Ceramic Band Heater Supplier for High-Precision Injection Molding Machines

JIEO is an electric heating element manufacturer with over 17 years of experience in China. JIEO’s ceramic band heater is a high-temperature, long-lasting electrical band heater in the industry. These ceramic band heaters can reach the higher operating temperatures required by today’s industries, especially in the chemical and synthetic fiber sectors, engineering plastics, high-precision injection molding machines, melt-spun fabric extruders, and various pipe-heating applications.

Ceramic Band Heater

Ceramic band heaters can reach high temperatures while efficiently transferring heat, reducing heat loss, and maintaining a stable heated surface. They transfer heat through both conduction and radiation. The coiled design of the heating element ensures that, when operating at high temperatures, the ceramic knuckles are adequately heated to radiate heat to the tank body and conduct heat through contact. As a result, a precise fit during installation is less critical than it is for other types of heating bands.

Energy saving
Heats through conduction and radiation with minimal heat loss.
High thermal efficiency
Thanks to efficient heat conduction and insulation design, thermal efficiency typically exceeds 90%.
Long-term service life
Provides fast heat transfer, even heat distribution, and stable operation.
Safety and reliability
Offers excellent insulation performance and high-voltage resistance.
Easy installation
Features a fully flexible construction design for simple setup.

What Does JIEO Make In The Ceramic Band Heater

JIEO’s Ceramic Band Heater is designed and engineered to meet the growing demand for energy efficiency and improve operational performance.

Our ceramic band heaters’ resistance wire is nickel-chromium (Cr20Ni80), machined into a helically wound resistance coil. And then stretched and precisely strung through specially ceramic knuckles. These specially ceramic knuckles are available in steatite (95% Al₂O₃/99% Al₂O₃) with low dielectric loss factor, in white, yellow, and pink. Forming a flexible heating mat.

Our insulation includes ceramic fiber and natural mica. They have excellent insulation performance, high-temperature resistance, and low thermal conductivity. These factors contribute to the ceramic band heater elements’ excellent thermal efficiency and significant energy-saving benefits. These advantages further help high-precision machinery operate effectively during plastic melting and injection molding, ensuring consistent product quality and reducing energy consumption.

The top of the ceramic band heater, with a stainless-steel housing and serrated edges for flexibility, ensures structural stability and ease of installation.

Differences Between JIEO’s Ceramic Band Heater Insulations

Type 1: JIEO’s Standard Ceramic Band Heater

The standard JIEO ceramic band heater is constructed using a helically wound resistance coil
made from nickel-chrome (Cr20Ni80) wire. The coil is stretched and precisely threaded through
ceramic knuckles (steatite: 95% Al₂O₃ / 99% Al₂O₃), forming the core heating element.

The assembly is then insulated with ceramic fiber and mica, and enclosed within a durable
stainless steel sheath with serrated edges. This design reduces heat loss, improves energy efficiency,
and ensures reliable performance while allowing for easier installation.

Type 2: JIEO’s Heat Saver Ceramic band heater(Double Insulated)

The JIEO’s heat-saver ceramic band heater is based on the standard ceramic band heater’s construction, with two pieces of ceramic fiber insulation on top of a solid stainless steel sheet with serrated edges. This change reduces the energy consumption of heat-saver ceramic band heaters by up to 35% compared to uninsulated band heaters.

Type 3: JIEO’s Vented ceramic band heater

The JIEO’s Vented Ceramic Band Heaters are designed without ceramic fiber insulation and with a stainless steel sheet on the outside. This ceramic band heater is formed by securing ceramic knuckles into a ring with steel wire. This retains its structural rigidity while allowing airflow to reach the ceramic knuckles and the resistance wire, cooling them. The application requires a band heater that can also be air-cooled with a fan; this is a good option for you.

Plus Shroud with Vented Ceramic Band Heater

These shroud designs are made with stainless steel sheet metal construction. The shroud effectively increases airflow over the heating coil, thereby rapidly dissipating heat. This ensures that the heating coil does not overheat during operation, thereby extending its service life. Effective heat dissipation allows for more precise control of the heating coil’s temperature, thereby meeting the strict temperature requirements of production processes. It is suitable for environments with high heat dissipation requirements or good ventilation.

The Shroud should be customized to your machines. The shroud is an independent device and easy to install.
