HVAC, Appliances & Electrotechnical

Induction heating is widely used in automotive manufacturing for metal part heating, joining and heat treatment. It provides fast heating, precise control and repeatable results for vehicle components.

KEXIN induction heating machines can be used for gears, shafts, bearings, fasteners, brake parts, transmission parts and electric vehicle components.

Introduction

Manufacturers of HVAC equipment, household appliances and electrical products require highly controlled heating processes to ensure reliable joints, long product life and efficient production. Induction heating provides localized, non-contact heating with excellent temperature control, making it ideal for high-volume manufacturing.

Compared with flame or furnace heating, induction heating offers faster cycle times, reduced oxidation, improved consistency and seamless integration into automated production lines. It is widely used in air conditioning systems, refrigerators, washing machines, water heaters, electric motors, transformers and electrical assemblies.
