WDL-335 Vacuum High-Temperature Brazing Furnace | Molybdenum Heating Element Lab Furnace

WDL-335 Vacuum High-Temperature Brazing Furnace | Molybdenum Heating Element Lab Furnace | Ceramic & Titanium Alloy Brazing Equipment | WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD.

The WDL-335 Vacuum High-Temperature Brazing Furnace, manufactured by WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. , is a precision-engineered small vacuum brazing furnace designed for laboratory research and small-batch production. With an effective heating zone of 300×300×500mm, this compact vacuum furnace delivers industrial-grade performance in a space-saving footprint, making it an ideal choice for universities, aerospace component suppliers, and semiconductor material manufacturers.

Unlike conventional graphite furnaces, the WDL-335 utilizes high-purity molybdenum heating elements combined with all-metal heat shields (molybdenum + stainless steel). This design completely eliminates carbon contamination, ensuring superior joint quality when brazing sensitive materials such as titanium alloys, ceramics, stainless steel, and superalloys. Carbon diffusion is a primary cause of brittle joints and part failure—the WDL-335's carbon-free hot zone eliminates this risk entirely. The furnace meets AMS2750E standards with temperature uniformity of ±5℃, satisfying the most demanding requirements in aerospace, semiconductor, and medical device industries.

WUXI WONDERY brings over 15 years of vacuum furnace engineering expertise to this model, ensuring reliable performance, energy efficiency, and long service life.

Technical Specifications

Product Structure & Technical Features

1. Carbon-Free Heating System

The high-purity molybdenum heating elements release no carbon particles at high temperatures, fundamentally eliminating contamination of sensitive materials such as titanium alloys and ceramics. This makes the WDL-335 the ideal choice for reactive metal brazing and ceramic-to-metal sealing applications.

2. All-Metal Heat Shields

The heat shield pack consists of multiple layers of molybdenum and stainless steel sheets with smooth surfaces and extremely low outgassing rates. Compared to graphite felt insulation, this design enables faster vacuum recovery and eliminates the need for frequent replacement of aging insulation materials. Maintenance costs are reduced, and furnace cleanliness is significantly improved.

3. High Vacuum & Low Leak Rate

Equipped with a high-performance vacuum pumping system and WUXI WONDERY's mature vacuum manifold design, the furnace achieves high vacuum quickly and maintains an extremely low leak rate (≤0.5 Pa/h), providing a stable environment for critical brazing processes.

4. Intelligent Control System

The PLC + HMI touchscreen control system provides intuitive operation, real-time monitoring of temperature and vacuum levels, and full recipe management. Multiple process curves can be stored and recalled, and all data can be exported for process parameter optimization and quality traceability.

Why Choose the WDL-335?

• Carbon-Free Operation: All-metal hot zone design completely eliminates carbon contamination, ensuring highest quality when brazing titanium alloys, ceramics, and other sensitive materials.

• High Flexibility: The 300×300×500mm chamber is perfectly sized—large enough for small-batch production of medium-sized parts, yet compact enough to avoid energy waste. Ideal for high-mix, low-volume manufacturing.
