Induction heating is a convenient and flexible method to deliver high-strength magnetic fields to nanoparticles, resulting in a focused and targeted treatment that is gaining considerable interest in the medical research community.
Hyperthermia (or thermotherapy) is a type of cancer treatment that involves heating of tumor cells within the body. Even as far back as 3000 B.C., Egyptian pundits used heat baths to burn subcutaneous tumors. Doctors observed that high heat, such as that resulting from a fever, killed cancer cells and decreased tumors.
One of the most common uses for induction heating is the heat staking of threaded metal inserts into plastic. Most thermo-plastics are too soft to sufficiently hold a thread, so brass or steel threaded inserts are added.
For heat staking, the insert is preheated with induction and then pressed into a hole in the plastic part. This is accomplished by positioning the induction coil over the hole and then holding the insert in the coil for a short period of time.
Injection-molded plastic parts are used increasingly in a variety of industries including automotive, office furniture, cutlery, gardening equipment and more, because of their strength and lighter weight when compared to metal.
