Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5–10 million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. Our High Efficiency Electric Heating Rods are engineered specifically for industrial mold and process heating applications, delivering precise, uniform heat distribution to maximize productivity and reduce energy waste. With over two decades of experience in heating element manufacturing, we combine advanced materials and strict quality control to offer you a reliable solution that stands up to the toughest production environments.
These heating rods are designed to be directly inserted into molds, dies, platens, and process equipment, converting electrical energy into heat with exceptional efficiency. The key to their performance lies in the high-quality resistance wire, compacted with magnesium oxide (MgO) insulation, and a robust stainless steel sheath. Whether you need to heat injection molds, extrusion dies, hot runner systems, or industrial ovens, these rods provide rapid heating response and long service life, reducing downtime and maintenance costs.
Key Features & Technical Specifications
- High Watt Density: Achieves fast heat-up times with concentrated power output, ideal for molds requiring high temperature in small spaces.
- Uniform Temperature Profile: Advanced winding and filling techniques ensure even heat distribution along the entire rod length, preventing hot spots and thermal stress.
- Durable Sheath Materials: Available in SS304, SS316, and Incoloy® for excellent corrosion resistance and oxidation resistance in high-temperature environments.
- Customizable Dimensions: Diameters from 6 mm to 30 mm, lengths from 100 mm to 3000 mm, with optional lead wire configurations and terminal types.
- Flexible Voltage & Power Ratings: Designed for single-phase or three-phase AC power (110V–480V), with power ratings tailored to your specific process requirements.
- Integrated Thermocouple Option: Can be supplied with built-in Type J or K thermocouples for precise temperature control and monitoring.
- Cold End Termination: Reduced heat loss at the connection end, protecting wires and improving safety.

Frequently Asked Questions
-
Q: What is the typical lead time for custom heating rods?
A: Standard lead time is 10–15 working days for custom sizes and specifications. Urgent orders may be expedited upon request. -
Q: Can these heating rods be used in corrosive environments?
A: Yes, we offer sheaths in SS316 or Incoloy® for enhanced corrosion resistance in humid or chemical-exposed environments. -
Q: Do you provide thermocouple-integrated rods?
A: Absolutely. We can embed Type J, K, or T thermocouples inside the rod for direct temperature sensing. -
Q: What is the maximum watt density you can achieve?
A: Typically up to 40 W/cm², but this depends on the operating temperature and required lifetime. Lower watt density extends heater life. -
Q: How do I determine the correct wattage for my mold?
A: We recommend consulting our technical team with your mold dimensions, target temperature, and heat-up time. We can calculate the required power. -
Q: Are your heating rods suitable for high-frequency switching?
A: Yes, they are designed for standard industrial controllers, including SSR and SCR drives, with fast response. -
Q: What certifications do your products have?
A: Our products are manufactured under strict quality control. Specific certifications are available upon request depending on the destination market. -
Q: Can I get samples before placing a bulk order?
