Electromagnetic Induction Melting Furnace Electrostatic Painting Line For

Product Specification

Equipment description:

Description of core equipment of automobile aluminum wheel production line ‌
‌ Smelting and casting stage ‌
1. ‌ liquid aluminum smelting equipment ‌
‌ electromagnetic induction melting furnace ‌ : high efficiency melting aluminum ingot (containing silicon, magnesium and other alloys), equipped with degasing refining device (argon impurity removal) to ensure the purity of liquid metal.
‌ low pressure casting machine ‌ : the liquid aluminum is injected into the mold through the pressure, forming the wheel hub blank (mainstream process), the mold life of more than 100,000 times, support multi-cavity synchronous casting.
2, ‌ heat treatment equipment ‌
‌ solution treatment furnace ‌ : the blank is heated to 500°C and then cooled by water to improve the strength of the material.
‌ aging furnace ‌ : Low temperature tempering (150-200°C) stabilizes material microstructure.
2. Technology trends ‌
‌ digital twin ‌ : virtual debugging of production line, process optimization efficiency increased by 30%.
‌ green manufacturing ‌ : smelting waste heat recovery, water-based paint instead of solvent paint (VOC emission reduction of 90%).
‌AI quality inspection ‌ : deep learning to identify defects, missed detection rate < 0.1%.

Main structure and components:

First, mechanical processing
‌‌CNC Machining center ‌
Five-axis linkage machine tool: complete hub and spoke fine milling, bolt hole machining (accuracy ±0.02mm), equipped with automatic tool changing system (20+ tool library).
Turning machine: Processing hub inner diameter, end face and PCD (hole distance circle diameter), compatible with 18-24 inch specifications.
‌ automatic auxiliary equipment ‌
‌ robotic arm ‌ : blank loading and unloading, interprocess transfer (beat ≤30 seconds/piece), integrated visual positioning system.
‌ smart jig ‌ : pneumatic/hydraulic clamping, suitable for different wheel hub shapes.
Two, surface treatment stage ‌
