Whether it be our bodies or our favorite objects, we all know that if we want to keep anything working well for a long period of time, we need to keep up with routine maintenance. Not only will it keep everything intact, but it will also continue to work hard for you. When it comes to vacuum furnaces, the same thing holds true. Having a well-designed preventative maintenance program in place will ensure everything runs smoothly and protect your investment.

Upon purchase of the vacuum furnace, read the manual. It help with future troubleshooting, and also give you an indication of what regular maintenance will entail down the road. Obviously, cleaning, part replacement and lubrication is necessary, but also performing leak checking of the machine and repairs as needed. The more you know about your machine, the easier it will be to detect when things are beginning to go wrong. Keep good records – parts, maintenance checklists of all the components that makes the furnace run smoothly.

Here at GM Enterprises, we offer a wide array of services for our vacuum furnaces to our clients. Not only does our expertise involve training and technical support programs to help you learn your machine, but we also provide installation, repairs and replacement parts.

Investing in a vacuum furnace is a big investment, and one that needs to last for a long while. But everything needs a bit of tender loving care from time to time in order to continue to do its job. Taking the time to learn the ins and outs of it will make this investment one that will service you for years to come.

When the time comes to purchase a new industrial furnace, there are several points that need to be considered beforehand. Like, the operating temperature that will be used most often. Because, despite what many may think, it isn’t “one size fits all”. The following are a few of the common things one should consider when preparing to purchase an industrial furnace:

Temperature ranges. It is important to know what temperature you will need for your typical project, in addition to future projects you may have.

Future considerations. Because you can’t always use one furnace for all of your projects, you may want to consider a larger unit with respect to issues of maintenance, reliability, and temperature uniformity as compared to a higher temperature unit.

Furnace geometry. The box unit is great for loading samples in a batch operation, while a tube unit is generally better for a continuous application.

Uniformity. Many options are available ranging from the introduction of cooled gases, to vents, fans, or a combination, to achieve a controlled cool-down cycle.

Controls. Will a standard single set point temperature controller work, or will a programmable unit be required? Making sure you know what you’re looking for will narrow in your options.

Atmosphere. Another consideration should be the atmosphere that will be used in the unit, as this can have a significant bearing on purchase and maintenance costs.

Customization. The final item to be considered – cosmetic issues. Standard products are available from most vendors of lab furnaces, while some manufacturers offer standard units as well as fully customized units that can be specified and engineered to exact customer requirements.

G-M Enterprises supplied a 20-bar vacuum furnace to Paulo Products Co. The furnace, which has an 8,000-pound load capacity and maximum work-zone dimensions of 48 inches wide x 36 inches high x 60 inches long, was installed at Paulo’s St. Louis, Mo., facility. The furnace is equipped with an 800-hp cooling motor, graphite hot zones and an Allen Bradley PLC control system. Thanks to this new furnace, Paulo-St. Louis can now handle larger parts requiring vacuum heat treatment. The facility has already successfully completed all necessary testing and has received approval as a provisional heat-treat source of Die Insert Material for Ford Motor Co. and General Motors, Powertrain Division.
