Anneal copper tubes; formed tubes & pipes
Induction offers the same result every time, which makes it ideal for a high volume process such as this one. The previous oxidation issue forced them to polish the handles which added a step in their manufacturing process.
Annealing a stainless steel handle
The client wants to anneal a stainless steel tube while avoiding oxidation. 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.
Annealing brass ammunition casings
The ammunition industry has been annealing cartridge casings the same way since the start of WWII by utilizing large inefficient open gas flame or conveyor-oven style processing. These methods are highly inefficient, require large amounts of floor space, lack consistency, create excess inventory carry costs, and don’t permit in-process inspections. Induction heating does not use pans, torches, revolving wheels or conveyor type ovens. Each and every case is annealed to exacting specifications, reducing variation and damage typically found in mass annealing processes.
Annealing stainless steel tubes
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.
Annealing a copper wire connector (crimp)
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...
Annealing steel wire for a medical application
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
Annealing stainless steel caps for a dental application
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...
Annealing of stellite tips on saw blades
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...
Continuous annealing of copper wire
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....
Annealing lip on cryogenic dewar
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...
Annealing the end of steel wire on a woven wire mesh
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.
Annealing bolt shafts
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.
Annealing Lock Nuts
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
Anneal the end of metal stamp sets
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.
Annealing Tungsten Rods
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.
Band annealing on Titanium fasteners
Induction heating can be incorporated easily with pick and place robotics, delivers a flameless process in which heating is limited to the specific area.
Annealing Brazing Wire
Induction heating provides higher productivity of 27' (8.2m) per minute, a reduction in surface oxidation & scaling with consistent, repeatable results
Achieving Uniform Hardness on Saw Blades
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.
