Induction Melting

Melting with induction provides reliable, repeatable, non-contact, safe and energy-efficient heat in a minimal amount of time. These advantages can be effectively utilized in the metal melting process. Whether your application involves melting of a few grams of metals is small crucibles, or an input of several hundreds of kilograms in latge furnaces, Ambrell provides the best solution.


Popular Melting Application Notes

Click to read how induction heating can improve the efficiency, effectiveness and safety of your melting process.

Melting of Ni based alloy samples Melting of Ni based alloy samples

Induction heating provides hands-free heating, involves no operator skill required for manufacturing, even distribution of heating and fast, controllable temperature ramp

Heating a crucible for melting plasticHeating a crucible for melting plastic

A single-position 6-turn helical coil is used to generate the required heating for application. The crucible is heated in 70 seconds with the 5kW power supply.

Melting silicon in graphite crucible for material testingMelting silicon in graphite crucible for material testing

The customer is developing a university lab experiment to melt silicon and is still developing the process.

Melting lead ingots to form battery posts and connectors Melting lead ingots to form battery posts and connectors

Melting 30 lb(13.6 kg) & 60 lb(27.2 kg) lead ingots to form battery posts & connectors

Melting the end of a plastic tube to create a sealMelting the end of a plastic tube to create a seal

A single turn coil encapsulated in custom blocks is used for sealing the tube. Two tubes are placed between the coil blocks and a 7lb (3.2kg) load is applied to the top of the coil.

Crucible melting a variety of materials in a nitrogen atmosphere Crucible melting a variety of materials in a nitrogen atmosphere

The crucible is heated using a coil with a four turn pancake at the base that extends upward into a three turn helical coil.

Melting aluminum in a graphite crucible for castingMelting aluminum in a graphite crucible for casting

Induction heating provides hands-free heating that involves no operator skill for manufacturing, repeatable, dependable results, more efficient and cost effective then gas furnace, does not heat up the manufacturing area and increases production.

Hermetic sealing of stainless steel rods with glass preformsHermetic sealing of stainless steel rods with glass preforms

Induction heating provides hands-free heating that involves no operator skill for manufacturing, amounts of glass are precisely controlled by the glass preforms and even flow of glass creates aesthetically pleasing bond.

Remove plastic coating from steel tubes Remove plastic coating from steel tubes

Induction heating is the only feasible way to remove the plastic coating, leaving it in an unpolluted form for recycling. It is a faster process

Releasing a Lens Grinding Fixture Bond Releasing a Lens Grinding Fixture Bond

The bonded assembly is placed (glass up) within a helical coil which circles the bonding slug. Induction heats the material to the melting point in 5-7 seconds.

Melting of Ticonium and Nobilium ingotsMelting of Ticonium and Nobilium ingots

Due to the small size of the ingots, RF induction heating was required to efficiently couple to the samples in order to provide the necessary power to initiate melting.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as steel, copper, aluminum, brass or it can be a semiconductor such as carbon, graphite or silicon carbide. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.

As a pioneer in solid-state induction melting technology, with a 30-year history of innovation, Ambrell provides industry-leading heating solutions. Our systems, installed in over 50 countries, are supported by our network of dedicated induction heating experts. With a firm commitment to innovation and continuous improvement, we are proud to deliver quality products and solutions for a variety of industries and markets. 

Together with integrators, Ambrell developed reliable and efficienmt melting systems. These systems operate with Ambrell power supplies ranging from 2.4 kW to 500 kW output power. Ambrell provides induction melting solutions based on melting in crucibles and induction furnaces.

A typical set up for an induction melting application consists of a power supply, workhead, induction coil and a crucible.

Metal melting system utilizing an induction furnace consists of a simple nose tilt-and-pour mechanism that uses an air/hydraulic assist for smooth, effortless pouring. Such system uses a custom-designed heavy duty, high-conductivity coil ensuring the best delivery of the heat to the parts. This system is also powered by Ambrell induction generator. We also provide water cooling systems for melting installations – from closed-loop air-cooled cooling systems for low power induction power supplies to evaporative open-loop cooling towers for higher power induction power supplies.
