Import Acme High Vacuum Tempering Furnace — Buy in wholesale FOB from Supplier in China

The Acme High Vacuum Tempering Furnace from ACME Corp is a vacuum heat treatment system designed for secondary thermal processing of tool steels, die steels, high-speed steels, ultra-high-strength steels and titanium alloys following primary vacuum quenching or solution treatment. The furnace operates under high vacuum conditions to minimise surface oxidation and decarburisation during tempering, preserving the metallurgical properties achieved in prior hardening processes. The unit also accommodates recrystallisation annealing and vacuum ageing cycles for non-ferrous metals, extending its utility beyond ferrous alloy processing.

Vacuum tempering typically operates in the 150-750°C range depending on target hardness and alloy system, with vacuum levels commonly achieving 10^-3 to 10^-5 mbar to prevent nitride and oxide formation on sensitive surfaces. ACME Corp manufactures this equipment in Muyun Industrial Zone, Changsha, Hunan Province, a region with established heavy machinery and heat treatment equipment manufacturing clusters. The furnace construction likely incorporates nickel-chromium or molybdenum alloy heating elements, multi-layer molybdenum or stainlessovic stainless steel radiation shields, and a diffusion or turbo-molecular pumping system, though buyers should request detailed component specifications for confirmation.

Target buyers include commercial heat treatment service providers, aerospace component manufacturers, tool and die shops, automotive tier suppliers and research institutions requiring controlled-atmosphere thermal processing. The furnace serves applications where atmospheric tempering introduces unacceptable surface degradation or dimensional change, particularly for precision cutting tools, aircraft landing gear components, and high-performance die casting dies. Trade terms, delivery schedule, installation support and warranty coverage must be confirmed directly with ACME Corp, as these are not stated in the available listing data.

ACME Corp operates from Muyun Industrial Zone, Changsha 410118, Hunan Province, China, positioning the company within one of China's central manufacturing corridors with access to heavy engineering supply chains and metallurgical expertise. The supplier carries a harbor trust tier designation, indicating a basic profile without independent verification of manufacturing capability, financial standing, or export track record. The response rate is recorded at 0.00% with zero average response hours, suggesting that direct outreach through alternative channels such as telephone, trade fair contact, or industry referral may be necessary to establish communication.

The listing presents ACME Corp as a manufacturer of vacuum heat treatment equipment, specifically targeting post-quench tempering applications for demanding alloy systems. No information is provided about establishment year, registered capital, production floor area, workforce size, R&D investment, installed base, or client references. Buyers should conduct thorough due diligence including factory audit or video verification, request ISO 9001 or equivalent quality system certification, and seek references from existing users of ACME Corp vacuum furnaces in comparable applications before committing capital expenditure.
