We are a trusted manufacturer and supplier of Sealed Nozzle Heaters, offering highly durable and efficient heating solutions for industries that demand precision temperature control. Designed with high-quality stainless steel sheathing and advanced insulation technology, these heaters provide leak-proof, uniform, and controlled heating for nozzles used in injection molding, blow molding, extrusion machinery, hot runner systems, and 3D printing.

Unlike standard heaters, the Sealed Nozzle Heater is built with a fully enclosed stainless steel body that prevents resin leakage and protects the heating element from wear, contamination, or corrosion. This design makes it a long-lasting and reliable heating solution, especially in high-demand plastic processing environments.

With their compact, robust build and high-energy efficiency, our Sealed Nozzle Heaters ensure smooth material flow, preventing premature cooling or solidification of plastic raw materials. As a result, industries experience fewer production issues, better product quality, and higher machine efficiency.

Key Features of Sealed Nozzle Heaters

• Leak-Proof Design – Fully sealed body prevents resin or plastic leakage into the heating element.
• High-Temperature Capability – Handles intensive industrial processing without loss of performance.
• Uniform Heat Distribution – Minimizes hot spots and ensures even melting and extrusion.
• Fast Heat-Up & Cool-Down – Saves startup time and reduces production delays.
• Durable Build – Stainless steel sheath resists corrosion, abrasion, and high mechanical stress.
• Precise Temperature Control – Compatible with thermocouples, thermostats, and PID controllers.
• Custom Design Options – Available in multiple sizes, voltages, wattages, diameters, and mounting styles to fit different machine nozzles.
