PRODUCT APPLICATIONS

Induction Hardening of Engineering Machinery Parts

Induction hardening is a widely used surface heat treatment process that enhances the durability and wear resistance of engineering machinery parts. By using electromagnetic induction to heat the surface of metal components, followed by rapid cooling (quenching), this method creates a hardened layer that significantly improves fatigue strength and performance under heavy-duty conditions.

PRODUCT APPLICATIONS

Induction Hardening for Automotive Parts

Induction hardening is a highly efficient heat treatment process widely used in the automotive industry to improve the durability and performance of critical components. By rapidly heating and then quenching the surface of metal parts, induction hardening increases hardness, wear resistance, and fatigue strength without affecting the core properties of the material.

PRODUCT APPLICATIONS

Induction Hardening of Tractor Parts

Induction hardening is a heat treatment process widely used to enhance the surface hardness and wear resistance of steel components. In the agricultural industry, particularly in tractors, this technique plays a critical role in extending the lifespan and performance of key parts subjected to high stress and friction. Components such as gears, axles, shafts, and pins benefit significantly from induction hardening, ensuring better durability and reliability in demanding field conditions.

PRODUCT APPLICATIONS

Motorcycle Parts Induction Hardening

Induction hardening is a critical heat treatment process used to enhance the durability and wear resistance of motorcycle parts. By applying high-frequency electromagnetic fields to heat the surface of metal components, followed by rapid quenching, induction hardening creates a hardened outer layer while maintaining a tough and flexible core.

PROCESS INTRODUCTION

Induction Hardening Process

01
Part Loading & Fixturing

Automated Feeding: Parts are loaded via robots, conveyors, or vibratory feeders.Precision Fixturing: CNC-controlled clamps or chucks position the part accurately for hardening.Barcode/RFID Tracking: Ensures correct process parameters for each part type.
02
Induction Heating Stage

High-Frequency Power Supply (3–400 kHz) delivers controlled energy to the induction coil.Coil Design: Custom-shaped copper coils (single-turn, multi-turn, or scanner-type) heat specific zones (e.g., gear teeth, bearing races).Skin Effect Heating: The part surface reaches austenitizing temperature (750–1000°C) in 2–10 seconds.Temperature Monitoring: Infrared pyrometers ensure consistent heating before quenching.
03
Immediate Quenching

Integrated Quench System activates within <1 second after heating:Spray Quenching: High-pressure nozzles apply water, polymer, or oil.Immersion Quenching: Parts are lowered into a quench tank (for large components).Quench Delay Control: Critical for preventing soft spots or cracking.
04
Tempering (Optional In-Line Process)

Induction or Convection Tempering reduces brittleness while retaining hardness.Low-Temperature Heating (~150–400°C) followed by air cooling.
05
Unloading & Post-Process Inspection

Robotic Unloading: Hardened parts are transferred to cooling racks or packaging.Automated Quality Checks:Hardness Testing (Rockwell, Brinell).Dimensional Verification (laser scanners, CMM).Crack Detection (magnetic particle or ultrasonic testing).
06
Data Logging & Process Control

PLC/HMI System records:Heating time, temperature, power.Quench flow rate, cooling time.Hardness results for traceability.Industry 4.0 Integration: Connects to MES/ERP for real-time analytics.
