How to Choose the Best Optical Glass Manufacturer

Increasing your chances of finding success in looking for an optical glass manufacturer is high, if you follow these tips!

Prioritize Experience and Expertise

Glassmaking is an art that doesn’t only require skill, but also experience and a spoonful of creativity. The manufacturer you’ll be choosing should not only have broad industry knowledge, but should also be well versed and experienced with the specific glass type you’re looking for.

Whether it’s standard soda-lime glass, optical glass, chemically-strengthened glass or whatever glass type you need, the manufacturer should be the best at it in terms of the complexities, nuances, and challenges of the specific type.

As much as you can, avoid working with beginner suppliers as it can impose bad results, which may look negative on the side of production.

Gather as Much Quotes as You Can!

At the end of the day, there will always be a superior manufacturer even if their offers look, feel, and seem the same. You can beat this challenge up by getting a plethora of quotations and estimates from the suppliers you come across.

A single bid is enough to get you going, but by shopping around, you’ll open new possibilities and opportunities you never knew was possible.

It has been a rule of thumb to gather many quotations to see what will fit best for the application and the business you have.

The Cheapest Isn’t Always the Best

We know how important and crucial price is, but going for the lowest quotation or estimate is a recipe for disaster. This has been one of the most common mistakes businesses make because of their desire to spend less and get more.

Think about it, why would some manufacturers offer ridiculously low prices? – Because their product quality isn’t guaranteed. Moreover, some manufacturers also misdirect their bids and estimates, saying that there aren’t any added things, when, in reality, there is!

Be sure to take not of the following to avoid problems:

  • Ask about the shipping and the delivery of the orders
  • Inquire if their service already includes installation/consultation/after-sales services
  • Double-check what the quotation calculates up to, have it in writing
  • Inquire about possible price changes

Have Clear Communication

Communication is key, especially if you are going to work with an optical glass manufacturer. From the level of detail that’s needed to achieve the goals and designs you want to the inspection and control quality; you want everything to be as sharp and crisp from the moment you talk about the deal until the time it’s closed and finished.

Clear and constant communication are two key features of a successful transaction. You want to make sure that:

  • You’re able to communicate what you want and what you’re looking for
  • The lead time and the schedules are set properly
  • The plan is laid out correctly

Ask Questions

Another thing you need to make sure of is that you ask many questions from the manufacturer. Be as annoying as you can, but it’s going to work to your advantage.

Ask them questions that would open up more things and opportunities for you, like how much production they can manage per day, how well they’re able to manage orders, how they communicate with their clients, and so on.

You want to squeeze out everything you can from them so you become comfortable with who you’ll be working with.

Look For Feedback

And last but most definitely not least is to ask previous clients about their experiences with the manufacturer. Most manufacturers, if not all, would publicly display the testimonials and feedback given by their previous clients.

Moreover, the contact information would be visible there, too. You can either rely on the feedback that the manufacturer displayed (which can be controlled), or you can contact and ask about them directly.

Personally, I find the feedback part the best and most rewarding of all, because you get firsthand experience from a business that they worked with. Although, this may be inaccurate because of how the capability of the manufacturer changes over time.
