Induction offers the same result every time, copper tubes of various geometries heated to temperature in a matter of seconds, which makes it ideal for a high volume process such as this one.
Induction offers the same brass annealing results every time, while a torch often delivers variation and there is no open flame with induction.
The client's parts were heated to the desired temperature in less than three seconds. Their gas oven required twice as much heating time as the induction process. Induction is more energy-efficient and requires less space compared to a gas oven.
Looking to replace an inefficient oven process, part is heated in just 30 seconds, improving efficiency for this application
The client wanted to be able to heat parts of various sizes, which was achieved with a concentrator coil. This is a new process for the client, and Ambrell's lab expertise proved very valuable when creating the process...
The wire achieved the targeted temperature within three seconds. By bringing their process in-house, the client will have better control over the end product. Ambrell was able to perform a free laboratory test and design a process that could enable the client to bring the process in-house in a cost efficient manner, and even connect them with an automation partner to maximize productivity
Requirement to anneal large quantities of work-hardened crowns suggests induction for precise, controllable heating. Since oxidation is unacceptable in the finished product, Induction is the appropriate choice for heating in an inert atmosphere...
To anneal the brass tubes, a twelve-turn helical coil is used to heat an 8 (20.3cm) area 3 (7.6cm) above the end of the tubes. Each of the four tubes require a different heat cycle and time to reach the required temperature.
A fourteen-turn coil is used to heat 3.9 (100mm) of zinc wire. The wire is placed in the coil for 5 seconds to reach the desired condition just prior to the forming process...
A three-turn helical coil is used for annealing the motor shaft. The end of the motor shaft is placed in the coil and power is applied for 20 seconds to reach 1350 °F (732 °C) and turn the steel red hot...
An eight turn helical is used to heat the tube for annealing. To anneal the full length of the tube, the tube is placed in the coil and heated...
A split four turn helical coil is used so the blade can move evenly though the coil. Each tip of the blade is heated for 5 seconds as it passes through the coil to anneal the affected area...
A twelve turn helical coil is used. A ceramic tube is placed inside the coil to isolate the copper wire from the copper coil and to allow the copper wire to flow smoothly through the coil. Power runs continuously to anneal at a rate of 16.4 yds (15m) per minute....
A two turn helical coil is used to heat the lip on the cryogenic dewar. The dewar is placed in the coil and power is applied for 2 minutes to anneal the required 1 heat zone...
A single turn helical coil is used on the 4 (101.6mm) diameter tubes and a two turn helical coil is used on the smaller diameters.
Induction heating provides faster production process, high efficiency, low energy costs compared to gas furnace, fast, controllable process and hands-free heating that involves no operator skill for manufacturing.
Induction heating provides controlled application of heat to very specific area, faster process time, increased production and high efficiency, low energy cost.
Annealing brass with induction provides hands-free heating that involves no operator skill, pinpoint accuracy and consistent results
Flameless induction heating allows formerly batch process to be done in-line saving time and energy. No rotation of part needed.
A three turn helical coil is used to heat the shaft of the bolts for 10 to 12 seconds on the large bolts and 18 to 20 seconds on the smaller bolts using the same coil.
A three turn helical coil is used to heat the locknut to 2150°F for 5 seconds. Induction heating provides repeatable, rapid and accurate heating cycles making it ideal for in-line production processes
One five-turn and two four-turn helical coils are used to heat the end of stamps to the required temperature. Two part sizes can be run in each of coils, using the same machine settings except for cycle time.
Induction heating provides improved quality of blades at hole punching location, decreased scrap product and is easily incorporated into existing production lines
A multi turn induction heating coil is designed for heating the various rod diameters. An optical pyrometer is used to measure the temperature of the part inside the induction coil.
Induction heating can be incorporated easily with pick and place robotics, delivers a flameless process in which heating is limited to the specific area.
Induction heating provides higher productivity of 27' (8.2m) per minute, a reduction in surface oxidation & scaling with consistent, repeatable results
To selectively and uniformly anneal two sections of a thread ring gage block from the hole to the outside surface from a hardness of Rc 59-61 to Rc 45.
Resulting mean hardness of 50.3 Rc was measured for fifteen saw teeth on a Wilson Superficial Hardness Tester, fulfilling the ultimate goal established by the customer.
