Radiators or towel rails industry has known an high evolution. At the very beginning, to braze this kind of products, it was common to use silver alloy, very expensive and with no real advantage (removal of flux deposit for example required an extra cleaning bath).
The first AV Saldature innovation was to swap from silver based alloys/flux to brass alloy and flux in the flame with vaporize system, this technology was also easy to apply on the new incoming automatic machine, necessary for such growing market. the second AV Saldature innovation together with the development of the brazing furnace was to suggest the use of copper paste in CAB Furnace, wildly use in automotive component production.
Today, the produce towel rails you can use:
1. Automatic Brazing Machine
| Investment | Medium – High |
|---|---|
| Production | Medium – High |
| Versatility | High |
| Brazing Quality | Good |
The automatic production by dedicated brazing machines cuts the costs for piece if divided on necessary quantity. The investment is not high and gives good versatility about brazing models, the brazed joints have an excellent hydraulic and mechanical quality.
Suggested products are:
| Alloy | SM 23 Spool ST 22 Spool |
|---|---|
| Flux | L88N L89N L90N ECOFLUX® ECOFLUX® 89 ECOFLUX® 88 |
| Device | Vaporizer Mod. N |
2. Handly Brazing
| Investment | Low |
|---|---|
| Production | Low |
| Versatility | High |
| Brazing Quality | Good |
Handly production reduce the machine impact costs to the minimum. It is the most economic solution available on the market, it can be an alternative or an integration to the automatic solution, to be used only if the production does not reach high quantities . The investment is minimum and gives an high versatility about brazing models. The quality of the joints is excellent and has with very good hydraulic and mechanical proprieties.
Suggested products are:
| Alloy | Copper Paste |
|---|---|
| Flux | L88N L89N L90N ECOFLUX® ECOFLUX® 89 ECOFLUX® 88 |
| Device | Vaporizer Mod. N |
3. Brazing Furnace
| Investment | High |
|---|---|
| Production | High |
| Versatility | High |
| Brazing Quality | Good |
Joining radiators by black brazing furnace with copper paste is the best solution when the volume of production is high. The high cost of a furnace leads to an high productivity. The brazed joints have high quality and excellent hydraulic and mechanical proprieties. At the end of the production the towel rail does not need to be clean.
Suggested products are:
| Alloy | Copper Paste |
|---|---|
| Flux | |
| Device | Automatic or Semi-Automatic Despenser |
