How to Choose the Best Sapphire Glass Manufacturer

Besides knowing the list of the world’s most trusted and recognized sapphire glass suppliers, it’s also important to note and have full understanding of what you need to look for when choosing a manufacturer.

It’s not just about the size of the company or their product-line capabilities, there are other factors you’d want to consider, too!

Check the Company’s Licensing and Certifications

One of the most important things you need to do is to check the licensing and certifications of the company you’re working with. This is going to be proof of how competent, experienced, and knowledgeable they are of the industry.

Some of the certifications and licenses you want to see are:

  • ISO 9001
  • EN 13541
  • EN 1288
  • EN 675

NOTE: Thes aren’t the only certifications you want to see, there are others more that are important an essential in the industry.

Do a Background Check of the Company’s Roots

A little background checking isn’t going to hurt. This is where most people fail. Just because you see a company having mountains of certifications, doesn’t mean that they’re the best in what they do. Try and check previous projects – what have they done? What have they built? How did they become who they are in the industry?

You also want to ensure the quality of their services. No one wants to work with a company that has bad roots, right?

Check the Company’s Availability

The more available and accessible a company is, the better they are. In today’s society, availability is a goldmine. You’ll see many manufacturers not answering for days, even if the question they’re asking is relatively easy to answer.

Work with a company who will respond to you in a blink of an eye. No matter how serious or simple the question is, it’s important for businesses to attend to their clients’ concerns.

Read Reviews and Ask Previous Clients

Another useful tip that experienced businesses do is that they look for reviews or they ask previous clients of their experiences with a manufacturer. Nothing’s better than getting the opinion of someone who arrived before you.

Most companies would display the line of feedback and testimonials they’ve gotten from their clientele. This is to further show and prove that they are reliable and can be trusted.

You can choose to go the extra mile by asking previous clients of their experience. Try locating a previous client and ask about how their experience went when they worked with the company. This gives a better, a more actionable, and a more trustworthy social proof.

Shop Around

Last but most definitely not least is to shop around. Remember, there are tens of thousands of manufacturers in the world, you aren’t just limited to the ones you see first. Try to ask as many quotes and estimates as possible, and compare your way through your decision.

There is an unlimited number of ways you can do this, and it’s important to make sure that you’re getting what you’re supposed to.

It’s imperative to understand that these aren’t foolproof. This worked for the majority of businesses looking to partner with a sapphire glass manufacturer, but that doesn’t mean that it’s guaranteed.
