1. Introduce
SK Brazing Company has built serveral types of gas heating coil brazing machines for brazing u-bends of copper heat exchangers and aluminum heat exchangers. 

In particular, SK Brazing Company has designed a very special aluminum coil brazing machine that makes it possible to avoid the orange peel crack phenomenon and erosion issues commonly found on brazing of aluminum u-bend coils. Our technology sets a new standard in aluminum brazing technology.We have built several types of gas flame brazing and soldering machines for joining of u-bends for heat exchangers. These include a slat conveyor type and a free flow pallet conveyor type. These machine have three stage flame control and memory storage of flame strength, conveyor speed, burner height, burner width and degrease options. Also we can incorporate bar code reading capability upon your request.

In addition, we offer a coil-to-header brazing machine, manual brazing equipment like the Torch Man(a hand-held, intelligent, personal digital torch kit), manual induction brazing equipment and many more types...)

2. Coil brazing machine types
1) Torches move up/down type with fixed slat conveyor
- Conveyor height is ficed with torched moving up/down for each model.

2) Conveyor up/down position memory type/torch height fixed type coil brazing machines
- Coveyor unit move up/down with torch height fixed.

3) In-line free flow conveyor type coil brazing machines
- Pallets moving with in-line free flow conveyor unit .

4) Square movement conveyor type coil brazing machines
- Continuous movement of Pallets in a square pattern, combining with auto loading/unloading equipment, brazing booth, cooling booth & dry oven.

5) Dry oven

SK Brazing manufactures various dry ovens to remove oil, which is an essential process for all U-bend brazing processes. There are two types of horizontal coils and one vertical coil.

6) Index type ultrasonic dip coil brazing machines
- SK Brazing has built many index brazing/soldering machines. A special machine is shown below, with coil u-bends joined in a molten zinc alloy bath by ultrasonic evergy without flux.

3. SK Brazing coil brazing machine characteristics 

For your reference, many SK Brazing coil machines are being copied by others throughout the world, but they can not imitate all of SK Brazing’s original technology. SK Brazing sells coil brazing machines and brazing technology, and provides various technical services for brazing machines for cost reduction, leak prevention and permanent durability.
