Choosing an Industrial Oven Supplier

Industrial ovens are critical equipment in many manufacturing processes. Manufacturers use them to decontaminate medical devices and instruments, sterilize laboratory equipment, burn off excess chemicals from pills, and burn-in testing materials. Plus, they use them to age, temper, anneal, and treat metal. The key is finding the right industrial oven for your application. But first, you need to choose the right supplier for your oven supplier. That’s easier said than done.

Below are some critical steps to take in finding the right industrial oven supplier for your applications:

1. Create a checklist of oven manufacturers

One of the most critical steps in finding a supplier is to create a general list of industrial oven manufacturers. The list of companies above can get you started. Review the companies on your list one by one to create a shortlist. Eventually, you’ll want to narrow your shortlist down to a couple of companies before deciding which is suitable for you. Taking a systematic approach to choosing a supplier pays off. 

2. Check a company’s reputation in the marketplace.

Checking the supplier’s reputation in the marketplace gives you another view of the company. What are they known for in the industry—technical expertise, product quality, customer service? If they’ve worked with companies where you have a contact, check with him or her to see what their experience was with the company’s products. You may also want to check with the editors of the leading trade magazines. They often have a handle on who’s who in an industry.

3. Check each company’s experience and expertise

You should create a checklist of what you want to see in an industrial supplier before reviewing companies. Experience and expertise are critical. Look for suppliers with in-depth experience and expertise in your industry and with your type of application. You also want a supplier with in-depth experience and expertise producing ovens for your specifications, requirements, and applications. Knowing the exact specifications of your application and production environment is a good idea before reviewing suppliers.

4. Review QC Procedures and Processes

Also, look at a company’s quality control procedures. Do they follow critical safety and QC guidelines? If you need an oven for medical device applications, do they meet standards like ISO 9001, ISO 13485, and ISO 14001? Do their ovens deliver uniform and repeatable thermal processing required for critical operation? Do their ovens deliver invariable, uniform, repeatable temperatures? Do they provide the gradual ramp rates essential to your processing needs?

5. Review the company’s manufacturing capabilities

In addition, check their manufacturing capabilities to gauge what care they put into producing ovens, like CAD/CAM and state-of-the-art modeling software. Do the company’s products have the reputation of exceeding process requirements for even the most exacting customer needs? Do they provide installation and training? How about service and warranty programs, parts and repair? How is its technical support? Does the company provide troubleshooting tips and tutorials to help resolve common problems? Do they offer trial runs for parts to determine the best thermal source and heating system for your product?

These are just some of the considerations you’ll be wrestling with when choosing a supplier for your industrial oven.

Finding the right manufacturer for your industrial oven is essential. The search should never be rushed or overlooked. When you’re finally manufacturer-ready and excited to start bringing your ideas into physical form, it can be easy to hurry to production before properly vetting manufacturers first. Resist that temptation. Instead, take some time to do your due diligence. It will pay off in the long run.
