1. High Temperature Oven Product Overview
A high temperature oven is an industrial thermal processing apparatus, typically referring to a heating chamber operating between 300°C and 760°C, designed to perform baking, drying, curing, heat treatment, and material testing through forced hot air circulation. Compared with standard industrial ovens (generally operating below 350°C), high temperature ovens demand higher standards in insulation structure, heating element materials, fan temperature ratings, and control system precision. A typical high temperature oven features a SUS304 stainless steel inner chamber, aluminum silicate wool insulation, a high-temperature centrifugal fan, and a PID intelligent temperature control system, achieving temperature control accuracy of ±1°C and temperature uniformity within ±2%. Applications span aerospace, electronics manufacturing, chemical processing, pharmaceuticals, food processing, automotive coating curing, new energy material sintering, and scientific research.

High Temperature Oven Technical Advantages
Nanjing Zhuoding's HGW series high temperature ovens constitute its core product line, offering significant advantages in structural design and control precision. The ovens feature a SUS304 stainless steel inner chamber, an A3 steel plate powder-coated outer shell, double-opening doors, and an integrally molded silicone rubber door seal that ensures excellent airtightness and operational convenience. The temperature control system employs a touch-button PID intelligent controller paired with a Pt100 platinum resistance temperature sensor, providing sensitive temperature regulation, simple operation, and direct digital display of the working temperature-11. The protection system consists of over-temperature protection and alarm devices that automatically cut off power under abnormal conditions, safeguarding both equipment and workpieces-11. In terms of temperature capability, standard models cover room temperature to 300°C, while high-end models reach 500°C, meeting the vast majority of industrial high-temperature processing requirements.
The HGW series ranges from the HGW-1A (chamber dimensions 350×450×450 mm) to the HGW-11B (2000×2000×2000 mm), covering equipment from small laboratory units to large-scale batch production systems, with flexible chamber dimensions to suit actual capacity needs-11. Additionally, the company offers customized designs for special process requirements, including non-standard dimensions, special atmosphere control, and explosion-proof configurations.
