Vacuum Atmosphere Box Type Sintering Furnace For Thermistor PTC NTC 180L SUS304 20kW

TAILORD Box Furnace for Debinding & Sintering of Thermistor

Precision Thermal Processing for Stable Resistance & High Reliability

The manufacturing of high-performance Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC) thermistors demands precise control over the critical thermal cycles that define their electrical characteristics. TAILORD's Box Furnaces are engineered to master both the delicate debinding and high-temperature sintering stages. We provide robust, uniform, and repeatable thermal processing in a single, versatile platform, ensuring the production of thermistors with stable resistance, precise Beta (B) values, and exceptional long-term reliability for the automotive, consumer electronics, and industrial markets.

Key Features & Process Advantages:

1. Optimized Two-Stage Thermal Processing: Our box furnace is ideally configured for a streamlined workflow. It expertly handles the low-temperature debinding of organic binders from printed pastes or molded bodies, followed by the high-temperature sintering that establishes the final ceramic microstructure and electrical properties, all within a robust and easy-to-use system.

2. Complete & Controlled Binder Removal: The furnace's precise programmable controller allows for meticulously slow ramp rates in the critical low-temperature zone. This ensures the complete volatilization and removal of polymers and plasticizers without causing blisters, cracks, or carbon residue, which are detrimental to stability and performance.

3. Superior Temperature Uniformity for Batch Consistency (±3°C): Engineered with advanced heating elements and chamber design, the furnace guarantees exceptional temperature uniformity throughout the entire workspace. This ensures every thermistor in a batch sinters under identical conditions, which is fundamental for achieving tight resistance tolerances and consistent Beta (B) values.

4. Atmosphere Versatility for Material Needs: While perfect for air atmosphere sintering of oxide-based NTC materials, the robust chamber design also supports the use of controlled atmospheres (via optional inlet/outlet ports) for challenging processes, such as preventing the oxidation of specific dopants or managing the atmosphere for certain PTC formulations.

5. Robust Construction for Industrial Reliability: Built with high-quality refractory materials and durable heating elements, TAILORD Box Furnaces are designed for reliable performance in demanding laboratory and small-batch production environments. This ensures high uptime, process repeatability, and a low total cost of ownership.
