Can Kangpu manufacture industrial heaters to my own drawing?

Yes. Customization is our core service. Send a drawing, a sample or the machine model, and our engineers will confirm dimensions, voltage, wattage, clamping method, terminal and lead style, then build a sample for your approval before mass production.

What warranty comes with Kangpu heaters?

Kangpu provides a five-year after-sales warranty. Every warranty case is traced back to its production batch so the root cause can be corrected, not only the part replaced.

How does the sampling and approval process work?

We follow seven stages: ID design, product customization, real-mold sample making, customer sample confirmation, sample modification, sample testing and mass production. Mass production starts only after you approve the tested sample.

Should I choose a ceramic band heater or a mica band heater?

Mica band heaters are compact, respond quickly and cost less, which suits injection nozzles and moderate temperatures. Ceramic band heaters use insulating ceramic blocks that keep heat in and tolerate higher process temperatures, which suits extruder barrels and energy-sensitive lines. Share your process temperature and barrel size and we will recommend the right construction.

Which countries does Kangpu export to?

Kangpu heaters are exported to more than 100 countries and serve over 5,000 customers, mainly plastics machinery builders, extrusion and injection molding plants, pipe producers and process-heating integrators.

Frequently Asked Questions

Q: What applications are explosion-proof electric heaters suitable for?

Explosion-proof electric heaters are specifically engineered for hazardous environments where flammable gases, vapors, or dust may be present, such as chemical plants, oil refineries, and offshore platforms.

Q: How do hot-runner coil heaters optimize production efficiency?

Hot-runner coil heaters deliver fast, uniform heat distribution directly to the nozzles, minimizing cycle times and reducing material degradation in precision injection molding processes.

Q: What are the key benefits of ceramic infrared heaters?

Infrared ceramic heaters offer high thermal efficiency, long operating lifespans, and deep, non-contact radiant heating ideal for thermoforming, drying, and curing applications.

Q: Why choose an integrated heating and cooling system?

An integrated heating and cooling system combines precise thermal control within a single compact unit, ensuring tight temperature tolerances and improved energy management for sensitive industrial processes.

Q: When should cast aluminum or copper heaters be selected?

Cast aluminum and copper heaters provide rugged durability, superior thermal conductivity, and excellent contamination resistance, making them ideal for plastic extruders, dies, and laminating equipment.
