HANJIANG Super Spacer Applicator: Technology empowers Insulating Glass Production

The Era of Warm Edge Spacers is Here: Time to Redefine Insulating Glass Manufacturing

In the glass processing industry, insulated glass unit(IGU) production has always been a complex and multi- steps process. It involves assembling multiple glass layers with spacer bar, desiccant, primary and secondary sealants, and sometimes filling the cavity with air, argon, or Krypton. Spacer types alone vary greatly, making IG production an intricate art. This article introduces the benefits of using super spacers in IG production and how HANJIANG is empowering warm-edge technology.

Advancements in Automation
Compared to traditional rigid spacers that require cutting/bending, desiccant filling, butyl application, and manual sticking onto glass, HANJIANG’s Super Spacer Applicator (SSA)  simplifies the process by automatically applying spacers onto glass in a single step. This automation significantly reduces the number of production steps and labor involvement, leading to enhanced efficiency and a decrease in product defects due to human intervention.

HANJIANG’s SSSA machine is equipped with a dual-head design and features a unique adjustable cutting head. Each applicator head can store two different sizes of spacers, allowing the entire machine to accommodate up to four distinct spacer widths. This feature is especially advantageous in the production of triple-pane, dual-chamber IGUs where spacers of varying widths are required, particularly in the range of 8mm to 24mm, overcoming challenges in handling ultra-thick spacers between 20mm and 24mm.

The adjustable cutting head further enhances precision in the processing of irregular shapes, achieving highly accurate corner placements for complex designs. This capability makes the SSA ideal for producing double-, triple-, and even quadruple-layer IGUs, with the flexibility to handle various sizes of large-format and irregular-shaped glass.

Notably, in the production of multi-layer (3-5 layers) and oversized glass units, the SSA ensures precise spacer placement, significantly improving the frame adhesion quality. Highly uniform primary sealant and precise placement of spacers are critical, especially in the production of multi-pane and jumbo insulated glass. These elements finally contribute on the quality of IGUs and the overall yield.

High Performance and Energy Efficiency
In high-end windows and curtain walls, energy efficiency is paramount. Super spacers meet the highest thermal performance standards (phA and phA+) set by Germany’s Passive House Institute (PHI) and are suitable for all climate zones worldwide. With HANJIANG’s online Argon filling IG line and defect detection system-Line Eyes, the equipment can achieve up to 90%-95% pure Argon filling, significantly lowering the U-value of IG units for optimal energy efficiency.

Jumbo and Thick IGU
As window and curtain wall glass grows larger and thicker, the demand for high-quality, large-format IG units increases. HANJIANG’s oversized super spacer production lines support dimensions of up to 3×6 meters and even 3.6×10 meters. The system features high-load transportation, high quality washing, and precise primary sealant and  spacer application to ensure both high-quality output and production speed. It is ideal for processing complex triple or four-sided jumbo IGUs.

Economic Efficiency and Return on Investment
While the initial investment in SSA is higher, it brings significant efficiency and quality advantages in producing large, high-value glass products. For IGUs exceeding 2000×3000 mm, this technology offers superior cost-effectiveness and differentiation in a competitive market.

In today’s competitive landscape, HANJIANG provides more than just production equipment—it delivers a sustainable, automated, and intelligent production solution. We invite you to join us in exploring the future of warm-edge technology and smart manufacturing.
