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

What are the primary applications of electromagnetic induction heaters?

Electromagnetic induction heaters are commonly used in industrial heating, metal processing, plastic extrusion, and injection molding machinery to provide rapid, contact-free, and energy-efficient heating.

Can flexible heaters be designed for custom shapes and sizes?

Yes, flexible heaters are specifically engineered to conform to curved, irregular, or uniquely contoured surfaces across medical, aerospace, and electronics industries.

What makes high density heating elements different from standard elements?

High density heating elements deliver superior watt density, enabling higher operating temperatures and compact designs without sacrificing service life or thermal conductivity.

How energy-efficient are infrared ceramic heaters?

Infrared ceramic heaters convert a vast majority of input energy into radiant heat, warming objects directly without heating the surrounding air, leading to notable energy conservation.

What are the main advantages of safe and durable mica heaters?

Mica heaters provide excellent dielectric strength, high temperature resistance, and fast heat transfer, making them dependable for cylindrical surfaces like pipes and injection barrels.
