A Czech manufacturer of industrial knives, mulching knives and chippers placed an order with SECO/WARWICK for a vacuum furnace with 10-bar high-pressure gas quenching. The furnace, which has been customized to enable the processing of long and straight items, will be used for tool-steel hardening and tempering. SECO/WARWICK engineers designed a nonstandard workspace measuring 600 x 600 x 1,800 mm (23.6 x 23.6 x 71 inches). The modification was implemented to fit the characteristic shape of the workpieces. Apart from the nonstandard dimensions of the chamber, the unit was fitted with a directional cooling option to effectively cool long and thin knives that are prone to distortion during the hardening process.
A manufacturer based in China ordered a horizontal vacuum furnace from SECO/WARWICK. It will help produce highly specialized cast parts used in the aerospace industry. The furnace, which has a graphite chamber and gas quenching system, has a heating zone measuring 59 x 59 x 70 inches (1,500 x 1,500 x 1,800 mm) and can handle loads of precision cast parts up to 6,615 pounds (3,000 kg). The furnace is scheduled for delivery in June.
In April 2020, Reed Miller interviewed Mike McConkey, a dedicated customer-service engineer for Surface Combustion. McConkey, an expert on controlled-atmosphere furnace operation, maintenance and safety, answered some frequently asked questions (FAQs) about the technology and offered some maintenance tips. This article is a condensed and edited version of that interview.
SECO/WARWICK is scheduled to deliver a vacuum furnace to a manufacturer of precision medical devices used in demanding applications. The furnace, which has a heating chamber measuring 600 x 600 x 900 mm (23.5 x 23.5 x 35.5 inches), will be involved in the manufacture of components used in X-ray and radiotherapy equipment. It will be intended for annealing and brazing processes. The Vector includes a high-vacuum system based on a diffusion pump that creates ideal brazing conditions.
Nitrex, a global provider of fully integrated surface-treatment solutions, announced the completion of its Poland plant expansion. The expansion will allow the company to double its current European production capacity for both its Nitrex Turnkey Solutions business unit, including gas nitriding furnaces, and its UPC Marathon software and controls products line. The expansion will also allow Nitrex to manufacture its advanced vacuum heat-treating systems, which were formerly marketed under the G-M Enterprises name. This expansion comes in addition to the company’s existing vacuum-furnace assembly capacity in the United States.

SECO/WARWICK will design and supply a compact vacuum furnace with a heating chamber measuring 400 x 400 x 600 mm (15.75 x 15.75 x 23.6 inches) to Michelin, the largest tire manufacturer in Europe. The furnace will be used for gas hardening in the manufacture of tools for premium tires. It will provide better control over the quality of heat-treated components and reduce the risk of delays. The specialized tools and dies used in the tire production process are mostly treated in vacuum furnaces. Many tire manufacturers engage third-party hardening plants for that purpose, but owning a furnace makes it possible to become independent from third parties.
Ipsen expanded its field-service capabilities to include ultrasonic wall-thickness testing for vacuum furnaces. The test helps customers verify the integrity of their chamber and determine its remaining lifespan. Vacuum chamber wall-thickness testing is a service provided using an ultrasonic inspection instrument. This nondestructive method requires only the removal of a small amount of paint at each desired test point. Ipsen’s service team works with the engineering department to determine the appropriate thickness for each chamber wall and whether it passes or fails to meet the ASME Pressure Vessel Code. When the test concludes, customers receive a detailed report charting the thickness of the chamber wall across a wide range of areas, as well as maintenance and repair recommendations.
