Induction Heater for Metal Parts Hot Fitting Jointing from China Suppliers & Factory for Gear Shaft Processes
Application scope
Secure press-fit assembly with controlled thermal expansion.
Avoids hammering damage in motors and gearboxes.
Ensures tight interference joints in heavy machinery.
Ideal for stainless steel and alloy parts.
Automotive, aerospace, power generation, and heavy equipment manufacturing.
Configuration and Performance
Controlled temperature ensures optimal expansion for interference fits (e.g., gear shafts, bearings, couplings).
Heats metal parts in seconds, reducing downtime compared to traditional methods (oven/oil bath).
Prevents oxidation, distortion, or surface damage common with flame heating.
Supports low-frequency (LF) for thick parts and high-frequency (HF) for thin-walled components.
Compatible with robotic arms for seamless integration into production lines.
Technical specifications
Main components
The heating power is adjustable from 5 to 200kW, and the frequency range spans from 20kHz to 500kHz. This wide range makes the system highly adaptable for heating metal workpieces of various thicknesses, shapes, and materials.
It is ideal for common metal materials such as carbon steel, alloy steel, stainless steel, copper, and aluminum. Typical applications include gear shaft hot sleeving, bearing and bushing installation, coupling and rotor fitting, and pump or valve component assembly.
The equipment features a high temperature control accuracy of ±2°C with a real-time digital display showing a resolution of 0.1°C. This ensures stable, precise temperature control to guarantee optimal assembly quality.
For maximum safety, the equipment is designed with multiple automated protection functions, including over-current, over-voltage, water shortage, and over-temperature protection, ensuring safe operation for both the equipment and operators.
Yes, it is fully automation-ready and compatible with robotic arms. It utilizes PLC intelligent control, which supports parameter setting, storage, and retrieval, allowing for a seamless and automated heating process.
The equipment requires a three-phase 380V ± 10%, 50/60Hz power supply. For cooling, it utilizes a forced water-cooling system requiring a cooling water pressure of 0.1 - 0.3MPa to ensure long-term stable operation.
