Walshs Glass upgrades with Glaston’s Roller Heat Control (RHC)
In January 2021, Walshs Glass in Western Australia began using their Glaston RHC upgrade, enabling them to improve glass flatness and optical quality. “Today, we’re positioned to take advantage of the rapidly changing glass processing demands in Western Australia,” says Steve Cuff, Executive Operations Manager at Walshs Glass.
Walshs’ first experience with Glaston was with a second-hand HTF furnace from the US that had been decommissioned in 1998. In 2008, the company commissioned a Glaston ProE furnace. The furnace was upgraded in 2019 with iControL software.
“We wanted to give our operators an easier way to use the furnace, and the earlier control system was simply out of date. With iControL, our operators have been able to create their own recipes with the ease of the touchscreen,” Steve says.
After that project went very well, Walshs began to explore ways to enhance the glass flatness and optical quality of the glass from the furnace. The use of soft and hard glass coatings in the market had increased significantly. Steve and his team met numerous times with Glaston to talk – onsite and at industry events.
“The Glaston team was very clear about the results we could achieve,” Steve says. “We’d be better able to meet the high roller wave standards using heat control that could be accomplished with an RHC upgrade.”
Walshs was ready to start the project when the coronavirus pandemic began. Western Australia reacted rapidly by closing all state borders.
“The upgrade was installed on December 28 and was successfully commissioned by January 7, 2021, even while we were experiencing two of the hottest days of the year in Perth with scorching temperatures of +44 °C,” Steve recalls.
“Our maintenance team, outside electricians, and Mukesh worked extremely long 12-hour days. We successfully managed our own customers’ expectations during this period. And in the end, everything went very well.”
“Our customers have commented particularly on our optical quality and glass flatness. Since we are certified to produce soft coated glass by Guardian Oceania, and Saint-Gobain, we now have the measures of flexibility to ensure the best optical output.”

“We purchased the Glaston iControL and scanner upgrade to solve any concern with software or spare parts availability before they became an issue. Once installed, the upgrade helped us win a large glass façade project in Indonesia that required extremely high quality. Both we and Glaston can be proud of the high level of quality achieved,” says Matea Franjić, Chief Operating Officer (COO) of Kristal in Vitez, Bosnia and Herzegovina.Read more
