As you read this, chances are you are no more than a few feet from a pane of glass. It’s one of those materials that’s in near-constant demand. And as a manufacturer, the speed and accuracy with which you can add safety codes, kitemarks, company logos and other branding elements to your glass is the secret to satisfied clients and healthy profit margins. So what’s the best way to add coding and marking to glass?

Growing panes: is demand for glass on the rise?

What sort of shape is the glass industry in? Well, in terms of economic sentiment and market buoyancy, the construction sector serves as a decent barometer and allows glass producers to anticipate future demand.

It’s currently an uncertain time for the UK construction industry - due to a blend of economic and political uncertainties - but the signs are encouraging. Glenigan predict that despite disruptions, the sector’s rebound is still on track with the value of underlying project starts set to rise 7% in 2022 and by a further 5% in 2023. Meanwhile the Construction Industry Training Board (CITB) anticipate that UK construction output will grow at an average rate of 4.4% over the next four years. This signifies that suppliers of materials used in the industry - such as toughened glass - will need to look at ways to either strengthen their market share, or better manage existing processes to maximise efficiencies and in turn profits.

Laser optimum coding for glass

What type of coding and marking is needed for glass?

What sort of coding and marking is used in the glass industry?

  • BSI kitemarks
  • Batch numbers
  • Traceability codes
  • EN marks
  • Company branding - such as logo and brand name

Essentially the vast majority of glass used in construction and transport will require some degree of coding or marking. Some clients are beginning to request the omission of safety marks, yet this betrays regulation and carries the risk of fines. In short: don’t omit safety marks.

Lasers are the optimum coding technology for glass. Here’s why.

Marking glass while preserving the integrity of the material can be a big challenge. Traditional ink methods result in low-contrast marks, while chemical alternatives are time-consuming and involve consumable costs which can build up over time. Also if the wrong ink is specified this may result in fading or rubbing off over the lifetime of the glass product.

Laser marking however is a globally proven option for adding high-contrast, permanent marks that are unaffected by the toughening process. The ability to print variable data at high speeds is well suited to reducing lead times in busy production environments, while the consumables-free nature of laser coding translates into low operating costs and minimal downtime long term. In fact a high-quality laser coder will run 24/7 with exceptional efficiency.

Beyond the code...

It’s not just the direct application of coding that Domino has supported glass manufacturers with. Domino’s specialist project engineering teams have also created a mobile glass coding table that replaces the need for stickers or sand blasting on your production line. It’s height adjustable, fitted with industry-grade rollers and can be placed at the side of any existing float or roller breakout table. It enables you to move glass with ease, a manual alternative for offline production situations.

Of course, the traceability of your glass is business-critical too. Domino offers specialist software that enables you to keep tabs of every item both during and post-production. Integrating seamlessly with your order entry software and the laser coder, Domino’s traceability solution provides a data record for each sheet/batch that you produce with variable human and machine-readable codes placed consistently on the glass. It makes it easy to match the right sheet to the right frame and track the location of completed batches across your production site and beyond.

Overview of the glass traceability process

Despite being an age-old industry, the demand for toughened glass is resilient and continues to grow. As a leading global provider of innovative coding and marking technology to the glass industry, Domino specialises in easy to maintain, easy to use equipment that provides low total cost of ownership to bring greater cost-efficiency to your operations. You can also benefit from financing options. Find out more about our products for the glass industry.
