Using induction heating for bonding accelerates the bond's polymerization by using induction to heat the sections together at temperatures that typically reach 150 to 300°C.
The temperature and duration of heating determines the strength of the bond created. This process is now widely used to manufacture automotive body parts (doors, hoods, tailgates, etc.). Induction can also be used to make metal-polyester bonds.
This technique offers a number of advantages:
• No markings on the part (thereby no visible defects after painting), no need to polish
• Better precision on the surface treated
• Quick startup
• Eliminates corrosion problems caused by welding points
• A 2-in-1 solution that offers two different functions: bonding (gluing) and waterproof seals.
Fives has developed a wide range of startup techniques for the bond polymerization process:
• Complete heating of the bonding area using an inductor that matches the part's profile
• Heating by a separated sections for heating by points where the zones to be polymerized are heated up with small flat magnetic circuit inductors
• Indirect heating by heating up attached ferrite particles.
