Zhejiang Nengcheng Crystal Fiber Co., Ltd. designs and builds experimental, industrial, and non-standard customized vacuum electric furnaces for heat treatment processes across ceramics, metallurgy, electronics, glass, and chemical engineering. As a direct Vacuum Electric Furnace manufacturer in China, we integrate our own ultra-lightweight refractory materials to improve energy efficiency and thermal uniformity.
We supply a broad family of vacuum electric furnaces, each configured around the specific process, work piece geometry, and production target. The table below summarizes the main types we offer and where they fit.
| Product Type | Typical Applications | Key Configuration Points |
|---|---|---|
| Vacuum Annealing Furnace | Stress relief, recrystallization, bright annealing of stainless steel, copper, titanium, and other alloys | Heating element material, vacuum level, cooling rate, charge size |
| Vertical Vacuum Brazing Furnace | Joining of aerospace, automotive, and electronic components without flux | Vertical hot zone, temperature uniformity, vacuum integrity, fixture design |
| Vacuum Molybdenum / Tungsten Wire Furnace | Sintering and heat treatment of refractory metals, ceramics, and high-temperature materials | High-temperature heating elements (Mo, W), hot zone insulation, atmosphere control |
| Vacuum Carbon Tube Furnace | Graphitization, carbon fiber processing, sintering of carbon-based materials | Graphite heating elements, high vacuum, inert gas backfill, temperature range |
| Low Temperature Vacuum Annealing Furnace | Annealing of non-ferrous metals, glass-to-metal seals, and sensitive electronic components | Precise low-temperature control, uniform heating, fast cooling options |
| Sapphire Annealing Furnace | Post-growth annealing of sapphire crystals for optical and semiconductor applications | High temperature stability, controlled cooling, clean vacuum environment |
| Industrial Lifting Sintering Furnace | Sintering of ceramics, powder metallurgy parts, and advanced materials | Bottom-loading design, atmosphere control, high-temperature uniformity |
| Continuous Rotary Kiln / Roller Kiln | Continuous processing of powders, granules, and small parts in vacuum or controlled atmosphere | Throughput, retention time, temperature profile, sealing system |
| Laboratory Nitrogen Atmosphere Box Furnace | R&D, small-batch heat treatment, and material testing under nitrogen atmosphere | Compact footprint, programmable control, gas flow regulation |
We also supply Industrial Furnace systems beyond vacuum, including tube and muffle furnaces, and we manufacture the thermal insulation materials used inside our own equipment.
Every vacuum electric furnace we deliver is engineered around the process requirements, not a standard template. We start with the working temperature, vacuum level, heating and cooling rates, and the physical dimensions of the charge. From there we select the appropriate heating element—molybdenum, tungsten, or graphite—and design the hot zone using our own lightweight refractory fiber materials to minimize heat loss and improve temperature uniformity.
We also configure the control system to match your production environment. Options include manual or programmable logic controllers, touch-screen interfaces, data logging, and integration with existing line automation. For atmosphere-sensitive processes, we can add gas backfill, mass flow control, and overpressure protection.
Our furnaces are built for both laboratory and industrial duty. Laboratory units are compact and often used for material research, powder roasting, and ceramic sintering. Industrial units are designed for continuous or batch production with higher throughput, more robust mechanical construction, and safety interlocks.
We operate under ISO9001 and CE quality management systems. Each furnace undergoes inspection at every manufacturing stage, and finished units are fully tested according to customer specifications and international standards. We also hold a utility model patent related to our furnace design, and we provide inspection reports with each shipment.
Before delivery, we perform vacuum leak tests, temperature uniformity surveys, and functional checks of all safety systems. We can also run process trials with your material samples to validate the furnace performance before you commit to full production.
As a manufacturer with in-house design, R&D, and engineering services, we support projects from specification to commissioning. We assist with furnace installation, operator training, and process development. Our service team can also handle repair, modification, and relocation of vacuum furnaces, as well as maintenance of vacuum pumps and supply of spare parts.
We work with universities, research institutes, and industrial plants, providing equipment for powder roasting, ceramic sintering, and high-temperature experiments. Our goal is to deliver a furnace that meets your exact process needs and remains reliable over years of operation.
To prepare a precise proposal and quotation, we need the following project inputs:
With this information, we can recommend the appropriate furnace type, heating element, hot zone design, and auxiliary equipment. We also provide layout drawings and utility connection details before manufacturing begins.
In addition to vacuum electric furnaces, we offer High Temperature Tube Furnace and High Temperature Muffle Furnace systems for atmosphere and air environments. Our Thermal Insulation Materials are also available separately for furnace rebuilds and upgrades.
Yes. We specialize in non-standard customized electric furnaces. We work from your process parameters and can adapt the hot zone, heating elements, vacuum system, and control logic to meet specific requirements.
Lead time depends on complexity and current production load. After we receive your specifications, we provide a delivery schedule with the quotation. Standard models are faster, while fully custom systems may require additional engineering time.
Yes. Our engineering team can supervise installation, perform commissioning, and train your operators. We also provide documentation including layout drawings, utility requirements, and maintenance manuals.
We can run process trials using your material samples in our laboratory or pilot furnaces. This helps validate temperature profiles, atmosphere requirements, and cycle times before finalizing the furnace design.
We provide spare parts, maintenance services, and technical support for the life of the furnace. Our service team can also assist with furnace relocation, modification, and vacuum pump repair.
