Glaston reached a significant milestone by delivering its 1,500th Unit’Assembler IG assembly machine to AGC Glass Europe in the Czech Republic. The ZPG‑V machine will produce IGUs for fire‑resistant glass. The Unit’Assembler is known for precise alignment, continuous gas‑fill monitoring, and the ability to handle triple IGUs with the same cycle time as double units. Its working height of 3.30 m and length of 5.00 m make it a flexible choice for high‑mix production.

Schollglas Installs 96‑Meter Jumbo Line with ForelGerman processor Schollglas Group commissioned a 96‑meter “High Tech Jumbo” IG line at its Nossen plant. The system features two thermoplastic applicators in series, allowing seamless switching between different spacer materials without production loss. Forel’s integrated Production Buffer with Auto Alignment ensures stability and precision for spacer widths >20 mm. The AP HT tandem press handles offset IGUs up to 100 mm and processes triple, quadruple, and shaped units with argon or krypton filling.

World’s First 8 × 3.3 m TPA Line in China

Chongzheng Shengda Glass installed the world’s first 8 × 3.3 m insulating glass line with thermoplastic spacer (TPA) from LiSEC. This fully automatic system eliminates conventional spacer bending and assembly, offering seamless size changes, zero changeover time, and up to 30% energy savings. It represents a leap forward for large‑format TPS/TPA production.

Glaston’s New Tech at China Glass 2026

At China Glass 2026, Glaston showcased ULTRA TPS® for thin triple/quadruple IGUs with center glass down to 0.5 mm, the TC Series tempering furnace with Chinook convection for faster cycles, and a carbon‑fibre impeller upgrade for quench blowers that reduces cooling energy consumption by up to 20%.

Key Technology Trends Reshaping IG Equipment

Automation & Smart Manufacturing

Automation is the biggest trend. Traditionally, IG assembly was a bottleneck requiring heavy manual labour—often more than 70% of total production staff. New fully automatic lines integrate washing, spacer application, pressing, gas filling, and sealing in one continuous process, drastically cutting labour costs.

Beijing Hanjiang, in partnership with Schneider Electric, has developed an MES‑driven “digital factory manager” that receives ERP orders, communicates with PLCs, and enables full traceability. Operators simply load glass and press “start”; the intelligent system does the rest. This reduces human error and improves consistency.

Thermoplastic Spacer (TPS/TPA) Technology

Thermoplastic spacer systems are replacing rigid spacers in many applications. They apply spacer material directly onto the glass, eliminating the need for bending, connectors, and inventory of different profiles. Benefits include:

Seamless production – no changeover time for different widths or shapes

High precision – no visible joints or height deviations

Permanent sealing – chemically stable bond with glass and sealant

Energy savings – up to 30% lower energy consumption vs. conventional methods

Glaston’s TPS® is installed in over 200 facilities worldwide; the new TPS® PRO offers even higher flexibility and efficiency. LiSEC’s TPA system further extends these advantages to jumbo formats.

Energy Efficiency & Sustainability

With rising energy costs and environmental regulations, equipment buyers prioritise low‑consumption solutions. Modern furnaces use convection systems (e.g., Glaston Chinook) to shorten cycles, while intelligent frequency drives adjust power based on load. Waste heat recovery and optimised drying cycles are becoming standard.

LiSEC has committed to resource‑saving machines (IGD‑A, LiTEC Temperature Control) and received EcoVadis bronze for sustainability. The TPA line’s intelligent control reduces energy use by 30%, as confirmed by Chongzheng Shengda.

Large‑Format & Ultra‑Thin Glass Processing

Architectural demand for expansive glazing drives the need for equipment that can handle oversized units. The 8 × 3.3 m TPA line and 96‑m jumbo line are examples. For extreme cases, LiSEC can produce 12‑m IGUs without defects.

Simultaneously, ultra‑thin glass (0.5–0.7 mm) is gaining traction for lightweight, high‑performance triple glazing. Glaston’s ULTRA TPS® automates this process, while HEGLA offers automated cutting and handling lines capable of producing 0.4–0.6 million IGUs per year per line.

Addressing Customer Pain Points: Practical Solutions

Pain Point #1 – High Labour Costs & Skill Shortages

Problem: IG lines consume the most manpower; skilled operators are hard to find.

Solution: Invest in fully automatic lines with robotic handling, automatic loading/unloading, and MES integration. Examples: Hanjiang intelligent line, LiSEC TPA, Glaston TPS® PRO. These reduce labour by 60–70% and minimise dependence on manual skills.

Pain Point #2 – Energy Bills

Problem: Drying, tempering, and curing are energy‑intensive.

Solution: Choose equipment with convection heating, variable‑speed motors, and heat recovery. Glaston’s carbon‑fibre impeller saves up to 20% cooling energy; TPA lines save up to 30% overall. Also consider upgrade packages for existing lines to improve efficiency without full replacement.

Pain Point #3 – Quality Inconsistency & Scrap

Problem: Uneven sealant, spacer misalignment, gas leakage cause rejects and complaints.

Solution: Automated systems with real‑time vision inspection, servo‑controlled positioning, and calibrated gas sensors ensure repeatable quality. Forel’s Production Buffer prevents deformation of wide spacers. 4SG lines with seamless corner welding extend warranty to 25 years by eliminating argon leakage.

Pain Point #4 – Inflexibility & Long Changeovers

Problem: Traditional lines cannot quickly switch between sizes, shapes, or spacer types.

Solution: TPS/TPA systems allow changeover during production with no downtime. Dual‑applicator configurations (like Schollglas) enable different spacer materials on the same line. Hanjiang’s intelligent line is designed for small‑batch, customised orders with rapid recipe changes.

Pain Point #5 – Handling Oversized or Specialty Glass

Problem: Many plants cannot process jumbo panels or complex shapes.

Solution: Look for suppliers offering customised jumbo lines (e.g., LiSEC 8×3.3 m, Jinan Lijiang 3300×7000 mm dual‑plate press). Ensure the line can handle curved, trapezoidal, or offset IGUs. For extreme sizes, verify maximum dimensions and weight capacity (e.g., 1.5‑ton panels).
