpieces need polishing after tempering?

A2: Parts treated under high vacuum & pure nitrogen atmosphere keep bright metallic surface without oxidation or discoloration, only simple cleaning required, no sandblasting or polishing needed.

Q3: Can the furnace be customized for export? Can I change chamber size & voltage?

A3: Full customization available: chamber dimension, max temperature, vacuum system, imported PLC brand, industrial voltage 220V/380V/415V for EU & Southeast Asia, remote monitoring module optional.

Q4: What about sea packing & warranty service?

A4: Machine packed with vacuum moisture-proof film & fumigated wooden case for ocean transport. 12 months full machine warranty, permanent spare parts supply, English operation manual, remote installation guidance.
