Brazing Company with Expertise and State Of The Art Equipment
Automatic Machine Products has been creating the highest quality brazed assemblies for well over 80 years and has brazing furnaces to accommodate a wide variety of brazing projects. Automatic Machine Products’ furnace brazing offers a more economic solution with repeatable results due to the higher throughput and consistent heating and cooling process. Automatic will provide a more durable, leak-proof quality part for a variety of industries, ranging from Automotive, Aerospace, Refrigeration/HVAC, Agriculture, Military & Defense, Heavy Equipment, Medical and Energy.
Furnace Brazing Services and Continuous Belt Furnace Brazing
Furnace brazing typically refers to the vacuum furnace batch-type brazing process. This involves a large “oven” where entire batches of parts are loaded into the furnace at one time. The furnace door is then closed, and the furnace is evacuated of all air then heated to the desired brazing temperature. After the braze is complete the batch is then cooled so that the furnace can be reloaded with new parts and the process repeated. As you would expect, this type of process is time and energy-intensive and is only justified when the base materials are extremely reactive to oxygen, resulting in an oxide layer that will prevent a successful braze.
Continuous belt furnace brazing refers to open-ended furnaces that have a belt which continuously cycles through the heat and cooling zones and then returns to the loading area to receive a new load of parts to be brazed. With this style of furnace, parts can be loaded and unloaded indefinitely until the entire order is complete. Although continuous furnaces do not operate in a vacuum, the gaseous atmospheres fed into them replace the oxygen with certain types of non-reactive gases in order to prevent oxidation of the heated components. This is what is referred to as an atmosphere controlled continuous belt-fed brazing furnace. Continuous belt-fed furnaces are a much more cost-effective option if the materials can be brazed outside of vacuum.
What kind of atmosphere does my brazing project require?
Inert atmospheres of Hydrogen and Dissociated Amomnia are two common and cost-effective choices to reduce or eliminate oxidation during the brazing process, as well as producing a clean and bright finished product. Inert atmospheres are required to reduce or eliminate common brazing problems such as oxidation, scaling and Carbon buildup (soot).
Dissociated Ammonia is a mixture of Hydrogen and Nitrogen, which is usually created by thermal cracking of Ammonia in a gas generator. It is especially suited for copper and brass in order to remove oxidation of the joint without the use of flux.
Exothermic Hydrogen atmospheres reduce surface oxides particularly on steel in order to improve the wetting properties of the material surface, creating better flow of the filler material.
Automatic Machine Products’ brazing lines employ fully automated atmosphere generators with continuous gas quality monitoring and a refrigerated gas drying system for consistent, repeatable results. Our knowledgable engineers will analyze your brazing requirements and recommend the appropriate brazing environment for your project.
Why Choose Automatic Machine Products For Your Brazing Projects?
Our knowledgeable engineers will work to your specifications or help you determine the best specifications for your product.
We will recommend the proper gap between components to be brazed, which is critical in creating the highest joint strength. Our technicians have the experience to specify the proper gap between mating parts, and knowing the proper heating ramp and cooling details in order to create the ideal braze conditions, and best results.
We use state-of-the-art computer-controlled gas generating equipment and implement tight controls on gas flow to ensure the quality of the braze. We use refrigerated gas drying systems to create ideal dew points for optimal brazing conditions.
Our technicians are experienced in working with a variety of metals for your brazing and heat treating requirements.
We are well versed in and excel at, complex assemblies consisting of multiple materials in a single brazed assembly.
Our lead times are typically better than most because we’re running our brazing furnaces daily for our own production needs.
We offer full ISO 9001-2015 quality assurance, including the capability to test brazing for strength and leak integrity. We use mass spectrometers that automatically can detect even the smallest of leaks.
