Selection of a supplier of industrial furnaces

Industrial furnaces are critical equipment in many manufacturing processes. Manufacturers use them to decontaminate medical devices and instruments, sterilize lab equipment, burn excess chemicals from pills, and burn test materials. In addition, they are used for aging, tempering, annealing and treating metal. The key is finding the right industrial furnace for your application. But first you need to choose the right supplier of your oven supplier. That’s easier said than done.

Below are some important steps to take when finding the right industrial furnace supplier for your applications:

1. Create a checklist of oven manufacturers

One of the most critical steps in finding a supplier is creating a general list of industrial furnace manufacturers. The list of companies above can help you get started. Go through the companies on your list one by one to create a shortlist. Ultimately, you’ll want to narrow down your shortlist to a few companies before deciding which one is right for you. A systematic approach to supplier selection pays off.

2. Check the company’s reputation in the market

Checking the supplier’s reputation in the market will give you a different perspective on the company. If they have worked with companies you have contact with, check with them about their experience with that company’s products. You can also get information from the editors of leading professional magazines. They often have control over who’s who in the industry.

3. Verify the experience and expertise of each company

Before evaluating companies, you should create a checklist of what you want to see in an industrial supplier. Experience and expertise are critical. Look for a supplier with deep experience and expertise in your industry and your type of application. You also want a supplier with deep experience and expertise in manufacturing furnaces for your specifications, requirements and applications. Before reviewing vendors, it’s a good idea to know the exact specifications of your application and production environment.

4. Review quality control procedures and processes

Also look at the company’s quality control procedures.

  • Do they follow critical safety and quality control guidelines?
  • If you need an oven for healthcare applications, do they meet standards like ISO 9001, ISO 13485 and ISO 14001?
  • Do their furnaces provide the uniform and repeatable heat treatment required for critical operation?
  • Do their ovens deliver consistent, uniform, repeatable temperatures?
  • Do they provide the gradual ramp-up speeds necessary for your processing needs?

5. Review the company’s manufacturing capabilities

Additionally, check out their manufacturing capabilities to see how much care they put into furnace manufacturing, such as CAD/CAM and state-of-the-art modeling software. Do the company’s products have a reputation for exceeding process requirements for even the most demanding customer needs? Do they provide installation and training? What about service and warranty programs, parts and repairs? How is its technical support? Does the company provide troubleshooting tips and tutorials to help you solve common problems? Do they offer part trial runs to determine the best heat source and heating system for your product?

These are just some of the considerations you will face when choosing a supplier for your industrial furnace.

Finding the right manufacturer for your industrial furnace is essential. The search should never be rushed or overlooked. When you’re finally ready for a manufacturer and excited to start turning your ideas into physical form, it can be easy to rush into production before properly vetting the manufacturer first. Resist the temptation. Instead, take some time to do your due diligence.

Types of heat treatment

Manufacturers use industrial furnaces to apply heat to a material to produce a desired condition or property. So a critical step in choosing an industrial furnace is defining the heat treatment requirements of your application. The three critical steps of heat treatment include:

Heating the material to a certain temperature

Material cooling based on prescribed methods (optional)

Industrial furnaces heat materials to temperatures below 1000°F (537.78°C). Industrial furnaces heat materials to temperatures above 1000°F. (537.78 °C). Expedition also provides industrial cleaning systems.
