DaWei Induction Heating Co has for years been a trusted supplier of induction heating equipments to numerous automakers in all over the world. We also work with many tier-one suppliers and sub-contractors.
Induction bonding in the automotive industry
Within the automotive industry, induction heating is the primary method of curing or pre-curing adhesives and sealants for closure components such as doors, hoods and trunks. Induction heating is also used to bond parts such as fenders and rear-view mirrors.Every new car model includes an increasing number of bonded joints, making induction an even more important factor in maintaining high quality and production rates. Also, more and more modern materials are being introduced that require bonding. It’s therefore useful to know that induction heating can now be used to cure adhesives in composites-to-metal and carbon fiber-to carbon fiber joints.
Induction brazing in the automotive industry
DaWei Induction Heating Co has a long track record in providing induction brazing solutions for the automotive industry. Here are some of the areas in which we are active:
Induction brazing of aluminum parts for air-conditioning systems, for example evaporator and condenser connections (tube-to-tube, tube-to-block, tube-to-tank)
Induction brazing of steel and copper components, e.g., brake linings, fuel injection pipes
Induction brazing of short-circuit rings for electric motors
Induction hardening in the automotive industry
Few industries have benefited as much from induction hardening technology as the automotive sector. And few—if any—induction companies come close to matching our expertise in this key area.
Working closely with many of the world’s top automakers and auto suppliers, we have to date installed more than 2,000 induction hardening solutions in the following areas:
Induction hardening of engine parts such as valves, crankshafts, camshafts, connection rods and starter rings
Induction hardening of transmission parts, for example CV joints, tulips and axle shafts
Induction hardening of suspension parts such as shock absorber rods, springs and suspension arms
Induction hardening of parts for automatic and manual gear gearboxes, for example rings, selector shafts and sun gears
Induction hardening of clutch springs and brake pads
Induction preheating in the automotive industry
Induction preheating is ideal for reducing the risk of cracking and hardening structures. The reason is that induction generates heat in the material itself, which means that the surrounding temperature is lower than the one generated in the material. This heat is also more accurately controlled than a gas flame. This makes it possible to reduce the temperature difference in the welding zone and achieve a lower cooling rate—particularly important with laser beam welding, where the heat is focused on one single welding point.
What’s more, preheating and welding can occur simultaneously with induction-assisted laser beam welding. You can speed up production without jeopardizing the quality.
Induction postheating in the automotive industry
The automotive industry has traditionally been at the forefront of efforts to slash costs while simultaneously raising quality levels. Little wonder then that automakers and their suppliers have been aggressive adopters of induction technology.
Induction straightening in the automotive industry
Our induction straightening solutions for the automotive industry focus on truck making and repair. Our mobile Minac system is especially suited to the latter, as it allows easy access to hard-to-reach parts, allowing rapid, concentrated heating of damaged profiles and chassis rails.
Induction straightening with DaWei Induction equipment is superior in several key ways to traditional gas flame methods:
Induction heat delivery is accurate; only the workpiece itself is heated
The rapid, accurate heat results in high levels of shrinkage
Induction minimizes the risk of heat damage to surrounding cables, hoses, metals, etc.
Induction is safe, controllable, easy-to-use and environment friendly
Induction tempering in the automotive industry
For years, induction tempering was taboo among potential users. But technical development spearheaded by DaWei Induction—and real-life validation in the automotive industry—have resulted in induction tempering now being a must for a wide range of components.
A vast amount of parts can be treated with induction tempering such as camshafts, crankshafts, drive shafts, torsion bars, couplings, rocker arms, rock drills, chains, suspension arms, clutches, brake discs, steering wheels, CV joints, tulips, shock absorbers, inner and outer races, control rods, valves and output shafts.
Fast, accurate and flexible, induction tempering replaces the huge wasteful furnaces used for decades in heat treatment shops. Fatigue tests have confirmed the quality results delivered by our induction solutions.
