A vacuum oil quench (VOQ) furnace purchased by Solar Atmospheres of Western PA entered into full production after passing start-up protocol. The initial temperature uniformity survey, compliant to AMS 2750F, produced +/-10°F results at all setpoints. The critical lift-and-place transfer mechanism worked, and the system delivered hot 2,000-pound loads to the internal oil-quench tank. With a quench system that is entirely self-contained and vacuum-tight, the typical positive-pressure “flare and smoke-ups” during each quench cycle were nonexistent. The furnace, which was designed and built by Solar Manufacturing, has a hot zone measuring 36 x 36 x 48 inches.
Ipsen recently installed a vacuum furnace at Temprasud, a commercial heat treater in Fresagrandinaria, Italy. According to Temprasud, the vacuum hardening and low-pressure carburizing furnace will increase its production capacity and offer customers greater flexibility. The furnace, which has a 1,764-pound (800-kg) load capacity, will also help Temprasud grow its business in the automotive market and allow it to expand into the aerospace market.
Pfeiffer Vacuum opened a 40,000-square-foot facility in Indianapolis, Ind., that will serve North American customers in all technological questions around leak detection and high-vacuum technology, focusing on the automotive industry, semiconductor applications, medical devices and consumer electronics. The Leak Detection Center of Excellence includes a CNC machine shop and modular assembly bays to support air and helium leak detection as well as custom-engineered vacuum systems. Customers will be able to have parts tested on Pfeiffer Vacuum leak-detection technologies – such as air, helium and hydrogen test methods – and determine which is best for their application.
SECO/VACUUM, a SECO/WARWICK Group company, received an order for a 2-bar vacuum heat-treating furnace from an automotive components manufacturer. The single-chamber furnace, which has a chamber size of 36 x 36 x 48 inches and a load capacity of 3,300 pounds, will increase the company’s annealing production of fuel-injector components. The high-pressure-quench unit will complement an existing SECO/VACUUM furnace in operation at that location since 2002. Because the new furnace is a nearly identical model, they share standard components and will reduce the necessary inventory of spare parts.
Solar Manufacturing Inc. received an order for a vacuum heat-treating furnace order from a firearms manufacturer based in the United States. The furnace has a hot zone measuring 36 inches x 36 inches x 48 inches with a weight capacity of 5,000 pounds. It has a maximum operating temperature of 2400°F (1315°C) and heats to 2500°F (1371°C) for hot zone bake-out. The furnace design has a temperature uniformity of ±10°F and is AMS 2750-compliant with vacuum levels in the low micron range. For rapid turnaround for work cooling, a 100-HP gas blower is provided for operation at 15 PSIG (2 bar) in nitrogen gas.
Ipsen’s Vacuum Technology Excellence Center received orders for 22 vacuum furnaces during the first quarter of 2022. These orders spanned industries including automotive, additive manufacturing, aerospace, commercial heat treating, and tool and die. The company will design and supply models including large vertical bottom-loading units for aerospace to small vacuum debind and sinter furnaces for additive manufacturing. Other orders included those for Ipsen’s AvaC low-pressure carburizing furnace and high-pressure gas quenching used in conjunction with vacuum compression brazing.
Solar Atmospheres of Western PA (SAWPA) was recently awarded three years merit status for SHARP Accreditation. The Safety and Health Achievement Recognition Program (SHARP) is designed to recognize employees and employers for their effort in establishing and maintaining all elements of an effective safety and health program.
A manufacturer of electronic components with engineering centers and factories worldwide purchased a vacuum tempering furnace from SECO/VACUUM, a SECO/WARWICK Group Company, for one of its plants in Pennsylvania. With a chamber measuring 48 inches x 48 inches x 72 inches, the furnace will be used to anneal copper and steel electrical connectors used in subsequent assemblies. The furnace, which can operate up to 1382°F (750°C), will deliver added capacity to meet increased demand for the company’s products. It includes a turbo-cooling feature designed to improve turnaround time from batch to batch and maximize throughput.
TAV Vacuum Furnaces produced a horizontal vacuum brazing furnace for a global manufacturer. The furnace, which has a maximum temperature of 2462°F (1350°C), was developed to braze plate heat exchangers and tailored to the company’s specific requirements. It has two loading zones, a platform on top for easy maintenance and a soundproof cabinet for vacuum pumps. Seven independently controlled heating zones, together with the wide surfaces of the heating elements, allow for fast and uniform heating ramps and shorter cycles. A graphite thermal chamber placed on supports allows for easy extraction in case of maintenance.
